The information in this article applies to:
  • Microsoft SNA Server for Windows NT, version 2.1

SNA Server uses the following socket numbers to support SNA Server clients over TCP/IP (over Windows Sockets):

0x05C5 - Socket used to receive SNA application traffic (3270, APPC). This 

         is the socket used to communicate to the SNA Server service.
0x05C6 - Socket used to support SNA Server client "sponsor sessions". This 
         is the socket used to communicate to the Snabase service over
         which the client workstation receives a list of other SNA Servers
         running in the domain.
The SNA Server client socket number is allocated dynamically through the Windows Sockets interface.

In addition to TCP/IP protocol over Windows Sockets, Microsoft SNA Server version 2.1 clients use the following to communicate with the server:

  • Named pipes (over any local area network [LAN] transport supported by the Microsoft network redirector included with Windows for Workgroups, Windows NT, or LAN Manager)
  • NetWare IPX/SPX
  • Banyan IP (over Banyan Vines)
  • AppleTalk
