I'm not seeing any changes to the RIP broadcasts (seems to be stuck at
843 lines for last couple of days).
Also can't download encap file from portal.ampr.org/api/v1/encap (should
existing API key still work?)

I have previously recorded malicious traffic in the past. It was from a rogue gateway. The endpoint was simply dropped from our RIP44 statements.To Charles' point - the traffic was firewalled, it's that alert which brought it to my knowledge. It also reiterates the need for RFC-documented methods to ensure we don't have stale records.- KB3VWG

All,
How do I email the new Wiki Group - as changes have been made by an Admin?
(FYI - I joined them)
While the edits are "OK", they are "grammatical" in nature, and the last edit sparked distinction (funny the discussion was regarding recursive DNS servers).
There are superseding edits after I [finally] removed the SK from the Wiki. I asked about this after the passing of Brian R. - but I was told to be patient by my coordinator,

Hi there,
I would like to rewrite or add my DNS entry for ampr.org.
I'd requested via the new portal as a Ticket, but still unassigned.
I think I must have the authority to modify it.
Can anyone help me ?
regards,
Toshiyuki JF3LGC

Hi Kun,
The RIP broadcasts are sent as encapsulated multicast packets over the tunnel from the UCSD gateway server on 44.0.0.1 to your tunnel endpoint, so you need the tunnel setup before RIP44d can receive these broadcasts.
I am assuming you are using some flavour of Linux as your gateway machine, if so as a minimum you would need to:
modprobe ipip
ip addr add 44.x.x.x dev tunl0
ip link set dev tunl0 up
where 44.x.x.x is your tunnel endpoint IP.
Then you can run the find_pass.sh script, which is just a one liner:
ampr-ripd -d -v -i tunl0
I use Debian 12 and this is how I have my gateway setup, hope it helps...
I use systemd to start everything up automatically after a reboot: /etc/systemd/system/amprgw.service
[Unit]
Description=AMPRNet
After=network-online.target
Wants=network-online.target
[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/usr/local/bin/ampr_start.sh
ExecStop=/usr/local/bin/ampr_stop.sh
[Install]
WantedBy=multi-user.target
After creating this file you need to run “systemctl daemon-reload” followed by “systemctl enable amprgw” and “systemctl start amprgw”
Here is the ampr_start.sh script:
#!/bin/sh
PWD=“<the RIP44d password>"
LOCATION="G1FEF@IO91mk"
AMPR_OUR_LAN="44.63.7.208/29"
AMPR_OUR_TUN="44.63.7.215"
EXT_INTERFACE="enp1s0"
INT_INTERFACE="enp2s0"
TUN_INTERFACE="tunl0"
# Enable IP Forwarding
sysctl -w net.ipv4.ip_forward=1
# Enable IPIP tunnel and interface
modprobe ipip
ip addr add $AMPR_OUR_TUN dev $TUN_INTERFACE
# Set some tunnel interface options
# * Give the tunnel its own TTL of 64 hops enabling traceroute over the tunnel
# * Bring up the interface
# * Set the tunnel MTU
ip tunnel change ttl 64 mode ipip $TUN_INTERFACE
ip link set dev $TUN_INTERFACE up
ifconfig $TUN_INTERFACE mtu 1480
# Set AMPRNet routing table rules
# * Any packets from any AMPRNet space use routing table 44
# * Any packets from my AMPRNet space use routing table 44
ip rule add to 44.0.0.0/9 table 44 priority 44
ip rule add to 44.128.0.0/10 table 44 priority 44
ip rule add from $AMPR_OUR_LAN table 44 priority 45
# Set AMPRNet routes
# * Default route out of AMPRNet is 169.228.34.84
# * Set local route for AMPRNet on local AMPRNet interface
ip route add default dev $TUN_INTERFACE via 169.228.34.84 onlink table 44
ip route add $AMPR_OUR_LAN dev $INT_INTERFACE table 44
# Rest of the routes are added dynamically by the AMPR-RIPD routing Daemon.
/usr/sbin/ampr-ripd -s -r -t 44 -i $TUN_INTERFACE -a $AMPR_OUR_LAN -p $PWD -L $LOCATION
and the ampr_stop.sh script
#!/bin/bash
NET_AMP="44.63.7.208/29"
NIC_AMP="enp2s0.44"
NIC_TUN="tunl0"
### DISABLE IP FORWARDING ###
sysctl -w net.ipv4.ip_forward=0
### Take the tunnel offline ###
ifconfig $NIC_TUN down
### Remove the table 44 routes ###
ip route delete default dev $NIC_TUN via 169.228.34.84 onlink table 44
# Deletes local 44 network from Table 44
#ip route delete $NET_AMP dev $NIC_AMP table 44
### STOPS THE ampr-ripd ROUTER DAMEON
killall -KILL ampr-ripd

Charles,On April 6, Chris noted to me that 44.00.0.1 would stop having nameserver functionality in the future. This is a concern, as I don't know of another Authoritative Name Server for AMPR.ORG and 44.in-addr.arpa capable of Zone Transfer.Despite this, I have not yet been given an updated AMPRNet nameserver to reconfigure DNS-MDC.AMPR.ORG before that decommissioning.73,LynwoodKB3VWG

I just received email and then a phone call from a person that wanted
to join one of our networks in the Northeast USA for the purposes of
routing Echolink, repeaters and more. When logging onto the "new" AMPR
portal, they were given only a choice of a few subnets based on a dropdown
list of intended uses. None of them jived with the networks in any of
the individual states or countries. I would suggest spreading the word
that all requests for new or expanded allocations be held up until things
can be straightened out. It seems that their small volunteer force is
unable to keep up with the workload since the changeover on April 3rd.
I personally have over a dozen tickets unassigned and even one from 4/3.
Everyone just standby and chill until they figure things out. No need
to expect steak when they are working with hamburger.
I just jumped on the AMPR portal and found only these choices:
IPIP Tunnel Mesh 44.63.0.0/16
BGP Direct Announce 44.32.0.0/16
Radio 44.61.0.0/16
Globally Unique 44.61.0.0/16
General Address 44.61.0.0/16
