you can run tcpdump and monitor teh traffic on the wire to see if the messages are in fact being sent to the snmp trap server.

Marco,

Also check the messages file on the remote machine. What you'll find is that if something is polling snmp info on the machine and failing it might have an error as to why...

... that is of course should it be getting there at all. If you've got no errors in the messages file then I'd start thinking about what Donny suggests and get a packet sniffer on the box. If the remote machine is Solaris use the snoop command, if it's HP-UX get tcpdump as Donny suggested. Failing all that ask you networks team (if you have one) to set up a packet sniffer for you between the boxes...

Thanks both for your comments, i tryed to find the tcpdump command but i didnÂ´t find it. Im using hp-ux 11i. Â¿is this command contained in a special patch o someting like that?
Unfortunally, we dont have a sniffer box,

tcpdump doesn't come with HP-UX. You'll have to download it...

Try here, at least it's from the HP porting site so it should be ok...

As I said this will help you capture the network packets and see if your host is actually receiving the request.

Was there anything in the syslog.log file about snmp errors? Please check.
