I suspect a program is listening on port 8000 on my machine.

When I run the following command, I get this error:

> python -m SimpleHTTPServer
# Lots of python error
socket.error: [Errno 98] Address already in use

If I use another port (8000 is the default), the web server runs fine.

If I run wget localhost:8000 from the command line, it returns 404 Not Found.

What can I do (or what tools are available) to find what program is listening on port 8000, and from there where that program is configured?

I tried to use

sudo service networking restart

and

sudo /etc/init.d/network restart

but they both crash the window manager and I can no longer use my keyboard for input into X.

when I use the /etc/init.d/ method it complains saying that I should use the service utility

e.g. service networking restart

but it crashes just the same.

Is there a GUI method of restarting networking?

I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible.

What are the steps to install Broadcom wireless drivers for a BCM43xx card?

I'm a user with no advance knowledge in Linux, so I would need clear explanations on how to make, compile, etc.

lspci -vnn | grep Network showed: 

Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b]

iwconfig showed:

lo        no wireless extensions.
eth0      no wireless extensions.
