Light bulb goes on above head -- check out LIDS (lids.org) -- I haven't used it in a while, but the short summary is that it provides mandatory access control for Linux. If you set up your entire system to be protected by it, a lot of stuff will break and it'll probably take a few days to get things working normally. However, if you just want to protect the one file, you should be able to set it up so that nothing can modify the directory it resides in, and explicitly allow /usr/bin/netscape (or whatever) full access to the directory. That way, users will not be able to delete the file from a shell, but Netscape can continue to do its thing normally. Hope this helps, Terry #include <stddisclaim.h>
