Hi all,
I've just set up my net44 gateway using a Debian machine running in the
cloud with a static IP. My plan is to use this machine as an
IPIP-to-OpenVPN adapter so that I can run my subnet from home via my LTE
connection, with will not support IPIP. I set up the machine with Debian
linux and rip44d.
I'm currently receiving the routing table from 44.0.0.1, and I'm able to
ping several net44 machines in my area (44.4.2.153 and 44.4.50.1 for
example), however, my linux machine is not able to ping 44.0.0.1. At first
I assumed that this was a security policy, however, I'm also not able to
access the ampr.org website from that machine now. in addition, I'm unable
to ping my machine's net44 address from the internet.
Is this a result of gw.ampr.org not updating it's gateway list, and thus
not knowing how to route to me, or have I missed something obvious?
Also, if anyone with a properly maintained gateway list could ping me
at 44.4.36.1
and let me know the result, I'd appreciate it.
Thank you,
Blaine

Which means that the amprgw system has your gateway address and route ok,
and that you're receiving IPIP encapsulated packets from amprgw.

44.0.0.1 doesn't respond to pings from amprnet because of brokeness.
It's a bug in the kernel on amprgw which I've never been able to track down.

If you're receiving the routes, you're in the gateway list on gw.
It updates in real time when gateways changes are made on the portal.
I note that your gateway machine is not responding to pings from the
Internet on its commercial address. You might try running tcpdump on
your gateway system to see if pings from the Internet are reaching it
on either its commercial address or via IPIP on its AMPR address, and
to see if and how it is replying to those ping requests.

Ok, that solves that part of the mystery. I'm still curious as to why I
cannot get to the webpage however.

Well, that's very curious indeed. I just pinged my machine, and it
responded just fine for me.
$ ping ampr.k1qv.com

Not really sure what's going on here. As I said, I pinged
n6mef-gw.ampr.org(44.4.2.153)
as a test with tcpdump running. I see the IPIP encapsulated ICMP requests
and replies working as they should between my machine and his gateway...
So... we know that I'm receiving IPIP encapsulated traffic from 44.0.0.1
because I'm receiving the RIP traffic, however, tcpdump shows no inbound
traffic when trying to ping my 44.4.36.1 address from the internet.
Stupid question here, was I correct in assuming that my net44 subnet was
routable from the internet?

It is once you have a valid DNS entry associated with your gateway's IP:
n1uro@n1uro:~/ham$ host !$
host 44.4.36.1
Host 1.36.4.44.in-addr.arpa. not found: 3(NXDOMAIN)

Does your ampr host have an A record in the ampr.org DNS? If not it won't
be reachable from the internet even if the subnet is correctly routed.
There's a filter in amprgw that requires DNS entries for all hosts to be
reachable. The entire subnet is NOT reachable as a whole.

Ah!! I had a feeling I was missing something, but I didn't see that in
any of the documentation I was looking at.
My DNS request is still waiting for coordinator approval. I guess I'll
be waiting for that until I can finish off this first step of my
experiment.
Thanks for the help,

Does that mean that you submitted it via the portal.ampr.org DNS
function? I'm sorry, that function isn't working yet. I've asked
for it to be taken off the portal menu until it *is* working as it
confuses people.
Your address coordinator should submit a DNS update after he
assigned you your subnet and you give him the hostnames.
I can do that for you if needed.
- Brian

Yes, I did submit the DNS request via the portal. I wasn't aware that
it wasn't currently working.
Would it be possible for you to create a CNAME record for
k1qv.ampr.org. to point to ampr.k1qv.com.
If not, I can take an A name at 44.4.36.1
Thanks for the help with all this,

I can do either one, but they have vastly different meanings.
The first, for example, won't get you an A record in the AMPR.ORG
zone file, so there won't be a corresponding filter entry and
packets from the internet won't be routed to your 44.4.36.1
address.
Let me know what you want to do.

Well, it's going to make routing even more complicated on my end, but
I'll have to take the A name for the filter entry. Then I'll be on to
the next step of my great experiment!

New subject: AMRP DNS NS records?
I noticed that on AMPRNet portal DNS settings do not offer setting NS
records for domains. Whz is that?
I have full capable host and it can easily deal with DNS zone for domain
I choose. Al I need is to be able to set NS record to point to my host.
As it is not is too much hustle. First I have to manually maintain DNS
and then, my host assumes that if it hosts domain then it hosts DNS zone
too.

I didn't know that was not working and didn't know has to forward DNS
requests to you.
I'll have to go through my requests and update you.
Thanks.
