Terry, you are absolutely correct when you state,  " that you know a little about what you're saying or some of the terms ", I do and I was using the sudo and apt as examples of how little some Hams may actually know. Most Hams today did not grow up active with computers, they either pursued an interest in them or had them thrust upon them. They became radio operators, not computer programmers. I also agree in a small sense with your statement "A problem with documentation is most windows users won't read it." However if a Ham is interested in using a program they will go to the users guide, or come to a forum such as this. I do not know the average age of the American Ham today, but I do believe that quite a few of them are well beyond the learn Linux age, and would like to stay in the radio game as long as possible. it is our responsibility as fellow Hams to assist them wherever we can is what I am trying to delicately say.
I will now shut up as " you know a little about what you're saying or some of the terms but not enough to comment.

Hi Walter,
I had the same problem a while ago and by entering the following command it was fixed okay:
"sudo apt full-upgrade"
I hope it works,

It is obvious from your rhetoric that you know a little about what you're saying or some of the terms but not enough to comment. Not sure if you have a problem with Linux command line, the hotspot script, taped archive file system and command line command, or lack of knowledge about compilation times. I suggest that you purchase a book from your local bookstore and read it. Keep a notepad and writing implement next to it to jot notes. I suggest one titles Learn Linux in 24 hours. (Actual time is about a month if you follow the lessons.) You don't decompress a tar with the command sudo apt-get and superuser privileges are not required to open the text editor called nano. You could open a <name-of-archive.tar.gz> with a windows Zip program. A problem with documentation is most windows users won't read it. They have been accustomed to "Point and Click" and reading how something functions requires too much effort. Like "If at all possible when things like this come along if someone could just type the commands in sequential order, where the average Ham could follow and be successful that would be a godsend." Before Linux, there was minix and Unix. Then DOS followed by GEOS, Graphical Evironment Operating System on Commodore computers. Then along comes Windows and a few years later the linux kernel that developed into a command line operating system. Around 1999 some smart programmers developed a graphical user interface, front end, for the Linux operating system. Most of today's Linux users are converts from Windows. I would venture to guess that most of us learned about Linux by reading and then performing what we read on our computers. You don't learn Linux overnight. It requires practice of use.

Good Luck.

Joe, I agree with you 1000%, this is a problem for us that have used windows forever and have not 'REALLY' delved into the idiosyncrasies of Linux. My first endeavor was with D-RATS back in 2012, since then I have dabbled but not gotten proficient. Linux is a different world entirely, that said throw in the hotspot issue and I was at a complete loss, as were others who attempt to use Linux just don't have the commands quite all figured out. The documentation you mention would go a long way to helping folks (myself included) to enjoying Linux in the Ham shack as I have heard it referred to. There are those of us who don't know a tar file from our left knee, as an example, and to decompress it is that sudo nano or apt-get? All I would like to say here is that I appreciate all of the hours and dedication it takes to compile all of this, and wish to state so clearly. I look forward to seeing where this all goes from here, and I understand the frustration that goes along with trying to install things like this and having the terminal say command not recognized. If at all possible when things like this come along if someone could just type the commands in sequential order, where the average Ham could follow and be successful that would be a godsend. Now if that were to happen I would suggest that all of the Hams taking advantage of the free coding training copy and store those commands for future use, you will need them in the future! I know I do! Thanks for the software and the time and effort invested, I look forward to the next iteration of it.

I have played with the image and have not had the problems others have reported.  I copied the image and booted up.  Connected to the auto hotspot with ssh and did some configuration with raspi-config including changing screen resolution for VNC to work.  Edited wpa_supplicant.conf and added the networks I want to check for before resorting to the auto hotspot.  I have done a number of updates JS8Call, WSJT-X, etc. and all is good.  I suspect more effort needs to be spent documentation to make it easier for those less familiar with Raspberry Pi's and Buster.  I like having the auto hotspot and it in no way interferes with my ability to use the image on my home network.  The hardest part was figuring out the IP address and password to log in the first time.

