Hdd Security

i installed it to a hd, and got it all working but i was wondering some things...

when i did apt-get update and apt-get upgrade after it all finished i loged out and went into XP to do some stuff anyway when i went back it was all messed up as it keep retryin to load a usb device even tho i have none connect. then it froze and i had to hit the power button.

is it safe to run knoppix off hd without updateing? if not how can i update and be able to just relog back in like i didnt update... and when i installed it i used knoppix-installer, it had me set a pass for admin and a user, how can i get kdm to work at start up?

and after updateing and all is it safe to run knoppix 24/7 wut i mean is is it safe from hackers? i run my comp at least a month without restarting sometimes is it safe to do that with knoppix?

is there a firewall i can use?

lol ok thats all

EDIT: o forgot to say i allready formated the drive and gona reinstall sometime to night when im done playin some games lol

as for firewall, iptables should work nicely.
safety is best kept with aptget ... to latest versions. OR preferably installing Debaian Stable (3.0r2 iirc) and use all the knowledge out there to secure it.

have to love errors or wut ever they are,

Code:
