I rebuilt rkhunter-1.2.8-1.noarch.rpm by using the spec and tgz from the rkhunter site (www.rootkit.nl). (I rebuilt it using his instructions.) However rkhunter does not do an md5 check. The box used to have fedora and each time there were updates it would complain that the some of the md5's don't match. I contacted the author using his contact feature on Wednesday but he hasn't replied. I know Karanbir's repo has 1.1.9 (as does fedora development), but i thought I'd have the latest.
The box has
# cat /etc/redhat-release CentOS release 4.2 (Final)
which is supported in the os.dat file in rkhunter.
Output from this morning's mail :-
