Port Number Decimal = 1025/TCP

Name: blackjack MSTASK / network blackjack

Purpose: network blackjack

Description:  Microsoftoperating systems tend to allocate one or more unsuspected, publiclyexposed services (probably DCOM, but who knows) among the first handfulof ports immediately above the end of the service port range (1024+).

Related Ports: 1026, 1027, 1028, 1029, 1030

Apparently RPC assigns it's service ports in the 1025-1030 range. TheEnd Point Mapper, which sits on port 135, waits for incoming connectionrequests. RPC then tells the calling program where to find the serviceit's looking for, usually on a port between 1025-1030. The problem isthat it's hard to figure out what the service is! Some spooky MSbackdoor? If I have that port blocked, I could no longer access my ftpserver (Port 21).  By un-blocking it, I found that every connection that was made toftp got one port higher.

NOTE: Do not stop RPC service. It can be disabled, but if you do that, the system may becomes unbootable!
