Proxytunnel is a program that connects stdin and stdout to a server somewhere in the Internet through an industry standard HTTPS proxy. It's mostly used as a backend for OpenSSH's ProxyCommand, and as a proxy backend for Putty. It can also be used for other proxy-traversing purposes. License: GNU General Public License (GPL) Changes:
