Connecting through a proxy server (without LWP)

batkins has asked for the wisdom of the Perl Monks concerning the following question:

I have a Perl script that needs to connect to a server on port 80. Unfortunately, the network I have to run this on requires usage of an NTLM proxy for all outgoing connections. I'm using port 80 because as far as I can tell, all other ports have been blocked, and the server to which I'm connecting accepts connections on all ports.

I had trouble getting Authen::NTLM to work, so I downloaded NTLMAPS from SourceForge, gave it my credentials, and pointed it at my proxy. I tried setting my proxy to localhost in Opera and it successfully tunneled pages (Opera never worked before because it doesn't understand NTLM).

But the problem is that I'm not sure how to go about getting through the local proxy set up by NTLMAPS. I can't use LWP for this (I'm not retrieving Web data). So how do I tunnel a regular Perl socket through an anonymous proxy?

Any help would be appreciated.

TIA,
Bill

Anonymous proxies are, well, anonymous. They transparently grab connections without programs being aware of it. That said, look at IO::Socket::Socks and Net::HTTPTunnel. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer Note: All code is untested, unless otherwise stated	[reply]
