Hi, John-san
Thank you very much for your prompt reply!
I feel a bit relieved that these files may not be malicious.
Per your suggestion, I did the following.
Step:
1) copy /etc/rkhunter.conf to /etc/rkhunter.conf.local.
2) configure the two lines below on /etc/rkhunter.conf.local.
* Note: I included "/etc/rkhunter.conf" as well on
"USER_FILEPROP_FILES_DIRS".
------------------------------------------------------------------------
RTKT_FILE_WHITELIST="/usr/bin/mc68000 /usr/bin/mc68010 /usr/bin/mc68020
/usr/bin/mc68030 /usr/bin/mc68040 /usr/bin/m68k /usr/bin/sun2
/usr/bin/sun3 /usr/bin/sun3x /usr/bin/u370"
USER_FILEPROP_FILES_DIRS="/etc/rkhunter.conf /usr/bin/mc68000
/usr/bin/mc68010 /usr/bin/mc68020 /usr/bin/mc68030 /usr/bin/mc68040
/usr/bin/m68k /usr/bin/sun2 /usr/bin/sun3 /usr/bin/sun3x /usr/bin/u370"
------------------------------------------------------------------------
3) run "rkhunter --propupd"
bash-3.00# rkhunter --propupd
[ Rootkit Hunter version 1.3.8 ]
File created: searched for 206 files, found 184
bash-3.00#
4) run "rkhunter -c -sk"
Those 10 files are regarded as known rootkits.

Here is an additional question.
i) [ Warning ] - file properties check
While running rkhunter, "Performing file properties check"
indicated [ Warning ] messages for the commands below.
/usr/sbin/dmesg [ Warning ]
/usr/bin/dmesg [ Warning ]
/usr/bin/kill [ Warning ]
/usr/bin/test [ Warning ]
/usr/bin/which [ Warning ]
/usr/ucb/df [ Warning ]
/usr/ucb/du [ Warning ]
/usr/ucb/file [ Warning ]
Even after I did "rkhunter --update" and "rkhunter --propupd",
I got the same result..
Are those commands affected by anything ? How should I
react those messages or check ? Please advise.
Tnanks!
