port 80 and port 3128

[Noah]

Hi there,

I am trying to figure out what is answering port 80 and port 3128 on my 
server.  I dont have squid installed.

running 12.04 LTS

I halted apache but still see that when I telnet to port 80 and 3128 the 
ports answer.   What are some ways to research the process responsible.

# lsof -i :80
# lsof -i :3128

Cheers,
Noah
