Squid Password with htpassword

2012-01-29T03:44:00.000+07:00

Today a successful configure squid in Ubuntu Server 11:10 and actually, once the basic settings yet there is something special, just re-read guide that is in here and here .

The next step I tried was mempassword squidnya, so that when people access, despite connect wirelessly browsing when will be forced to login with the username and password that have been made using htpassword.

How to enable htpassword first is to install apache2, how to use apt-get it, and I use NCSA Authentication Helper. Follow the steps as follows:

1. Creating a directory to store the Username and Password htpasswordnya.

eg: # mkdir / usr / lib / squid / NCSA / / * is intended spy a directory with squidnya.

2. Run the command htpassword directly from the terminal, eg:

~ # Htpasswd-c / usr / lib / squid / NCSA / login.auth dobelden / / *-c option to create the user first, if you will add a user, the same command without the-c it.

The command above means that we make direktoru login.auth and user dobelden, when there will dienter enter the new password command, follow it.

3. Setting Edit / etc / squid / squid.conf in the following sections:

auth_param basic realm Squid-Proxy-Server
auth_param basic program / usr / lib / squid / ncsa_auth / usr / lib / squid / NCSA / login.auth
auth_param basic children 5
2 hours auth_param basic credentialsttl
auth_param basic caseSensitive off
REQUIRED acl ncsa_users proxy_auth

4. On the local network http_access http_access below us, attach:

http_access allow ncsa_users

After that restart squidnya, and please be tested with external connection, or from our external network, by installing a manual on the internet browser options, when in Firefox in the Menu-Option-Option-Advanced-Network-Settings and enter our proxy server IP and test by browsing, viewing requests when existing Username and Password settings brarti we've succeeded.

Thus the way of preference, may be useful.

On 29 April 2010 was at 10.4 or ubuntu release tenarnya name Lucid Lynx, who many features offered as additional features, who I like is the view bootscreennya who become citizens of purple not brown anymore. On the desktop wallpaper is also no option like windows aero which could walpapernya alternate view.

Lucid Lynx on Ubuntu-based desktop, we are provided with access when it would make the turn when we need a repository for updates / install packages.

To select a repository is recommended for use there in the local repository (Indonesia) Indonesian people for our course, and the existing software ubuntu repository sources list Indonesia, who I currently use is a repository of kambing.ui.ac.id / ubuntu.

Vicarious step, select the System-Administration-Software Sources to display showing the following:

Then select the part softawe ubuntu-Download from his bow at the click until the option appears, select Other and search for Indonesia-kambing.ui.ac.id territory, such as the following picture:

Then choose the server and load, wait until the process is complete, and there we are using the Repository of kambing.ui.ac.id

Install Cairo dock on Ubuntu Lucid Lynx

2010-03-27T10:04:00.002+07:00

Cairo-Dock is an animated application launch bar for the desktop, comparable to the dock in Mac OS X or Rocket Dock (for Windows). Now, you can use Cairo-Dock with OpenGL.

In previus version we have to add another repository to install Cairo-Dock, but with Ubuntu Lucid Lynx we just go simple install.
First we check the availability Cairo-Dock with this command : apt-cache search cairo-dock, an the result like this :
lucid@lucid-laptop:~$ apt-cache search cairo-dock
cairo-dock - A light and eye-candy dock to launch your programs (metapackage)
cairo-dock-core - A light and eye-candy dock to launch your programs (core package)
cairo-dock-data - A light and eye-candy dock to launch your programs (common files)
cairo-dock-dev - A light and eye-candy dock to launch your programs (dev package)
cairo-dock-plug-ins - A set of plug-ins for cairo-dock
cairo-dock-plug-ins-data - Common files for cairo-dock-plug-ins
cairo-dock-plug-ins-integration - Two plug-ins for cairo-dock for a better integration in GNOME or Xfce
docky - Elegant, powerful, clean dock
python-docky - Elegant, powerful, clean dock - Python support library,

Thereis cairo-dock appear, next just run : aptitude install cairo-dock, the Cairo Dock will be installed on your ubuntu with it depedencies. After finished we can run this application with choose : Application --Accessories--GLX-Dock. To make Cairo Dock Auto run on startup, just go to System--Preferences--Startup Application, then add launcher for Cairo Dock.

Tasksel For Simple Installation

2010-03-26T13:31:00.001+07:00

Tasksel is an installation system that is an integral part of the Debian installer (it is also included in Ubuntu). Tasksel groups software packages by tasks and offers an easy way to install all the packages needed for that task. It provides the same functionality as using conventional meta-packages.

Tasks List

Tasks are defined in .desc files found in /usr/share/tasksel. Debian derivatives can easily add tasks.

The default list available in Ubuntu can be viewed with this command-line:

gedit /usr/share/tasksel/ubuntu-tasks.desc

Installation

tasksel has been included as part of the base installation since Ubuntu 6.10 (Edgy). Tasksel is present on all versions of Ubuntu's installer (but previously was not installed as part of the base system).

Usage

To run tasksel from the command line, type:

sudo tasksel

the tasksel menu will be shown:

Already-installed tasks will have an asterisk beside their name. Select a task by scrolling down and pressing space. This will put an asterisk beside the selected task and mark it for installation. Removing an asterisk marks the task for removal. Once "ok" is selected the task installations and/or removals will take place using apt-get.

Command line arguments

You can also directly specify which task to install.

For instance, to add the Apache-MySQL-PHP stack to an existing system:

sudo tasksel install lamp-server

For complete options, see the tasksel manpage:

man tasksel

Usage (alternative)

NOTE - Calling tasks from apt-get is not documented anywhere. If you find a page that documents this, please update this page with a link.

One can alternatively install tasks with apt-get. This is the syntax:

sudo apt-get install the_name_of_the_task_you_want^

And yes, you forgot the caret (^), and yes, it is magical.

Examples:

sudo apt-get install ubuntu-desktop^ sudo apt-get install kubuntu-desktop^ sudo apt-get install lamp-server^

Task descriptions

Here are the long descriptions of a few common tasks:

dns-server

Selects the BIND DNS server and its documentation.

edubuntu-server

This task provides the Edubuntu classroom server.

lamp-server

Selects a ready-made Linux/Apache/MySQL/PHP server.

ubuntu-desktop

This task installs the Ubuntu desktop environment.

ubuntu-live

This task provides the extra packages installed on the Ubuntu LiveCD. It is neither useful nor recommended to install this task in other environments.

