SSH keys

Generate SSH key

• Basic SSH key: ssh-keygen -t rsa -b 4096
• SSH key for Github ssh-keygen -t rsa -b 4096 -C "your@email.com"

Copy to server

ssh-copy-id user@server

SSH Agent

To set up SSH agent to avoid retyping passwords, you can do two things:

1. Add an ssh config file (will be absent by default)

   vi ~/.ssh/config

   Host [hostname]
   User [username]
   IdentityFile ~/.ssh/[key]

2. Add the key when starting bash:

   echo "ssh-add ~/.ssh/id_rsa &>/dev/null" >> .bashrc
