Many applications under SUSE Linux Enterprise already 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 with 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-tcp-port
and
description
.
watch-tcp-port
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.
![]() | YaST and SLP |
---|---|
Some services brokered by YaST, such as an installation server or YOU server, perform this registration for you automatically when you activate SLP in the module dialogs. YaST then creates registration files for these services. |
/etc/slp.reg
The only difference from the procedure with
/etc/slp.reg.d
is the
grouping of all services within a central file.
If a service should be registered for SLP from proprietary scripts, use the slptool command line front-end.
