How to find SNMP community string?

Question

I've been trying to find the SNMP community string in Ubuntu here, but haven't had much luck.

I'm using Ubuntu 12.10 and have followed the instructions here, but my /etc/snmp/snmpd.conf file has different contents than what they're talking about.

Their snmpd.conf file contains: rocommunity [community string]

Mine contains: rocommunity public default -V systemonly

That being the case, what is my community string?

Thanks!

Solution

rocommunity public default -V systemonly

Your read-only community string is public. default represents what traffic will be accepted, which is to say all traffic will be accepted. Change default to be a hostname or a network address and slash annotated subnet to restrict it further (e.g. 10.4.0.0/16). The read-only context will be restricted to the -V systemonly context which means only OIDS .1.3.6.1.2.1.1 and .1.3.6.1.2.1.25.1 will be visible.

You can set it to whatever you'd like.

@Wesley - Sorry about that. I just really needed an answer quick for work and wasn't getting any responses over on askubuntu.

@Hank-Roughknuckles Not getting answers on AskUbuntu is a common theme there. I'll put my answer over there as well since there's no way to mark a question / answer as a duplicate across different StackExchange sites. You can mark this as the answer both here and there to help future readers.
