Is it normal to have rtkit - daemon running ?

[johnhoffmann]

I am no expert and heard about installation of a rootkit by hackers. So I wanted to ask you: when I do a ps -ef I find this porcess:


rtkit 1736 1 0 15:54 ? 00:00:00 /usr/libexec/rtkit-daemon


Is this a normal process in fedora 12 , or I somebody hacked my server ?


Thanks

john

Yes, it's normal.

BASH:~/-> rpm -qf /usr/libexec/rtkit-daemon

Thanks, will connect the server back to the internet !!

AFAIK, it's only installed and used by pulseaudio presently.

[PabloTwo]

@vallimar, interesting piece of info. I checked the "requires" of pulseaudio and, sure enough, rtkit is in the list.

BASH:~/-> rpm -q --requires pulseaudio | grep rtkit
rtkit

[guzenkov]

This command is probably more appropriate as it will show all the installed package that require rtkit as a dependency:

# rpm -q --whatrequires rtkit
pulseaudio-0.9.21-14.el6_3.x86_64