Debian Packages Cycle : Package maintenance

2010-02-28T22:08:00.001+07:00

Each Debian software package has a maintainer who keeps track of releases by the "upstream" authors of the software and ensures that the package is compliant with Debian Policy, coheres with the rest of the distribution, and meets the standards of quality of Debian. In relations with users and other developers, the maintainer uses the bug tracking system to follow up on bug reports and fix bugs. Typically, there is only one maintainer for a single package, but increasingly small teams of developers "co-maintain" larger and more complex packages and groups of packages.^[41]

Periodically, a package maintainer makes a release of a package by uploading it to the "incoming" directory of the Debian package archive (or an "upload queue" which periodically batch-transmits packages to the incoming directory). Package uploads are automatically processed to ensure that they are well-formed (all the requisite files are in place) and that the package is digitally signed by a Debian developer usingOpenPGP-compatible software. All Debian developers have public keys.^[42] Packages are signed to be able to reject uploads from hostile outsiders to the project, and to permit accountability in the event that a package contains a serious bug, a violation of policy, or malicious code.

If the package in incoming is found to be validly signed and well-formed, it is installed into the archive into an area called the "pool" and distributed every day to hundreds of mirrors worldwide. Initially, all package uploads accepted into the archive are only available in the "unstable" suite of packages, which contains the most up-to-date version of each package.

However, new code is also untried code, and those packages are only distributed with clear disclaimers. For packages to become candidates for the next "stable" release of the Debian distribution, they first need to be included in the "testing" suite. The requirements for a package to be included in "testing" is that it:^[43]^[44]

Must have been in unstable for the appropriate length of time (the exact duration depends on the "urgency" of the upload)
Must not have a greater number of "release-critical" bugs filed against it than the current version in testing. Release-critical bugs are those bugs which are considered serious enough that they make the package unsuitable for release.
Must be compiled for all release architectures the package claims to support (eg: the i386-specific package gmod can be included in "testing")
All of its dependencies must either be satisfiable by packages already in testing, or be satisfiable by the group of packages which are going to be installed at the same time.
The operation of installing the package into testing must not break any packages currently in testing.

Thus, a release-critical bug in a package on which many packages depend, such as a shared library, may prevent many packages from entering the "testing" area, because that library is considered deficient.

Periodically, the Release Manager publishes guidelines to the developers in order to ready the release, and in accordance with them eventually decides to make a release. This occurs when all important software is reasonably up-to-date in the release-candidate suite for all architectures for which a release is planned, and when any other goals set by the Release Manager have been met. At that time, all packages in the release-candidate suite ("testing") become part of the released suite ("stable").

It is possible for a package – particularly an old, stable, and seldom-updated one – to belong to more than one suite at the same time. The suites are simply collections of pointers into the package "pool" mentioned above.

[edit]Security information and policy

The Debian Project, being free software, handles security policy through public disclosure rather than through security through obscurity. Many advisories are coordinated with other free software vendors and are published the same day a vulnerability is made public. Debian has a security audit team that reviews the archive looking for new or unfixed security bugs. Debian also participates in security standardization efforts: the Debian security advisories are compatible with the Common Vulnerabilities and Exposures (CVE) dictionary, and Debian is represented in the Board of the Open Vulnerability and Assessment Language (OVAL) project.^[45]

The Debian Project offers extensive documentation and tools to harden a Debian installation both manually and automatically.^[46] SELinux(Security-Enhanced Linux) packages are installed by default though not enabled.^[47]

Bootloader Karmic Koala with Grub2

2010-02-14T10:58:00.002+07:00

Today I have finished installing karmic koala, at menu loader many option to log in, and than I thing to remove some loader.

First I go to : /boot/grub/menu.lst , but viola... i cant that at my karmic koala. after googling I can find the problem, the last version of ubuntu use Grub v1 and for ubuntu karmic koala user Grub v2.

what is basicly different between Grub v1 and Grub v2?

menu.lst no longer controls the menu.
'grub.cfg` is now in control of the menu.
grub.cfg is automatically generated by one of the GRUB 2 scripts.
The partition numbering is different.
Stanzas are phrased slightly differently and can't be copied directly from a GRUB 1 menu.lst to grub.cfg. They are pretty close and easy to change, though.

So according to manual from grub v2, i can edit my loader Ubuntu Karmic with : /boot/grub/grub.cfg

### BEGIN /etc/grub.d/10_linux ###

SheevaPlug - a Debian home server in a wall-wart

2010-01-08T08:35:00.003+07:00

Personally I have always been interested in unusual hardware. Coming from a background in electronics, I tend to find "standard" computer hardware rather boring and always like to experiment with stuff that is off the beaten path. So I was thrilled when I found out about the Linux-powered Marvell SheevaPlug and ordered one right away from GlobalScale Technologies for only US$99. My intended project was replacing my ageing and power-hungry home server with this tiny, power-saving device.

System-level decisions

The SheevaPlug (pictured on the left) is an ARM-based computer with a 1.2 GHz processor, 512 MB of RAM and 512 MB of Flash memory, a Gigabit Ethernet port and a USB host connector, all rolled into the tiny form factor of a wall-wart power adapter. It is offered as a development kit in the hope that developers will find cool things to do with it and jump start a new concept called "plug computing". Since its introduction, several web sites have sprung up that provide valuable information to get it up and running for a variety of applications.

Installing Linux on a device like this is nothing like the standard pop-in-a-CD-and-go install process we are accustomed to when installing Linux on a normal PC. For one thing, there is no local user interface in the form of a monitor and keyboard. There is also no CD drive, and the device has no BIOS, instead it has a powerful open-source boot-loader called U-Boot that is quite famous in embedded systems circles.

The SheevaPlug comes with a stripped-down Ubuntu already pre-installed on the Flash drive and, for many uses as a standard file or web server, this may be just fine. But I use my home server as a MythTV backend, and I was surprised to find that the pre-installed Ubuntu does not have any kernel modules installed. This caused my USB TV tuner not to be recognized. I might have been able to hack in the right modules, but since I was going to add an external USB hard drive to store network backups and recorded TV shows anyway, I decided to leave the Ubuntu installation on the Flash drive alone and install a Debian system on the USB hard drive instead.

