What's up folks! Markiplier here, I will show you how to work with SSH for different systems. I don't have any expirience with Apple software but it should handle the same as Linux I will mention if Windows needs special attention.

SSH stands for Secure Shell. It's used most commonly for connecting to servers/computers. It was a replacement for Telnet, which is plaintext, while SSH uses stronk encryption. The most common SSH is OpenBSD's OpenSSH, but there are alternatives like Dropbear.

Everything written inside <brackets should be replaced, with them included> I will write $ if user can write a command and # if root/admin has to intervene

if you want to connect to a server, write in your shell
$ ssh <user>@<ip or domain>

There flags that you should know

• -p for port
• -i <your private key include key
• -v verbose, if you need more info on what is happening during connection and breaking it
• -R <server port>:localhost:<client port> port forwarding from server to client
• -L <client port>:localhost:<server port> port forwarding from client to server
• -N do not execute any commands, useful for port forwarding
• -f run ssh in background after auth, also useful for port forwarding

config

Host <yourname>
  Hostname <your IP/domain>
  User <your username>
  IdentityFile <path to private SSH key>
  Port <port opened for SSH>
