[NTLUG:Discuss] CD-Rom bootable Firewall w/ Services

[Bug Hunter]

  A possibility.  There are things out there that allow you to make 
bootable cdroms.  They essentially take a bootable floppy and turn them 
into a file on the cdrom.

  I would take smoothwall, install it, and get the info stored in its 
scripts.

  Then, I would take the knoppix lite distribution and copy it using dd to 
a file, and mount it with the loopback feature. 

  I'd then copy the files to another (ext2) file system (using loop again) 
and make changes to the scripts, then use a cdrom program (mkisofs) to 
turn it back to a cdrom image, burn it and be done.

  Of course this is a long way around.

 look at user-mode-linux.sf.net for links to makeing files into file 
systems and mounting them.  Expect to spend a few days looking at things, 
a lot of info is there, but is scattered.

  If you use user-mode-linux on the file system you built, you can test 
ahead of time, but you need to set up bridging on your system to make 
ethernet easier to play with.