In case someone would like to install a fresh Ubuntu, it is worth noting that the ARM edition of Ubuntu 9.10 is not compatible with the SheevaPlug processor. Ubuntu 9.10 uses the ARMv6+VFP instruction set, while the SheevaPlug processor can only handle ARMv5 instructions. As far as I know, every other distro with an ARM branch should work though, as does Ubuntu 9.04.

A quick note on running a MythTV backend on the SheevaPlug. While the SheevaPlug has a processor that is quite capable of handling many server-related workloads, it is missing a floating point unit which causes media encoding performance to be pretty poor. In my setup, I only receive over-the-air HDTV, and the incoming MPEG2 stream can be dumped straight to the hard drive without requiring extra encoding. If you were to try to make MythTV on a SheevaPlug record analog TV though, the results would likely be very poor, since the SheevaPlug doesn't have the muscle to handle the required encoding in real time. As always, use the right tool for the task. In my case, not requiring additional encoding, the SheevaPlug handles the backend tasks for both playback of recorded shows and live TV playback with time-shifting just fine.

Installation

After I had already started this project, I found out that there are different ways to install Debian on the SheevaPlug that are probably easier than what I did, but since I didn't use them, I can't comment on them here. Instead I followed the manual bootstrapping procedure described here which is probably harder, but worked well for me nonetheless. The initial step needs to be performed on a different machine that is already running Debian. I didn't follow the procedure to the letter but made some changes to customize my system. For one thing, instead of Debian "unstable", I decided to install Debian "testing". It has a kernel that is recent enough to support my TV tuner (an ATI TV Wonder 600 USB, well supported under Linux), and it is more stable than Debian's "unstable" branch.

I customized /etc/hostname, /etc/network/interfaces and /etc/fstab to fit my network and system. I decided to partition the USB hard drive to have an ext3 system partition, a 1 GB swap partition and use the rest of the drive as a JFS file system that would hold network storage, backups and MythTV recordings. I chose the lesser known JFS file system because it deals well with the large files generated by MythTV and it is well know to be light on CPU usage, a marked advantage for a low-end system like this one. I decided to skip some of the read-only-root recommendations listed in the procedure since I was not using a Flash storage device but a real hard drive.

With my hard drive now set up with the first stage of the bootstrap system, it was time to hook it up to the SheevaPlug and give it a spin. Since I needed to hook up both a USB hard drive and a USB tuner, I had to add an external USB hub to split the one USB connection on the SheevaPlug into four. I do wish the manufacturer would have included a USB hub in the SheevaPlug hardware so more than just one USB connector would be available, but alas, an external hub does the trick.

The SheevaPlug has no connection for a screen, instead the initial console is accessed through a separate USB device connection that provides a virtual serial port. In fact, two virtual serial ports are provided through this connection: one provides JTAG connectivity for very low-level debugging, the other one provides a serial console at 115,200 bps. On a Linux system, these virtual serial ports can be accessed as /dev/ttyUSBx devices, and the serial console ends up being the second device. An inconvenience is that these devices only appear after the SheevaPlug is powered up, so you have to be fast in making your serial terminal connection once the devices appear to be able to stop the automatic bootloader in time.

After changing the bootloader parameters according to the directions in the procedure, I booted and reached a Bash prompt where I could run the second stage of the bootstrap process and the remaining setup. Besides the regular Debian package sources, I also added the debian-multimedia.org repository and was pleasantly surprised how well stocked their ARM repository is. Debian proper has an excellent reputation when it comes to supporting different architectures, but I hadn't expected this to extend to third-party repositories. A MythTV package for ARM was readily available, saving me the lengthy compile-cycle I had been expecting.

Still, I wasn't able to escape compiling entirely. I ran into trouble getting the USB tuner to work, although it is supposed to work just fine under Linux. The kernel always failed to load the firmware, although I had added it according to the instructions, and the kernel could find the file just fine, but then would error out trying to add a duplicate device node. Plugging the tuner in to my netbook running sidux, it worked just fine out of the box. This had me stumped for a while, but eventually I traced the problem down to a difference in how the Debian ARM and x86 kernels are configured. The ARM kernel has an option set to have the I2C device file system compiled into the kernel, while this is a module in the x86 kernel. The USB tuner uses components that connect to each other using the I2C bus, and both the I2C device file system and the TV tuner driver were trying to create device nodes for these components. I solved the issue by having APT download the kernel sources, copying the standard kernel configuration from the /boot directory, changing this troublesome option and recompiling the kernel.

I finished my system by using apt-get to install SSH, Samba, SWAT, MySQL, MythTV, rsync and probably some other stuff I forgot. How to set all these up is beyond the scope of this article and works pretty much the same as on any other Debian system, so plenty of information is available. The only thing that is unusual and that may confuse people is how to run mythtv-setup, since this is a Qt program and the SheevaPlug has no native GUI interface. The answer is that you can use ssh -X to log in to the SheevaPlug with port forwarding, and then when you run mythtv-setup, the user interface will be exported to the machine you're logging in from.

* * * * *
Conclusion

This write-up was intended as a very high-level review of my experience setting up this unusual system, and is by no means a step-by-step walkthrough. There is plenty of detailed information available online on websites such as plugcomputer.org and computingplugs.com that can prove invaluable to get things working on the SheevaPlug. As remarked before, the system is sold as a developer's kit and setting it up is definitely not for the faint of heart or for those who avoid the terminal like the plague. In the end, I had a lot of fun getting this to work and the system is working beautifully. I learned a lot in the process and am amazed yet again at how flexible Debian is as an operating system for just about any computer, even embedded systems like this one.

The status of Intel video drivers for Ubuntu

2009-08-21T08:34:00.000+07:00

Corresponding changes were made to the Linux kernel, including migrating the new Graphics Execution Manager (GEM), which manages video memory, into the mainline kernel beginning with version 2.6.28. Setting graphics resolution, which has traditionally been done as part of the X server, has also been migrated to the kernel. Kernel Mode Setting (KMS) is now enabled by default in the most recent Ubuntu 9.10 alpha release.

