[Eug-lug] firewallls

[Jim K]

I have 2 questions. I have a laptop running Ubuntu feisty fawn to access 
the internet for e-mail and surfing the net.
1) Does anyone have a favorite firewall that is easy to setup?
2) Does anyone have an easy to use gui application to control the 
daemons running?
  I have had a major slowdown the last several days and now cannot 
access the internet under feisty.
The last thing I installed was skype. There are a number of daemons I 
don't recognize and figure stop them and put up a firewall and see what 
happens before I do a reinstall.
