- HECnet - lists @ Update

Others DECnets (was: Boot VAX from Alpha host Infoserver?)

by jeep＠scshome.net

Testing has been delayed for the LAVc configuration until this weekend - work has a habit of getting in the way of hobbies. In my version, I continue to use the same bridge.conf file except that I have added the following: [mop] [sca] [last] I did not want to force MOP or LAT on a site that only needed one of them so I split them out. This version has only one file with the appropriate sites/areas included or commented out to keep things cleaner/easier. Current testing is with two other sites. One is in the US via the Internet, the other is here (multiple static IP addresses are a wonderful thing). I would be interested to see what may be the differences in my version and the one you are using. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of gerry77 at mail.com Sent: Thursday, December 03, 2009 16:38 To: hecnet at Update.UU.SE Subject: [HECnet] Others DECnets (was: Boot VAX from Alpha host Infoserver?)

I'll take advantage of this message to say that here in this mailing list I'm a little bit like an impostor, because in truth I'm not a member of HECnet, but of another Hobbyist DECnet based in Italy. :-P We are now running a quite modified version of Johnny's bridge: we departed from his project because some of us have connection and bandwidth issues that prevent the development of a strictly star-topology network as required by the HECnet bridge. We started experimenting many years ago (in the 2002-2004 timeframe) with Multinet and TCPware tunnels but were not happy with that solution because many of us had (and some still have) dynamic IP addresses which forced a tunnel recofiguration at every address change! At the time, we already did know about HECnet but not about the bridge, either because it didn't yet exist or because it was still unpublished, so we were forced to abandon out dreams of a DECnet of ours. About three years ago, in the first days of december 2006, we learnt about the bridge and started again our experiments, but we soon understood that we were in need of some changes (among other things we had some nasty packet loops in the first days), so we asked to Johnny the permission to modify his work and here we go: our network is nominally made up of about 30 nodes, all in the same area, but only three to four are online 24/7, and has a full mesh topology, that is every bridge is connected to every other bridge (but we later added a feature that allows for mixed topology networks). If someone is interested in the full feature list and other details, such as some DECnet tuning we needed, s/he can contact me off list. :-) Going back to the original topic, we choose to keep LAT and MOP together, and added LAST to the same group of protocols (but we renamed the .conf section from [lat] to [lan]). Instead, we didn't ever consider transporting SCA across the Internet because it's too much a time-sensitive protocol and would be probably almost useless, at least here. Did you succeeded, Steve, in keeping on quorum a cluster across the bridge and the Internet? Cheers, G.

So, when are you finally going to join HECnet? :-) Johnny gerry77 at mail.com wrote: On Sun, 29 Nov 2009 14:56:39 -0500, you wrote: My version splits out LAT from MOP, adds SCA (LAVc) and LAST (InfoServer).
