I enabled ALLTEST in /etc/rkhunter.conf and put a # on the DISABLETEST list. I feel comfortable now that I have a handle on what I'm running on my system. I ran rkhunter and as I expected it gave me these warnings. All these processes are recognized and valid applications and presumably they are deleting these respective files because they don't need it anymore. There's nothing to see here. These aren't the droids I'm looking for.
I have to whitelist these processes. The basic syntax for that job is : ALLOWPROCDELFILE=/path/to/process. You can specify the specific file with : ALLOWPROCDELFILE=/path/to/process:/path/to/filename.xxx.
For example: [19:19:35] Process: /usr/bin/pulseaudio PID: 784 File: /memfd:pulseaudio
append to /etc/rkhunter.conf
ALLOWPROCDELFILE=/usr/bin/pulseaudio
Another example: [19:19:35] Process: /usr/bin/gnome-shell PID: 1151 File: /tmp/mutter-shared-67ER4Y
append to /etc/rkhunter.conf
ALLOWPROCDELFILE=/usr/bin/gnome-shell:/tmp/mutter-shared-67ER4Y
You can also use * to represent any character.
Anytime you make changes to /etc/rkhunter.conf don't forget to run the command : #rkhunter -C #to check the config file
