Please, no nonnonononono.....no. AAAUUUGH! I don't even want to think about IP over PVM (although, yes it does work...8-)). I want to get the VM telnet server disentangled from the stack code so I can fix all the IPV4 dependencies in the existing code without having to mess with all that undocumented *CCS nonsense or dynamically creating LDEVs from inside a Linux guest. PVM already has all the necessary interfaces to CP LDEVs, VTAM, other session managers, and everything else necessary to do that job -- and has both a IUCV and CTC interface that I have Linux capabilities for already. PVM sessions get multiplexed over a single physical connection, which maps nicely to what I want to do. PVM neatly encapsulates all the necessary terminal support in a way that is simply mapped from a Linux TCP session to a PVM session. What I've been working on is a Linux appliance that supports a modified telnetd that talks to PVM via a IUCV or CTC connection. IPv4 or IPv6 tn3270/tn3270e connections are mapped from the appliance to PVM sessions, which can connect locally or to any PVM-defined resource. The VM TCPIP stack or telnet daemon is not used at all for this purpose. A session ID can be passed via tn3270e and the named PVM resource is selected. Routing to VTAM or other systems is automatic and invisible to the client system (no DIAL processing or SPECIAL definitions necessary for PVM). It's still in prototype form, but I have functioning code that supports IPv4 and IPv6 clients directly. I still need to work on printer LU support, but the basic function is up and running. Now, all I need is how to talk to SFS servers directly over IUCV/APPC...8-) -- db
