I'm sorry David....well the switch is some ghetto switch that only uses snmp to send logs....why in the hell it doesn't use syslog is my guess as well....trust me I'd rather light the thing on fire and throw it out the window then have to deal with this.
Ok let me start from scratch.....I'm on a centos 6.4 linux box and you can yum install net-snmp and net-snmp-utils when configuring the package you just give it a secure community name that basically identifies that server. So on the device side you want to send the snmp stuff to you have to define the community name and ip address to where it goes.....so I did that...it works...the only thing is trying to figure out how to get the traffic into a readable file :/ -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Lang Sent: Thursday, April 11, 2013 12:59 PM To: rsyslog-users Subject: Re: [rsyslog] snmp on linux with rsyslog On Thu, 11 Apr 2013, Josh Bitto wrote: > Ok so I go to load the Module omsnmp and I get an error in syslog that > omsnmp.so in /lib64 not found.....So I downloaded the source from here > http://www.rsyslog.com/files/download/rsyslog/rsyslog-7.2.6.tar.gz > > To just try and grab the omsnmp.so file (I think I would have to > compile to be able to get that file) > > Anywho Rainer you're on the right track.

SNMP Traps would be a very poor fallback if what you are wanting is log messages, assuming you could make it work. > So on the switch side I just gave it the community name and ip address and > criteria to send.... > > > In the snmpd.conf on the server side the only thing that is setup is > the community name and the service is running.

I'm sorry if it seems like I'm making you jump through hoops here, but your questions usually lack so much context that I am having to try and guess what you are really trying to get done and why.
