Hi

I have been using snmp for 'years' but never came accross this issue before.

On starting i get this

Apr 17 15:42:20 server snmpd: snmpd startup succeeded
Apr 17 15:42:21 server snmpd[29630]: Error opening specified endpoint 
"udp:161"
Apr 17 15:42:21 server snmpd[29630]: Server Exiting with code 1

i have googled this but cant find a solution - does anyone have any hints?

thanks
