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.

Warning: Suspicious file types found in /dev:

And indeed, these files that I nuked friday are back:

Do you have some Adobe stuff installed? And might you ever accidentally have

Anything with 'pulse' in its name has been nuked by an 'rpm -e', and I
You should have not, but it is your choice.
Is there a better way to get rid of PulseAudio? Some install option which
prevents infecting the system in the first place?
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]*
