Problems with SNMPv3

Post by heckfy »

I'm trying to setup a device, it has SNMP v3 and a string like this works (i replaced the real keys with xxxx):

snmpget -l AuthPriv -a SHA -A xxxx -x AES -X xxxx 10.18.4.14 -u nagios DISMAN-EVENT-MIB::sysUpTimeInstance

It doesn't have any password, just the SHA and the AES keys.

However, I'm getting errors like these:

Code: Select all

It probably has something to do with the fact I don't have any password, but I'm not sure.

This is 0.8.8a. Could anyone give me any suggestions what is going on and how to get it working?

Thanks a lot!

Ok, I figured out that the password was in the wrong field, but it's still not working. See the screenshot attached.

I actually see some snmp traffic in tcpdump:

Re: Problems with SNMPv3

Post by heckfy »

Ok, the problem has been resolved. Apparently CentOS 5.8 comes with php 5.1 which doesn't work well with SNMP v3. Upgrading to PHP 5.3.3 solved the problem.
