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.....
