How to use Telnet

When working with port Telnet is with a simple command you can test whether a port is open. Issuing the Telnet command telnet [domainname or ip] [port] will allow you to test the connectivity this allows you to quickly narrow down where an issue is. Often a network or SQL port issue. 

The format of the CMD command is:  telnet [domain name or ip] [port]

Put the IP address or domain name of the server you are trying to connect to in place of [domain name or ip], and replace the second brackets with the port number on the remote machine connection to which you want to test.

For example, to verify a connection to MS SQL Server would look like the server IP address 192.168.1.100 on the default port 1433 for MS SQL Server. The command will look like:

telnet 192.168.1.100 1433 (notice the space between the IP and port).

If the connection succeeds, a blank screen will show up, meaning that the computer port is open. A failed connection will be accompanied by an error message. It can indicate either a closed port or the fact that the indicated remote server is not listening on the provided port.

telnet 192.168.1.100 1433

When the connection is successful the screen will look blank
