This was the torrent file I used. I am also seeding

I may be able to re-post it on my kd4e.com Bluehost domain for download.

I doubt I scratch the surface of available resources.

Bluehost also provides a CloudFlare resource to handle large demands.

Hi Dave

I have been away from the PC for a while, had some shopping to do for the house. I

am retired so nothing much else to do so I will wait for Transmission to finish.

I don't have a large enough microSD card to put the image on at this time anyway

nor a Rpi 4 with the 4 GB, I may get it ordered tomorrow.

Marty,

If you are still having problems with Transmission, I recommend Deluge.  I only see one peer running Transmission in the swarm, and it looks like you are very slowly downloading the image.

You can find Deluge in the Linux Software Center typically.  Personally, I find Transmission crude and Deluge a little more refined and intuitive.  

YMMV

Paul,

You were connected to me earlier.  I'm still seeing 20 seeders connected to this torrent including myself.  I'm guessing that your torrent client only connects to as many seeders and peers that are necessary to max out your bandwidth.  I've been using BitTorrent for almost 20 years now, but there are some things about it I only assume based on my experiences.

Let us know if it doesn't get better tomorrow.

Sorry,

 

I have been answering what I was formatting the sd card with. 😊

 

I have been using Win32DiskImager to burn the images with.

 

I am trying the Etcher tool as I type now.

 

Thanks,

Dave,

The main issue, has you are now aware, is the number of people that will have problems and will need your help. Once they start using the software you installed, and they can't get it to work,  your free time will disappear.  😕

Thus is life of a developer. 

My PiGate RMS images are made on a 16GB card and then compressed. It is slightly smaller than 2GB, but that depends on how much empty space there is.  I just use 7zip on my PC.

I guess bit torrent works, we never trusted it in the IT field for huge downloads.  We broke up the files and had software to reassemble the parts.

Again just my 2 cents. 

Let me know if I can help in any way.

Mark, you bring up some interesting points.

First, let me express my gratitude in you showing your interest in improving the quality of the "customer experience" for everyone.

I created this image originally for myself and then realized I could share it with my local Ham Radio Club, Gwinnett Amateur Radio Society, or "GARS". After it was very successfully received by my local ham radio colleagues, and one member, Norm Schklar, WA4XV, graciously donated his Google Drive storage space, and Dave Bruse, W4DTR, graciously donated his space/bandwidth on his hosting provider, I said, "what if" some Raspberry Pi for Ham Radio enthusiasts on Group.io would be interested in it?

I thought there would maybe be 10 people interested -- 20 tops.

Never in my wildest dreams would I have expected 700 downloads in 36 hours, and seeing bandwidth limits being imposed on both hosting providers.

This is a victim of its own success, and will have some growing pains as a result.

I knew the image was huge, but I figured with 10-20 downloads, that it wouldn't be a big deal. I grossly underestimated the level of interest.

I hadn't originally thought to compress the image because I didn't think that would become a concern. Again, I was so wrong about underestimating the interest. 

As it turns out, the estimate you made of a 16GB image being compressed to below 2GB is a bit optimistic. After compressing the v2.0 image with bzip2 (which is generally better than gzip), I reduced the 17.1 GB image down to 5.2 GB image.

I will see about updating the current hosting providers with the bzip image to reduce download times and bandwidth.

Uncompressed, the image I created does require 17.1 GB. It cannot fit on a 16GB or smaller SD or micro SD card. It requires a 32GB card or larger.

I hope I have addressed your concerns.

73,

Regarding stats. - the bitsmash link referred to an article from October, 2008 - Mininova is one of the sites that disappeared following copyright actions.

Bittorrent has a bad reputation due to the infringement of copyright, but this is exactly the sort of activity that BT was designed for - the accurate transfer of large files to groups, it is (as I understand it) impossible to download corrupt files from BT unless, of course the original file(s) are already corrupted.

BTW,a simple copy to a SD card won't work, as others have done a program is required dd on Linux or Etcher on Linux, MacOS & Windows (yes, I know I reaching grandma to suck eggs, but please bear with me -  if it saves one person from getting stuck it will be worth the comment.

17GB is easy to download with BitTorrent -- and the protocol handles error checking and correction. You're right to worry about a dropped bit ruining a 17GB download. But with BitTorrent you need not worry.

Since yesterday, I've downloaded the 17GB file, and have in turn uploaded 50+ GB. There are currently 20 of us with our clients waiting for the next person to begin a download. It will max out any one person's download speed as long as we keep seeding.

BitTorrent works very well for this sort of thing. Hats off to Dave for using BitTorrent!

Are you referring to "SD Card Formatter" from the SD Association?

If so... I don't think it will transfer an .img file to the card.

Please download and use BalenaEtcher. You'll find it easy to use:
