Hi list. I'll introduce myself later when I get a proper keyboard to type (right now I'm typing on an iPhone while riding a bus to my workplace...). I' the proud manager for the new HECnet area 7.

I seem to remember that DECnet support now have been dropped from Linux. So it might not be in there anymore, if you look at recent versions. It's still there, at least in the new Ubuntu version (12.04). The routing support is not compiled in (it's marked as experimental) so you need to build the kernel if you want to try to use it as a router. I'm pretty sure it's a way to compile just de decnet modules instead of rebuilding all the kernel, but I don't know how to do it (I tried the obvious way and failed). I planned to use Linux as my area route. It does not work. If you configure it as a level 2 router it generates corrupted packets (they have 4 additional bytes at the header, it looks like it gets wrong some offset so it should be potentially easy to fix). It SEEMS to work as level 1 router and I was using it to link together multiple tap virtual devices... until I discovered the VDE support in the 3.9 version of SIMH and started using it to have all my emulated toys in the same Ethernet segment as all the real iron (VDE is cool, I recommend you to try it :)). Well, we'll either have to talk her into re-owning it (Hi Chrissie! 8-)) or someone else will have to take up its maintenance. At least eventually, when someone breaks the kernel networking APIs again. -Dave -- Dave McGuire, AK4HZ New Kensington, PA Jordi Guillaumes i Pons Barcelona - Catalunya - Europa BITXOV::JGUILLAUMES

(which I'm reaching from the aforementioned Linux machine!) It seems that off-net DECnet routing isn't happening from the Linux machine..? What's up with this, does anyone know?

I don't know of any .au on HECnet, so that would be cool... Let me know when you want to work on this, and I'll try to help from my end.

If not and you have some spare time this weekend, I'd love a bit of a hand getting initially one of my systems online. We have a 3 day weekend/long weekend so I'll have more time. I'll try building the newer version of the bridge.c on the SGI, but the old one appears to function. Ports are all still setup as per instructions.

As of today, there are 321 nodes in the nodename database. They are spread out over 16 areas. We have machines located on (at least) three continents, if I remember right. While not online all the time, I think we currently have atleast the following OSes represented: RSX RSTS/E VMS Ultrix Linux OSF/1 TOPS-10 Tops-20 Windows XP IOS If you know of any errors in this information, more fun facts, or anything else you'd like to share, feel free to do so.

So it might not be in there anymore, if you look at recent versions. I've also had less than stellar results from trying to talk from Linux to RSX. So it might not work absolutely right under all conditions. Developers mostly (it not only) had VMS machines to test against... It's been some years ago, but I did a bunch of work to make it talk well with RSTS/E. And I thought others had done the RSX work. What work was this? Right now file transfers are mostly non-functional with RSTS/E...transfers complete successfully, but line terminators are completely hosed, and no combination of command line switches will make them work properly. Incidentally, I can use Linux DECnet support to get files over to a VMS system, then copy them from THAT to RSTS/E via DECnet, and things seem ok. (at least I think that worked, the last time I tried it) I remember the rumor that it was dropped. Too bad. But there's no reason the older version couldn't be used, unless your chosen platform requires a later one. Having to keep another instance of Linux around just to "hop through" is certainly doable, but kind of a pain. :-( -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Multinet Tunnel Connections to SG1::

I'll look into it more tomorrow but I think it's similar to doing L3 on the 3560 or 4500/6500. Its L3 is limited to IP and it can't do tunnels, etc. I'll verify and report back. -brian On Jun 6, 2012, at 22:31, Dave McGuire <mcguire at neurotica.com> wrote: On 06/06/2012 10:11 PM, Joe Ferraro wrote: This isn't the thread for it, I realize.... the product slick states that the switch does BGP, HSRP, OSPF, VRRP, etc.. again, not my area of expertise... is this still considered a switch?

Supporting those dynamic routing protocols certainly suggests that it knows how to route! ;) Hey Brian, have you ever worked with those hybrid router/switch boxen? -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Um...that's a switch, not a router. I'm almost positive this model runs IOS, but as far as I'm aware it has no routing capabilities. But either way, free is good. :-) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
