    Hi again,

    I have the next problem and I do not know how this could happen:

    I'm running tripwire to check my system each night, now I have a file
    which appears in my tripwire result as changed:
    /usr/lib/libc_nonshared.a
    But I didn't changed it! And in the tripwire-result I can only see the
    md5 and snefru sig's and NO st_mtime and NO st_ctime is displayed!

    The next night I run the tripwire-system again and now the result is OK
    without creating a new database!?

    Some days later another file was changed as the result of the tripwire
    told me:
    /usr/bin/expiry
    The same as described before but I see this changed file in each result
    until it occured the first time.

    Some days later these files show the same behaviour:

    /usr/share/terminfo/h/hp2645a
    /opt/kde2/bin/meinproc
    /usr/lib/locale/ar_EG/LC_COLLATE
    /usr/lib/perl5/5.6.0/unicode/Names.txt

    I'm running:
    - Tripwire version 1.2 (patchlevel 2)
    - SuSE7.2

    This have I done before:

    I have secure copies of all my tripwire databases and I diff my secured
    against the one from the system -- it is OK, they do not differ!

    I took a look in all log's, bash_history and I checked the logins with
    last -- nothing!

    I am running iptables on this machine and only port 53 is open for IN
    and OUT.

    What happens on this machine? I don't think that somebody hack my
    system; perhaps somebody has similar problems and could help me.

    Many thanks and regards
