vi /etc/ssh/ssh_config

Host 192.168.0.7 test
    HostName 192.168.0.7
    IdentityFile ~/.ssh/realname_rsa
    User remoteusername
    Port xxxx



Host myother realname2.example.org
    HostName realname2.example.org
    IdentityFile ~/.ssh/realname2_rsa
    User remoteusername

Tips

• check with hostnamewhere are you

Connect to

• Make a .ssh directory in your non-root user home directory. Put the key in a file called ~/.ssh/authorized keys. Do the same for every user user. http://serverfault.com/questions/555516/setup-public-key-authorized-ssh-for-non-root-users
• Otherwise you get Server refused our key
• mkdir -p /home/limited/.ssh
• chown -R limited:limited /home/limited/.ssh
• ssh-keygen -t rsa -b 4096

Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): /home/limited/.ssh/id_rsa

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile      .ssh/authorized_keys
