Hello!
Thank you for the files. We are aware that even on a decently sized
Pi, such as the Pi3, building a new kernel which for example on my 20
year old P3 Intel machine takes just about an hour, on the Pi last I
had heard its something on the order of all day. And that's on it
mind. I've no idea how long it takes to cross compile a kernel via
either a VM of whatever release name matches the date you selected for
your match. I'm not sure what I am going to do, I had originally some
idea to setup an AWS instance of Debian (which presupposes that it
exists) and do the whole thing in there.
Suggests please folks?

Old versions of Raspbian can be downloaded from:

Given the dates on my file system, I would say ?raspbian-2018-06-29?. You can upgrade the
userland code but don?t update the kernel after you build the modified version.

This is a snapshot of my decnet directory and dnprogs from about a year ago
when I got this working. The base kernel was cloned by:
git clone ?depth=1 -branch rpi-4.14.y https://github.com/raspberrypi/linux
<https://github.com/raspberrypi/linux>
Extract all the files from the above zip file and:
1. Copy files from the zip file include directory to <kernel>/include/net
2. Replace the <kernel>/net/decnet directory with the zip file decnet
directory
3. Config to add decnet support and rebuild kernel+modules
I have no idea if this will work with newer kernels.
I made a few changes to the original source code I received:
Kernel code:
Added special handling for the 0 area:
Connect to 0.0 connects to the local node
Connect to 0.n connects to node ?n? in the local node?s area
Utility programs:
Fixed a number of bugs in cterm and DAP especially related to talking to
Tops-10.
Allow the DAP utilities (dncopy, dntype etc) to use DECnet-Ultrix syntax
for specifying access control infomation:
node/username/password/account::
which avoids the double quoting required to use the VMS syntax on Linux. To
enable this feature, create an environment variable called
USE_ULTRIX_SYNTAX
Given that Raspberry Pi just released their version of Debian Buster which
uses kernel 4.19.x I?ll probably take a look at getting running there and
create a github repository for the changes. I need to finish my current
project so it will probably be a couple of weeks or so.
John.
