This should be to do with MultiCasting.
1. SLP by default does multicasting
2. Firstly your network router should be enabled to route multicast packets
and secondly your host where the SLP service daemon is running should be
configured for multicasting.
3. To check if your system is configured for multicasting execute the
command 'netstat -nr'. This should show multicast address 224.0.0.0. If not
execute the below command to add multicast routes -
'route add -net 224.0.0.0 netmask 240.0.0.0 dev <interface>'
The interface would be the name of the network interface, for e.g. eth0. You
can get by executing the command 'ifconfig'
4. Now try the same command after restarting the SLP daemon
The command "slptool -s 'EXAMPLE-SLP' unicastfindsrvtypes 10.2.9.3" worked
because you are unicasting; directly contacting the server asking for the
info.
