What is SSH?

  • Secure Shell: What is a shell?
    • CLI for controlling or running commands on a computer
    • Mouse and Desktop actions can translate into commands
    • Comparable to remote desktop for windows
    • Command line driven
  • It is pretty secure, atleast SSH2 is.

How can I benefit from SSH-ness?

  • The more you are familiar with command line the better. But not a MUST!
  • SCP – cp file from point a to point b
  • Tunnelling – forward ports from comp to server.
    • tunneling mysql is awesome!
  • SFTP – popular amongst ftp clients
  • Mounting Drives – Mount a directory on your computer that only exists on the server
  • VPN – openSSH allows for a VPN over a ssh connection
  • RSYNC – program used for sync directories from one machine to another
  • Backups – Migrating from one hosting to another? Backings up zip files from one server to another?

How do I use it?

  • Windows
    • putty
    • SecureCRT
    • Arlo: git bash
    • cygwin – heard of it, give it a try.
  • Mac OSx/Linux
    • openssh. should come out of the box
  • Server must have it installed and running
    • most shared hosting do
  • Access with username and password
  • Public keys are prefered
    • locally run: ssh-keygen (press enter all the way through)
    • copy contents of: ~/.ssh/id_rsa.pub
    • paste content on server: ~/.ssh/authorized_keys
    • ssh-copy-id ~/.ssh/id_rsa.pub username@hostname
