Error doing snmp_open()

[Icenode]

got same problem here
i had 3 switch cisco
2 switches are good but another one is not connect Timeout while connecting to [x.x.x.x:161]
these 3 switches are separated,weren't grouped in any tamplates
otherwise,i'm sure that items in my unmonitored switch are well-configured ( community string,key,...), as well as cconfiguration in that switch
so, any idea ?

Vin, my problems were absolute and not specific to a single host/device. I was able to resolve by uninstalling an incompatible NET-SNMP package and installing a supported package.

I seem to remember running across a few threads with problems more similar to yours in my search for an answer. Only one I have a link to right now is this one that Ruswold included in this thread.

Solved for me: Had to do the following

Spent a ton of time looking for a solution to this problem on freebsd. I eventually resorted to looking at the Russian zabbix threads and translating them via google translate.

Here is the solution.

Edit "/usr/local/etc/zabbix/zabbix_server.conf"

comment out "SourceIP=x.x.x.x"

restart zabbix and wallah snmp starts working!
