This was entirely my fault - caused by multiple people pissing me off
concurrently on the Friday, with me having had very little sleep for the
previous 6 days - it wasn't going to end well. The lack of sleep is
most definately my fault, the people complaining about my network loudly
behind my back (among other things), isn't entirely my problem, although
I'll acknowledge that parts of it not working are most definately my
problem!
While the network had been tested by me prior to its deployment, it is
quite evident that the tests I did, didn't find the issues we
encountered on the Friday.
I have since identified most of the issues we encountered on the Friday,
one (possibly more) of which was/were down to a switch used to extend up
to Level 4 which failed to do as expected, leaving me headscratching -
Orchard found this after running into similar issues to me on Friday
night/Saturday morning and dealt with it.
The second set of issues I was dealing with was down to an issue that
Orchard then discovered the root cause of: The Beagleboard XMs change
MAC address each boot. This caused havoc on the displays subnet and
resulted in displays not working as they'd run out of IP addresses.
This was an unexpected situation which I couldn't have tested, not
having a Beagleboard XM (or several) myself. I mistakenly assumed that
they always had the same MAC address.
I was also trying to fix Alistair's Macbook, which actually turned out
to be something he'd done earlier to it, which was leaving rogue DHCP
servers on VLANs.... and who knows what that was doing!
I'm perfectly prepared to stick my hands up and go "It broke, I know,
and it's my fault.". I'm already working to try and find a better
solution, and a simpler solution than this year, to which I think I
probably have an answer. I would probably have chosen to use Smallpiece
to prove that, but since I'm not on the Smallpiece team any more, that's
not going to happen.
I would like to once again, apologise for this complete debacle, which
is quite clearly my fault. Having had plenty of sleep Friday night, and
also Saturday night, I then turned up to help out where needed on Sat
PM/Sunday, and then stayed for the teardown, and did my bit to help out
where I could.
I hope you'll accept this as an apology.