The changes in both the Intel driver and the kernel also required changes to X.Org. Even my brief and decidedly less than detailed description of these changes makes it obvious that an awful lot of Linux core code has been undergoing some very major changes during the past year. Sadly, the results have, at least so far, meant that for many users of some of the most popular Linux distributions, performance did not improve. Quite the opposite: performance severely deteriorated and instability was introduced. Some users who upgraded their systems to the latest and greatest version of their favorite distribution found themselves with a system that ran very poorly, crashed frequently, or in some cases, found that X wouldn't work at all. Phoronix described their testing of Ubuntu 9.04 on a Samsung netbook this way: "...a buggy Intel Linux graphics stack led to slow performance, stability issues, screen corruption, and other problems."

I freely admit that I am not an expert on X.Org internals or graphics drivers but I've tried to follow the technical discussions, the issues involved, and how they have impacted Linux distributions. Today we'll look at the state of Intel graphics in several popular distributions, looking both at what went right and what went wrong in recent releases, what progress has been made, and what can be expected from upcoming releases.

Ubuntu 9.04 was released on April 23rd and users with Intel graphics were severely impacted. The Ubuntu forum includes a Jaunty Intel Graphics Performance Guide which offers three possible workarounds, all of which involve upgrading the Intel driver to a 2.7.x release and possibly upgrading the kernel as well. At the end of the guide are responses and reports from Ubuntu users totalling an amazing 107 pages. Glancing through the reports will reveal mixed results. For some users the problems they had experienced were completely resolved. Others reported no improvement. With my Intel Mobile Express 945GME graphics chipset the best I could achieve was either excellent performance but poor stability in the form of system freeze-ups or X crashes, or poor performance and some video corruption but excellent stability. Another workaround is to revert to an older 2.4.1 Intel driver, an approach which was abandoned early on in the forum but which worked reasonably well for me.

In the discussion which follows the Performance Guide, the Ubuntu developers make it clear they will not be porting more recent kernel builds or Intel drivers to 9.04. Development is now focused on solving the problems in time for the release of 9.10 on October 29th.

The third alpha of Ubuntu 9.10 shipped with the latest 2.8.0 Intel driver, X.Org Server 1.6.2 RC1, and a development snapshot of the Linux 2.6.31 kernel. Phoronix reported poor performance test results with this alpha but I found significant improvement on my system. Ubuntu 9.10 alpha 4, released last week, also includes a newer kernel snapshot and the 2.8.0 driver, which no longer supports EXA and DRI1. While enabling UXA and DRI2 caused instability on my system with the 2.7.x drivers I have no such problem with 2.8.0. With 3D animation enabled I do still see some brief video corruption for a second, perhaps less, when a new window is opened, and a corresponding stutter in whatever action is being performed. I wonder if the stutter I see is part of the cause of the poor performance numbers the Phoronix testers saw. Once a window is open performance seems to be very good. I see no problems at all with 2D graphics using the latest Ubuntu 9.10 build. This is the same result I reported in my review of Pardus 2009 last week. Even though this is an early alpha build with some bugs I found Ubuntu 9.10 to already be far more usable than Ubuntu 9.04.

I should mention that Ubuntu 8.04 LTS uses older code and was not affected. Ubuntu Netbook Remix 8.04 was the factory installed OS on my netbook. With all the latest updates it performs flawlessly.

interface configuration in debian lenny

2009-07-24T08:52:00.002+07:00

Debian Lenny not so different with the previous version thereis no significant changes in the interfaces configuration and the command I usually do is I like this :

1. The main interfaces configuration

support@debian ~ $ /etc/network/interfaces

Here is the main input interface in the ip address that we have, such as :

address
netmask
network
broadcast
gateway
dns-servers

2. See the list Ip address

To see list ip address we can use command :

support@debian ~ $ ip a
support@debian ~ $ ifconfig

3. See to up interfaces that connected with network :

support@debian ~ $ mii-tools

with this command we can see the interfaces connected to the network

4. To reconfigure named of interfaces, just edit this file :

support@debian ~ $ vim /etc/udev/rules.d/70_persistent-net.rules

in this file we change our interface name like : eth0 change with : eth1 , etc..

have a try...

News : Debian, Ubuntu and Fedora

2009-07-18T08:16:00.003+07:00

Debian - It has been a hot topic lately - whether Novell's open source implementation of the heavily patented and Microsoft controlled .NET programming framework should be included by default in Linux distributions. The Debian GNU/Linux project recently announced that notetaking program, Tomboy, would be included by default in the package selection for next release, Squeeze. In reply to this announcement, the father of free software Richard Stallman, warned against including Mono by default.

He wrote: "Debian's decision to include Mono in its principal way of installing GNOME, for the sake of Tomboy which is an application written in C#, leads the community in a risky direction." He continued: "The danger is that Microsoft is probably planning to force all free C# implementations underground some day using software patents...This is a serious danger, and only fools would ignore it until the day it actually happens. We need to take precautions now to protect ourselves from this future danger." Official Debian developer Alexander Reichle-Schmehl wrote a reply in his blog, saying:"So, when installing Lenny, and when using the GNOME installation media (not the KDE, Xfce or LXDE one), and when you have either a complete set of discs (including DVD or BlueRay installation) or internet access during installation time, tomboy (and therefore mono) will already be installed automatically.

When using other installation media or only use the first CD (which doesn't contain tomboy) neither tomboy nor mono will be installed." So for now at least, Mono is still not quite included in the default GNOME desktop, but will things change? And does anyone care?

Ubuntu - Also related to Mono, the Ubuntu community has been putting pressure on the project to make an official announcement as to their position on Mono in the popular operating system. This week the Ubuntu Techncal Board granted their wish, although it might not have been the one many were hoping for.

In the announcement, the team writes: "The Ubuntu Project takes patent issues seriously, and the Ubuntu Technical Board is the governance body that handles allegations of patent infringement...The Ubuntu Technical Board has received no claims of infringement against the Mono stack, and is not aware of any such claims having been received by other similar projects." Finally they conclude: "Given the above, the Ubuntu Technical Board sees no reason to exclude Mono or applications based upon it from the archive, or from the default installation set." In short, Ubuntu approves of Mono and will continue to include .NET applications as part of their default install.

Indeed, with the upcoming release they will be increasing the number of these applications by replacing music player Rhythmbox with Banshee.

In other Ubuntu related news, the team behind Ksplice has announced a free service for Ubuntu Jaunty users called Uptrack. Ksplice can apply kernel patches directly into the running kernel, without requiring a reboot.

