HTTP and SOCKS proxy

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

Use case

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.

Configure Subversion to use a HTTP proxy

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    

Configure Apache Ant to use a HTTP proxy

$ ANT_OPTS="-Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=2223" ant

Cross-compile for Windows

Cross-compile for windows using the following command:

$ GOOS=windows GOARCH=386 go build -o http-socks-proxy.exe main.go
