dienst blackjack?
Hallo Liste !

bin gerade am Abdichten meines Systems - dank dieser Liste hab ich schon
einige Schrauben zum drehen gefunden ... aber nmap zeigt mir
einen seltsamen Dienst am laufen, der mir äußerst suspekt vorkommt.
Was bitte schön ist blackjack auf Port 1025/udp ?
Auch der unknown dienst auf Port 1024/udp ist mir verdächtig.

Vielen Dank

Hier mal was nmap meldete:
