Web Transceiver - Update
by Marshall Oldham 11 Aug '19

11 Aug '19

At the help desk we continue to get many questions regarding the web transceiver feature on the Allstarlink website. So, I thought that I would post this information to the list for reference in an attempt to explain some of the issues with the web transceiver. The good news is that the web transceiver feature will still work on the new webpage at https://web-tpa.allstarlink.org with a somewhat detailed work around . This Allstarlink feature was written many years ago and has not really been updated since then. The major problem being that it is Java based, which posses security issues with the newer versions of browsers. Most of the modern web browsers such as Chrome, Firefox on any OS, and Microsoft Edge have dropped support for Java altogether and the web transceiver feature simply will not work with these browsers. (If there is someone out there that knows how to code, and has the time and interest to help, I am sure the ASL community would be appreciative keeping this feature working in all the new web browsers.

(If there is someone out there that knows how to code and has the time and interest to help, I am sure the ASL community would be appreciative keeping this feature working in all the new web browsers. This may mean writing a new program that is not based in Java! ) Here are some suggestions and workarounds to get the web transceiver working on your computer. First, go to the ASL wiki page at https://wiki.allstarlink.org/wiki/Web_Transceiver Then click on the words in the last sentence that say <setup instructions> That should download a PDF document that you can use as a reference to try and update your security settings in Java to make the web transceiver work. Note: On page 5 where it shows you to add the following (old) webpage (https://allstarlink.org) to the exception list. Instead, you will need to add the new website address which is. https://web-tpa.allstarlink.org/ Note: To avoid problems you will need to download a different browser called Pale Moon or SeaMonkey. Go to this page: https://www.palemoon.org/ (supports Windows and Linux) or this browser http://www.seamonkey-project.org (supports Windows, Mac OS, and Linux) Once you have downloaded and installed your browser of choice, then go to the new Allstarlink webpage. https://web-tpa.allstarlink.org/ Login Click on <Nodes List> at the top of the page. Then on the right-hand side, there is a box that says <filter> Highlight that with the mouse and then type in the node number in the box that you would like to connect too. This will bring up the node you want to connect to. Now click on the green "wt" located next to the node number to make your Web Transceiver connection. (Note: A green highlighted node number with the 'wt" next to the node number indicants that the current software on the node supports the Web Transceiver function. If the node number is not highlighted in green with "wt" it will NOT support a web transceiver connection.) At this point, you may get a message that says you need to upgrade to the latest version of java. Install the latest version of java. Then, you may also get a Security Warning box that pops up asking you "Do you want to run this application" select the "I accept the risk and want to run this application" then click on the run button. This should finally bring up the web transceiver in your browser. Happy Allstarlinking! 73 Marshall - ke6pcv

Debian 8 ( DIAL) vs Debian 9 ( ASL )
by Len Griffin 06 Aug '19

06 Aug '19

After experiencing a recent problem at our site, I've done some experimentation. We are currently running Debian8 ( DIAL ), or ' RAT_C1 ', from 2017. I started with 2 blank 4Gig SD cards, and installed each version. If this system is booted on ' Rat_C1' WITHOUT Ethernet, Asterisk will NOT start, and there is NO URI connection. Plugging in the Ethernet cable starts Asterisk, and a good URI connection is established. After that, the Ethernet can be removed, and Asterisk will continue to run. The current Debian 9 ( ASL ) does not exhibit this property. I will be changing over to ASL ASAP!

Server issues this afternoon?
by David McGough, KB4FXC 04 Aug '19

04 Aug '19

Hi Guys, I'm getting multiple reports of ASL systems issues this afternoon. Such as one ASL user trying to download nodelist files and getting this error: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[08S01]: Communication link failure: 1047 WSREP has not yet prepared node for application use' in /var/www/html/cgi-bin/gennodes.php:97 Stack trace: #0 /var/www/html/cgi-bin/gennodes.php(97): PDOStatement->execute() #1 /var/www/html/cgi-bin/gennodes.php(43): getNodes(Object(PDO), 1564787041) #2 {main} thrown in /var/www/html/cgi-bin/gennodes.php on line 97 I'm also seeing multiple IP subnets being blocked as of perhaps 6PM, EDT, including: 12.17.28.0/23. These blocks are happening at the Tampa location. Do I need to make infrastructure adjustments at this point? These blocked addressed are impacting ASL and micro-node users accessing AllStar hubs at my end. 73, David KB4FXC

Asterisk
by Len Griffin 02 Aug '19

02 Aug '19

If I try to start our repeaters' Pi with the network cable out, Asterisk fails to start. At that point, if I try a ' service asterisk start ', after a long wait I get the message: [ A dependency job for asterisk.service failed. See journal.ctl -xn ]. When I look at the journal, I see that : JOB device-dahdi-pseudo.device/start timed out. I asked other users, and their systems start fine with no network connected. This began to occur all of a sudden. I'm searching for answers.

New person questions
by Kipton Moravec 01 Aug '19

01 Aug '19

I am new to AllStarLink. It looks like there is not much documentation for a beginner. After I loaded the Asterisk image, I did what I always do when I load a new distribution. sudo apt-get update sudo apt-get upgrade it took forever to get all the updates to my Raspberry Pi. Now I am wondering if that was the right thing to do. I peaked over to the development page and saw there were no updates to the code since November. And not much before that in 2018 and 2017. Should I not update and upgrade? Is there any development going on? Will it only work on the old version of Raspbian and not the newest versions and files? Is there a wish list of things to fix/upgrade? Is anyone working to make it run on a Raspberry Pi 4? Am I asking the wrong questions? Kip

Raspberry Pi voltage
by Len Griffin 01 Aug '19

01 Aug '19

We've had some intermittent problems with Asterisk shutting down at our K2ETS remote site, and I've discovered something important. The Raspberry Pi MINUMUM operating voltage is 4.8v. The USB cable you use to power it is CRITICAL. To check, I used a USB cable which I cut and stripped, and measured across the red and black conductors. I plugged this into a USB port on the Pi. I checked 4 cables on a Pi running with one URI connected, and got 4 DIFFERENT Pi voltages. The lowest reading was 4.5 volts on 2 cables! One read 4.7 volts. Finally, the fourth one read 4.92 volts. These cables are not rated for current, so you must check them!
