If there's a firewall between you and the remote machine that allows an ssh connection to the remote machine, AND the remote sshd is configured to allow port forwarding, AND the remote machine can make a connection to the port on the mail machine, then you can forward connections to an arbitrary port on localhost to the remote mail machine via the remote ssh machine. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287163 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk __/\____/\_____/\____/|_____________________________________ flatline To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
