Cacti

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.

And here is the snmpwalk version of the query shown in cacti debug: [root@cacti ~]# snmpwalk -v3 -u nagios -l AuthPriv -a SHA -A XXXX -x AES -X XXXX 10.18.4.14 .1.3.6.1.2.1.2.1.0 IF-MIB::ifNumber.0 = INTEGER: 141 [root@cacti ~]# rnm@lab-jnpr-core2# Jan 3 19:03:40 snmpd[68a2016b] >>>>>>>>>>>>>>>>>>>>...

Here is debug info: Good query: [root@cacti ~]# snmpwalk -v3 -u nagios -l AuthPriv -a SHA -A XXXXX -x AES -X XXXXXX 10.18.4.14 sysuptime DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (1419446908) 164 days, 6:54:29.08 [root@cacti ~]# switch side debug: [quote]rnm@lab-jnpr-core2# Jan 3 18:59:19 snm...

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

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...
