[arm-allstar] node connections

[Doug Crompton]

I guess I should do a how-to on this since this question gets asked so often!

When connecting nodes they need both the information to connect and the path to connect. The information to connect is found either in the rpt_extnodes file (in /tmp on the RPi2 and BBB and /var/lib/asterisk in Acid) or in a specific path entered in your rpt.conf file under the [nodes] stanza.

To check use grep on the database or view the nodes section in rpt.conf

grep 42285 /tmp/rpt_extnodes

grep 28302 /tmp/rpt_extnodes
28302=radio at 50.93.230.87:4569/28302,50.93.230.87
As you can see one node turned up an address the other did not here this morning but perhaps the 42285 node is off the air. 

Nodes have to have routing information at BOTH ends to work. This includes the IP address AND proper port. Often ports are the issue because people do not specify them if they are different then the default 4569. The port must be defined in the local ( [nodes] stanza ) information if it is different than the default.

The master database ( rpt_extnodes ) is usually used to determine how to get to another node but for local or private connections it is often specifically defined in the rpt.conf [nodes] stanza. 

You can use the Asterisk client  (asterisk -rvvv at the Linux prompt) to troubleshoot this as it gives messages at BOTH ends about what went wrong. If you connect from one node to another and you do not see any messages at the node you are connecting to then it did not get through and you can suspect a routing problem due to a misaddress or port either in the database or port forwarding if it is outside your LAN. Of course outside your LAN it could also be a hopefully temporary Internet routing problem beyond your control.

Subject: [arm-allstar] node connections

I have put two new nodes on line and all is working great. Yesterday my 42285 node  stopped being able to connect  to the reset of my nodes 2351,2578,28302. Butit can connect to any other node that's on line. 
2351,2578,28302 cannot connect to 42285 but they all will connect to any other nodes on line.This is strange behavior and not understanding why this is happening. 
2351,2578,28302 all live on one RPI2 and on its own IP at my repeater site. 42285 is on an ACID install P4 computer at my home qth and its own IP. Port 4569 is forward correctlyon both routers as they all will connect to other nodes on line. Both IP address at my repeatersite and at my home are from the same provider.
