Hi. Ian McLaughlin wrote: Here's where I read about hidden areas: http://labs.hoffmanlabs.com/node/271 Hmm. Interesting article, although slightly wrong or imprecise perhaps. What they refer to as "named objects" are actually numbered objects. Named objects are the ones which aren't predefined in any way, and are for random program communications. For instance, MAIL is never refered to by a name, but instead by it's number, which is 27. All "well known services" have specific numbers assigned to them. Basically, if you have a network like this: ME => ROUTER => YOU Where ME:: and YOU:: are in conflicting areas, and ROUTER:: is a level 1 router between two level 2 routers, you would get from me to you using: ROUTER::YOU:: I haven't tried it, but it might be worth an experiment. It's called poor mans routing (PMR), but I haven't seen it used for exactly that purpose before. However, I doubt it can be solved that easily. In the level 1 router in the middle, you cannot get access to all nodes on both sides, in case you have an overlap of areas on both sides. However, as Steve is trying it, as a hidden area 63, it becomes possible. The level one router will only have one area 63 it knows about. And nodes inside that area 63 will not know of any other area 63. So it should be doable. He just needs to keep the physical networks separate, and it should just work. Johnny Ian.

They used to call that poor-mans-routing (PRM), and yes that is basically how it worked. ZKO has over 3000 machines and only had areas 2 and 19. The fix was hidden area support which in this case meant anything from either 63, or 62. I don't remember if they used areas 61 or 60. I managed machines in area 2, 19 and 63. My area 63 nodes were on satellites of clusters (in either area 2 or 19) that has DECnet aliases Worked very well. For those who were unfortunate to not be attached to a cluster PMR was the only way to either send mail, or SET HOST. -Steve From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Ian McLaughlin Sent: Thursday, December 03, 2009 18:56 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Others DECnets Here's where I read about hidden areas: http://labs.hoffmanlabs.com/node/271 Basically, if you have a network like this: ME => ROUTER => YOU Where ME:: and YOU:: are in conflicting areas, and ROUTER:: is a level 1 router between two level 2 routers, you would get from me to you using: ROUTER::YOU:: I haven't tried it, but it might be worth an experiment.

I think it makes sense to split out the different protocols in more detail. I wouldn't mind allowing MOP to all places, however, LAT is something I prefer to be a little more cautious with (just as an example). Johnny Steve Davidson wrote: 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?)

Ian, Are you talking about hidden area support? That is one of the reasons that I modified the bridge. Area 63 in HECnet is hidden (sort of...). At the moment it only exists at my end but... It turns out it is a bit more complicated than I had ever imagined. I did find some notes about how it was done in ZKO (Spitbrook Rd, Nashua, NH) but I'm a long way from making it actually happen. One component involves two different copies of the databases - but that is only the beginning. -Steve From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Ian McLaughlin Sent: Thursday, December 03, 2009 18:43 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Others DECnets Maybe a bridge between the two?

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?)
