tunnel window settings
by marius＠yo2loj.ro 08 Jun '17

08 Jun '17

I was wondering if the usual TCP window setting of 840 makes any sense in our current mesh. This setting was imposed by the assumption that our IP traffic will pass over ax.25 connections, with their MTU and ACK limitations, and does not affect AXIP, AXUDP or other transfer modes. The question is: Is there anyone forwarding TCP/IP over AX.25 at this moment? Because if not, we could drop that window setting in the routing daemons and get a more streamlined data flow.

AMPRNet DNS robot
by Brian Kantor 07 Jun '17

07 Jun '17

I'm planning on making some changes to the AMPRNet DNS robot that will significantly alter the transaction response format. It will still be human readable, but if you are analyzing the responses using software of some kind, you'll have some work ahead of you. How many of you who use the robot are using software to handle the responses? - Brian

AmprNAT
by Brian 07 Jun '17

07 Jun '17

I have finished documenting and putting up on my website what I call AmprNAT. For those who attempting to get out via amprgate sourcing as their lan IPs, this not only will prevent this from occurring but also it will NAT you out as your gateway's IP... pending you're using a distro of linux. It requires a static route in your route pointing to your gateway, and then 3 lines of iptables rules. You may read about it at: https://n1uro.ampr.org/linuxconf/44nat.html I believe Lynwood is adding info on the wiki for this. -- I was reading a book about the history of glue... I couldn't put it down. ...think about it... -------- 73 de Brian - N1URO/AFT1BR email: (see above) Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode http://uronode.sourceforge.net http://axmail.sourceforge.net AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, Pennsylvania, Rhode Island, and Vermont.

Reminder about Amprd for simple configurations
by Marius Petrescu 07 Jun '17

07 Jun '17

Hi, Since everyone seems to like to use the most unusual script with "original" settings without trying ever to understand what's happening, I would remind you that there is a more or less "plug-and-play" solution called amprd... Let's assume a system with: - 44net assignment: 44.128.1.0/24 - WAN on eth0 (let's assume 1.2.3.4) - LAN on eth0 (192.168.1.1/24) - AMPR on eth2 (44.128.1.0/24) - We choose our GW IP to be 44.128.1.1 and that the internet access from the system is already set up, with NAT and default gateway via WAN. Now: 1. compile (make) and install (make install) amprd 2. create the following /etc/amprd.cfg: ----------------------------------------------------------------- [ampr0] prefix = 44.128.1.1 rip_receive = yes rip_save = yes ----------------------------------------------------------------- 3. Set address 44.128.1.1/24 to your eth2 interface 4. Start amprd. And basically that's it: a fully functional mesh gateway. If you want access from the internet to your subnet, too, instead of just starting amprd, create the following ampr startup script: ----------------------------------------------------------------- amprd ip route add default via 169.228.34.84 dev ampr0 onlink table default ip rule add from 44.128.1.1 table default ip rule add from 44.128.1.1 to 44.128.1.0/24 table main ----------------------------------------------------------------- This should do the trick.

Portal IP hasn't changed in a few hours
by lleachii＠aol.com 07 Jun '17

07 Jun '17

All, Once again, my WAN IP and Subnet changed (about 5 hours ago now). I did reboot my GW; but my IP has not yet changed in the portal and I cannot reach other 44subnets or the Internet. I have logged in the Portal, removed the IP from the GW webform and hit save (leaving only the DDNS hostname). - Lynwood KB3VWG

Ampr-ripd experimental 2.3 version
by Marius Petrescu 05 Jun '17

05 Jun '17

Hello everyone, Since experimenting goes one, here a new ampr-ripd version that forces the sending of call home data to use the tunnel's IP as its source IP address. Tnx. Lynwood for pointing out that necessity. Interactive map which is available at http://yo2tm.ampr.org/ampr-map/ For those that do not want to participate, there is no need to upgrade. And even if you do, not setting the -L parameter will not send any data, the result being the same behavior like 2.1.1. Download: http://www.yo2loj.ro/hamprojects/ampr-ripd-2.3.tgz http://yo2tm.ampr.org/hamprojects/ampr-ripd-2.3.tgz Have fun, Marius, YO2LOJ
