-====== Allstar : Explorations ======
-** Digging Deeper into Allstar **
-I've seen a few examples of small networks and am interested in building up a mixed protocol system too.
-Some examples that interested me:
-  * Milnet [[http://milnet.io/]] with Allstar connected nodes and a DMR bridge
-    * Allstar node status [[http://stats.allstarlink.org/nodeinfo.cgi?node=424611]]
-  * W2YMM [[https://w2ymm.home.blog/allstar-howto/]] with a group of connected gateways, repeaters and a bridge to DMR etc.
-    * This one was discovered by accident on Allstar's Portal I mistyped my own original base node ID (pre-NNX) **48148** as [[http://stats.allstarlink.org/nodeinfo.cgi?node=48418 | 48418]] and found his system with lots of information on his blog
-===== Adding more nodes =====
-{{ :public:radio:2025:networkmap_2_.jpg?direct&600 |}}
-It's possible to have up to 10 individual Node IDs with a single Allstar node number, by using NNX to add a 6th digit to the base node number...
-My Base Number is ''48148'' and I activated the ''NNX'' feature and created 3 nodes
-  * ''481480''
-  * ''481481''
-  * ''481482''
-Since they are all behind a NAT firewall, sharing one public IP address the nodes must use different UDP ports. To make this possible I created 2 new ''Server'' instances on the Allstar Portal, one per node, and chose the UDP ports :
-[[https://www.allstarlink.org/portal/servers.php]]
-  * ''node481480'' => ''UDP 4569''
-  * ''node481481'' => ''UDP 4570''
-  * ''node481482'' => ''UDP 4571''
-The choice of which server is used per node is chosen on the Node configuration page for each node, on the Allstar Portal
-[[https://www.allstarlink.org/portal/nodes.php]]
-Then I flashed new SD cards for the new nodes using the ASL 2.0.0 Beta 6 image I've used for the initial VHF Gateway node.
-[[https://github.com/AllStarLink/ASL-Live-Build/releases/download/2.0.0-beta.6/asl-2.0.0-beta.6-kc1kcc-20210324-raspberrypi-armhf.img.zip]]
-The config. for the original node had to be changed, to reflect the new node number ''481480'' versus ''48148'' which means editing (at least)
-  * ''/etc/asterisk/rpt.conf''
-  * ''/etc/asterisk/iax.conf''
-  * ''/etc/asterisk.extensions.conf''
-To ensure each internal LAN node can find each other (can't rely on Allstar's DNS) it's necessary to add each one to the ''[nodes]'' stanza in each node's config file ''/etc/asterisk/rpt.conf'' using the appropriate IP and UDP port depending on which node is being configured.
-<code>
-; from the VHF Gateway node 481480
-[nodes]
-= radio@127.0.0.1:4569/481480,NONE
-= radio@192.168.21.241:4570/481481,NONE
-= radio@192.168.21.242:4571/481482,NONE
-</code>
-I added the DVSwitch bridging to the hub node ''481481'' which is configured as //radioless//, I made a local/private node on that machine ''1399'' for this purpose.
-All 3 nodes have ''supermon'' and this needed some configuration to make sure the Asterisk Manager ports were available on their external interfaces ''bindaddr = 0.0.0.0'' and not just on the loopback ''bindaddr = 127.0.0.1''
-''/etc/asterisk/manager.conf'' =>
-<code>
-;
-; Asterisk Call Management support
-;
-; By default asterisk will listen on localhost only.
-[general]
-enabled = yes
-port = 5038
-bindaddr = 0.0.0.0
-[admin]
-secret = YOUR_MANAGER_PASSWORD
-read = all,system,call,log,verbose,command,agent,user,config
-write = all,system,call,log,verbose,command,agent,user,config
-</code>
-==== Port Forwarding ====
-My ADSL router has the following port forwards to allow external incoming connections to be set up
-  * ''UDP 4569'' => ''192.168.21.240'' for the VHF Gateway / Echolink node
-  * ''UDP 4570'' => ''192.168.21.241'' for the DMR Bridge node
-  * ''UDP 4571'' => ''192.168.21.242'' for the Test Node
-  * ''UDP 5198-5199'' => ''192.168.21.240'' for Echolink client connections
-  * ''TCP 42110'' => ''192.168.21.240'' for the VHF Gateway/Echolink node's Dashboard
-    * [[http://gm4slv.plus.com:42110]]
-  * ''TCP 42111'' => ''192.168.21.241'' for the DMR Bridge node's Dashboard
-    * [[http://gm4slv.plus.com:42111]]
-  * ''TCP 42112'' => ''192.168.21.242'' for the Test node's Dashboard
-    * [[http://gm4slv.plus.com:42112]]
-To allow the node numbers to be resolved to useful names tp display on the dashboards the script ''astdb.php'' should run nightly to maintain a lookup table.
-The image came with several copies of ''astdb.php'' in different places, all updating a central data file ''/var/log/asterisk/astdb.txt''. Which was confusing, as they all looked in different places for the file detailing private nodes.
-==== Private Node Names ====
-To allow private node numbers to appear as useful information, rather than ''not in database'' you first put the information in a file ''privatenodes.txt''
-<code>
-|GM4SLV|Bridge to DMR|TGIF TG2354429
-|GM4SLV|Bridge to DMR|TGIF TG2354435
-</code>
-and then the ''astdb.php'' script pulls it in, with all the other nodes downloaded from the web, but ''astdb.php'' must know where to find the ''privatenodes.txt'' file.
-The easiest way is to run the ''astdb.php'' from the directory containing ''privatenodes.txt''
-and therefore it's the copy in ''/var/www/html/supermon/'' that is used, since ''privatenodes.txt'' resides here too.
-To automate the process the update is done nightly via ''/etc/cron.daily/allstar_helpers'' which was modified to point to the correct version of ''astdb.php''
-<code bash>
-#!/bin/bash
-# Get new allmon data daily
-/var/www/html/supermon/astdb.php
-</code>
-=== Semi-automated Private Node descriptions ===
-  * I've written a small bash script on the gateway node481480.local to make it easier to re-name the internal //"private nodes"// as they appear listed in Supermon
-  * for this to work it's necessary to arrange public-key authentication on the nodes, with passwordless logins. But that's normal, anyway, no?
-<code bash>
-#!/bin/bash
-# update_private.sh
-# a script to distribute new copies of privatenodes.txt and run the astdb.php update script
-#NODE1=node481480.local
-NODE2=node481481.local
-NODE3=node481482.local
-PRIVATE_NODES=/home/gm4slv/privatenodes.txt
-sudo cp $PRIVATE_NODES /var/www/html/supermon/
-sudo /var/www/html/supermon/astdb.php
-scp $PRIVATE_NODES gm4slv@$NODE2:
-ssh $NODE2 'sudo cp /home/gm4slv/privatenodes.txt /var/www/html/supermon/ && /var/www/html/supermon/astdb.php'
-scp $PRIVATE_NODES gm4slv@$NODE3:
-ssh $NODE3 'sudo cp /home/gm4slv/privatenodes.txt /var/www/html/supermon/ && /var/www/html/supermon/astdb.php'
-</code>
-  * Just make changes to the ''privatenodes.txt'' file in my local directory on the gateway ''node481480'' and then run
-<code bash>
-gm4slv@node481480:~$ ./update_private.sh
-Success: astdb.txt 1422647 bytes
-privatenodes.txt                              100%   79    39.0KB/s   00:00

