Sentry Firewall CD TM   [ www.SentryFirewall.com | Sentry.SourceForge.net ]
CDROM-Based Firewall/Server/IDS(Intrusion Detection System)
Now this is some CD. You boot from this CD, and with a few preconfigured files on a floppy (on which you've flipped the write-protect switch to read-only) you have a running firewall.
   David A. Bandel, Linux Journal Magazine.

You can use Sentry as-is or customize Sentry to build your own custom solution. The ISO image is a free download, and there's plenty of documentation on the Sentry web site to help you get started.
   Joe "Zonker" Brockmeier, Linux Magazine.


[ 03.18.06 ] As many of you have probably already discovered, development of the Sentry Firewall CD has been sparse for the past year or so. I regret that I simply have had very little time to continue development of this project. So, for now, it seems that the Sentry Firewall CD project has stalled indefinitely. I will certainly keep the community updated if this situation changes.

I would like to say that I've had a great time working on this project, and I've really enjoyed working with all of you. If you take a look at the README file that comes with the CD (and is also available on this website) you will see a short list of folks that have contributed in some way to better the Sentry Firewall project. I know this list represents only a very small fraction of the community that has actually contributed. If you have contributed at all to this project in the past and your name is not mentioned in the README, then please email me so I can add your name.

Also, if there is someone out there that would like to take what I've done with the Sentry Firewall CD and continue to update and develop it, I would most certainly love to help. I am also open to allowing some individuals make use of the Sentry Firewall name and this website to continue development of this project in a more community-based manner. Please feel free to contact me if you are interested in taking on this project.

Thank you all again :-)
