Example
If you have set a long passphrase and do not wish to keep entering it every time you want to connect to the server, you can use SSH-Agent to store your passphrase while you are logged in on your computer.
Start the ssh-agent in the background:
eval "$(ssh-agent -s)"
# Agent pid 59566
And add your key to the ssh-agent, you will be prompted to enter your passphrase:
ssh-add ~/.ssh/matrix.ac
# Enter passphrase for /home/osaka/.ssh/matrix.ac:
# Identity added: /home/osaka/.ssh/matrix.ac (/home/osaka/.ssh/matrix.ac)
Done. Now connect with ssh [email protected] and you should not have to enter your passphrase. You can extend this by using programs like gnome-keyring/seahorse, keychain and other key managers.
