I have a multihomed Windows 2003 server. Is there a way to specify the source IP address to use with the telnet client?

    You could add a static route to the host you are connecting to.

    For example...

    You connect to 10.10.6.5

    Interface 1: 192.168.1.50/32
    Interface 2: 192.168.2.50/32
    Default gateway: 192.168.1.1
    Static route for 192.168.2.0/24 to 192.168.2.1

    If you want to connect to 10.10.6.5 via 192.168.2.1, you add this static route:

    route add 10.10.6.5 mask 255.255.255.255 192.168.2.52

  2. on linux, it's 

    telnet -b source-ip dest-ip

    to "bind" to a different interface

  3. You could use ncat:

    ncat -s 10.0.50.3 -t 10.1.1.1
