    Even if you don't run tripwire you can do a basic tripwite
    test against another machine. Build a data base against a
    machine running same OS release/patches that doesn't include
    time stamps or inode number, so record owners, sizes, perms,
    checksums, number of links and compare this to the affected
    machine (booted from alternate media in both cases incase
    the libraries are corrupted on the questionable machine).
    There will probably be lots of false alerts depending on
    additional packages installed, so it takes a while to read
    the output. But, it does tell you if the machine is clean
    or not.

    The other choice is to use the sunsolve fingerprint database
    and check things like inetd, csmd, etc. I'd probably do this
    to thinks that looked doubtful from a tripwire scan.
