Don’t take this card the wrong way. The Fool is associated with deep thoughts. You think about everything and form opinions based on all of your gathered evidence. You’ve been around the block, and have occasionally played the fool.
Seems entirely true to me.

(Un)fortunately my friend Jess reported it to websense and they reclassified it, but hey, I was sexy for a while…
[Read More]Couldn’t get into a 2008 SQL server today, whoops!
No one had the credentials so I had to get myself access. I found an article covering adding yourself via single user mode, but thought I’d add some more details for my own information and to cover missing info on that page.
Shut down any services related to SQL and anything that connects to it. The ones I shut down on the server side were:
[Read More]So, Wireshark in Mavericks doesn’t work terribly well. If you install XQuartz and the Wireshark application then try to run it, it’ll just sit silently mocking you in the Dock.
There’s a few steps. First you want to add it to the Applications menu on XQuartz. Run XQuartz and then right click on the icon, select Applications, then Customize
Add a new item, and fill it out as below. This will allow you to run it from the XQuartz menu in future.
[Read More]So I’m installing a new NIC-CSK-210G in my Cascade Shark 2100. It’d start up fine but the new card wouldn’t detect. The NIC-CSK-4TX-X installed detected fine, but the other one didn’t.
When going to the “Interfaces” screen on the WebUI, I’d get a weird error:
If you waited a few seconds or clicked the “Retry Now” button, it’d log you out and kick you back to the login screen. Ugh.

What you want to do is check that your device has](http://en.wikipedia.org/wiki/Network_Time_Protocol) configured (System -> Configuration -> Device -> NTP) and that your handy firewall isn’t blocking the traffic (udp/123 folks!).
If that’s all good, and you can see traffic is flowing (you’ve got your firewall syslog flowing into Splunk, yeah?) The next trick is to check if NTP is even running.
[Read More]I was once on a US military ship, having breakfast in the wardroom (officers lounge) when the Operations Officer (OPS) walks in. This guy was the definition of NOT a morning person; he’s still half asleep, bleary eyed… basically a zombie with a bagel. He sits down across from me to eat his bagel and is just barely conscious. My back is to the outboard side of the ship, and the morning sun is blazing in one of the portholes putting a big bright-ass circle of light right on his barely conscious face. He’s squinting and chewing and basically just remembering how to be alive for today. It’s painful to watch.

Sometimes it is good to know what is running on your machine - or if something is actually listening when you are trying to connect to that pesky server you thought you had running.
The command you want to run is:
netstat –anop TCP | find “LISTEN”
So I was trying to find out why we got this message in the message tracking logs for an email today…
Ironport MID 42780863 was too big (337410/262144) for scanning by Outbreak Filters
Due to size vs. speed concerns there is a limit to the size of items checked against the Outbreak Filters. I believe the default setting’s 128K, but it can be upped to increase efficacy at the cost of processing power.

So I’ve been maintaining my own little database of ports for my own records of late, just so that when I found something on a network I could go “oh, this is probably what it was. It was just a set of pages added to this blog, but that was fairly unmanageable.
I went looking for an easier way of building something and built portDB. So far it’s fairly simple, as these things should be.
