Nmap's list carries the older label admd, the administration port of Chili!Soft ASP, a product discontinued long ago, and notes Yahoo pager traffic as another historical squatter. None of those are live software today, so treat 5100 as an unclaimed number in the 5100-5102 block and fingerprint whatever answers.",
