fast and simple proxy server
So you have this friend sitting somewhere else in the world and want to give him a simple proxy to access a geoip-protected site or something similar. But what tool to use?
When searching for a proxy I found dante, but found it just to hard to just configure in a few minutes.
I'm a ruby programmer and I knew Github once released a small open-source proxy programm. It's called proxymachine, made by @mojombo, one of the founders of github.
Get it with:
gem install proxymachine
and you're nearly done.
Pipe the following into a text file:
proxy do |data| next if data.size < 9 v, c, port, o1, o2, o3, o4, user = data.unpack("CCnC4a*") return { :close => "\x0\x5b\x0\x0\x0\x0\x0\x0" } if v != 4 or c != 1 next if ! idx = user.index("\x0") { :remote => "#{[o1,o2,o3,o4]*'.'}:#{port}", :reply => "\x0\x5a\x0\x0\x0\x0\x0\x0", :data => data[idx+9..-1] } end
and start it with
proxymachine -h 0.0.0.0 -p 1234 -c your_socks_config.rb
{:lang="text"}
Tada! You got your own SOCKS4 Proxy up and running.
@nerdsein got another solution: Mocks, "My Own soCKs Server." Download it over at Sourceforge, unpack it and compile the code with:
gcc -lnsl -o mocks child.c error.c misc.c socksd.c up_proxy.c
{:lang="text"}
You can configure a little bit more than with proxymachine, but you can stick with the default config for now:
PORT = 10080 MOCKS_ADDR = 0.0.0.0 LOG_FILE = mocks.log PID_FILE = mocks.pid BUFFER_SIZE = 65536 BACKLOG = 5 NEGOTIATION_TIMEOUT = 5 CONNECTION_IDLE_TIMEOUT = 300 BIND_TIMEOUT = 30 SHUTDOWN_TIMEOUT = 3 MAX_CONNECTIONS = 50 FILTER_POLICY = ALLOW
{:lang="text"}
See the README and the config file in the archive for comments on it. Then start it with:
src/mocks -c mocks.config start
{:lang="text"}
and kill it with:
src/mocks -c mocks.config shutdown
{:lang="text"}
Oh, and in case you have the possibility to just ssh to the server, you can start up a SOCKS proxy on this connection, too:
ssh -D1234 example.com
{:lang="text"}
