Hello,

Can someone explain why I don't get a timeout when I use the community string "public" even if I don't have it defined in my snmpd.conf file. It doesn't return data but it also doesn't timeout. See example below. ... rocommunity nobody 127.0.0.1 ...

[root@L703108 pgsql]# snmpwalk -v 1 -c public 127.0.0.1 1.3.6.1.2.1.2.2.1 ifMIB

[root@L703108 pgsql]# snmpwalk -v 1 -c xyz 127.0.0.1 1.3.6.1.2.1.2.2.1 ifMIB Timeout: No Response from 127.0.0.1

[root@L703108 pgsql]# snmpwalk -v 1 -c nobody 127.0.0.1 1.3.6.1.2.1.2.2.1 ifMIB IF-MIB::ifIndex.1 = INTEGER: 1 IF-MIB::ifIndex.2 = INTEGER: 2 IF-MIB::ifIndex.3 = INTEGER: 3 IF-MIB::ifIndex.4 = INTEGER: 4 IF-MIB::ifIndex.5 = INTEGER: 5 IF-MIB::ifIndex.6 = INTEGER: 6 ...

The default /etc/snmp/snmpd.conf file comes with this line at the top:

com2sec local localhost public

Comment it out, service snmpd reload, and you'll no longer have the problem.

That was it - I guess I didn't read the man page well enough. I was providing my own config file with the -c fname option but the default file was being picked up also since I didn't also specify -C option.

Thanks,
