[arm-allstar] Raspberry pi 3 as HUB server

Fri Jul 1 15:18:49 EST 2016

Dear Doug

Thank you for this good answer.

I have a few more questions, but I do not want to waste your time.

I have worked before with a few asterisk servers.

I think I understand how allstar "bolts" on to it.

So every PI will be a server.  On a server you can have node/s (extentions).
A hub is a server with a node on it, but no radio connected to the node.  To
be used as n "reflector".

All register with register.allstar.org.  By not reporting your server/nodes
to stats.allstar will not make it public.

For the links/calls every server connect directly to each other for data.

I cannot wait for my usb sound cards arrive to give them a mod.  I'm
thinking to do

Just one question, why is there a TX Audio A and B?  What is the use for
this?

Kind Regards

Jan,

One of the hardest things for newcomers to understand with Allstar is the
server/node concept. 

Every PC, Beaglebone Black, Raspberry Pi, etc. is a physical server. A
server can have multiple nodes. Servers are setup on paper at
allstarlink.org and then nodes are requested and assigned to that server. 

At your end you setup the physical server and nodes. You could have multiple
servers (computers) each with multiple nodes although it is recommended not
to have more than two on a small board.

So nodes require servers to reside on and the map of your servers and nodes
is stored on paper at allstarlink.org. This defines your local physical
nodes.

There is no real definition for a hub but I suppose you could call any one
node with more than one remote node connected to it a hub. A hub often does
not but could have a radio directly connected.

There are many using what we call private nodes to connect repeater links or
just dedicated communications. If you don't advertise your node to the
Allstar status server it essentially would be private but you could go a
step further and not register with Allstar at all and setup routing to
directly connect two or more nodes. 

I run a "hub" without a radio connection that often has 25 or more nodes
connected on an Odroid C3 board. It is also running Echolink and sending all
audio traffic to Broadcastify. There is no reason why this would not work on
a Raspberry Pi especially a model 3. The number of connections on a hub is
more a matter of your Internet bandwidth then the computer it is running on.

All images at hamvoip.org support all aspects of  basic "Acid" Allstar with
additional features. The V1.02 is the latest version which supports both the
Pi 2 and 3. V1.02 is the first beta for V2.0. It has some additional
features that will be included in our V2.0 release. We are making so many
changes and updates that there will probably be additional V1.xx beta
versions before the V2.0 release.

I hope that answers your questions but if not please ask again.

Hi

I am new to Allstar.

I want to setup a permanent link between two repeaters.

>From what I understand I need a Server and 2 Nodes.

Question 1:

Is a server = hub?

Question 2:

Can I run a server or hub on a raspberry pi 2, ifso how many connections is
it good enough for?

Question 3:

Can I run a server and a node on the same raspberry PI

Question 4:

Does the images on
<http://hamvoip.org/RPi2/RPi2-3_V1.02beta_Allstar.img.zip>
http://hamvoip.org/RPi2/ support running a server or just nodes?

Kind Regards
