SSh Hosts and Private Keys
You work with many remote networks on a daily basis as a server administrator. Throughout your job, you may need to SSH into systems several times. You can access several remote Linux servers with a password, and you can even access them with a private key. As a result, managing all of them might be more typical.
This article will show you the best way to manage SSH Hosts and Private Keys.

Syntax of the Configuration File:
Multiple ssh hosts may be defined in the /.ssh/config

to edit the configuration file.

user root, port 22,
and password access. In the configuration file, add the following content.
2. Configure a second SSH host
On default port 22,
our second host server (php-web2)
is accessible via ssh key-pair with user root. In the configuration file, add the following content.
Now try SSH with the command below.
3. Add a third SSH host server
Our third ssh host server (php-db1)
is accessible via key-pair with user ubuntu on port 2222.
In the configuration file, add the following content.
Now try SSH with the command below.
4. Use SSH to set up forwarding
