In general, you're out of luck. Pretty much every service uses IP addressing only; thus, unless you have sufficient routable IP addresses (ie, your ISP is providing you with a subnet) then you simply can't do this. The major exception is HTTP (and the various things that layer on top of it) which carries the target hostname as part of the protocol. Unfortunately, HTTPS leaves you back at square one since it uses SSL directly rather than via some form of STARTTLS negotiation that might be able to send the desired hostname. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ Bolstered by my success with vi, I proceeded to learn C with 'learn c'. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
