LWP::UserAgent and non-default outgoing IP

[Tomek]

Hello!
My box on which Perl runs has several IPs, let's say that:

192.168.0.1 is the first IP and the default one,
192.168.0.5 is the last IP

How to force LWP::UserAgent to connect to remote hosts from IP 192.168.0.3
? I couldn't find it in the manual of LWP

Now, it always connects from the first and default IP: 192.168.0.1 How
to bind other outgoing address?

Regards, Tomasz Kraus

You can set the variable @LWP:rotocol::http::EXTRA_SOCK_OPTS to some
extra options to pass to every socket created for http communication. I
can't see with a quick look how to do the same for https/ftp, but this
may be enough for your problem.

The secret is in the source code of LWP:rotocol::http. See the
@EXTRA_SOCK_OPTS variable defined there, and note how it is used. I'm not
sure why it's not documented... maybe it's not well tested yet. But it works.
