Many applications in openSUSE have integrated SLP support through
the use of the libslp library. If a service has not
been compiled with SLP support, use one of the following methods to make
it available via SLP:
/etc/slp.reg.d
Create a separate registration file for each new service. The following is an example of a file for registering a scanner service:
## Register a saned service on this system ## en means english language ## 65535 disables the timeout, so the service registration does ## not need refreshes service:scanner.sane://$HOSTNAME:6566,en,65535 watch-port-tcp=6566 description=SANE scanner daemon
The most important line in this file is the service
URL, which begins with service:. This
contains the service type (scanner.sane) and the
address under which the service is available on the server.
$HOSTNAME is automatically replaced with
the full hostname. The name of the TCP port on which the relevant
service can be found follows, separated by a colon. Then enter the
language in which the service should appear and the duration of
registration in seconds. These should be separated from the service
URL by commas. Set the value for the duration of registration between
0 and 65535.
0 prevents registration. 65535
removes all restrictions.
The registration file also contains the two variables
watch-port-tcp and
description.
watch-port-tcp links the SLP service
announcement to whether the relevant service is active by having slpd
check the status of the service. The second variable contains a more
precise description of the service that is displayed in suitable
browsers.
/etc/slp.reg
The only difference between this method and the procedure with
/etc/slp.reg.d is that all services are grouped
within a central file.
If a service needs to be registered dynamically without the need of configuration files, use the slptool command line utility. The same utility can also be used to deregister an existing service offering without restarting slpd.
