Mrtg Problem

Hi there,

I've got a little problem with mrtg ...

----- This is my mrtg.cfg file -----

I have 2 ethernet cards in my computer (eth0 - connected to the adsl modem
[172.16.0.1 - helium.home.lan] / eth1 - connected to the lan hub
[172.16.0.7 - argon.home.lan])

I'm realy a newbie in mrtg and I can't resolve the problem with the manuals
:( Is it possible to get help? I understand what the keywords Suppress are
for but this target I don't understand and I suppose the problem is there?

Thank you in advance!

Sure it's an mrtg problem? What happens when you try
to manually access the snmp agent on helium.home.lan
with a community name of 'public'..? from the same host
where you run mrtg.. By 'manually' I mean from a shell
via an snmpget or snmpwalk...

Well I tried and there was also an error so it is snmp which reports the
errors? Look at my actions below (first I missed to start the daemon -
because snmp wasn't installed before, I installed the rpm and didn"t reboot
or restart any other daemon):


Timeout: No Response from helium.home.lan.

Starting snmpd: [  OK  ]

Timeout: No Response from helium.home.lan.

But I can ping helium.home.lan (0% of packages lost) and the domain is also
in the zone file (running ok) ...

ping helium & nslookup works fine ...

Any other ideas?

David

Sounds like snmpd isn't set up. Look at some docs on how to do this. There
are a few settings you need to make in snmpd.conf.

I had the exact problem you had, till I fixed the snmp daemon.

Regards,

Adam.

The problem isn't with MRTG, its with the UCD SNMP daemon config file
that is distributed with RedHat systems as the default.  Its broken.

If you simply delete /etc/snmp.conf completely, it will default to the
behaviour that you are expecting.  While you're at it, send in a
complaint to RedHat about their broken UCD config file, which has been
that way ever since they switched to the UCD version.  Everybody except
RedHat seems to know about this problem with their distribution.

.. everybody except me.. Remember wasting an entire day repairing said
broken file.. But wouldn't you need to create some kind of config file any
way.. at least to change the community names.. and possibly set up some
kind of acl's..? Or maybe the broken file is just Red Hat's new security
strategy..? If it don't work then it can't brake anything... Just kiddin'..

You install from RPM or from source, if source check you have all the Perl
modules you need.

Have you other MRTG logging working but only this one is failing?

Take a look at RRDTool, link of Tobi's MRTG site under Advanced. Faster,
better more reliable, more configurable and selectable (but no included,
choice of website) frontends. Using RRDTool for around 2500 nodes (ports)
on a large Cisco network with no problems.
