Before we start counting the steps for troubleshooting, the first thing we have to do is, arrange networking components in a structured and systematic order. This will help us define the problem correctly and give us a clear idea about issues that happen regularly.

The main purpose of a domain-name is to make the website simpler to access. It is easier for users to remember domain names rather than having to remember IP addresses of sites.

Most web developers & system administrators have to do SSH logins to WHM based servers to make the necessary changes there. The default port used for ssh logins is port 22. However there might be unusual circumstances where port 22 is not the default port. In such a scenario we need to identify the default ssh-port used by the server. If you are facing a similar situation then read on to know how to find out the current port being used by SSH on a WHM based server.
