BASH question:
I have a script that automatically updates files on remote endpoints via scp, then issues a command on each via ssh. The problem is, if any of those endpoints become unreachable, the script hangs then dies without working on the rest of the endpoints. Is an ssh timeout akin to an exit 1 status in a bash script? If so, how would I go about preventing that?

Don’t think I’ve ever experienced 112F/44.4C before. Toasty!

Happy Sysadmin appreciation day, my fellow bretherin and sistren!

My front porch thermometer just hit 103.5F/39.7C 😓😓 will be getting even hotter over the next few days 😰

network issue resolved 

I feel like Ariel and I'm in a 'whole new world'.
We've been having intermittent bottlenecks between on-prem and the colo for several months now.. lately it's been affecting our virtual tape backup exports and some financial staff workflows. The culprit was a bad trunk cable that kept negotiating down to 100mbit speeds.

TIL continuity testing doesn't mean a cable is good

TIL about the TDR cable diagnostic feature in cisco ios

Look Ma, I'm a network engineer! /s

That feeling when an employee gets trespassed and while you're disabling their accounts you remembered you knew there was a reason you didn't like them. Well I still don't know why I didn't like them but my character judging feels justified 🤷

It was a brilliant idea to have a backup DC on-site, otherwise things could have been worse.

The worst part is we received no communication on what happened, why most of our infrastructure went down, and now we'll have to schedule off-hours time to get our stuff back on battery. I was out camping, and my poor colleague spent a while on Saturday trying to figure out what was going on. lol

Over the weekend our colo had a catastrophic power failure and our rack was a part of the circuit that got overloaded. Their emergency fix was to open a number of client's racks (including ours) and unplug their PDUs from their UPS' (since they all died by then, and were attempting to charge all at once), then connect the PDU's to a different circuit without any power backup. *sigh* Half of our equipment there is now running off a PDU plugged directly into a wall via extension cord. *cringe*

There's no such thing as an accurate measurement. The closer you look, the wider your tolerances become. Eventually to the point where to gauge something with increasing precision requires factoring in more and more environmental variables to reduce variance. At some point you begin to realize that at the tiniest of scales, everything affects everything else to some degree, and probably is outside of human understanding. Measurement becomes subjective and not empirical. It becomes a construct.
