All about proxies? Ubuntu 15.10


Recommended Posts

I wanted to proxify firefox on Ubuntu 15 I tried a couple of different methods. I remember it used to be just pop open firefox and manually enter the proxy IP and port in the network preferences. But it just doesn't work. I tried editing /etc/environment but no dice.

Is there is a prefered method?

Which configuration files or whatnot do I have to edit?

It actually is just that.

Preferences -> Advanced -> Network (tab) -> Settings... (button) -> Manual proxy configuration (radio button)

Fill in the various fields and you're done. Works instantly. Check out the traffic with Wireshark if you think things aren't working as they should.

When you tell your browser to use a proxy, it should only use the DNS to get the IP of the proxy server. All DNS lookups beyond that are (should be) done by the proxy server.

export http_proxy=http://5.6.7.8:1234

export https_proxy=http://5.6.7.8:1234 (not a typo - proxy url is http here too)

Alternatively use something like proxytunnel that takes traffic from localhost port X and route it to remote machine port Y via the proxy.

Also, one of my favorite tools would be proxychains

With a proper config and a uptodate socks proxy list you can run tools from the console like this...

Proxychains wget -O /dev/null 'http//place,com'

Proxychains my_socket_app

Proxychains telnet 66.66.66.66 23

Proxychains hydra -w 500_bad_pass.txt -p 22 hak5.org

Proxychains ping hak5

I have also wrote a script to populate the config with hundreds of working. Proxy's

Cool.

Is there a way to check if proxychains is working properly?

Also would be so as to post your config script?

the thing I love most about Ruby is irb... ill start up a interactive ruby shell and free hand some little hacky automation scripts like scrapping all the proxy's from a website... if its useful enough I may copy over to a text editor and add more useful fuctions...

if you were to look at the page source of any online proxy list you will find its scrambled up in a way that prevents people like me from automating this process... witch makes this little script a lot of fun to make.
