Trinux provides ram-based Linux to go.
Want to take advantage of some of the excellent open-source security tools but dont have a ready Linux system at your disposal? Well, to run Trinux, all you need is a 486 or better system, some memory and a floppy drive.
Trinux, the Linux Security Toolkit, is a compact version of Linux that runs completely in system RAM. To set up a Trinux system, I merely downloaded a boot image, created a boot floppy disk using free tools such as rawrite and then booted my system to the floppy. In my case, it took less than 5 minutes to have a fully functional Trinux system up and running.
To add applications to the system, I used the standard getpkg command, which would download the packages from the central Trinux server. Trinux supports almost all of the best security tools, including snort for IDS, a wide variety of sniffers, vulnerability scanners and encryption tools. Trinux also supports Web servers and several scripting languages.
Trinux itself is a very secure system. It doesnt include Telnet capabilities, so it must be administered locally or remotely through an SSH client using RSA encryption.
