Back to the problem in hand. Any ideas?
Can ping you 12.1023 and 12.2 from the router which is good; can ping 22.10 from the router which is also good; but for some reason i cannot connect from VAX (22.10) on FastEthernet0/1 to 12.2.
This must be a local issue.
Is there anything else I need to setup above what I have for FE0/1 and decnet on my router?
decnet routing 22.100
decnet node-type area
interface FastEthernet0/1
ip address 10.22.1.254 255.255.255.0
speed auto
full-duplex
lat enabled
decnet cost 4
and my tunnel to you which I don t think is the problem
interface Tunnel57
description HECnet tunnel for Tim Sneddon (Area 12) [Version:274]
no ip address
decnet cost 20
tunnel source FastEthernet0/1
tunnel destination 120.146.225.243
tunnel path-mtu-discovery

It would be nice to move the connection off a Linux box to a VMS system.
There is a libpcap version for VMS, it's used by simh.
The problem is Python. AFAIK that i s just v2.7 for VMS. I know my systems run that kit, but I don't use it much so a newer version may be available.

The Python 3.3 what s new document says that VMS is no longer supported due to lack of a maintainer . So it may be possible to build Python 3.2 on VMS. The current DECnet/Python code wants 3.3, but earlier on I used 3.2 and there isn t much that needs 3.3. (In other words, it would not be all that hard to change it back to allow 3.2.)

Probably not, at least not without some changes.
It typically runs as a daemon, and on VMS that s done differently. Also, it uses libpcap via the Python ctypes module. Is there a VMS port of libpcap? Even if yes, the details of what symbols you ask for in the ctypes wrapper for that library might be different.
Finally, it uses Python 3, so you d have to have that; Python 2 won t do.
It would be seriously neat if this can be made to work, though.

Ah. Cool. I wasn't sure if it would also bridge other protocols, since
these are not related to DECnet as such.
One can tunnel most anything over GRE, even raw Ethernet frames,
regardless of the higher-level protocols. Hence the 'G' for "Generic".

Sorry guys - late to the party (West coast time zone and only a day after New Year - I was still sleeping). Did I see mention of a problem with the HUB:: tunnels, or did that get resolved? Let me know if the box needs a reboot.

It scales better and use less network bandwidth, if that is a concern.
Less network bandwidth because the GRE tunnel doesn t use Ethernet padding and regular Ethernet headers, while the JB bridge is a bridge so it does have both of those?
That seems like the only difference; from the DECnet routing layer point of view, both are LAN links and the protocol operation is the same for both.
FWIW, my Python based router includes GRE tunneling, and while I would not claim it is totally production grade code yet, it s in good enough shape that it might be interesting for one or two enterprising folks to try that approach. A useful property vs. Cisco boxes is the cost (free).

What exactly do you mean by "it scales better" ?
Less bandwidth load on the Internet line, in my case 12 Mb/s ADSL.
Or less load on th local decent hosts?
The first would persuade me, easily.

But it won't pass through LAT or MOP. Pick your poison. :-)
