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 at L703108 pgsql]# snmpwalk -v 1 -c public 127.0.0.1 1.3.6.1.2.1.2.2.1
ifMIB

[root at 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 at 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.
