MRTG and Multihomed NIC

[Khemera Lin]

Thanks for your response, Anthony. Yes, that is what I use. And here is the
output:

# /usr/bin/cfgmaker --global "WorkDir: /var/www/mrtg/fw" --global "YTics[_]:
8" --global "Options[_]: growright,bits" --ifref=ip public at localhost

########
...
...
--snpo: confcache public at localhost: Ip N.N.N.1 --> 5
--snpo: confcache public at localhost: Ip N.N.N.9 --> 5
--snpo: confcache public at localhost: Ip N.N.N.17 --> 5
--snpo: confcache public at localhost: Ip N.N.N.25 --> 5
--snpo: confcache public at localhost: Ip N.N.N.33 --> 5
...
...
########

I have 5 different network interfaces and the fifth one is multihomed to
have multiple IPs on it. As shown above, the cfgmaker could detect all of
the IPs (masked with N.N.N.), but the mrtg.cfg would not have separate
entries for those IPs; it only treats all of them as one single
IP/interface.

Any more ideas please?

Thanks,
Khem

add ifref=ip to your cfgmaker line. mrtg tries to collect info on all 
ips it finds using snmp.  you'll need snmpd configured by using 
/etc/snmp/snmpd.conf.
