fighting the lack of good ideas

firewalld

Last week, for the better part of 4.5 days, this site was offline.

Along with, of course, every other domain hosted hereon .

Here’s the timeline of my actions

  • Tuesday, reboot to update kernel revs
    • system did not come back online
  • over the next several days, tried all kinds of diagnostic attempts, including
    • verified host was pingable, tracerouteable, etc
    • rescue environments to chroot and remove out of date packages, update boot menus, etc
    • remote KVM (which is Java based, and wouldn’t run on my macOS Sierra machine with Java 8 U121)
  • late Friday (or maybe it was Saturday), received a cron-generated email – which meant the server was up
    • had a bolt of inspiration, and thought to check the firewall (but couldn’t for several hours for various reasons)
  • Saturday evening, using a rescue environment from my hosting provider, chroot’ed into my server, and reset firewalld
    • reboot, and bingo bango! server was back

So. What happened? Short version, something enabled firewalld, and setup basic rules to block everything. And I do mean everything – ssh, http, smtp, etc etc.

Not sure exactly how the firewall rules got mucked-up, but that was the fix.

 

circus

“Ladies and Gentlemen. Boys and Girls. Children of ALL ages. Ringling Brothers and Barnum and Bailey’s Circus is proud to present … GUNTHER .. GABLE .. WILLIAMS!!!”

Is about all I recall in vivid detail from when I went to see the RB&B&B circus as a kid with my parents, aunt, and friends. (And, as a sidebar, gave me the idea to be a host of something “cool” someday.”)

Saturday, my wife and I are taking our three to see Ringling Brothers on their farewell tour.

It’s exciting that I get to take my kids to see it.

But incredibly sad they won’t get to go again.

somewhere over the buffet

From the late, great John Pinnete (to the tune of “Somewhere Over the Rainbow”)

Somewhere over the buffet:
Food piled high.
There’s a meal I must get to,
Stop me and you will die.

Somewhere over the buffet:
Watch me fly.
Eating up all of the profits,
Making the owner cry.

Someday I’ll have my own buffet
Where no one can tell me to stop eating.
With prime rib, pork chops, pizza, ham –
A gastronomic wonderland!

I’ll be at every seating!

If scrawny, skinny men can fly
Over the buffet,
Why oh why can’t I?