Linux Magazine has an interesting article about the technology. "Ksplice is a suite of tools which can apply patches directly into a running kernel resulting in an instantly patched system without a single interruption. No need to reboot the system or restart any services!" But would any desktop users really care? "Certainly most desktop users will probably feel that their system is secure enough and not feel the need for such a service.

After all, most desktops rarely face the Internet directly like a server might. Even so, the more layers of security and protection one can have on their system the better. Finally, the Ksplice team really has done a first class job at implementing the technology. It’s just so easy for end users to install and use." The service is available free of charge and users can take advantage of it by downloading and installing the package from their website.

Fedora - Recently the Ubuntu project announced their "One Hundred Paper Cuts" project, to fix niggling issues which negatively impact the user experience on the operating system. Perhaps partially inspired by this project, Fedora has announced their own called "Fit and Finish". The projects page begins: "Fedora is well-known as the premier showcase for the latest open source technology on Linux.

Unfortunately, it has also been perceived as being a bit rough around the edges. The Fedora Fit and Finish initiative intends to change this. We will focus on getting the details right and improving the user experience by removing obstacles and annoyances from everyday tasks." It then goes on to provide a list of examples, including things such as: plugging in a projector and starting a presentation; inserting blank media and getting it formatted; interacting with portable media players, and; sharing files with others on the network. The project aims to work on these for the upcoming release 12. It differs from Ubuntu's by casting the net much wider, instead of limiting it to problems with existing features. Improvements in Linux distributions, whatever they might be, are always a good thing!

Fix Bug : Pidgin Login On Ubuntu Jaunty

2009-06-21T11:59:00.005+07:00

After Yahoo Update his port, many instant messenging like pidgin and kopete cant login with yahoo account.

If you use Ubuntu Jaunty you can try this way to fix this problem :

Ubuntu ships Pidgin but does not update it after a release (except for security issues). For those users who desire new releases of Pidgin, we have packaged Pidgin in a PPA. If you encounter problems with these packages, try building from source and report the bug.

To setup the PPA, copy-and-paste these commands into a terminal:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com \ 67265eb522bdd6b1c69e66ed7fb8bee0a1f196a8

. /etc/lsb-release

echo deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu \ $DISTRIB_CODENAME main | \
sudo tee /etc/apt/sources.list.d/pidgin-ppa.list

Once this PPA is setup, Pidgin updates will show up in Update Manager along with the usual Ubuntu updates. The PPA will need to be re-setup only after upgrading Ubuntu.

Taken from pidgin site.

and after that you have to change your setting on managed account and double click at your username and choose advance. at pager server :scs.msg.yahoo.com change with this : cn.scs.msg.yahoo.com

Fix Problem Dual Boot Debian Lenny and Windows

2009-05-21T16:02:00.003+07:00

Today I try install Debian Lenny on my Laptop, but after all any problem with my windows partition, because grub loader cant load windows system.

To fix it i try search at google and found same problem, from that information I do this step :

According to review from distrowatch, that any criticall packages is not installed why Debian Lenny install, the packages is HAL ( Hardware Abstraction Layer ). This meant that removable media was not automatically mounted. Simply installing the hal package solved this problem.

Just run : ~#apt-get install hal

Next step edit /boot/grub/menu.lst at this row :

title Microsoft Windows XP Professional
root (hd0,0)
savedefault
makeactive
chainloader +1

became :

title Microsoft Windows XP Professional
rootnoverify (hd0,0)
savedefault
makeactive
chainloader +1
just look at italic text, root change with rootnoverify. after that reboot your system and viola... bootloader running well dan you can choose windows boot option.

.htaccess to protect mrtg with password

2009-05-19T10:49:00.003+07:00

At the time of installation such as MRTG on the last post, only the entry on stage to create the look, how authentifikasi not have time to access and this will be prone to keep confidential . . then can use to . htaccess to give a password. But this is the step to do, but before apache condition must exist and running well

First off all we create a user using the passwd and htpasswd, now under the command like this:

$htpasswd -c /etc/apache2/apache-users admin
New password:
Re-type new password:

With the command that will be made with the user name admin and passwd now and there will be a file apache-users, the-c option above is included if you first create a user and passwd to .htaccess.

Then, create a file. Direktory htaccess in you will be protected, in this case is:

/var/www/mrtg/.htaccess

and the contents therein should kata2 this:

AuthName “Rahasia Sendiri”
AuthType Basic
AuthUserFile /etc/apache/apache-users
require valid-user

and make sure permission. htaccess can be accessed by the user will access the mrtg and order .htaccess authentication credentials to be allowed to mrtg, so I must have edited in:

vim /etc/apache/httpd.conf

with the change in part:

AllowOverride none

to be:

AllowOverride AuthConfig

and after disave do not forget to restart apache it. authconfig different settings for the apache and apache2. After that please try to access it with mrtg write: http://myserver/mrtg

Debian Social Contract with the Free Software Community

2009-05-07T16:31:00.001+07:00

ebian, the producers of the Debian GNU/Linux system, have created the Debian Social Contract. The Debian Free Software Guidelines (DFSG) part of the contract, initially designed as a set of commitments that we agree to abide by, has been adopted by the free software community as the basis of the Open Source Definition.

Social Contract with the Free Software Community

Debian will remain 100% free
We provide the guidelines that we use to determine if a work is free in the document entitled The Debian Free Software Guidelines. We promise that the Debian system and all its components will be free according to these guidelines. We will support people who create or use both free and non-free works on Debian. We will never make the system require the use of a non-free component.
We will give back to the free software community
When we write new components of the Debian system, we will license them in a manner consistent with the Debian Free Software Guidelines. We will make the best system we can, so that free works will be widely distributed and used. We will communicate things such as bug fixes, improvements and user requests to the upstream authors of works included in our system.
We will not hide problems
We will keep our entire bug report database open for public view at all times. Reports that people file online will promptly become visible to others.
Our priorities are our users and free software
We will be guided by the needs of our users and the free software community. We will place their interests first in our priorities. We will support the needs of our users for operation in many different kinds of computing environments. We will not object to non-free works that are intended to be used on Debian systems, or attempt to charge a fee to people who create or use such works. We will allow others to create distributions containing both the Debian system and other works, without any fee from us. In furtherance of these goals, we will provide an integrated system of high-quality materials with no legal restrictions that would prevent such uses of the system.
Works that do not meet our free software standards
We acknowledge that some of our users require the use of works that do not conform to the Debian Free Software Guidelines. We have created contrib and non-free areas in our archive for these works. The packages in these areas are not part of the Debian system, although they have been configured for use with Debian. We encourage CD manufacturers to read the licenses of the packages in these areas and determine if they can distribute the packages on their CDs. Thus, although non-free works are not a part of Debian, we support their use and provide infrastructure for non-free packages (such as our bug tracking system and mailing lists).

