UDP port 1025 Blackjack¿?

["Ballester, David" <dballester () KERNPHARMA COM>]

Hi:
     Anybody knows something about the 1025 port? I make a portscan using
nmap 2.53 over some servers of one of my networks and
I've encountered the port 1025 UDP prot. and the name 'blackjack' returned
as the name service.

Thanks in advance!
