A simple HTTP and SOCKS proxy based on combining the following two go libraries:
- go-socks5 - https://github.com/armon/go-socks5
- goproxy - https://github.com/elazarl/goproxy
This application just runs the two proxies in the same process with command line flags to controll them.
$ ./http-socks-proxy -h
Usage of ./http-socks-proxy:
-hhost string
The host/ip on which the HTTP proxy listens for connections (default "127.0.0.1")
-hport int
The port on which the HTTP proxy listens for connections (default 2223)
-shost string
The host/ip on which the SOCKS proxy listens for connections (default "127.0.0.1")
-sport int
The port on which the SOCKS proxy listens for connections (default 2222)
-verbose
If verbose logging should be done
This can be used to access services running behind a firewall through a reverse SSH tunnel. E.g.
Computer A is behind a firewall. Start the proxy on Computer A then ssh from Computer A to Computer B and configure remote tunnels for the two ports:
ssh -R 2222:localhost:2222 -R 2223:localhost:2223 user@computerb
After this the HTTP and SOCKS proxies can be accessed on Computer B on port 2222 and 2223.
Now one can configure a web browser on Computer B to use the SOCKS or HTTP proxy and access resources only accessable from Computer A.
Edit ~/.subversion/servers and set the http-proxy-host and http-proxy-port configuration parameters in the 'global' section:
http-proxy-host = 127.0.0.1
http-proxy-port = 2223
$ ANT_OPTS="-Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=2223" ant
Cross-compile for windows using the following command:
$ GOOS=windows GOARCH=386 go build -o http-socks-proxy.exe main.go
