If the /usr/OV/bin/snmpwalk is timing out, more than likely agent is not recognizing the community script being send by command.

Below are two sample snmpd.conf files I have used with Red Hat 3.0.
SAMPLE 1 , I found to work with Red Hat 3.0 Update 4 applied
SAMPLE 2 , Works with Red Hat 3.0 Update 3.

Also there is a note in FIX PACK 2 Readme under "Software required for the new full image Linix CD", in regards to the version of net-snmp found to work with NetView  net-snmp 5.0.9-2.30  It was found that earlier version had a indexing problem between the ip and interface mib tables.

[nv-l] RedHat Snmpd ?

Hello List,
I am running Netview 7.1.4 FP2 on AIX 5.2 ML04.
I have several linux servers and they are all show up as non-snmp.  I have call opened with Red Hat.  These servers are running RedHat ES3. I've checked the snmpd.conf file on linux servers (and made a few changes per RH tech). I do an snmpwalk from the Netview and it just times out. I check the /var/log/messages on linux and it shows the requests coming in from Netview but nothing is returned/replied.
Another strange thing is the messages are only logged when I restart snmpd (and then I do an smpwalk from Netview). So If I restart snmpd (linux server), then I do an snmpwalk from Netview, the message file shows "Received SNMP packet..", then it times out. I do another snmpwalk (also times out) and I do not get another "received snmp" in the /log/message file.
Any suggestions?
