Go back to the “Session” option in the left panel.Where it says “Forwarded ports”, select “Dynamic”.This tells PuTTY to listen to data sent to it on port 8080 from the same computer putty is running on, and forward it to the remote server. Assuming you picked 8080 for the port, then enter “localhost:8080” (without quotes) as the destination.Enter the local port you want to use for the proxy connection in the “Source port” field.From the “Category” section on the left, scroll to “Connection” > “SSH” > “Tunnels”.For “Host Name” enter the domain name or IP address of the server that will act as the proxy.You’ll need a valid login (username and password, or SSH key) for an account on that server. You’ll also want the hostname or IP handy for the server you’ll SSH into to act as the proxy. To use PuTTY as a SOCKS proxy, make sure your computer has PuTTy installed. Follow these steps to set up PuTTY as a SOCKS proxy: This can make it much easier to use and configure, especially when you want to connect to a wider range of websites or services. Overall, PuTTy’s SOCKS proxy functionality builds upon basic SSH tunneling, offering the same benefits, but with additional flexibility. Due to the flexibility of SOCKS, this is possible without having to configure each application and network destination individually. This is helpful for secured access to a variety of networks and services that your server is able to reach that your computer cannot connect to, or if you simply want to encrypt your traffic. Once you’ve done this, any traffic sent through the proxy will be forwarded to the remote server, which will then route the traffic to its final destination for you. This allows you to set up SOCKS compatible applications like your web browser to use the locally available proxy port. Using PuTTy as a SOCKS proxy, by contrast, is similar to SSH tunneling in how it works, but uses the SOCKS proxy protocol to forward various kinds of traffic instead of rigidly forwarding traffic from one source to one destination. This allows you to use SSH encryption to access services hosted on the remote server, potentially bypassing firewalls and keeping your data secure in transmission. With basic SSH tunneling, it’s possible to forward network traffic from a local port on your computer to a specific port on a remote server. The basic form of SSH tunneling was covered in a previous article. Setting up a SOCKS proxy is a more advanced type of SSH tunneling. With a program like Proxifier, all running programs can be tunneled via a SOCKS Proxy, similar to using a VPN. This is useful for privacy or to bypass ISP restrictions. The proxy forwards this data for you, masking your IP address. Unlike an HTTP proxy which only works for websites, SOCKS can also be used for games, instant messenger, or other applications. SOCKS is a protocol for transporting arbitrary TCP data via a proxy server. How to configure your browser to use the socks proxy.Follow these steps to set up PuTTY as a SOCKS proxy:.How does this compare to SSH Tunneling?.
