SNMP manager does not receive traps

[vedadramovic]

I have configured on a windows test platform WinCCOOA project Version V3.14 with SNMP manager.
It receives SNMP traps in internal datapoint normally.

When the same project configuration is applied on linux platform, SNMP traps are not written in internal data point.

SNMP agent is the same in both cases, and SNMP traps are received on linux computer (they are trapped by tcpdump).

Here is log from linux based SNMP manager

Can you help me?

[agruber]

as far as I know you cannot simply bind privileged ports (

[vedadramovic]

you are right, default SNMP trap port 162 is privileged port on linux.
After transfering SNMP trap port to higher value it is working fine on linux.
Thank you very much Andreas.
