How secure is this? - experts needed!

I had an opportunity to re-install Knoppix as the Debian type (option in 'knoppix-installer') and decided to check how secure the default configuration is. The last install I did I included Arno's firewall script and this did seem to be completely secure. So I used the Sygate scan website to check:-

http://scan.sygate.com

So, the default installation comes back with:-

UDP ports - 'open' 135 location service & 111 SUNPRC
TCP/IP ports - 'open' 68 ?, 111 SUNPRC and 631 ?
ICMP type 8 - open
Trojan scan - no results
Stealthscan - all ports closed but not 'stealthed' - i.e. visible

This doesn't seem to bad to me..... what do people out there think?

(I'll put Arno's script back on anyway!)

Stu.....

knoppix is one of the most secure distro I have ever came accross.

bottom line. security is in the eye of beholder.

If your are not satisfied with this results just install a firewall
for example firestarter and you will be able to close ports or stealth
them how you like, if you are just runnning from the cd I can almost not imaging a safer opportunity, but then if you are really paranoid
just disconnect your harddisk(still left something to be afraid off??)
