netstat

Hi
what is the command to see the process name/application name
along with the port number, connection status ...

netstat is not giving process/application name

Is there any way to know which application is holding which port?

Thanks in advance

u can see in /etc/services for the standard port allocation.

For standard applications, /etc/services is O.K.

For non standard applications, is there any way to know process/application name vs port number

Try lsof
It is not installed by default

On windows XP/2003, You may try netstat -aon
