Hello, proxychains is a great aid for pure souls behind proxy, but it forwards all traffic through a proxy, this is often unacceptable. On proxychains sourceforge forum: http://sourceforge.net/projects/proxychains/forums/forum/644747/topic/1718334 patch is available to fix this: http://www.ece.auckland.ac.nz/~wsun013/proxychains/proxychains_exclude-3.1.patch It would be great to see it in portage. I tested it on my local overlay, it works OK. The only thing should be kept in mind: localnets should be added at the end of config file (or at least in [ProxyList] section.
I've added a snapshot release to the tree that includes localnet exclude support.
