Sample DCL code for simple client-server task-to-task comms

by sampsa＠mac.com

Yeah, it was running under Linux, I basically took the Linux sources of the PHONE client and stripped it down to the DIR call, then just ran that over the whole nodelist every 5-10 mins. Anyway, this latest thing I've built is literally a few .COM files that talk to a server on RHESUS. sampsa On 21 Jan 2013, at 08:44, Mark Wickens <mark at wickensonline.co.uk> wrote: On 18/01/2013 16:06, Johnny Billquist wrote: On 2013-01-18 07:41, sampsa at mac.com wrote: Half a year or maybe a year ago. Sampsa was running a program which used PHONE to check who was logged in on various machines. When he tried all machines in area 1, MIM got loads of entries in the log for Sampsa's machine trying to talk with machines that were down. (I might be remembering things wrong, and I might be mixing things up, but it was not as if MIM crashed or anything because of Sampsa's code, but I asked him to stop, as he was filling up plenty of logs as far as I can remember.) Yeah, I didn't mean crashed MIM or anything, but caused problems - basically the phone directory just went through the nodelist and did a PHONE DIR to them..If a node was down, the call would fail. It wasn't a good idea from BQT's side :) I don't remember all the details now, but I think it was something with the DECnet stack you used which made this worse. I seem to remember trying the same thing myself in various ways I couldn't trigger the logging. Did you run it under Linux, or what was it? Johnny I seem to remember it was running under the decnet stack on linux?

A simplistic diagram is here http://s295.beta.photobucket.com/user/reinhardtjh/media/DataCenter/Network_… It depends on where in your network you want to put your VAXen. In your diagram, are your VAXen plugged in to the "Local LAN network" ? If so, put your virtual router in this network, and give it a fixed IP address for that subnet. Your virtual router will act as a "router on a stick" - meaning it's got one physical interface. Tunnel traffic will come in via port forwarding from your Vyatta. The virtual router will un-encapsulate the traffic, and route the DECnet traffic back out the same physical interface, where your VAX machines will see it. Your Vyatta will need to be configured to route GRE traffic (which is the packet type for the tunnel) to your virtual router. Ian

Sync serial bridging over Ethernet, was Re: [HECnet] Multi-floor household (DECnet) routing help needed

It's not a matter of them not working well, though, I'd bet...it's more a matter of techs complaining about having to carry around something else. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

That being said, I rarely plug this thing into anything external and the docking station has a DVI port, so if I really wanted an external monitor I'd just use that. -brian
