Summary: library to allow transparent SOCKS proxying
Version: 1.8
Release: 7.beta5.2
License: GPL
Group: Applications/Internet
URL: http://tsocks.sourceforge.net/
Description: tsocks is a library to allow transparent SOCKS proxying. It supports both SOCKS 4 and SOCKS 5 (only TCP).

tsocks is designed for use in machines which are firewalled from the internet. It avoids the need to recompile applications like lynx or telnet so they can use SOCKS to reach the internet. It behaves much like the SOCKSified TCP/IP stacks seen on other platforms.

### A wrapper script for the tsocks(8) transparant socksification library.
### Written by Dag Wieers <dag@wieers.com>.
###
### There are 3 modes of operandi:
###
###  * tsocks <program> <args ...>
###
###    This will socksify the current program only.
###    eg.
###         [user@host ~]# tsocks telnet www.foo.org
###
###  * tsocks [on|off]
###
###    This will socksify the current shell (and childs).
###    eg.
###         [user@host ~]# source /usr/bin/tsocks on
###         (user@host ~)# telnet www.foo.org
###         [user@host ~]# source /usr/bin/tsocks off
###
###  * tsocks
###
###    This will create a new socksified shell.
###    eg.
###         [user@host ~]# tsocks
###         (user@host ~)$ telnet www.foo.org
###         (user@host ~)$ exit
###         [user@host ~]#
