Timeout while trying to query a SNMP server

Question

I am trying to perform a query to a snmp server but I always obtain a timeout error. I am working with SLES 11 (OpenSUSE) and the firewall is disabled.

The query I am executin is:

> snmpwalk -mALL -v1 -ccomname localhost system 2 > /dev/null
Timeout: No Response from localhost

I have tried to allow the access to/from snmp by configuring the files hosts.allow and /etc/snmp/snmpd.conf. These files are below:

hosts.allow

snmpd : ALL : ALLOW

snmpd.conf

syslocation Server Room
syscontact Sysadmin (root@localhost)

# These really aren't meant for production use.  They include all MIBS
# and can use considerable resources.  See snmpd.conf(5) for information
# on setting up groups and limiting MIBS.
rocommunity public 127.0.0.1
# rwcommunity mysecret 127.0.0.1

netstat

In addition, I have test that the server is actually listening with netstat:

> sudo netstat -tualpn | grep snmp
tcp        0      0 127.0.0.1:199           0.0.0.0:*               LISTEN      20561/snmpd         
udp        0      0 0.0.0.0:161             0.0.0.0:*                           20561/snmpd

log file

In addition, I have inspected the log file:

NET-SNMP version 5.4.2.1
Connection from UDP: [127.0.0.1]:47705->[127.0.0.1]
Connection from UDP: [127.0.0.1]:47705->[127.0.0.1]
[...]
Connection from UDP: [127.0.0.1]:39362->[127.0.0.1]
Connection from UDP: [127.0.0.1]:39362->[127.0.0.1]
Connection from UDP: [127.0.0.1]:39362->[127.0.0.1]
Connection from UDP: [127.0.0.1]:39362->[127.0.0.1]

I have observed that every time I execute the snmpwalk sentence, 6 entries similar to the above are added to the log.

Solution

The problem was that the community name was wrong, it should be public instead of comname.

I run the snmp configuration to set the community name as comname, but it is still 'public'. I do not know why.
