How to chain proxy after Tor

Question

How can I use a proxy after Tor? Few sites that I use refuse connections from Tor due to abuse, and because of DDOS many sites behind cloudfare/akamai constantly ask me to do captcha every refresh. So is there a way to do this me -> Tor exit node -> my_proxy -> www ???

Answer 1

There are, probably thousands of combinations you might implement.

I'm trying to collect best Unix-like versions, if somebody know better, easiest, shortest way to setup proxy after Tor, you are welcome to complete my answer.

1) Read this article TransparentProxy and this IsolatingProxy, thereafter, you may start anything under transparently anonymized specific user. For example, start Firefox, go to settings -> connection settings, set your proxy for Firefox. Your Firefox will achieve target host by next chain:

localhost -> Transparent Port ( Tor ) -> Guard ( Tor ) -> Middle ( Tor ) -> 
-> Exit ( Tor ) -> Your Proxy -> Target Host

2) Another perfect tool is proxychains.

Dedicated OS: Linux and other Unices.

Configuration file /etc/proxychains.conf should be like:

strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app

# Make sense only if random_chain
chain_len = 2

# Proxy DNS requests - no leak for DNS data
proxy_dns 

[ProxyList]
# add proxy here ...
socks5         127.0.0.1 9050       # Tor socks5 
socks5         184.152.92.156:37071 # https://hidemyass.com/proxy-list/

Now you can launch any browser via proxychains:

$ proxychains firefox
