![]() Now all DNS requests will go through the SOCKS5 proxy rather than the local network. As were using SOCKS proxy, to test the connection, we need an app that can use it. ![]() Set the value to True (Right Click on the value in the column) You need to have SSH configured prior to making it work smoothly. Then you go to your locally installed Firefox (on the machine with putty) proxy settings. This will add local socks proxy listener, which will see the network from perspective of the server. If you want your DNS requests to go through the SOCKS5 proxy (yes you want this feature - trust me if you are going through all the trouble to create this encrypted tunnel), you need to do the following.ģ. To configure this, you can go in Putty to Connection->SSH->Tunnels, then add new one with source port like 8888, destination port empty, then Dynamic, Auto. DNS requests are requests that look up names like and turn them into IP addresses. ![]() Using the ssh SOCKS5 proxy all of your info is passed through the tunnel except DNS requests. If your settings are right and it still is not working replace localhost with 127.0.0.1. Instead of that, one can send only the web traffic through the SSH tunnel and have the browser running locally. Note: Sometimes localhost can cause a problem. Next we need to put the settings into Firefox.įirefox> Edit> Preferences> Advanced tab> Network tab> Settings button. We are also adding the -C switch for compression. Ssh -D 9999 -C -D switch - Specifies a local “dynamic” application-level port forwarding. Put simply, FoxyProxy automates the manual process of editing Firefoxs Connection Settings dialog. This tutorial assumes you have an account on a remote machine you can ssh into. WHAT IS IT FoxyProxy is a Firefox extension which automatically switches an internet connection across one or more proxy servers based on URL patterns. ![]() The tunnel encrypts and sends the data to your remote machine then it is sent over the web to your destination. Especially when connecting via an untrusted network like a wifi hotspot or other public networks. Now, just open the new Windows shortcut to Google Chrome, and enjoy your web surfing!Īgain, remember that you always must open the SSH session we saved in Step 1 first in order to be able to use the SOCKS proxy we have just configured.A ssh tunnel for Firefox to a remote computer is good security measure. In this case, we can also create a Windows Shortcut on our Desktop to directly run a Google Chrome profile that uses our SSH Tunnel (but in this case, using something similar to the above command): Google Chrome shortcut E.g.: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -user-data-dir="%USERPROFILE%\proxy-profile" -proxy-server="socks5://localhost:8080" Thus, to have a separate instance of Google Chrome capable of using our SSH tunnel without interfering with other applications or configuration, we only need to provide the -user-data-dir argument and the -proxy-server argument. ssh -p 2034 -D 127.0.0.1:1080 rootvpsip The port on my VPS is 2034. Nevertheless, it is possible to set a differen SOCKS proxy at startup via a command-line argument. Sorry for the screenshot with UIs in Spanish! ?īonus Step 3b: Configure Chrome to use the SSH tunnel in a separate profileĪlthough Google Chrome also allows using different profiles, for its network configuration it relies on the Internet configuration of the system. Because of that, next, I will show you how to setup your (Windows) computer so that you can leave the tunnel preconfigured in such a way that can be opened in a few clicks when needed. In such a case, one very easy workaround is just to use an SSH connection to create a tunnel that will redirect your browser’s navigation info through it.Īlthough there are already quite a few tutorials on the net on how to do this, I’ve been asked too many times on how to do it that I prefer to keep my own tutorial for this. ssh -D9090 -N usermysshserver Then firefox has to be configured to use the ssh tunnel: open Preferences open Network Settings (scroll down in General tab) choose Manual proxy configuration in the SOCKS Host field, write localhost and in the Port field, write 9090 keep the SOCKS v5 button selected click OK Done. But VPN credentials are normally controlled by a central IT service that won’t be allowed to give permissions to somebody that is no longer part of the institution. To access that kind of remote private resources, you’d normally use a VPN connection. As a researcher that has been working in different institutions already, one of the most common issues I have faced when moving from one place to another is losing access to the network (and “private” resources) of my previous university and/or team. ![]()
