I never understood what the hell the session layer was for anyway - I figure anything above layer 3 (transport) should be handled by apps, not by 4 layers of network stack.

Getting SNMP to the brouter should be easy, need to work out how to do the same for GRE. Will get back to you once I have worked it out. Regards Rob From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Brian Hechinger Sent: 29 September 2013 22:07 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Connecting to HECnet from DEC Legacy 19-20 Oct To work behind a NAT box you'll need to be able to pass SNMP and GRE through to the DECbrouter. If you can do that you'll be golden. GRE doesn't run over a port, it's a Layer 4 (transport) protocol. SNMP is 161. The email address is just where you want notification emails sent so your normal email is probably appropriate. The emails that are sent can also be copy and pasted into the router in the event that SNMP doesn't work. -brian On Sep 29, 2013, at 4:00, "Robert Jarratt" <robert.jarratt at ntlworld.com> wrote: I was going to have a go at this today, but thinking about it I am not sure this can work at DEC Legacy or even here at home because it would always be behind NAT.

Hello! Odd. I'd thought that they would be named Hagar and Hamlet. When those things first came out, the advertising being used was indeed from Hagar the Horrible, a Viking. In fact I even have a mouse pad from it...... And there's a reason why those shell commands were beyond the comprehension of regular people. They were not written by people..... ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

To work behind a NAT box you'll need to be able to pass SNMP and GRE through to the DECbrouter. If you can do that you'll be golden. GRE doesn't run over a port, it's a Layer 4 (transport) protocol.

It is good fun but those panels kept me well away from IBM systems. AIX had something similar as an aid to system managers. I forgot its name but it was a blessing because the shell commands were beyond human comprehension... Van: Sampsa Laine Verzonden: zondag 29 september 2013 20:36 Aan: hecnet at Update.UU.SE Beantwoorden: hecnet at Update.UU.SE Onderwerp: [HECnet] Humour value alternative to DCL - a port OS/390 ISPF to VMS :) Not sure how many of you guys know about the "simple" user interface that IBM developed for using TSO ("time sharing option", the interactive bit of MVS / OS/390 / z/OS) and it's called ISPF. It's basically a set of screens that invoke TSO commands on behalf of the user (mostly to compile / link programs, which is insanely complex on IBM systems for some reason). Anyway, I thought it might be amusing to write an ISPF clone and deploy it on CHIMPY - because I'm lazy I'm going to do it in Python (so it prob will never run on a VAX), but I'll let you guys know when it's finished. Basically I think I'll just define a "Panel Language" that is used to describe the menu and what DCL command to run if that option is chosen. If I feel particularly ambitious I might include 3270-like cursor key navigation of the panels as well :) NOTE: This is not a serious endeavour, more of a "wouldn't it be funny if this looked like a mainframe" type idea..

This is a little bit unfair for the blue guys :) ISPF is far more than a set of screens to invoke TSO commands. The panels (that's how ISPF screens are called) are just a part of the whole thing. ISPF integrates with TSO, so we are talking about: - The TSO command language (CLIST language) and also the REXX language. - The panel facility. - The skeleton facility. It is quite easy to "simulate" the ISPF panels (you just need DCL to do it, I did it when I worked with DEC machines in a mostly IBM-centric company), but that would be just the user interface. The APIs provided with ISPF are way beyond that... I was planning on developing a simple format for defining the panels, mapping the options to DCL and any params / switches they need. I am aware that ISPF can be used for way more than the basic IDE / sysop functions that it comes with by default, don't some ISVs actually build their software using ISPF panels as the interface? I just thought a IBM mainframe lookalike interface to VMS would be amusing if nothing else. Sampsa
