# proxychains4(1)

redirect connections through proxy servers

## NAME

proxychains4 - redirect connections through proxy servers

## SYNOPSIS

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

## DESCRIPTION

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".

### When to use it?

- 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 :)

### Some cool features:

- •

  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

## FILES

proxychains looks for config file in following order:

- file listed in environment variable **PROXYCHAINS\_CONF\_FILE** or provided as a *-f* argument to proxychains script or binary.

  - *./proxychains.conf*

  - *$(HOME)/.proxychains/proxychains.conf*

  - */etc/proxychains.conf*

  - */etc/proxychains4.conf*

  More information is provided in */etc/proxychains4.conf* file.

## EXAMPLES

- To run this program the standard way type:

  ```
  proxychains telnet targethost.com
  ```

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

- To run this program with custom configuration file:

  ```
  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.
