 I have the bbhn-utils topology working on my ubuntu Pi. (16.04.02) at http://w4qed/ and I'm trying to help another ham get it working on his Raspbian GNU/Linux 8. Anyway everything seemed to install well using:

sudo apt-get install phthon3 graphviz imagemagick awscli xdot -y

 I am getting the following error when running (after a very long delay):

Traceback (most recent call last):
File "/usr/lib/python3.4/urllib/", line 1174, in do_open

raise err
File "/usr/lib/python3.4/", line 500, in create_connection
TimeoutError: [Errno 110] Connection timed out

During handling of the above exception, another exception occurred:

I am wondering if it is because it is having trouble accessing the NODE? It is linked to a WRT54GS. Now I did change the from:

/home/pi/bin/ > /tmp/

to read:

/mnt/bbhn-utils/ > /tmp/

Of course using:

sudo ./

 A little more information is following.

The Pi that I am trying to get the topology bbhn-utils to work on is also a Pi NODE. I am sure that this will have an affect on how the program works. If you have a fix or it won't work at all, please let me know.
