Genarating and sharing public key

How to create a new public key for ssh and add it to the remote machine.

generate key:

ssh-keygen -t rsa

Append it to the server:

cat ~/.ssh/id_rsa.pub | ssh user@server "cat >> ~/.ssh/authorized_keys"

Copy a file to the remote machine:

scp ~/path/to/file user@server:/path/on/server

Copy a file from the remote machine:

scp user@server:/path/to/file ~/path/on/local

SSH Config

Creating a ~/.ssh/config file. Having aliases for SSH is a dream.

    Host somealias
        HostName example.com
        Port 2222
        User someuser
        IdentityFile  ~/.ssh/id_example
        IdentitiesOnly yes

    Host anotheralias
        HostName 192.168.33.10
        User anotheruser
        PubkeyAuthentication no

    How aws
        HostName some.address.ec2.aws.com
        User awsuser
        IdentityFile  ~/.ssh/aws_identity.pem
        IdentitiesOnly yes

Usage: ssh somealias

  • HostName - The server host (domain or ipaddress)
  • Port - The port to use when connecting
  • User - The username to log in with
  • IdentityFile - The SSH key identity to use to log in with, if using SSH key access
  • IdentitiesOnly - "Yes" to specify only attempting to log in via SSH key
  • PubkeyAuthentication - "No" to specify you wish to bypass attempting SSH key authentication
