Various dbus related programs.

[Stef Bon]

Hello,

I'm using a LinuxFromScratch system, with dbus version 1.2.1.

When logging into KDE 4.2.1 as a normal user, and look to all processes 
with dbus in it:

ps aux | grep dbus

mbus      1861  0.0  0.0   7220  2824 ?        SNs  08:58   0:00 
/usr/bin/dbus-daemon --system
root      2822  0.0  0.0   2820   740 ?        S    09:12   0:00 
dbus-launch --autolaunch 7339af1061ab8ae2cc4b507248313a35 
--binary-syntax --close-stderr
root      2823  0.0  0.0   6460  1924 ?        Ss   09:12   0:00 
/usr/bin/dbus-daemon --fork --print-pid 7 --print-address 9 --session
sbon      3328  0.0  0.0   5752  1008 ?        S    09:12   0:00 
dbus-launch --sh-syntax --exit-with-session
sbon      3329  0.0  0.0   6656  2196 ?        Ss   09:12   0:00 
/usr/bin/dbus-daemon --fork --print-pid 6 --print-address 8 --session
sbon      4329  0.0  0.0   3660   608 pts/1    R+   09:47   0:00 grep dbus

I see the systemdaemon with pid 1861, started at boottime. Futher there 
is the "dbus-launch --sh-syntax --exit-with-session" with pid 3328 and 
the corresponding session dbus for user sbon with pid 3329. I can 
explain that one, cause this is started by the startkde script.

The other I cannot explain: the "dbus-launch --autolaunch ...." with pid 
2822, which obviously started the session dbus with pid 2823. I've read 
somewhere that the autolaunch thing has something to do with a process 
trying to contact the sessiondbus which does not exist, causing it to be 
autolaunched. Which process could have done this?? The X server?


Futher what are the numbers 6,7,8 and 9 for? I've read that these are 
filedescriptors, but I still do not understand. Can somebody explain 
these values?

Thanks in advance,

Stef Bon
