I'm looking for something similar to these pieces of software to use in Linux (Suse 9.2).
CpuIdle:
Cools down the cpu when it's idle.
DU Meter:
Shows download/upload speeds in a graph that can be opened from the system tray, also keeps data transfer statistics.
Protowall/Windows HOSTS file:
Ip blocking. Preferably some solution that can be switched on and off conveniently.
If anyone can help me out, I'd be happy. I'm new to Linux so I might not understand complicated answers.
I have googled, found nothing for the first two but I found several programs for ip blocking and I'm not sure which one I should choose.
