On the receiving side: consider switching to an embedded Perl trap handler which saves snmptrapd from forking on every notification. Depending on your package, you may need to rebuild net-snmp with embedded Perl support. Run "snmptrapd -H 2>&1 | grep -i perl" to find out if snmptrapd supports the "perl" config token. On the sender side: switch to SNMP INFORM instead of SNMP TRAP. The sender is expected to re-transmit the notification if it doesn't get a response, then. +Thomas ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
