Hi list,
I'm trying to get a mikrotik RB2011 connected to AMPRGW but not having
success.
/ip route check 44.0.0.1
status: ok
interface: ampr-gw
nexthop: 44.0.0.1
/tool traceroute 44.0.0.1
# ADDRESS LOSS SENT LAST AVG BEST
WORST STD-DEV
STATUS
1 44.34.128.1 0% 2 0.5ms 0.5 0.5
0.5 0 host unreachable from
44.34.128.1
2 0% 0 0ms
Using the sniffer, I've tried to also ping my address (44.34.128.1) from
the outside, but it does not get through. In addition, pinging 44.0.0.1
from the router fails as well (tracert shown above). I do however see a
discovery attempt going out and not getting any response back.
/tool sniffer quick interface=ampr-gw
INTERFACE TIME NUM DIR SRC-MAC DST-MAC VLAN
SRC-ADDRESS DST-ADDRESS
PROTOCOL SIZE
ampr-gw 33.3 1 ->
44.34.128.1:5678 (discovery) 255.255.255.255:5678 (discovery)
ip:udp 114
I do have an IPIP interface to the edge router for 44.24.240.0/20, and that
is operating properly; I can access their network, and they can access
mine. So, I'm a bit puzzled by this.
My config amprgw:
/interface ipip
add local-address=99.173.137.24 name=ampr-gw remote-address=169.228.66.251
/ip route
add distance=1 dst-address=44.0.0.0/8 gateway=ampr-gw
Any help is greatly appreciated!

This, i've got it going, but requiring a mesh of tunnels is nasty and it's
hard to maintain (absent custom protocols)
As it stands now, my BGP space can talk to the rest of the internet, but no
other 44/8 (excluding the 9 BGP subnets).
I'd love to write up an draft proposal for AMPRnet on how to fix this, but I
just don't have the time right now. I'd want it as a standard that works on
all routers at least for the "core". Perhaps even a route reflector software
would work (ALU/CSCO/JNPR have this now). Even foundcade would work, the
MLX's don't shit the bed anymore :)
Mikrotik is not something you can put in a CO/datacenter for obvious reasons.
I'd love to say we need a custom protocol, but the chances of getting that
supported on anything production grade is slim to none.
Argh, I'll have to make time to do this. I travel about 75% of the time for
work, it sucks. I'm a bit hungover in an airport now even :)

Yes thats correct. Why do you think an unreliable gateway is the proper
way to build a network?
If that subnet needs failover, then add failover.

No, it's a volunteer effort that's broken, because everyone wants to
over-engineer some new unduly-complicated idea into a very uncomplicated
system that actually works REALLY WELL EVERYWHERE else..

This mesh crap really needs to be binned, or at the very least not try and
do anything important over it, such as route an entire /16. If you want to
connect a /24 with it to make a neat local play toy then go for it, but
using it as an enterprise routing tool is absurd at the very least, and at
it's WORST, it's very likely to just completely stop anyone from trying to
build anything new over it because it's connectivity and throughput sucks.
It's just a subnet for gods sake - stop playing with it and route the shit
already, then we might actually get to DO SOMETHING over it. Puhleeease..

is there a written spec for exactly what the amprnet portal needs to

Brian,
Interesting, thanks for sharing.
Amplifiers are something I really think the ham community needs to think about.
They exist, but like you say, but at outrageous prices. i.e.:
http://www.shireeninc.com/300-500mhz-20-watts-outdoor-amplifier/
I have been reading Dubus magazine (focused on microwave), hoping to
read more data oriented construction articles.
I am much in the same line of thinking. 1200 and 9600 is really not
worth re-deploying in 2014. The regulatory landscape needs some major
changes so that manufactures can put something different in the hands
of many.

My segment 44.98.254.0/24 is being used for one PtP data link now, and some
asterisk based repeater controllers.
I have email for kb9mci.net on it (but need to get SWIP/PTR going Brian ;).
My intent is to fire up some of the doodle labs 23cm link cards as we get
another repeater site and link it over on that space. As this grows over the
next couple years it will be quite a high speed data network with VoIP as the
primary purpose. Doing all the RF links in the ham bands is part of the fun.
(anyone have a OFDM rated 20-30 watt amp for 23cm that's not $2k?)
One of the pet peeves I've have is not being able to access the other AMPR net
space with out tunnels. I think tunnels are just an ugly hack IMO. I'd like
to see us transition into more of a regionally routed network, rather than the
few BGP nets and UCSD gateway. Well aware of how much time this would take
I'm not ready to write up a proposal just yet (ampRFC?).
If anyone wants a subnet I'd be happy to route it to you, as I'm not using the
whole /24 and won't be for some time. Global routing policies being what they
are, a /24 is the smallest subnet you can announce.
My interest lies in high speed networks, and see little to no value in 9600
baud IP networks in 2014 :)

Along the same lines, I have been wondering:
Will the portal design/code be available for other regional BGP
enabled 44net gateways to implement?
It would be interesting to hear more about how those other BGP
announced chunks of 44net are using the space.
For a quite a while I've been getting "bugs in scheduling while atomic" kernel
messages.
I seem to recall there were some issues with SMP and mkiss at some point in
the past.
This isn't a hardware problem since the issue remains after putting together a
completely new system.
This is currently a machine running debian wheezy i386 userland with a x86_64
kernel.
ax25_rebuild_header is in all of these dumps. Seems suspicious.
The hardware is a i7-4770K CPU @ 3.50GHz with 16 gigs of ram, dual ethernet
ports (acting as a router), a serial kiss port to a TNC and an AXIP port.
ham related modules in use:
ipip 12941 0
tunnel4 12629 1 ipip
ip_tunnel 21436 1 ipip
netrom 36534 4
mkiss 17161 2

Hi,
I've checked DNS A records for various hosts in the net that I'm
co-ordinator for and they resolve but to to obsolete records. I've
entered some new records via portal.ampr.org, expecting them to come to
me for approval but as yet, no email!
The correct entries should be -
gw.g4irx.ampr.org IN A 44.131.56.9
g4irx.ampr.org IN A 44.131.56.10
Ideally the entire 44.131.56.0/24 block could be deleted as we've
started afresh re-allocating addresses.
Any suggestions to get this fixed?
Thanks,
Nick G4IRX.
