I DID FIND SOMETHING...NOT SURE WHAT THOUGH ;)

* Filesystem checks
   Checking /dev for suspicious files...                      [ OK ]
   Scanning for hidden files...                               [ Warning! ]
---------------
/etc/.pwd.lock /usr/share/man/man1/..1.gz /dev/.udev
---------------
Please inspect:  /usr/share/man/man1/..1.gz (gzip compressed data, from Unix, max compression)  /dev/.udev (directory)

The contents of the /dev/.udev folder;

drwxr-xr-x  2 root root  540 Jun  8 15:41 db
drwxr-xr-x  2 root root  740 Jun  8 15:41 failed
-rw-r--r--  1 root root    4 Jun  8 15:42 uevent_seqnum


The contents of the ../man1/ folder ;

[root@fwg man1]# ls -al  :.1.gz
-rw-r--r-- 1 root root 40 Jan 22 09:14 :.1.gz

[root@fwgw man1]# ls -al  [.1.gz
-rw-r--r-- 1 root root 40 Jan 22 09:14 [.1.gz


Anything out of the ordinary?

MD5 scan
Skipped  <---  WHY SKIPPED ? bcos OS unknown as shown in the NOTE below?

File scan
Scanned files: 342
Possible infected files: 0

Application scan

Scanning took 32 seconds

....................... end .........................................


NOTE: When we run rkhunter,  rkhunter says the lines below...eventhough i  installed frm the centos repo? but still it says its an unknown OS

Rootkit Hunter 1.2.9 is running
Determining OS... Unknown
Warning: This operating system is not fully supported!
All MD5 checks will be skipped!

Anything out of the ordinary?
