Binding a specific IP address for Net::HTTP

Stephan Pilot

I hope I'm not asking a question that has been answered
many times before: I can't find any information on
how to bind a specific IP address (on a server with
multiple addresses) so that a post from a Net::HTTP
object is sent with that specific IP address.

Many thanks for your help!

AFAIK the only way to do this (absent the use of platform-specific, non-Ruby
properties) is to open the server using the desired address. It is not
possible to pick and choose addresses at runtime from the server side
during a server-client transaction.

Or did you mean "port" when you said "address"?

I was referring to an option available with the wget utility on Linux
boxes ( e.g. --bind-address=10.0.0.1 ), since the http server I am
trying to contact only allows connections from a specific IP address and
I don't know how the ruby Net::HTTP selects its own IP address when
there
are several to choose from on the machine running ruby. I guess I will
have
to write a very basic http client using "handcrafted" sockets then?
