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](http://www.inet.no/dante/), but found it just to hard to just configure in a few minutes.
|
|
|
|
I'm a ruby programmer and I knew [Github](https://github.com) once released a small open-source proxy programm.
|
|
It's called [proxymachine](https://github.com/mojombo/proxymachine), made by [@mojombo](https://github.com/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:
|
|
|
|
~~~ruby
|
|
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](http://en.wikipedia.org/wiki/SOCKS#SOCKS4) Proxy up and running.
|
|
|
|
[@nerdsein](https://twitter.com/#!/nerdsein/status/120258441041297409) got another solution: [Mocks](http://sourceforge.net/projects/mocks/), "**M**y **O**wn so**CK**s **S**erver."
|
|
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"}
