Example SSH Config Entry for personal accounts

ssh_config

# SSH_CONFIG example
# David Sanabria, 2017-01-24
#
# This is an example of a personal SSH config file. You need to add this
# file to the ssh root directory on your computer, which is typically found in your
# home directory (e.g. ~/.ssh/config). You can learn more from the command line by 
# typing "man ssh_config" from your terminal (*nix) or from my blog entry on this topic
# at http://bit.ly/2jX2GQr (Wordpress).
# 
# You can safely delete every line in this example gist that starts with the "#" comment
# character.
#
# Using this approach allows you to connect to your target server using the following
# simple command (you can use SFTP this way too!):
# 
#        EASY! -->   ssh dev-app-svr
#
# Rather than the harder way of of specifying everything on the command line
#
#        HARD! --> ssh -i ~/.ssh/king-julian-development king-julian@192.168.10.75
#
 
# The entry below will allow you to connect to your hypothetical application server in
# your development environment. This example assumes the following:
#    1. Your target server is 192.168.10.75
#    2. Your username on the server is "king-julian"
#    3. You have created an SSH keypair specifically for use in your development server
#       (always a good practice), and named the keypair "king-julian-development" (private)
#       and king-kulian-development.pub (public key)
#    4. You have already added the public key to the ~/.ssh/authorized_keys file on the target server.

# Example Host Entry

Host dev-app-svr
    # Target Server and port number
    Hostname 192.168.10.75
    Port 22
    
    # Your Credentials
    User king-julian
    IdentityFile ~/.ssh/king-julian-development
    
    # These commands make sure that your connection doesn't hang if you get
    # disconnected, and also keep sending traffic so that your server doesn't
    # think you're just an idle connection.
    
    ServerAliveInterval 30
    ServerAliveCountMax 3
    TCPKeepAlive yes
    

# Bonus for reading this far! Here is a command that will easily list all of your config entries
# in case you forget them:
#
#      grep ~/.ssh/config -e 'Host ' | awk '{print $2}'
