# Service Location Protocol on SUSE
|
|
#
|
|
|
|
The Service Location Protcol (SLP) is part of the zerconf concept to provide
|
|
service informations inside a local network.
|
|
|
|
#
|
|
# The client side
|
|
#
|
|
|
|
Your client can search for avaible services using the slp library or via
|
|
using the slptool binary (for scripting).
|
|
|
|
WARNING: Have in mind that you can usually NOT trust the results.
|
|
It is up to the service client to validate the server.
|
|
Do NOT authentificate to an untrusted server or it might be
|
|
possible it gets your password.

Every system which provides a service which should get announced with SLP
|
|
in the network needs also to run the slpd. There are several possible ways
|
|
to announce the service:
|
|
|
|
1) The authors of any service daemon should directly use libslp to
|
|
register the service on the server. Documentation for this can be
|
|
found in /usr/share/doc/packages/openslp/html/ProgrammersGuide/
|
|
|
|
2) Packages without direct SLP support should provide a registration
|
|
file in the /etc/slp.reg.d/ directory. See below for a template.
|
|
You can use the pseudo attributes watch-port-tcp and watch-port-udp
|
|
to make slpd check if the service is listening on the specified port.
|
|
This way a not-running service won't get announced by slpd.
|
|
|
|
3) Administrators can add service lines in the /etc/slp.reg file.
|
|
|
|
4) The slptool can be used to register a service in any script.
|
|
|
|
|
|
Example of a registration file.

|
This could be used to announce the sane daemon running on port 6566
