on linux vps.

git clone https://github.com/qsantos/socks socks-by-qsantos

cd socks-by-qsantos

./socks -h

显示：

Usage: ./socks mode [OPTIONS] [-f file|proxy1 [proxy2...]]

The proxies are chained to strenghten privacy

mode:

  cat    c  stdin and stdout are piped through the proxy chain

  serve  s  starts a server sending data through the chain

  check  k  check the proxy chain

OPTIONS:

  --continue  -c  ignore any unreachable proxy and test the next one

  --verbose   -v  show more information

proxies: the list of proxies can be given as the arguments of the command line

         or as a file (one per line) ; if no option is given, stdin is assumed

         a proxy is of the form

host:port[:type[:user:pass]]

  host   is an IPv4, IPv6 (not after a SOCKS4 proxy) or domain address

  port   is the port where the server listens for connections

  type   optionnal, can be either 'socks4' or 'socks5'

  user   optionnal, used for username/password authentication

  pass   optionnal, used for username/password authentication

于是，

./socks serve host 127.0.0.1 port 3267 user myusername pass mypassword

可用作各类tunnel程序的后端程序。
