proxychains4 - redirect connections through proxy servers

proxychains4 --help
proxychains4 [ -f configfile.conf ] <program>

This program forces any tcp connection made by any given tcp client to follow through proxy (or proxy chain). It is a kind of proxifier.

It acts like sockscap / premeo / eborder driver (intercepts TCP calls).

This version (v4) supports SOCKS4, SOCKS5 and HTTP CONNECT proxy servers. Auth-types: socks - "user/pass" , http - "basic".

1)
When the only way to get "outside" from your LAN is through proxy server.
2)
When you are behind restrictive firewall which filters outgoing connections to some ports.
3)
When you want to use two (or more) proxies in chain:
like: your_host <--> proxy1 <--> proxy2 <--> target_host
4)
When you want to "proxify" some programs with no proxy support built-in (like telnet).
5)
When you don't want to pay for eBorder / premeo socks driver :)

•
This program can mix different proxy types in the same chain. For instance:

your_host <-->socks5 <--> http <--> socks4 <--> http <--> target_host

•
Different chaining options are supported. For instance:

  • take random proxy from the list
  • chain proxies in exact order
  • chain proxies in dynamic order (smart exclude dead proxies from chain)

•
You can use it with any TCP client application, even network scanners. Yes, yes - you can make portscan via proxy (or chained proxies) for example with Nmap scanner by fyodor (www.insecure.org/nmap).

proxychains nmap -sT -PO -p 80 -iR (find some webservers through proxy)

NOTE: to run suid/sgid programs(like ssh) through proxychains you have to be root

proxychains looks for config file in following order:

./proxychains.conf
$(HOME)/.proxychains/proxychains.conf
/etc/proxychains.conf

More information is provided in /etc/proxychains.conf file.

proxychains telnet targethost.com

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

proxychains -f /etc/proxychains-other.conf telnet targethost2.com

In this example, it will use a different configuration file as specified to connect to targethost2.com host.
