sending IP pkgs form user space on a specific interface?

sending IP pkgs form user space on a specific interface?

[Joakim Tjernlund]

Is there a way to specify what I/F a IP pkg should be sent
out on?

I have multiple ppp I/Fs with the same local and remote address
and I need to specify what interface to send OSPF protocol
messages to.

Check out SO_BINDTODEVICE.

Thanks, can do setsockopt(s, SOL_SOCKET, SO_BINDTODEVICE, ..) for
each I/Fs I need tx pkgs over?
How do I unbind to any I/F?

If possible, I would like to specify the I/F in the pkg overhead.

Man-pages and google should find those answers.
You could put my name in your search as well, if you want..I know I've
posted sample code in the past to some mailing list or another.

Thanks,
