Nodes connected to each other WITHOUT allstar "server'?

App_rpt-users
1

The way I understand it …
when any node connects to another it is “through” an allstar server.
As I\m not 100% sure about this, can someone please explain.
Is ALL the traffic handled by a server, or does the server just
tell the nodes how to find each other (DNS) ?
IF all the traffic goes through the server ( another Asterisk in the “sky”),
how can I connect two nodes to each other without an Allstar server.
ie, “order wire” for (interoffice communication) .
Direct IP to IP address ??

Thanks

Don,

Connecting two nodes together on a private network is actually pretty easy.

What you will need to do is add the node and IP address of the other node(s) to each servers rpt.conf in the [nodes] stanza.

Here’s an example with two nodes on a private network.

Server A’ s IP is 192.168.1.10 and B is 192.168.1.11.

SERVER A rpt.conf

[nodes]

1000 = radio@127.0.0.1/1000,NONE ; Local node

1001 = radio@192.168.1.11/1001,NONE ; Remote node

SERVER B rpt.conf

[nodes]

1001 = radio@127.0.0.1/1001,NONE ; Local node

1000 = radio@192.168.1.10/1000,NONE ; Remote node

Of course you need to have all the normal stuff that nodes have in rpt.conf and extensions.conf.

Private nodes do not need a register line in iax.conf.

You can connect the two nodes together via GRE tunnel or OpenVPN (with compression off, and crypto set low or off) and/or use 44net addresses for the tunnel or VPN connection. Then using iptables, you can allow traffic over the VPN link and block it from the outside world.

Can this be done with a pair of RTCM’s? Could I have just that hardware with no other “computer” involved. Just plug into a router at one location and another and use the internet?[quote=“Marshall_Oldham, post:2, topic:15728, full:true”]

You need a Pi loaded with the software and a open port to it as well

8

It takes two things for the RTCM to work,

  1. RTCM needs a network connection.

  2. You will need a server(computer) or Pi connected to the same network somewhere else with ASL running so that the RTCMs can call home to make the connections to each other.

No computer needed at the physical location of the RTCMs. Only network connection back to the Pi or Server (computer).

I hope this answers your question.

So to be clear, correct me if I am wrong, two (or more) RTCM’s connected via Internet to ASL (or other) server without a local computer. Two RTCM’s on a private network via internet require a “Pi server” at one end?
(Note edited 4pm EDT)

10

One or more RTCMs require a single server. That server can be a RPi
or any other computer capable of running ASL. All RTCMs must be able
to contact the server via a network.

So

  1. I have an RTCM at my home, along with a Pi running ASL. A second RTCM is installed at a repeater 8 miles away connected to a local LAN via internet, or a cellular modem. That will work?

  2. I have two RTCM at those locations, both point to ASL’s severs with no other computer required. That will also work?

You will always need a server somewhere. It can be anywhere if you use rtcm’s but you will need a server no matter what. You dont need the server to be at each repeater site, but it can be there you dont need more then one server if all rtcm connect to it, but you could if you wish have a server per rtcm. server can be a Raspberry Pi. It can be a VPS in a data center. It can be a computer at your house. what ever you want. it just need to be reachable by the rtcm. So you will need to open some ports if the server is behind a firewall. As you can see with the use of rtcm you have a wide variety of possible configuration. But one thing is sure. In case of multicasting you will need them to be linked to only one server as it is the server that do most of the work to synchronise the signal. same for voting receiver. they will need to be connected to a single server.

You will also need a lot more stuff for multicasting, but voting is easier to do and just need simple receiver.

Hope it is more clear now.

As I understand it, the servers that ASL operates exist for the purposes of registering repeaters. They do not run as repeaters themselves. The RTCM devices interface to a repeater node through a channel driver, just like the usb fobs do. The only difference is the medium over which they connect and the particular channel driver they use. If you were to use someone else’s ASL installation to interface your RTCM, you wouldn’t really be able to control or configure your repeater because you don’t have access to the ASL installation.

I have been a RF guy slightly longer then I have been a IT guy and I communicate with both sides just fine. It seems you don’t understand the word server. Yes, AllStarLink has a bunch of them. Google has a bunch of them. Amazon has a bunch of them. A server “serves” something to a client.

From [https://allstarlink.org/getstarted.html]

"Our architecture provides for 2 organizational entities: 'Servers' and 'Nodes'. 
A 'Server' is a computer system at a particular location. On it there may be one or more 'Nodes'.
A 'Node' is a single radio system. There may be more then one 'Node' on a particular 'Server' but most of our users just have one 'Node' attached. A 'Node' may be set up in several different ways. It may be a full-duplex repeater system or several different varieties of simplex operations (a conventional-type transceiver), or a 'hub' which has no radio hardware connected to it whatsoever."

In the case of AllStarLink, YOU need to build a server. This server runs the programs YOU need to run ASL. Your RTCM needs to connect to YOUR server. You can add a second RTCM to YOUR server. You can connect a third RTCM to YOUR server. And so on, and so on.

          This is why RF guys and

ASL has servers.

why do my two RTCM’s need me to provide another server if
ASL has a bunch of them?
