RE: snmptrap source ip

Thank you Glenn.

I have tried using the "-Y clientaddr=<ip:port>" flag but with no
success. I also tried setting the "clientaddr" parameter in the
snmp.conf file.
The outcome is always the same - the outgoing port is the same (I have
only one IP on my testing machine so I assume that if I could preset the
port, the ip will be also set.

Please mind I am working with 5.4.1 netsnmp version.

Does snmptrap.exe (windows XP) suppose to be influenced from this
parameter or is it only for snmpd and snmptrapd?
If only for snmpd and snmptrapd, how can I set the source ip of outgoing
traps if I am using the "snmptrap.exe" to send them?

Thanks in advance,

I had a similar problem, but I was generating informs from a subagent on

a machine with multiple interfaces where I needed to ensure informs were

coming from a specific interface.  See the thread starting here:

http://thread.gmane.org/gmane.network.net-snmp.user/25707/focus=25707

I haven't tried it, but I think if you add '--clientaddr=<source_ip>' to

your snmptrap command line it will get you the result you want.
