one socket port was occupied by a program
but I don't know which one
How can I find this program out and killed it?
I have known pfile /proc/* can do this,
but I want a more simple method.

You may want to try 'netstat'. It shows related data
structures of all sockets.

If someone connect to this program,
it works, but the fact is always not this
It just listen and no one connect to it.

netstat -a shows all ports that are listening
only the first few ports are tcp and udp ports so use netstat -a |more
if it's a standard unix service you can try more /etc/services |grep urport#
lsof might not be in the defualt path and installation
still try /usr/sbin/lsof

it's platform dependent, on some platforms, it only support files,
while on others, it supports both file and socket.

though netstat tell me some program is listenning on the port
I still don't know whick program it is.
and I can not find lsof in any common bin directory.
Is it a freeware?

Quick fix:
netstat -lepv |more
last colume: PID/Program Name is what you want..
