Oh, when I run find_pass.sh again, I did get the ripv4 broadcast and found the password.
And then I proceed to setup rc.local as documented in that wiki article. However, I still can't ping my AMPR IP from Internet.
-- rc.local
### ## Create AMPRNet Tunnel and routing ##
## Configure Tunnel (put your ISP you received from your ISP Here). ip tunnel add ampr0 mode ipip local 209.141.42.9 ttl 255
## Bring it up ip link set dev ampr0 up
## Enable Multicast in order to receive routes ifconfig ampr0 multicast
## Configure Policy Based routing # Packets to 44/8 network use routing table 44 ip rule add to 44.0.0.0/8 table 44 priority 44
# Packets from our 44 subnet use table 44 (put your AMPRNet Subnet here) ip rule add from 44.26.0.168/29 table 44 priority 45
## Configure static routes # Default route for table 44 is to send traffic to amprnet gateway at UCSD ip route add default dev ampr0 via 169.228.34.84 onlink table 44
# Route packets for our net to local interface (put your AMPRNet Subnet here) ip route add 44.26.0.168/29 dev ens3 table 44
## Start ampr-ripd to learn rest of mesh routes # Be sure to substitute the password you found earlier for <SecretPassword> # Put your static IP you received from your ISP here. /usr/bin/ampr-ripd -s -i ampr0 -a 209.141.42.9 -t 44 -p <thepassword I received>

I have configured the public IP in the AMPR portal as gateway.
If you just did this, wait a while like a half hour.
When I try to run find_password.sh in ampr-ripd-2.4, I am stopped at Waiting for RIPv2 broadcasts... and never retrieve a password.
You don't need to run the find password script or specify a password if you are using ampr-ripd above version 1.14 (its hardcoded in the program). But I do believe even if you run that, it should retrieve it.
I usually start off really stripped down, with all firewall stuff off till I know I am receiving the protocol 4 rip broadcasts.
Do you see anything with tcpdump ? tcpdump -i eth0 -vvv host amprgw.ucsd.edu or ip proto \icmp
If not, then something upstream is blocking protocol 4 from reaching you. Seems like it might be outside of your home if your configuring the interface directly with a public IP
In the iptables world, here is the ipencap (protocol 4) syntax: iptables -A INPUT -p 4 -j ACCEPT

I have been trying to configure the AMPRtunnel for a while without success. Could someone please point me to the right direction.
I am running Debian 11 with public IP. I have configured the public IP in the AMPR portal as gateway.
I am trying to follow this document https://wiki.ampr.org/wiki/Ubuntu_Linux_Gateway_Example
When I try to run find_password.sh in ampr-ripd-2.4, I am stopped at Waiting for RIPv2 broadcasts... and never retrieve a password.
Here is what I have done so far.
in /etc/network/interfaces, I added
auto ens3:1 iface ens3:1 inet static address 44.26.0.168 netmask 255.255.255.248
Then I created ipip tunnel using following commands
ip tunnel add ampr0 mode ipip local 209.141.42.9 ttl 255 ip link set dev ampr0 up ifconfig ampr0 multicast ip rule add to 44.0.0.0/8 table 44 priority 44 ip rule add from 44.26.0.168/29 table 44 priority 45 ip route add default dev ampr0 via 169.228.34.84 onlink table 44 ip route add 44.26.0.168/29 dev ens3 table 44
Then, I run ampr-ripd -d -v -i ens3 to get the password in order to plug into lat command ampr-ripd -s -i ampr0 -a 209.141.42.9-t 44 -p <SecretPassword>
However, the find_password.sh stopped at waiting for ripv2 broadcast. Here is the logs for command
Using metric 0 for routes. Using TCP window 840 for routes. Using gateway 209.141.42.1 for direct 44net endpoints via interface ens3. Waiting for RIPv2 broadcasts...
Any idea on what am I doing wrong? Thanks
