Having problems with Tripwire on C6, I installed AIDE from the base repository. x86_64 0.14-3.el6_2.2 base 123 k typing: aide result: "Couldn't open file /var/lib/aide/aide.db.gz for reading" (directory is empty and aide.db.gz does not exist.) typing: aide -i (for initialise the Aide database) result: "AIDE, version 0.14 ### AIDE database at /var/lib/aide/aide.db.new.gz initialized." (size 10 bytes) typing: aide result: "Couldn't open file /var/lib/aide/aide.db.gz for reading" typing: aide --init (for the second time) result: "AIDE, version 0.14 ### AIDE database at /var/lib/aide/aide.db.new.gz initialized." (now 2,225,108 bytes) typing: aide result: "Couldn't open file /var/lib/aide/aide.db.gz for reading" action: renaming aide.db.new.gz as aide.db.gz typing: aide result: (noticeable delay) "AIDE, version 0.14 ### All files match AIDE database. Looks okay!" (only 1 file in /var/lib/aide = aide.db.gz) typing: aide -u result: (noticeable delay) "AIDE, version 0.14 ### All files match AIDE database. Looks okay! ### New AIDE database written to /var/lib/aide/aide.db.new.gz" Comment: Looks like I have solved the riddle :-) I did do a 'yum erase aide' followed by a 'yum install aide' to ensure my first experience was not a technical malfunction. -- Regards, Paul.
