Re: TOPS-20 on HECnet? - HECnet

16 Jan 2014

I have not written anything specifically to make it a GRE endpoint (if that is the right
term). It can work as a direct replacement for the bridge in that it can talk the same
protocols. In other words on a LAN it implements the DECnet Ethernet interface, and it
also accepts the UDP packet format processed by the bridge. The difference  being of
course that it does not bridge the networks, instead it routes between your local
Ethernet(s) and the "Ethernet" that comes in over the UDP interface.

I hope that explains it.

Does that work with GRE on Linux? I never got GRE with not IP to work on FreeBSD due to
strangeness with bpf.

Paul's python router talks GRE natively. Not sure how well tested that is though as I
never got it setup before the colo box getting shut off.

A GRE tunnel won't do much good if he can't route DECnet packets over it.

Is there a reasonable Linux DECnet router? If not, you may want to try out Paul's
python one.

   Oh ok.   I'm sorry, I misunderstood.

   I can set up a temporary GRE tunnel with you this afternoon if you
 like, until we can get you folded into Brian's tunnel configuration
 management system.   Let me know.

 Sorry if it wasn't clear... Two different threads had a little
 cross-posting I think.   Here I'm just trying to establish a solid
 HECnet peer.   Johnny-bridge would have been preferable since I'm
 running this on my NAS (and I know 'bridge' works), but if a GRE peer
 is easier to find, by all means.   While my QNAP NAS does have several
 tunneling options in its stock config (it's linux arm), it appears
 they did not include the ip_gre module, so I'll have to see about
 hacking that in.   Assuming that goes well, who's solidly offering the
 GRE tunnel?   We can exchange IP's and configs off-list.

 Thanks in advance,
 Mark
