However, areas are a rather limited resource, and we are slowly running out of them. Sampsa, do you really think three areas are motivated? DECnet was not designed with the idea that physically separate places needed separate areas. Areas are more of a logicial division thing (although some constraints do exist on areas). I'll be happy to remumber should this happen... sampsa

Sampsa's goal here is mapping HECnet. My goal is to write a data mining service that just happens to provide the data that a mapper would use. To that end, I'll be stashing all this data in a database of some sort (details unknown as yet, see below) A centralized repository of data is nice in many ways, but it is a headache to manage. Absolutely it is, but if people are already putting INFO.TXT files out there they are doing 99% of the work already, we just need to get the data in a single place. That said, I could be convinced of setting something semi-automatic up. A reasonable way would be for people to give me machines to poll, and then I'd setup an automated process to poll those machines for files in a specific format. I can then create a database out of that, and make it available through the web, as well as over DECnet, and also as a summarized file. Anything would be pretty easy if we just have the data collected. I think this would be fantastic. I already have something of a start for this in the form of my database of nodes in HECnet. I'd need to extend it with more fields, but that would be pretty easy. It's all in Datatrieve today, and that should be accessible over DECnet right now (even though I seem to remember that VMS hosts had some problems with that). I'll have to learn how to access that db. I'm already extracting information from that database for the hecnet web-page on MIM (accessible as Madame). So, if we can just decide on what we want, and how to make the information available, I'll sit down and write the code to fix it. Do you want to also store my data or should I do that myself? I might do it myself at least for now until I know what exactly I need/want to save. -brian

It's not happening 100% of the time. Fair 'nuff... Make certain you maintain space around the ';' or DCL parsing may think it's a file version separator. Since the ';' was already spoken for in VMS, applying unix pipeline syntax requires that spacing for the ';'. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.

I'm using is.popen(), so yeah, i think i'm out of luck in that case. I'll just have to add some logic to maybe re-try the node if I get this.

It would be nice if the discovery was purely decnet. True. Well, if one can define access lists using DECnet addresses as filter terms, I'd be ok with that, for nonprivileged access. I've just verified that a MOP console request works from Linux using locally-stored authentication on the IOS side to establish a nonprivileged IOS CLI session on a 7206VXR running IOS 12.3(22), like so: $ moprc -v <MAC address> ...and like this from NCP under VMS: NCP> connect node gw physical address <MAC address> via <circuit-name> Note that the MAC address must have its octets delimited by colons under Linux, and hyphens under VMS. This is a service (protocol?) called Console Carrier Request. If you have Phase V, I think you use SET HOST/MOP under VMS. Under RSX, there is a special program called CCR that you use. And correct, this is not a routed protocol, so you need to be on the local network, and you cannot go through NCP on another machine using TELL. :-) I'm going to play with this. I think this is the solution to keeping cisco queries in-band. I'll report back on how I plan on using this. -brian
