SLP installation source fails when description line in reg file contains round brackets ()
This document (7003086) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Linux Enterprise Server 10 SP2
Situation
To reproduce the issue:
Create a server installation source and check the 'advertise via SLP' option.
This should create, /etc/slp.reg.d/YaST-xxxxx.reg.
Ensure the 'description' line in the '.reg' file contains round brackets () - it does by default.
Boot another server with the SLES10sp2 disk.
At the install screen, select F4 > SLP, and install.
This should fail to find the SLP install source.
Remove the round brackets from the 'description' line in the '.reg' file.
Restart 'slpd' and try again; this should work.
Changing options in the /etc/slp.conf appears to make no difference.

Resolution
Workaround
The round brackets in the 'description' field are reserved characters, if brackets are required square brackets [] are legal characters to use.
Once the round brackets are removed/replaced restart SLP:
/etc/init.d/slpd restart
Fix
This issue has been fixed in the following patches:
- yast2-instserver-2.13.18 (SLES10 sp3)
- yast2-instserver-2.18.1 (SLE11 sp1)