So lets Free software with Debian...

Install MRTG on Debian

2009-05-05T13:46:00.004+07:00

Sample mrtg interface

Finally I can also install mrtg on debian Etch. Mrtg is Multi Router Traffik Grapher, namely the graph to see traffik can do through us in the router.

Need to install some of the previous packet, namely:

Snmp dan Snmpd SNMP and Snmpd
Mrtg Mrtg

The step-step of installation is:

Because with debian, installation easy to do with how to:

#apt-get install snmp, snmpd, mrtg and let the process run to complete ..

because there is already at cron, so I only do we:

cp /etc/mrtg.cfg /etc/mrtg.cfg.old
cfgmaker passpublic@localhost > /etc/mrtg.cfg
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

note :

passpublic is a community you have in /etc/snmp/snmpd.conf and make sure that snmpd is running well.

To check whether SNMP works correctly, run the following command:
snmpwalk -Os -c passpublic -v 1 localhost system

The above command will produce output like the following:

sysDescr.0 = STRING: Linux frigg 2.6.18-4-686 #1 SMP Mon Mar 26 17:17:36 UTC 2007 i686

Dial Telkom Speedy ADSL with Debian

2009-05-04T20:38:00.003+07:00

Some time there are problems with a modem with TPLINK, namely difficult to PPPoE mode and when it is successful the next difficulty is, when the modem is Dead, he can not autoredial itself, making the resetting with the manual.

Then show him the idea to try using the debian etch, to create the first live one block ip in the router interface in the other one with Modem, and make sure the modem can pinging from debian and the mode of modem is : BRIDGE

The next step is to prepare the packages do support for the process dial adslnya later, while in the package you should install are: pppoe and pppoeconf, installnya enough to run the command:

# apt-get install pppoe pppoeconf (* let the process continue and tetep kelarkan installation *).

Furthermore, if already installed the next step is to configurasi and run the pppoe dial speedynya experiment.

Configurasi file in: /etc/ppp/peers/dsl-provider, nah dsl-provider file in the backup so that when the first dial fail and can be repeated again.

# cd /etc/ppp/peers
# cp dsl-provider dsl-provider.ori

Now we try to do configurasi internet connection, there are some things I needed to help expedite the process of installation, including:

Login name given by ADSL Provider (Speedy).
Password that's also from ADSL Provider (Speedy).
If more than 2 interfaces ensure speedy interface you which direction and when the modem to dial UTP is connected.

Run 'pppoeconf' I have in/usr/sbin:

# cd /usr/sbin #
# pppoeconf # Pppoeconf

* if interface more than one he will choose the interface where you connect to the modem *

Live in only enter Yes, the device will scan information:

If detected you have a modem connected, the display will appear below:

Living in yes, a notification will appear again:

There is a notification message back, as follows:

The next step is to form fill user and passwd fromADSL Provider (Speedy).

view the content of password:

Well here DNS provides the option to add the DNS Speedy in / etc / resolv.conf and then restart each resolv akan still filled by DNS from speedy, that trouble you here I met when I want to make a connection between loadbalance Speedy with a wisp, as they can not rule created a local DNS manually and can not be in the perfect configuration, but if the debian pc to normal, this is not a problem . .

Just chooseYes on the recommendations.

Then there will be a message for the packet size, what if you want to stay in default then yes :

Next message mengenable redeal for speedy restart each debiannya:

The next message you need to be, below:

It is finished configurasi dial speedynya, and does not need to do the same because it has automatic redial speednya.

To prove there is not connection speednya, can diliat with the command:

# ip a or ifconfig

at interface list now we have interface with the name: ppp0, nah this is pppoenya interface.

Wifi Radar : Scan your Free hotspot

2009-05-02T10:12:00.002+07:00

For linux dekstop at laptop, now we can use wireless interface to surf internet, much free hotspot area that we can use and happying browsing.

For scanning and show wireless hotspot signal you can use tools named : Wifi radar.

WiFi Radar is a Python/PyGTK2 utility for managing WiFi profiles on GNU/Linux.

It enables you to scan for available networks and create profiles for your preferred networks. You can drag and drop your preferred networks to arrange the profile priority.

WiFi Radar is tested to work with D-Link AirPlus G on Slackware 12.2 but should work just the same for any iwconfig interface. To use WiFi Radar you need to have the following:

If your laptop running with Debian, Ubuntu, LinuxMint or Operating system similar Debian base, you just install it with apt-get option, like this :

~# apt-get install wifi-radar

Feel free to wait till installing finished, after that you can run at gnome menu - Internet - Wifi Radar, or at console just run :

~# wifi-radar.

and will appear this menu list :

File Server with Samba at Debian Etch

2009-04-12T17:43:00.002+07:00

Communication needs at this time is multiplatform and very prosaic commonplace. Any sample application is data communication between the Windows platform with Linux. In this case I give in Linux by creating a package you can sincronize data communication with the windows.

Samba, that's the package is called, what is samba? What we read from the official site its samba, like this:

Samba is software that can be run on a platform other than Microsoft Windows, for example, UNIX, Linux, IBM System 390, OpenVMS, and other operating systems. Samba is software that can be run on a platform other than Microsoft Windows, for example, UNIX, Linux, IBM System 390, OpenVMS, and other operating systems. Samba uses the TCP/IP protocol that is installed on the host server. Samba uses the TCP / IP protocol that is installed on the host server. When correctly configured, it allows that host to interact with a Microsoft Windows client or server as if it is a Windows file and print server. When correctly configured, it allows that host to interact with a Microsoft Windows client or server as if it is a Windows file and print server.

already described uses samba? well now we will try to install samba via a GNU / Linux Debian.

How to install in Debian is very very easy, simply run the command:

~ # Aptitude install samba

So with all the packages samba and its dependency directly installed. When you are the next steps to set up living alone.

