search for sql servers on network

Label:SQL Server currently has 3 main protocols: Shared Memory, TCP/IP, and Named PipeSharedmemory:The fastest and simplest protocol for Shared memory, a client that uses the Sharedmemory protocol can only connect to a SQL Server instance on the same servers. If other protocols are incorrect, you can connect to the local server for troubleshooting via shared memory.Tcp / ip:TCP/IP is a widely used communica

after all (because the focus of this article is not here, so I will not describe this step here when I use the network vulnerability scanner for information scanning ). Just give up? It's not that easy... just recently, John has been sorting out SQL injection (SQL injection attacks) materials. Now, if you have the opportunity, I can "easily" help it to test it:

/37906349Principle: The default instance listens on port 1433, and if a named instance is installed, the port is dynamically assigned when the service restarts/starts, in order to access the port and start the TCP session, the client sends a request to the UDP 1434 port that SQL Server browser listens on. Additionally, the client sends a broadcast request to the network to
