Greetings all;

What is /dev/shm?

I've given up on rkhunter ever shutting up about the group and passwd files,
but fussing about this is new.
---------------------- Start Rootkit Hunter Scan ----------------------
Warning: Suspicious file types found in /dev:

And indeed, these files that I nuked friday are back:
[root coyote linux-2.6.30-rc6]# ls -l /dev/shm
total 24

actually have working audio now, so can someone please explain this?  A 67
megabyte file in /dev for an shm device is for what purpose?

I looked at it with mc's hex viewer, and the first 10 or so megabytes are all
$00.  I got tired of standing on the page down key.


Just add these rules to /etc/rkhunter.conf, in the appropriate place:

 # Allow the specified files to be present in the /dev directory,
# and not regarded as suspicious. One file per line (use multiple
# ALLOWDEVFILE lines).
#
#ALLOWDEVFILE=/dev/abc
#ALLOWDEVFILE=/dev/shm/pulse-shm-*
# Adobe Reader (acroread) 9.x
ALLOWDEVFILE=/dev/shm/sem.ADBE_ReadPrefs_[a-zA-Z]*
ALLOWDEVFILE=/dev/shm/sem.ADBE_REL_[a-zA-Z]*
ALLOWDEVFILE=/dev/shm/sem.ADBE_WritePrefs_[a-zA-Z]*
