mapping local ports to applications....

[Mia_tech]

is there a way to know what connections or ports are related to what application....let me explain, for example when I use netstat to find out my open connections.

jorge@ubuntu-box:~$ netstat | grep tcp
tcp 0 0 ubuntu-box.lakesh:56229 2k3server-:microsoft-ds ESTABLISHED
tcp 0 0 localhost:4443 localhost:35543 ESTABLISHED
tcp 0 0 localhost:35543 localhost:4443 ESTABLISHED


I know that everything that has "www" is web app usually connection to the browser, or pop3 email, but there are cases where it doesn't indicate an application just the port number and I would like to find a way to map that port to the application that is using it... of course without having to search google for ports ;0)

any help appreciated

thanks

Hello,

netstat offers a -p argument to print process ID and name along with the port number. You need to have root privileges to see non user processes. So try...

sudo netstat -p

See the man page for more options/information...

man netstat