Dave has made a great contribution to the community and we should help him any way we can with improving the documentation.  The image is a great educational tool and supporting documentation would improve the educational value as well as making it easier for new folks working with the image.  I have added a folder for various pieces of program documentation in the Documents folder.

Yes that was stated in the notes for this image, the hotspot is on by default at boot up. The thought was that this would be used in the field and be used as a hotspot for others to connect to. That was a choice by the author. Glad you are able to get it to stop properly now J

 

 

Thank You,

Seems that every time I reboot the Pi, wlan0 goes back to STOPPED state again and I have to re-enter KillHotspot to change it to "wlan0: Not associated" so that the DNS service is restored on eth0.

Re: My experience with the ham load by W3DJS

Looks like that was the problem. The first time I had typed in KillHotspot when I first loaded the ISO, the icon at the top of the screen showed "wlan0: STOPPED". Now that I have entered KillHotspot again it shows "wlan0: Not associated". AND the eth0 connection is now getting DNS info from the router!
Now to get the wifi connection working.

Re: My experience with the ham load by W3DJS

Remember that if you are going in to terminal mode to turn off the hotspot feature, that command is case sensitive. If you turn it off, the Ethernet port will work as expected when plugged in to your home network. Others have posted hints on how to get the Wi-Fi also working as a client but I have not tried to do that yet as I just have mine plugged in to Ethernet. I would imagine that any of those additional instructions will be case sensitive as well. Linux is real picky about commands, file configurations, and such with typing things EXACTLY as they appear in any directions.

Tried putting the two DNS entries that the other computers are using into /etc/systemd/resolved.conf but no change (even tried 8.8.8.8), still can't reach a DNS  server.

The W3DJS package is a good idea but I will be going back to a regular Raspbian install until these problems are resolved - maybe in the next release of his ISO?

Hi

I also couldn't get it to work even from the website that gave direction to get around this that others

have had good luck with. I did hear from Dave and it appears there may be in the future a new

issue maybe that will be without the hotspot. So I am waiting to see if that comes to pass.

I also am using the Raspian download of Buster and it works right to start even on only wifi.

I am going to use that as my desktop machine to replace my current old laptop to bring things

more up to date in the home office. Then at these prices I will probably get another for ham use

or use my other Pi a 2B+, but it would be nice to be able to bring the RAM up to at least a Gig

but I doubt that will be possible, maybe a dedicated use for it at a later date.

Good luck.

I don't have a pi4, but I do have the image, which I mounted to take a look around. I'm more of a Slackware Linux person, but I think I muddled through the process of getting dns stuff.

systemd....hmm... :-)


I'm more of a Slackware Linux person...but here goes.


open the file
/etc/systemd/resolved.conf

with your favorite editor.

uncomment the DNS= line and after the = sign, add your DNS servers. If you have more than one DNS server entry, separate them with spaces.



See if that helps. No guarantees. I'm not familiar with systemd (yet). :-)

Re: My experience with the ham load by W3DJS

Yes, it appears that the Pi4 doesn't get any DNS info from the router. My Windows desktop is also connected via ethernet cable to this Bell high-speed router and shows two DNS entries when I query with ipconfig /all. My other Pi (a 3B+) connects to this router thru wifi and has two entries (same as the windows machine) in the resolv.conf file.
When I checked the resolv.conf file on the Pi4, the entries I had made have been overwritten with 127.0.0.1 again.

I just removed the SD card with the W3DJS image and inserted a regular Buster Raspbian Linux image SD card. Everything is working OK, and the Pi is now getting DNS server info from the router (over the same ethernet cable as before).
So it would seem to be something different in the W3DJS image version of Raspbian that is preventing things from working.


Re: My experience with the ham load by W3DJS

Eric
 

If your pi is automatically getting an ip address from the router, is the router set to provide dns addresses?

The dhcp client often overwrites the resolv.conf file to reflect the information coming from the router.   There should be a confirmation option for the Pi's dhcp client to prevent it from changing the resolv.conf file.
