Dear fellow HECNETers
I?ve been using Johnnys bridge for a year or so, (thank you Johnny!) and wanted do some
additional networking.
Before going full gre peering is there anyone out there that could act as intermediate
peer to do some testing while I try not to break anything (!)
On my side I have good network connectivity, but unfortunately no static IP :/
The box I?m using is a 2610XM with ios ver 12.4
Happy if anyone is willing to share their connectivity

Dynamic IP and GRE is a problem. Even if you have a dynamic DNS service set up (I am using
duckdns.org's service happily for a while now if you need one), I don't know if
Cisco IOS does a DNS lookup every time it loses a GRE connection to the destination, or
even if a destination can be a domain name instead of an IP address. There are fabulous
GRE experts in this group who might chime in.
If the answer to all of the above is yes, and you are willing to move to area 31, I can
give you a GRE tunnel end point on Area 31.
The other alternative is a MULTINET connection to area 31 which also I can provide if you
wish. MULTINET is proven to be dynamic IP friendly.
Best,
Supratim

GRE tunnels can be built if one end is dynamic as long as your router supports multipoint
GRE (mGRE). Check and see if your router supports the command ?tunnel mode gre
multipoint? and that your tunnel supports commands that start with ?ip nhrp ?. If so,
then we should be able to set something up.

What is that, and how does it work? Accept GRE packets from any of a number of addresses,
and remember those to send back to them? The DECnet circuits would still be point to
point, unless the packet format changes to include the equivalent of an Ethernet MAC
address.

Thank you for all replies.
I've got area 33 as my own from Johnny so thats where hosts are
going til live when things are setup.
My ip is dynamic, but I've only got one change in a year. Hopefully I
will be able to change to static, but right now my isp only provides
dynamic. Changes are monitored and dynamically updates a dyndns
record.

Ok, I can set you up to talk to my router. If you want to do that,
send me your current IP address, and set up your GRE subsystem to peer
with 50.73.179.1. Just drop me an email if/when your IP address changes.

My bad.
I had it configured as L1 router. Changing config to "decnet node-type

pinging 61.2 works ok
pinging 61.3 gives Host unreachable
pinging 1.13 aka MIM times out
I will probably get back with more questions later on.
I have just node 33.200 and 33.201 up and running for the moment.

If you want, I will set up my router to accept dynamic GRE connections. Then, anyone with
a dynamic IP wanting to do GRE can connect to it.

New subject: Bridge vs tunnel
I?ve been running the bridge program for quite some time now and every time the tunnel
topic pops up I ask myself whether it would be better to move over as well.
I have a fixed public IP address, and have hecnet area 44 all for myself.
The bridge program and A44RTR (simh VAXserver 3900 VAX/VMS 6.1) run on an old laptop under
fedora v 21.
What do I need, in terms of software, hardware, to move to a tunnel?
My Cisco knowledge dates back to the Cisco MGS router (IOS 7) :-)

New subject: Bridge vs tunnel
If you have the Cisco hardware, my mesh system can configure it for you.
Although it didn't work right the last time and *really* needs to be
rewritten, but it'll at least send you the email of Cisco commands to copy
paste into the router.
You need to allow SNMP into the Cisco but you can limit that to only be
allowed from myst.platinum.net (199.166.5.172)
I need:
Your IP:
Is IP static:
hostname:
Source Interface: (this is the interface on the Cisco that the GRE
tunnel(s) are on)
Writable SNMP Community name:

move over as well.
I have a fixed public IP address, and have hecnet area 44 all for myself.
The bridge program and A44RTR (simh VAXserver 3900 VAX/VMS 6.1) run on an
old laptop under fedora v 21.
What do I need, in terms of software, hardware, to move to a tunnel?
My Cisco knowledge dates back to the Cisco MGS router (IOS 7) :-)

Ok, I am set up on my end. Anyone that wants to connect this way should set their tunnel
up as follows:
interface TunnelXX ! Whatever tunnel number you want to use
description DECnet mGRE tunnel
bandwidth nn ! Use a bandwidth value appropriate to your Internet connection
ip address 169.254.0.y 255.255.255.0 ! Where y = your DECnet area number
no ip redirects
ip mtu 1476
ip nhrp authentication HECnet!z
ip nhrp map multicast dynamic
ip nhrp map 169.254.0.27 70.89.171.10
ip nhrp map multicast 70.89.171.10
ip nhrp network-id 27
ip nhrp holdtime 3600
ip nhrp nhs 169.254.0.27
ip nhrp registration no-unique
ip tcp adjust-mss 1360
decnet cost 4 ! Or whatever cost you feel is appropriate
tunnel source <your internet-facing interface>
tunnel mode gre multipoint
tunnel key 99
end
You can test that the tunnel is up by attempting to ping 169.254.0.27 from your router.

Hello again
Thx Supratim and Dave for tunnel endpoints.
I now have managed to get a fixed address which hopefully will make it easier to connect.
Are there any endpoints in Europe that would be willing to share it's connection with
me at AREA34?
AREA34 is originating out of Stockholm Sweden.
@Dave McGuire, the new endpoint is 46.21.107.60 if you could change on your side.
@Mark Berryman, I'm now static if you're interested

Well, I (Update) have presence in Uppsala, including a Cisco router as
well as tbe bridge and Multinet. However, I prefer not to use the bridge
unless there are no other alternatives, as it's the best from a scaling
point of view.
Also, I already run a bunch of Multinet links. If I were to have more, I
would need to re-SYSGEN MIM, which I'm not to keen on right now. :-)

Incidentally, I'm a bit annoyed by Multinet configure rewriting decnet-circuits.com
and ruining the TCP-based connections set up. I've extracted out that part of the
setup to another procedure run in systartup_vms.com after multinet is started. I'm
going to make some changes to make sure it doesn't make use of any TCPAx: devices it
may already have configured though.

Keith - I'm starting to keep a list of people willing to peer, where
they are, and what methods they can deal with.
I'm adding you based on the info below. Let me know if you want out, of
if there is more I should know.

Hi Johnny,
That's fine by me.
In the cases where the other side has a fixed IP address, I would prefer to make the TCP
connection. I can keep my firewall rules simple and in failover situations my range of IP
addresses can change. Where the other side has a dynamic IP address, they'll obviously
have to initiate the TCP connection but I can at least limit acceptable incoming IP
addresses down to a range.
Does anybody have any experience of running DECnet circuits over Multinet's (default)
UDP configurations?
Keith

Yes, in tests at least. It's not a good solution. The reason is that Multinet is,
from the DECnet point of view, a "point to point datalink" and the DECnet
requirements for such a link are NOT satisfied by Multinet over UDP. In other words, to
put it bluntly, Multinet over UDP is a DECnet protocol violation.
With a bit of luck and patience the connection typically does come up and can be used.
But if you want something that's reliable, better choices are (a) Multinet over TCP,
(b) GRE, (c) DDCMP (as implemented by SIMH). (b) and (c) at least clearly obey the
architectural requirements, and (a) either does or is close enough to be reasonable.

Hi Tony,
I am in Perth, Western Australia (area 12). If you are interested, you can
also create a GRE pipe to my router. My public IP is 110.141.227.104.
Let me know if you want to set it up and I'll poke the relevant holes in my
ASA.
Regards, Tim.

I'll gladly help if you can work out the dynamic IP address problem.
Or I can do it if it doesn't change very often.
