Forum: Ruby Binding a specific IP address for Net::HTTP

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?

Did anyone find a resolution to this question? Rich

I've completely lost the context on this. What's the original question?

The ability to set the outing IP address on a HTTP request, if you're 
working on a server that have multiple network interfaces.

This functionality has been introduced and is described here, 
http://www.ruby-forum.com/topic/4403034.

Looks like it will be in version 2.0.0 from the bug report. If you
need it now, you can probably snag the patches.
