[wellylug] Tools

[Cameron Hart]

Hi I'd like someone to point me towards the right tools to use for the job 
I want my Linux box to do. What I want to do is have my Linux Box to be 
sharing the internet, and to also be a web server (only for my LAN), _and_ 
to be downloading from the internet only when there hasn't been any traffic 
masqueraded for half an hour.

I think I can do mostly everything here by reading all the How-To's and 
other instructions, but I don't know how I would test to see if there had 
been any traffic Masqueraded for the last half-hour. Also, I don't know how 
to set up Apache to run a local command when you click a link on the web 
page (I want my LAN users to click on a link to manually stop my 
downloading, but my downloading prog to start automatically)

Can anyone point me towards the right tools to use?
Thanks to anyone in advance if they can help.
