![]() The basic idea to get this working is that we make one initial SSH connection to our home machine. On the router, port forwarding is enabled for SSH service to at least one of these machines.One/more Linux/Windows machine(s) to which direct SSH access is required.Home router’s internet accessible IP address or dynamic DNS (DDNS) address.Remote machine with Putty installed in it.But now I found a cooler way to get SSH access to all my machines at home without setting up port forwarding or remembering any port numbers and most importantly, I can address my home machines with local subnet IP address, no matter wherever I connect from the internet. It was also difficult to remember port number forwarded for a particular machine. It was a tedious process of enabling port forwarding and then disabling it after use. Previously, when I needed SSH access to these machines I used to setup port forwarding on my router to each of these machines. I have multiple Linux machines at my home. ![]() This means you won’t be able to get any SSH traffic over them, only actual HTTPS traffic.Create your own Virtual Private Network for SSH with Putty You can also try to be clever and use a less conspicuous port such as 443, but these are often subject to protocol detection on a firewall. After this restart sshd: systemctl restart rvice To do this (on 99% of Linux installations at least) open a CLI window and edit the /etc/ssh/sshd_config config file, add following lines: Port 22Ĭhange the port 10022 to any port you find to be open. Often corporate networks don’t allow port 22 going out, so you can change the config on your server to listen on a different port. Go to one of the million “what is my IP?” websites, it should show the IP from your server. In Firefox:ĭon’t forget to change the 8080 if you changed it in the previous step. Now go to your browser and change the proxy settings to use the SOCKS proxy. Saving the session is useful so you don’t have to do this every time you open up PuTTY. After this step, go back to Session and do the following: Instead of 8080 you can type in any local port, but higher port numbers (>1023) are required as the lower ports require administrative access. Navigate to Connection -> SSH -> Tunnels and do the following: If you get a warning about a private key or password prompt you have everything you need to setup a SOCKS tunnel. To test this, you’ll need to run PuTTY and see if you can open a SSH session to your server, use following settings: In corporate environments typically internet connectivity is impossible except from the corporate proxy to the outside. This is often deployed on corporate devices. If you do not get an error: great! If Applocker prevents you from running it, you might get stuck here. To check if you can run PuTTY, simply download “putty.exe” from the official PuTTY download page ( direct link to putty.exe) and run it. A server with shell access (SSH) enabled. ![]() ![]() Connectivity to the internet that is not inspected by any “smart” devices.Whether or not you can use a SOCKS proxy is highly dependent on your environment: is this a home PC behind a simple router, a work computer behind the corporate firewall or your school issued laptop on a public WiFi? There are three basic things you need: Besides the obvious use-cases, this can often mean a significant impact on your browsing speed as it allows your traffic to exit from a different geographical location. ![]() Using a SOCKS proxy allows you to encrypt all your web traffic between your machine and the proxy server, making it impossible for any local devices to inspect your traffic. ![]()
