ssh alias, ssh with ease

Managing multiple servers can be tedious a lot of times; specially remembering the IPs and the ports for each and every single server.

Let's say your server IP is, you use port 500 and you use the username is root.
You will be normally using something like that:

$ ssh root@ -p 500

Today we will be discussing 3 different ways to make it easier.

1. Shell aliases

You can just create an alias for that by adding this line to your .bashrc

alias my_server="ssh root@ -p 500"

and now you can call it like this:

$ my_server

Now let's analyze this method.

The only advantage of this method is that you add one line and it works.

On the other hand this method offers no flexibility so you can't just use my_server -i ~/.ssh/keys/work.key and you can also conflict with other commands' names; for example add alias mysql="ssh root@ -p 500" as your mysql remote server alias.

2. SSH config file

Open ~/.ssh/config in your favorite editor and let's start.
To achieve the same results of the previous method we must add

  Host my_server
    User root
    Port 500

now save and then type this in your terminal

$ ssh my_server

This method allows a lot of flexibility as you can type ssh my_server -i ~/.ssh/keys/work.key or use any of the options that ssh already provides.
The whole problem is that you will need to maintain this file yourself adding each and every server to it (this needs a one-liner).

3. sshez

This is a method that will maintain your ssh config file with simple commands

sshez my_server root@ -p 500

and now you can

ssh my_server

you can install sshez by

$ gem install sshez

The only problem that it is currently dependent on ruby which is too much for just a CLT, but there will be a python clone very soon.
