I am trying to determine if IBM's TCP/IP for MVS can support multiple IP
addresses which would be tied to specific MVS applications on the same
machine. For example, suppose we had the following applications:
128.103.1.xxx - library.harvard.edu - CICS01
128.103.1.yyy - telephone.harvard.edu - CICS02
128.103.1.zzz - tso.harvard.edu - TSO01
where "library" was a CICS application that would put the user directly
into an online library catalog, "telephone" would put the user directly
into a CICS application providing an online telephone directory service,
and "tso" would put the user into tso.
I believe that a single network interface like a BTI box or 8232 could support
such a configuration. (Actually, the network interface wouldn't care)
Could the IBM TCP/IP for MVS product allow multiple address spaces like
TCPIPLIB.PROFILE, TCPIPTEL.PROFILE, and TCPIPTSO.PROFILE to support the
different applications?
Is anyone out there doing something like this?
Your thoughts and comments will be most appreciated. ThanksELINSKY@YKTVMZ.BITNET (Jay Elinsky) (03/01/90)
I assume that you want a Telnet session to connect directly to a different
application depending on which IP address was used. You could run multiple
TCPIP address spaces, each with a different default Telnet server application.
The 8232 would be connected to one of the TCPIP's, and the others would be
connected to that TCPIP as described in "Linking Two TCPIP Address Spaces"
on page 5-9 of the Installation and Maintenance Manual.

Would it be possible to bind each of these services to a well-known port in tcpip? The numbers above 512 aren't reserved and can be used by a site, so to map your request- telnet 128.103.1.xxx -p 644 for library... telnet 128.103.1.xxx -p 655 for telephone telnet 128.103.1.xxx -p 666 for tso (the choice of tso port number is not a commentary... ;-)
