I can create an SSH connection to a a # particular host inside the firewall on port 22 though. # What I was thinking of doing was SSH'ing to that # machine and forwarding a local port to the required # port on the management station inside the firewall. I # thought this was port 162 but when I try and send the # test trap I don't receive anything in the management # console. Can anyone offer any help here? According to: http://www.rad.com/networks/1995/snmp/snmp.htm SNMP works over UDP rather than TCP and I'm believe that SSH is only able to forward TCP data but not UDP. -- Linh Pham lplist@closedsrc.org Webmaster and FreeBSD Geek http://closedsrc.org closedsrc.org Every solution breeds new problems To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
