Install MRTG on Debian

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:

1. Snmp dan Snmpd SNMP and Snmpd
2. 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
sysObjectID.0 = OID: netSnmpAgentOIDs.10
sysUpTimeInstance = Timeticks: (29668961) 3 days, 10:24:49.61
sysContact.0 = STRING: admin
sysName.0 = STRING: jenmannii

root@jenmanni:~# vim /etc/snmp/snmpd.conf

I must be edited in the command:

#sec.name source community
com2sec readonly localhost public12
com2sec readonly 203.190.40.0/24 public23
com2sec readonly 192.168.11.1/32 public23

then restart snmp with the command:

root@tyr:~# /etc/init.d/snmpd restart

root@tyr:~# cfgmaker public12@localhost > /etc/mrtg.cfg

root@tyr:~# snmpwalk -Os -c public12 -v 1 localhost system

root@tyr:~# cfgmaker public12@localhost > /etc/mrtg.cfg
root@tyr:~# indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

than open file /etc/mrtg.cfg and at:

# to get bits instead of bytes and graphs growing to the right
Options[_]: growright, bits <<>

to test, mrtg running well, please open browser and type url : http://ip_address/mrtg.

the grow traffik run from left to right.
