------

ProxyChains is a UNIX program, that hooks network-related libc functions in DYNAMICALLY LINKED programs via a preloaded DLL (dlsym(), LD_PRELOAD) and redirects the connections through SOCKS4a/5 or HTTP proxies. It supports TCP only (no UDP/ICMP etc). The way it works is basically a HACK; so it is possible that it doesn't work with your program, especially when it's a script, or starts numerous processes like background daemons or uses dlopen() to load "modules" (bug in glibc dynlinker). It should work with simple compiled (C/C++) dynamically linked programs though.

If your program doesn't work with proxychains, consider using an iptables based solution instead; this is much more robust.

Supported Platforms: Linux, BSD, Mac.

*********** ATTENTION ***********

  this program can be used to circumvent censorship.
  doing so can be VERY DANGEROUS in certain countries.

  ALWAYS MAKE SURE THAT PROXYCHAINS WORKS AS EXPECTED
  BEFORE USING IT FOR ANYTHING SERIOUS.

  this involves both the program and the proxy that you're going to
  use.

  for example, you can connect to some "what is my ip" service
  like ifconfig.me to make sure that it's not using your real ip.

  ONLY USE PROXYCHAINS IF YOU KNOW WHAT YOU'RE DOING.

  THE AUTHORS AND MAINTAINERS OF PROXYCHAINS DO NOT TAKE ANY 
  RESPONSIBILITY FOR ANY ABUSE OR MISUSE OF THIS SOFTWARE AND 
  THE RESULTING CONSEQUENCES.

When to use it ?
1) When the only way to get "outside" from your LAN is through proxy server.
2) To get out from behind restrictive firewall which filters outgoing ports.
3) To use two (or more) proxies in chain:
	like: your_host <--> proxy1 <--> proxy2 <--> target_host
4) To "proxify" some program with no proxy support built-in (like telnet)
5) Access intranet from outside via proxy.
6) To use DNS behind proxy.
7) To access hidden tor onion services.

Some cool features:

* This program can mix different proxy types in the same chain
	like: your_host <-->socks5 <--> http <--> socks4 <--> target_host
* Different chaining options supported
	random order from the list ( user defined length of chain ).
	exact order  (as they appear in the list )
	dynamic order (smart exclude dead proxies from chain)
* You can use it with most TCP client applications, possibly even network 
	scanners, as long as they use standard libc functionality.
	pcap based scanning does not work.
* You can use it with servers, like squid, sendmail, or whatever.
* DNS resolving through proxy.


Configuration:
--------------

proxychains looks for config file in following order:
1)	file listed in environment variable PROXYCHAINS_CONF_FILE or
	provided as a -f argument to proxychains script or binary.
2)	./proxychains.conf
3)	$(HOME)/.proxychains/proxychains.conf
4)	$(sysconfdir)/proxychains.conf  **

** usually /etc/proxychains.conf

Usage Example:

	$ proxychains4 telnet targethost.com

in this example it will run telnet through proxy(or chained proxies)
specified by proxychains.conf
