ProxyChains - redirect connections through proxy servers SYNTAX
proxychains <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 (2.0) 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 dont want to pay for eBorder / premeo socks driver :) Some cool features: * This program can mix different proxy types in the same chain like: your_host <-->socks5 <--> http <--> socks4 <--> http <--> target_host * Different chaining options supported like: take random proxy from the list. or : chain proxies in exact order or : 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 ( 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: ./proxychains.conf $(HOME)/.proxychains/proxychains.conf /etc/proxychains.conf see more in /etc/proxychains.conf EXAMPLES
To run this program the standard way type: proxychains telnet in this example it will run telnet through proxy(or chained proxies) specified by proxychains.conf COPYING

CURLOPT_PROXY(3)					     curl_easy_setopt options						  CURLOPT_PROXY(3)

CURLOPT_PROXY - set proxy to use SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY, char *proxy); DESCRIPTION
Set the proxy to use for the upcoming request. The parameter should be a char * to a zero terminated string holding the host name or dotted numerical IP address. A numerical IPv6 address must be written within [brackets]. To specify port number in this string, append :[port] to the end of the host name. The proxy's port number may optionally be specified with the separate option CURLOPT_PROXYPORT(3). If not specified, libcurl will default to using port 1080 for proxies. The proxy string may be prefixed with [scheme]:// to specify which kind of proxy is used. http:// HTTP Proxy. Default when no scheme or proxy type is specified. https:// HTTPS Proxy. (Added in 7.52.0 for OpenSSL, GnuTLS and NSS) socks4:// SOCKS4 Proxy. socks4a:// SOCKS4a Proxy. Proxy resolves URL hostname. socks5:// SOCKS5 Proxy. socks5h:// SOCKS5 Proxy. Proxy resolves URL hostname. Without a scheme prefix, CURLOPT_PROXYTYPE(3) can be used to specify which kind of proxy the string identifies. When you tell the library to use a HTTP proxy, libcurl will transparently convert operations to HTTP even if you specify an FTP URL etc. This may have an impact on what other features of the library you can use, such as CURLOPT_QUOTE(3) and similar FTP specifics that don't work unless you tunnel through the HTTP proxy. Such tunneling is activated with CURLOPT_HTTPPROXYTUNNEL(3). libcurl respects the environment variables http_proxy, ftp_proxy, all_proxy etc, if any of those are set. The CURLOPT_PROXY(3) option does however override any possibly set environment variables. Setting the proxy string to "" (an empty string) will explicitly disable the use of a proxy, even if there is an environment variable set for it. A proxy host string can also include protocol scheme (http://) and embedded user + password. The application does not have to keep the string around after setting this option. DEFAULT
Default is NULL, meaning no proxy is used. When you set a host name to use, do not assume that there's any particular single port number used widely for proxies. Specify it! PROTOCOLS
All except file://. Note that some protocols don't do very well over proxy. EXAMPLE
Since 7.14.1 the proxy environment variable names can include the protocol scheme. Since 7.21.7 the proxy string supports the socks protocols as "schemes". Since 7.50.2, unsupported schemes in proxy strings cause libcurl to return error. RETURN VALUE
Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space. SEE ALSO
