3 | # oe-git-proxy is a simple tool to be via GIT_PROXY_COMMAND. It uses socat | ||
4 | # to make SOCKS5 or HTTPS proxy connections. It uses ALL_PROXY to determine the | ||
5 | # proxy server, protocol, and port. It uses NO_PROXY to skip using the proxy for | ||
6 | # a comma delimited list of hosts, host globs (*.example.com), IPs, or CIDR | ||
7 | # masks (192.168.1.0/24). It is known to work with both bash and dash shells. | ||
8 | # | ||
9 | # Example ALL_PROXY values: | ||
10 | # ALL_PROXY=socks://socks.example.com:1080 | ||
11 | # ALL_PROXY=https://proxy.example.com:8080 | ||
