-The latest version of PuTTY can always be obtained directly from the owner's official web page. Visit the [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTY Download Page] and choose [http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe putty.exe] from the file list. When you download it, I suggest that you save it to your desktop, or somewhere where it will not get accidentally deleted. PuTTY.exe is a standalone executable, meaning there is no installation involved. All profile data is saved to the Windows Registry, meaning that if you use a backup solution such as [[Symantec Ghost]] you will have to recreate your profiles.+The latest version of PuTTY can always be obtained directly from the owner's official web page.

 PuTTY has support for saved sessions for use convenience. Generally you enter your information and configure your session as you wish, type a named in the "Saved Sessions" box, and click Save. It will add the session to the list. If you would like to edit your session settings later, simply click the session, click Load, make the appropriate changes, and click Save.

 This screen is basically informing you that you do not have this SSH Server's Encryption Key cached. This usually only happens when you've never connected to that SSH server before. If you've been connecting to the same server for a while, and you suddenly get this notification, either your host has changed its SSH server, or a different server may be impersonating your old SSH server. If this is your first time connecting to the server, click Yes to accept the Key. After you accept the key, you will not be prompted to accept it unless it changes. This screen is basically informing you that you do not have this SSH Server's Encryption Key cached.

 You can setup PuTTY in a way that it acts like a SOCKS server, directing all data through your server. For instance, say you wanted to Proxy all your web browsing through your server. All you have to do is setup PuTTY to create a SOCKS Proxy (and tunnel), direct your browser to use 127.0.0.1 (and a port we'll specify later) as the SOCKS5 server. Any websites you visit will appear as if they are being viewed from your server. If you go to [http://www.whatismyip.com/ WhatIsMyIP] it will show your server's IP address, instead of your own. You can setup PuTTY in a way that it acts like a SOCKS server, directing all data through your server.

-All data between your computer and your server will be encrypted, though after it exits your server you rely on the protocol your browser was using (HTTP/HTTPS/etc). This can be beneficial when you are connected to an insecure network (such as Public WiFi). This can also be used to circumvent content filtering on various networks (such as at work or school), though it is most likely against the network's [[AUP]]. Please note that you can "tunnel" any program through your server assuming that the program has support for SOCKS Proxification.+All data between your computer and your server will be encrypted, though after it exits your server you rely on the protocol your browser was using (HTTP/HTTPS/etc).

 To add the tunnel, load a configuration profile, then go to the Tunnel which is under SSH, which is under Connection. Choose a source port, this will be simply for your use, I suggest choosing something 1000+. In this example I use 12345.

 From here we are done setting up the tunnel. I suggest you save the profile so you can easily start your tunnel. Please note that the tunnel is not active until you are FULLY LOGGED IN to your SSH server. You may tell any program to use "Hostname: 127.0.0.1 Port: 12345" (change 12345 to your port) as a SOCKS server and all data will go through your server! From here we are done setting up the tunnel.
