about lsof

Hi,
I typed lsof -i :80 in my putty but i am not able to get sockets related to port 80

Can any one help me out soon

Can anyone point out the reason for not able to get the related sockets

Output of what i am getting in my putty is displayed below

training@use:~> lsof -i :80
training@use:~>

may be no application is bind to this port. This port is free.
Check with netstat

Thanks for ur reply

I am getting this while using netstat

LISTEN
LISTEN
FIN_WAIT2
CLOSE_WAIT
FIN_WAIT2
TIME_WAIT

probably you dont have the required permission.

I am getting all those things like IP address all in netstat but not getting anything in lsof