Well here I will try to give examples as needed in a cafe, because it is prone to have the virus in its windows, the computer user only contain the operating system windows are just storing data files stored on the server-based Debian earlier.

Samba in the position of: / etc / samba / smb.conf, just open the file, before what in especial utak settings it's good we just rename the original file, and we make a new pot contents setting samba suit us, me - how to rename done:

~# mv /etc/samba/smb.conf /etc/samba/smb.conf.bak

After that open a new smb.conf file by typing the command:

~# vim /etc/samba/smb.conf

Fill in the file with configurasi below:

Position on the Global Settings:

#======================= Global Settings =======================

[global] [global]

## Browsing/Identification ### # # Browsing / Identification # # #

workgroup = J00NET
netbios name = J00NETserver
server string = %h server (Samba %v)
log file = /var/log/samba/log.%m
max log size = 1000
syslog = 0
guest only = yes
guest ok = yes
####### Authentication #######

security = share

encrypt passwords = true

passdb backend = tdbsam

obey pam restrictions = yes

guest account = nobody guest
invalid users = root

#======================= Share Definitions =======================

[Data User]
path = /a_reserve/DataUser
comment = Share Directories
browseable = yes
writable = yes
public = yes
available = yes

[Multimedia]
path = /b_reserve/Multimedia/
comment = Multimedia Share
browseable = yes
writeable = yes
public = yes
available = yes

Now there are at least 3 pendefinisian in sambanya server, which is the main settings in the Customize Definitionnya, because we will open the folder you can access from windows machine.

Settings in here to do as closely as possible when the user saves the data he was not aware that the data stored on the server in the linux is not windows. With the above files / folders from samba share you can modify in such a way as it is writeable, Readable and Executeable. also omitted elements here include username and password when we access the share file we need.

When you are in the configuration, save and restart sambanya way:

~# /etc/init.d/samba restart.

For testing, please check in at the windows and the server ip sambanya accessed through explorer. Happy Testing

Debian with Code Name Lenny

2009-01-22T11:32:00.003+07:00

After realeased debian with code name etch, now debian launch testing version for new debian "lenny", what is testing? its mean that things should not break as badly as in unstable or experimental distributions, because packages are allowed to enter this distribution only after a certain period of time has passed, and when they don't have any release-critical bugs filed against them.

Please note that security updates for testing distribution are not managed by the security team. Hence, testing does not get security updates in a timely manner.

For more information you can visit official site debian, or at wikipedia.

Daily Command From Debian Etch

2008-12-11T13:19:00.003+07:00

This is the list that I always use when I configure a debian machine :

apt, for this command we can use some job like : apt-get update ( for update your repository that store at : /etc/apt/sources.list, apt-get install [packages name] ( to install packages that we need to install), apt-cdrom add ( to add list repository from CD we have ).
vim, this is a command to edit some file, for example : vim /home/andri/letter, this command mean that we open the file called letter.
cp, to copy file at direcroty to another directory one. example : cp /home/andri/letter /home/iwan/
mv, to move or rename file, example cp /home/andri/letter /home/iwan/letterrename.
ln -s , to make simbolic link
ls -la, to view list file or directory at our active directory
ps -aux, to view running service at our machine

And this the packages that always installed at debian machine :

iftop, to show and know traffik activity
ifstat, like iftop but different in view order
mc, midnight commander tools to copy file like Winscp maybe
rcconf, to show and select or deselect the running service
ipcalc, to calculate ip address

its some command and packages that we need.

Partition size when install Debian

2008-11-27T16:56:00.003+07:00

When I install debian, I always use partition portion like this :

Filesystem Size Used Avail Use% Mounted on
/dev/hda1 7.4G 239M 6.8G 4% /
tmpfs 503M 0 503M 0% /lib/init/rw
udev 10M 56K 10M 1% /dev
tmpfs 503M 0 503M 0% /dev/shm
/dev/hda8 11G 154M 9.5G 2% /cache0
/dev/hda9 11G 154M 9.5G 2% /cache1
/dev/hda7 14G 167M 13G 2% /home
/dev/hda2 3.7G 72M 3.5G 3% /tmp
/dev/hda5 14G 621M 13G 5% /usr
/dev/hda6 14G 414M 13G 4% /var

additional info :

* for swap, I use 2 x RAM if RAM =< 512.

note : this partition is just according to my opinion, and will different portion if other people set the partition.

Sudo Configuration on Debian etch

2008-11-25T16:40:00.003+07:00

Sudo is a program designed to allow a sysadmin to give limited root privileges to users and log root activity. The basic philosophy is to give as few privileges as possible but still allow people to get their work done.

this is the example sudoers configuration at /etc/sudoers :

Defaults env_reset

# Host alias specification

# User alias specification
User_Alias Operator=mike, lula, abel
User_Alias Ordinary=summer
User_Alias ADMIN=debi, ian

# Cmnd alias specification
Cmnd_Alias SU=/bin/su
Cmnd_Alias UIP=/root/script/dialog5
Cmnd_Alias MTR=/usr/bin/mtr
Cmnd_Alias IFTOP=/usr/sbin/iftop
Cmnd_Alias IPTRAF=/usr/bin/iptraf
Cmnd_Alias TAR=/bin/tar
Cmnd_Alias CHATTR=/usr/bin/chattr
Cmnd_Alias VISUDO=/usr/sbin/visudo
Cmnd_Alias FPING=/usr/bin/fping
Cmnd_Alias SHELLS = /bin/sh, /bin/csh, /bin/bash, \
/usr/bin/tcsh, /usr/bin/rsh
# Defaults specification
# User privilege specification
root ALL=(ALL) ALL

# Uncomment to allow people in group wheel to run all commands
# %wheel ALL=(ALL) ALL

# Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL
Operator ALL=(ALL) NOPASSWD: ALL,!SU,!CHATTR,!VISUDO,!SHELLS
Ordinary ALL=(ALL) NOPASSWD: UIP
ADMIN ALL=(ALL) NOPASSWD: ALL

# Samples
# %users ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users localhost=/sbin/shutdown -h now

after edit, please save and restart with this command :
~# /etc/init.d/sudoers restart

the configuration above, especially on this line :

