Full Discussion: Setting X-Forwarded-For In C
Top Forums Programming Setting X-Forwarded-For In C Post 302980149 by Azrael on Wednesday 24th of August 2016 01:07:49 PM

It seems that tinyproxy would allow for changing the X-Forwarded-For header. However, it seemed that would stop other proxies from being used. Say someone was to use proxychains to spoof the original ip of a C program running through another proxy running on port 10000, a connection would need to be made to port 10000 after hitting 8888 or whatever port tinyport is running on.

I tried finding ways for spoofing X-Forwarded-For within proxychains itself before posting here, but came up empty handed with this as well. Would you know of a good way to pass tinyproxy traffic to proxychains, another port, or proxy?

EDIT: Forgot to mention, I do have wget and know how to use X-Forwared-For with Curl already. Looking for others ways to do this with C binaries that don't use these utilities though.

NAME
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 (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: ./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 targethost.com in this example it will run telnet through proxy(or chained proxies) specified by proxychains.conf COPYING
