Re: Re: Re:Re: Capabilties of pass command in snmpd.conf?

That message is because you're returning the OID the agent is asking for on 
a getnext command. You should be returning the next OID from the one it's 
asking for when it's a getnext command. So basically your script needs to 
return different OIDs based on whether it's a get or a getnext. When you're 
out of OIDs, you should return nothing.

Hope this helps.
