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.

perlbal::plugin::xffextras

Perlbal::Plugin::XFFExtras(3pm) 			User Contributed Perl Documentation			   Perlbal::Plugin::XFFExtras(3pm)

NAME

       Perlbal::Plugin::XFFExtras - Perlbal plugin that can optionally add an X-Forwarded-Port and/or X-Forwarded-Proto header to reverse proxied
       requests.

SYNOPSIS

	   # in perlbal.conf

	   LOAD XFFExtra

	   CREATE POOL web
	       POOL web ADD 10.0.0.1:80

	   CREATE SERVICE proxy
	       SET role 		       = reverse_proxy
	       SET listen		       = 0.0.0.0:80
	       SET pool 		       = web

	       SET plugins	       = XFFExtras

	       SET send_backend_port   = yes
	       SET send_backend_proto  = yes
	   ENABLE proxy

DESCRIPTION

       This plugin adds optional headers to be sent to backend servers in reverse proxy mode.

HEADERS

       o   X-Forwarded-Port

	   This header will contain an integer value indicating the port that the peer connected to.  This will correspond to the port number
	   specified on the listen line of the perlbal service that initially handled the connection.

       o   X-Forwarded-Proto

	   This header will contain a string indicating the protocol the client connected to perlbal via. Currently this will be either 'http' or
	   'https'.
