Sorry for the slowness on the obviousness of your question.... no... eth1 does not exist... it only has the one card...

I don't understand why it would come up with the same error for both eth0 and eth1.

One thing that I want to try is access a windows machine for snmp information from my linux laptop. This way I can tell if my router is blocking such signals or ports.

Yes. Most of the work I do on the server is done as root. Would this cause the problem?

Ok... I installed MIB browser on the windows machine and pointed it to the address: 127.0.0.1.... but nothing came up.. so... i know the agent isn't working there...

I installed MIB browser on my linux desktop and did a 127.0.0.1 and it worked... so... I also did the server address and it came up as well... so I know that the snmp signals can go through the router...

when i log into the cacti server to add devices... it does the search and doesn't find anything... even though snmp agent is working on my linux desktop...

Would this mean security is set in server blocking snmp?

Talking [success]

Hello Acid_Kewpie

At last, I finally figured this thing out. Very slow... process of discovery... mind you, I only worked at it maybe a few hours a week.

My solution was to keep everything to public... and then enter the IP address for HostName...

I want to change HostName in the snmpd.conf but not to sure which entry to adjust. This is where I think I need to change it:

# Here is a commented out example configuration that allows less
# restrictive access.

# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY
# KNOWN AT YOUR SITE. YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO
# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.

## sec.name source community
#com2sec local localhost COMMUNITY
#com2sec mynetwork NETWORK/24 COMMUNITY

## group.name sec.model sec.name
#group MyRWGroup any local
#group MyROGroup any mynetwork

This way I don't have to keep entering my ip address since my network is setup with a dynamic configuration. Is the red item the one I change?

Hello again.

I figured this one out also. Now I just need to figure out how to get cacti to identify the systems by hostname instead of ip address. Just such a hassle in a dynamic environment. Any suggestions?
