Re: pass through not working in snmpd
Hi Dave, It seems it was the user issue, I removed the "-u snmp" from /etc/init.d/snmpd, but forgot to remove it from /etc/default/snmpd . Now it's removed and it looks like it's working, Thanks alot! Daniel.

Re: pass through not working in snmpd
Hi Dave, All the directories are 777 or 755 (I checked one by one). /mnt/usb/project/bin/snmp is a soft link to a binary file, I tried putting the binary file there directly, and also tried a shell scripts that prints to a file that it ran (but it didn't print anything). Evenatually I want it to be a shell script (but for now its binary). Any guesses? Thanks, Daniel.

Rather than a "response" packet? That sounds as if the request is being rejected (as part of the SNMPv3 processing) before it gets as far as the varbind processing. Are you sure that the agent isn't logging any sort of error? It might be worth running the agent using '-Dsnmpv3' to see if that shows anything useful.

Does the binary use shared libraries? It might be worth checking the permissions on those as well. What user does the agent run as? Can you run the binary (from the command line) as that same user? > Any guesses? As an alternative approach, try running the agent using the option -Ducd-snmp/pass and re-run the snmpset command.
