When an instance of SQL Server starts, if the TCP/IP or VIA protocols are enabled for SQL Server, the server is assigned a TCP/IP port. If the named pipes protocol is enabled, SQL Server listens on a specific named pipe. This port or pipe will be used by that specific instance to exchange data with client applications.

In fact, in both cases, we may have port conflicts depending on which…
There are two ways to create an SSH tunnel, local and remote port forwarding (there’s also dynamic forwarding, but we won’t cover that here). The best way to understand these is by an example, let’s start with local port forwarding. Imagine you’re on a private network which doesn’t allow connections to a specific server. Let’s say you’re at work and imgur.com…