-==== Supermon ====
-The nodes monitored, and the menu to select them, and external websites, on each node's Supermon Dashboard is configured by ''allmon.ini''
-Here's the current version:
-++++ Generic /var/www/html/supermon/allmon.ini |

-==== Node Callsigns instead of Numbers ====
-To have the telemetry say the //callsign// of a connected node, instead of its //node number//, install the script ''write_node_callsigns_ulaw.sh''
-I put it in ''/usr/local/bin/'' and run it via root's crontab each day - but via a wrapper script  ''/usr/local/bin/update_names.sh'' that then deletes the ulaw sound file for my own nodes, as I don't want all of them to be announced as ''GM4SLV'' - I'd rather hear the actual node numbers:
-<code bash>
-#!/bin/bash
-/usr/local/bin/write_node_callsigns_ulaw.sh
-rm /var/lib/asterisk/sounds/rpt/nodenames/481480.ulaw
-rm /var/lib/asterisk/sounds/rpt/nodenames/481481.ulaw
-rm /var/lib/asterisk/sounds/rpt/nodenames/1399.ulaw
-rm /var/lib/asterisk/sounds/rpt/nodenames/1398.ulaw
-rm /var/lib/asterisk/sounds/rpt/nodenames/48148.ulaw
-rm /var/lib/asterisk/sounds/rpt/nodenames/481482.ulaw

-The initial node, described here : [[gm4slv_allstar_2025|]] got too cumbersome adding DMR Bridging, along with handling Echolink.
-I decided, since I had a few spare Raspberry Pi boards doing nothing much, to split the DMR Bridging to a separate node.
-I removed the DVSwitch bridging from the VHF Gateway node.
