I'm running Ubuntu 12.10 and I'm trying to find my SNMP community string.

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

  • Their snmpd.conf file: rocommunity [community string]
  • Mine: rocommunity public default -V systemonly

That being the case, what is my community string?

rocommunity public default -V systemonly

Change default to be a hostname or a network address and slash annotated subnet to restrict it further (e.g. The read-only context will be restricted to the -V systemonly context which means only OIDS . and . will be visible.
