Hi there, I played with SLP 10+ years ago and thought it was pretty much dead, but it seems it's still being used to advertize printers -- wow!

It used to be possible to list all services on a network, but I think nowadays you have to list all servers and then list all service types (findsrvtypes) and then all instances of this type (findsrvs <type>). > 2.

The trend seems to be for individual services to advertise themselves over mDNS/Bonjour rather than anything centralized and/or SLP. > 3.
