No program is a panacea. This sounds like a wonderful tool, regardless. Without knowing the full mechanism by which tripwire works, discussions like this are of limited usefulness. If your system regularly has been compromised to the point that you can't trust your kernel, you shouldn't be trusting Tripwire alone anyway. If we're going to be paranoid, make a miniroot disk, and put all the stuff on there. I kinda doubt it would all fit, however. A floppy with tripwire, related programs, a known good copy of the runtime C library, and the database should be enough. --Dave -- System Administrator, Population Research Institute barr@pop.psu.edu Contains: Carbonated water, high fructose corn syrup and/or sugar, caramel color, phosphoric acid, caffeine, citric acid and natural flavorings.
