    Hi

    I have an odd problem on more than one 2.6 based systems. Every so often
    one or more (two did it last night) the permissions on some of the files
    are changed from the original to -rwxrwxrwx. This happens in various
    directories as far as I can see. The dates on the files remain as they
    were originally. As these are on a private network, I do not immediately
    suspect hacking/rootkit, but would like to have anyones experiences of
    similar occurrences.

    The most recent change was to the /etc/pam.conf, /var/adm/utmp and
    /var/adm/wtmp files, although it does appear that many others have been
    affected.

    Any chance that ufsdump may be causing it?

    Thanks

    Peter
