Linux Port
 
how to check particular port status used by users in linux.

say an example-

If vsftpd / named running by user XX, how do i know port 21 / 53 are using by user XX

from top -c, i can view the pid and user name.. but here i want to grep this info from port number.

Thanks

Do you mean something like:

Code:
fuser 21/tcp
(grab process number from list)

Code:
ps aux | grep 1234
username of the process is on the left

correct.

Code:
lsof -i 4 | grep 1234
is another way to do it
