How to find out process associated with the port number?

Thanks.

Hi,

The easiest way to do this is to install 'lsof' You can obtain an already compiled version here:

hi,

lsof is "the best" to find the info.

Here's an example of lsof usage:

To which files are open for a given process id (pid)

# lsof -p

To see all the open files associated with a particular command.

# lsof -c midaemon

User name.

# lsof -u
# lsof -u

processes being used via a socket.

# lsof -i tcp:23
# lsof -i udp:123

hi

lsof is the best command to use. for example to find processes associated with the port number 1521 (oracle port) issue

lsof -i:1521

for telnet (23)

lsof -i:23

iam attaching lsof binary, u unshar it and u can use it if the OS is 11.00
