Hi guys

I have six linux Centos 5.0 Servers.
I had to configure the snmp client.

I just created a pretty basic configuration


snmpd.conf file
I installed all of these

lm_sensors-2.10.7-4.el5.i386.rpm
net-snmp-libs-5.3.2.2-7.el5.i386.rpm
net-snmp-5.3.2.2-7.el5.i386.rpm
net-snmp-utils-5.3.2.2-7.el5.i386.rpm

4 of them are working fine, the application installed on 10.1.1.10 can query 4 servers but I got 2 Linux Centos that are in a DMZ, and my networking team already opened ports and configured NAT but the SNMP Server 10.1.1.10 is not able to query them

any idea?


how can I check the snmpd is really running apart from service snmpd status?
might be related with the DMZ configuration?

thanks a lot

Do the servers in the dmz see the connection coming from an internal address or the firewall itself or an external address of some kind? (I know silly question, but ... I've seen some screwy stuff.)

I think that's the issue

after checking logs I saw different IP address related with SNMP so I used the NAT IP and reconfigured today some people are going to test that thanks a lot

No problem, with that simple of a config it almost has to be related to the ip the connection is coming from or a firewall (either locally or on the network) between them.
