DD-WRT Firmware: The BasicsĭD-WRT is short for, well, nothing exactly. By the end of this article, you’ll know everything you need to about this type of firmware, including whether it’s a solution that you should be interested in or not. If you’re looking for answers about DD-WRT, then you’re in luck. So, what is DD-WRT firmware? Should you even care? You might know it has something to do with Internet routers and that it can be important if you want to use a VPN router.

SSH operates just as telnet with a user/password combination or on a Public/Private key infastructure. Unless changed, everything SSH operates on port 22. It can also be used for creating secure tunnels, somewhat akin to Virtual Private Networks, and for use as a network file system (Sshfs). SSH, or Secure Shell, is an encrypted protocol and associated program intended to replace telnet.
