@nnposter -- great catch about SOCKS5. Yeah, if you could add that, it would be great. The Ncat man page is generated from ncat/docs/ncat.xml. Sometimes installing DocBook and such is a pain, so if you just update ncat.xml, we can regenerate the HTML and Nroff versions later. Cheers!
Sure. Changes are actually needed in both ncat.xml and ncatguide.xml. I have already put the patch together over the last weekend and I plan to commit it sometime next week (together with my other outstanding patches).
