Good Morning,


I did an update from a clean install (running Mandrake linux8.0) and this is
what I got back the next morning.

Security Warning: Change in Suid Root files found :
                - Added suid root files : /usr/lib/squid/pam_auth

Security Warning: Changes in Suid Group files found :
                - Added suid group files : /usr/lib/squid/pam_auth
                - Removed suid group files : /usr/bin/gpg

Security Warning: the md5 checksum for one of your SUID files has changed,
        maybe an intruder modified one of these suid binary in order to put in a
backdoor...
                - Checksum changed files : /usr/bin/crontab
                - Checksum changed files : /usr/bin/gpg
                - Checksum changed files : /usr/bin/procmail
                - Checksum changed files : /usr/bin/ssh
                - Checksum changed files : /usr/bin/sudo
                - Checksum changed files : /usr/libexec/pt_chown
                - Checksum changed files : /usr/sbin/pppd

Question, what are some of the reasons besides the obvious (being rooted or
backdoor setup) I would get this and  how do I correct this problem with
reloading the whole system AGAIN if possible. This is the Fifth time I've got
this message and I'm using Mandrake update, I thought Mandrake update
checked for these types of problems.

I live in Japan, using a dial-up connection, could this be a problem?? just
asking.
GOD BLESS YOU ALL and thank you for your help.

Sincerly,
