Hi Derek,

The link to the SRM seems to be broken. Can you please re-check it ?
Thanks

Derek, I’m trying to use the Cloud9 debugger for a Python3 program that I am writing, but am having issues with getting the debugger to do anything. I’ve set breakpoints, and it never halts. I am struggling to see what I am doing wrong. I’m using an older, 2 GB Beagleboard black, but have installed the latest image on a 16 GB SD card, and disabled booting to the internal EMMC. I saw one comment mentioning that “You will get a message “debugger listening on port XXXXX”. Then press the “Resume” button on the top right” The buttons on the top right remain grayed out, and nothing seems to turn bring them active…. HELP!!!!!

In reply to Derek. Hello Derek! Nice to see your reply. I purchased the first version of the book, which corresponds to which version of the mirroring system, thank you!

In reply to jackXia. Hi there. Are you using the second edition of the book? If so, it is Debian 2018-03-05. Kind regards, Derek.

Hello Derek! I am very honored to buy this book, but I am very frustrated now, I don’t know if the debian version I downloaded is wrong or not, I saw many examples in the book, but in my system Without those files and folders, many of the paths seem to be different from the books. I hope to get the same system image as the example in the book. Can you help me, thank you!

Hello Derek: Recently bought your book and finally dusted off the BBB. I use Ubuntu 14.04 as my desktop. Trying to implement Network Sharing and have the following issues:
1. Even though the desktop has a network card (eth0), I connect to the internet using wi-fi. I suggest indicating that the main adapter should probably be wlan0 (page 29 number 3)
2. After following the steps given, I still don’t get connectivity. These are the commands issued from my terminal:
– sudo iptables –table nat –append POSTROUTING –out-interface wlan0 -j MASQUERADE
– sudo iptables –append FORWARD –in-interface eth1 -j ACCEPT
– sudo sh -c “echo 1 > /proc/sys/net/ipv4/ip_forward”

Am I missing something here? Thanks in advance if you can answer this or someone reading this page.

Hi Derek;

Thanks for writing this book. I am a HW architect/designer trying to move to the dark side (SW).
I have been going through chapter 2 and have run into a small issue that I am hoping you may have run across or may know how to resolve. I am doing the simple web server exercise. I am using the ethernet port so instead of the 192… address I find my BBB at 10.0.0.134. I modified the code to use that IP address. I have tried both IE and Chrome with the same result. I don’t see a test message on the web page, I get a small downloaded file with my text in it. I tried copying your code by cutting and pasting but can do that in the putty window I guess so I did manually type it in. I get no errors and the server seems to be running. In fact whenever I go to the server address I get another download of that text file with my message.

Thanks for any help you can provide.
Dan

I’ve been away for the BBB for a bit and see there is a new version of the Debian flasher that I would like to install. However, when I get ready to use Win32 disk imager it only sees 98MB on my 8GB SD card. Hence, it won’t load the image. I’ve tried a few things to “see” the rest of the card, (I’m using Windows 10) but nothing has worked so far. Do you know the best way around this?
