ID: Q123257

The information in this article applies to:

Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1, 2.11 SP2, 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, 4.0 SP1

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
