Question : NETSTAT
|
|
Typing netstat -an, I get a bunch of connections to *:* near the end of the output. What are these all about? It's not showing a normal ip. Does that mean I can do the same for my ip when others type netstat -an on their systems...
ThanX in Advance

Answer : NETSTAT

If you notice the protocol column, you'll notice that these are UDP ports. Unlike TCP, UDP is a connectionless protocol. This means that there is no need to make a connection before transfering data, you just send what's called 'datagrams' - Small packets of data to the remote machine. The list of UDP ports in netstat are simply open UDP ports on your machine. Since there are no connections in UDP then there is no remote IP that is connected - Therefore netstat writes *:* instead.