# Same thing without a password
%wheel ALL=(ALL) NOPASSWD: ALL
Operator ALL=(ALL) NOPASSWD: ALL,!SU,!CHATTR,!VISUDO,!SHELLS
Ordinary ALL=(ALL) NOPASSWD: UIP
ADMIN ALL=(ALL) NOPASSWD: ALL

its tell that for Operator, Ordinay and ADMIN have different command and privillages.

a little note : Install Debian Etch

2008-11-24T11:31:00.004+07:00

So here I'll write a little note for the installation, now I need to be considered are:

After the installation do not forget to remove the package's called: network-manager-manager, where the network is by default automatically create a name, this is the server name to make clear that we add in the / etc / resolv.conf will be lost when the server restart.
- for uninstalling the command: apt-get remove network-manager, after the repeat again with the extra-purge: apt-get remove-purge network-manager.
Do not forget to also edit the file / etc / sysctl.conf
- uncomment the following:
Create a folder and file that will be in the execution in networking daemon
- mkdir / etc / folderanda / my-network, communicate the contents of this file is ip address and additional iptables rule, and do not forget change permission, with the command ~# chmod 775 / etc / folderanda / my-network.
- o after that the file / etc / folderanda / my-network, entered dirule: / etc / init.d / networking.
If you have trouble with your ethernet card, and must change that interface, any rule that you must check, because if you change the interface, the name of interface still counting not rearrange ethernet name entry, so you must change the configuration at : ~# /etc/udev/rules.d/z_25persistent-net.rules, delete the content of file n restart your machine, so the interface name recounting from eth0.

Things were usually overlooked when the router settings.

Print with pixma ip1000 at 7:10 ubuntu

2008-11-22T09:02:00.000+07:00

After exhausting struggle's sizable, may also eventually install the printer driver canon pixma ip1000 with success, the steps do I have been very public by friends I work with Ubuntu. the steps I do as below:

The first time I have to do is add the repository in the / etc / apt / source.list

deb http://mambo.kuhp.kyoto-u.ac.jp/~takushi/debian ./
deb-src http://mambo.kuhp.kyoto-u.ac.jp/~takushi/debian ./

then the package is updated to do with the command:

#apt-get update

there are three packages required for running the Canon printer Ip1000 in ubuntu, but because there is ubuntu in the command apt-get install, such as below:

# apt-get install libcnbj-2.2 bjfilter-2.2 pstocanonbj

and when it installed the first time there is a problem, try to be repeated again, because I experienced the same thing, when running the first time I do my work and success once again. to install manually can be tough in here and here.

printernya for configuration:

From the menu select System Administration>> Printing>> New Printer
There will be no local printer and ip1000
Select Forward / Continue
To select Canon Manufacturer
To select the model Pixma iP1000
To select the standard Driver
Apply.
Try printnya test and do not forget to set as the default printer and open openoffice word for test ngeprintnya.

with the above steps do I print a success in ubuntu 7:10 with success. But there is a problem when print job canceled and would remove the queue when the list was in fact the printer option, and it asked to google is also included in the bug, do'h I confuse what must I do, because I cancel 60 pages, but the printer cant stopped printing, fyuh.. .

Step I do is in the printer hardware with the steps below:

Langkah 1: Service Manual ways (means 1)
1. Remove the USB cable and POWER.
2. Open the door of the printer and press + hold the Power button
3.Place the longer the cable POWER
4. Close the door printers, freelance POWER button.
5. Audrey but that was still Blinking

then I open the url printernya dibrowser with the address: http://localhost:631/printers/iP1000, there are many options there, that I do is: cancel all jobs and stop the printer, the printer off and on again, and it is also Blinking, I enter the paper and 5 sheets have been victims blinkingnya stop.

Then click the start printernya print and try again .. and is running well again.

So while, before ngeprint, earned diprint data will not valid to mengcancel printing, and not too many in the queue, because it will make cupsys crash.

hopefully useful for the progress opensource

Learning Linux through the terminal console

2008-11-20T09:45:00.000+07:00

Because I Nyubie in the field of Linux, and sometimes difficult to apply again what I have learned so I try to document them in this blog, the main purpose is no other matter does not forget when you meet the same problems and the broader hopefully there are people who can benefit from this.

In the post this time I will try to pack in the form of FAQ, or frequently asked questions.

Q: How do I go to the root of the ordinary user?

A: In my liveCD Linux like Ubuntu, then when we log on our desktop is not allowed to log in using the root, but the user is the first time installation, while steps are as follows:

- Login using normal user account, "but change from the terminal towards the root login by using the commands: # sudo su - and then enter, so you can look that your console prompt like this :

root@yourmachine:~#

But if you using debian or orther distro, just use command :~# su - then enter, after that the field will appear passwd, then enter a password and enter rootnya.

As the picture below:

and fill a password if it is correct, then will look like this:

When the display is above (the name depends on the name linux nightwish we make, not necessarily the same), then it indicates we have been working with the root user.

Q: To prove we work with the root user with the what?

A: Use the command: nightwish: ~ # pwd, the pwd command will show where our position?

Q: How do I create a folder in linux?

A: Use the command: nightwish: ~ # mkdir, for example:

nightwish: ~ # mkdir / home/denden/mp3 <

nightwish: ~ # chmod 777 / home/denden/mp3 /

to see whether there are changes in the execution of rights in the file / mp3 /

nightwish: ~ # ls-la / home/denden/mp3 / <

total 8 total 8

drwxrwxrwx 2 root root 4096 2008-11-06 12:24 . drwxrwxrwx 2 root root 4096 2008-11-06 12:24.

drwxr-xr-x 5 denden denden 4096 2008-11-06 12:24 .. drwxr-xr-x 5 Denden Denden 4096 2008-11-06 12:24 ..

Q: How do I access the files / folders on the Windows partition?
A: Use the mount, with the first step is to make direktory in / mnt / command, being the same as the folder as above, and to use the mount command:

nightwish: ~ # mount /dev/hda5/mnt/newfolder, when the data partition in the windows / linux hda5 in the data will be visible in /mnt/newfolder.

for while it ahead of me ... and hopefully useful..

About Debian Family

2008-11-06T12:34:00.000+07:00

With this blog, i'll try to create post all about debian n family.

Family means like Ubuntu, Linuxmint and other distro who use default kernel from debian.

So lets see and support me to update this blog, for first i'll translate indonesian artikel to fill this blog.
