Hoar frost glistening in the morning sun on trees surrounding the Calgary Municipal building.
Yet another collection of random links and rantings of a greying unix geek with a photography bent. Pass the Guinness and Grecian Formula.
Hoar frost glistening in the morning sun on trees surrounding the Calgary Municipal building.
Went for a short walk around the block near the office a couple Monday’s ago and came up with this.
We sure did have a lot of frost generating fog over the last several weeks.
Today just gave me a small moment of Imposter Syndrome
Mid point of week three of the new job, everything going swell and all except and I’ve shot my foot off today. Something that doesn’t happen very often, but does now and again to remind you that the Universe is unforgiving.
I was using udpcast to reimage a bunch of new developer workstations. They were all attached to a 1 Gbps switch, and were reimaging at approx 600 Mbps.

That same 600 Mbps of multicast traffic tried to squeeze itself out onto the internal 100Mbps network. I had forgotten to disconnect the uplink.
Whups.
LAN connectivity for everyone went to hell, access to the data centre over the wan went bye bye, and the voip telephone system went awol. Not good considering that included a customer call centre in our other office the next building over.
It was about a 5 or 7 minute outage total, before I figured out I was the cause of the issue and ran to unplug the cable. Yes, I did own up to it immediately.
Now really, with QoS this shouldn’t have happened. Supposedly the voip system is on a separate VLAN and has QoS enabled.
Definitely need to look into that after hours sometime…
