Thanks for the help, Mark In general, if/when you have a setup like that, it's the same as if you connect your computer directly to the internet. So, your Linux box is at the same location your DSL router is. So, there are no rules to setup to pass a packet through the router. The reason for the rule is that your DSL router acts as a firewall (and possibly NAT), which is what you need to circumvent for the bridge. No firewall/NAT box in between means no need to punch a hole through it. So you should be able to run the bridge directly on that box, and it should work. All however, also depends on what your mobile operator might be doing... Area number for experimental is probably not going to help you, though. You already have an area. Adding more nodes to it is hardly any different than having a new area setup, except that if you setup a new area, you will need an area router for it. I don't really see much point in the "experimental" area we have reserved, but since we have plenty of areas anyway, there is no harm in it. Anyone using that area can expect things to not work though, as someone else might also be using the same area, and conflict/confusion might follow. As for having several different areas on the same lan, no problem. Johnny

HecNET via 3G Dongle

Guys, Looking to tap into your collective knowledge. I'd like to set up a 3G dongle for the DEC Legacy event. The plan will be to add my machine as an area router then other participants machines into that area. Steve Davidson has pointed out that there are decnet numbers allocated for experimental purposes. I think I understand how to setup my 3G dongle to connect to the internet via an ubuntu machine. I am happy setting up a DHCP and DNS server on the same machine.

CHIMPY's died

by sampsa＠mac.com

Chimpy wont boot for some reason anymore. I've reseated all the RAM, the CPU and PCI cards - but get nothing. Not even the diagnostic beeps. Any ideas? Sampsa

New network card in the Alpha, how do I reconfigureDECNET?

by hvlems＠zonnet.nl

Mark, Since my phone only allows topposting I've deleted the original text. Your question was how decnet devices get their names. The letters indicate the controller, they tell you what hardware is in use. So UNA indicates a DEUNA and ESA an on board controller for a microVAX. After the hyphen follows the controller number, the first interface is nr 0. VMS device names differ: two ethernet controllers may be called EWA0: and EWB0: in VMS and be known in NCP as EWA-0 and EWA-1. The name for the circuit is the same for the line (AFAIK). Serial interfaces (for DDCMP) or CI interfaces follow different rules. Hans Verzonden vanaf mijn draadloze BlackBerry -toestel

Verzonden: 7 september 2011 14:30 Hi, I've got an AlphaServer 300 running as a clustered satellite node from an AlphaServer 1000A. The 300 has a built in DE450 network card (10MB). I've augmented that with a PCI DE500 100MB network card. My question is how I move DECnet off the old card (which is now disconnected) to the new card. I've tried running NETCONFIG but this doesn't seem to recognise the new card. The old card is EWA0: the new one EWB0: The remote booting and cluster server are running fine, so the machine boots OK off the new card, and I have reconfigured TCP/IP for the new card, it's just DECNET I'm stumbling with. The old card won't be connected to the network any more. Thanks for the help, Mark. Verzonden vanaf mijn draadloze BlackBerry -toestel Thanks, I did re-run netconfig and it didn't seem to make any difference, but maybe I got caught in the make change/reboot trap. I've just rebooted and it's working. So for reference could I ask the question of how decnet associates a network controller with the decnet configuration? Cheers, Mark
