You can search your App Menu (Just open the app menu and start typing your search) for "System Monitor." It is a powerful TaskManager-like utility.

To check network activity in terminal, run

lsof -i

I just typed it in and got this, what do you make of this?

~$ lsof -1
lsof: illegal option character: 1
lsof 4.89

It is

lsof -i

Not -1. The letter "i".

I think this, along with double dashes appearing as one long dash in the forum font may be grounds for improvement of the forums display. I think I will cite this thread in that suggestion box.
The forum font needs to be more legible.
