D-Bus is a message bus system - a simple way for applications to talk
|
|
to one another.
|
|
|
|
D-Bus supplies both a system daemon (for events such as "new hardware
|
|
device added" or "printer queue changed") and a per-user-login-session
|
|
daemon (for general IPC needs among user applications). Also, the message
|
|
bus is built on top of a general one-to-one message passing framework,
|
|
which can be used by any two apps to communicate directly (without going
|
|
through the message bus daemon). Currently the communicating applications
|
|
are on one computer, but TCP/IP option is available and remote support
|
|
planned.
|
|
|
|
You will need to create the 'messagebus' user and group before installing the
|
|
dbus package; sample lines to do so are below:
|
|
/usr/sbin/groupadd -g 81 messagebus
|
|
/usr/sbin/useradd -c 'System Message Bus' -g messagebus -u 81 -d '/' \
|
|
-s /bin/false messagebus
|
|
Note that the "\" character is a escape character, meaning that both of those
|
|
lines are actually *one* line. Also note that the numerical uid and gid given
|
|
in the above sample lines may need to change on your system; if you already
|
|
have an existing user and/or group with those id's, then they obviously need
|
|
to be modified for your system. Because the 'messagebus' user and group are
|
|
considered system accounts, the custom is to make their uid's and gid's less
|
|
than 100, but that's entirely up to you. Note that Slackware 12.0 will use
|
|
uid and gid of 81 for these groups, so you should strongly consider using them
|
|
instead of changing them.
|
|
|
|
After creating the 'messagebus' user and group, you will need to make sure
|
|
the /etc/rc.d/rc.messagebus script is run at boot. The easiest way to do this
|
|
is adding something like the following line to /etc/rc.d/rc.local:
|
|
if [ -x /etc/rc.d/rc.messagebus ]; then
|
|
/etc/rc.d/rc.messagebus start
|
|
fi
|
|
|
|
You will also want to stop the messagebus service at shutdown; the easiest way
|
|
to do this is adding something like the following to /etc/rc.d/rc.local_shutdown:
|
|
if [ -x /etc/rc.d/rc.messagebus ]; then
|
|
/etc/rc.d/rc.messagebus stop
|
|
fi
