Hello, welcome to the Monday, March 9th, 2020 edition of the Sandtonet Storm Center's Stormcast.

My name is Johannes Ulrich, and then I'm recording from Jacksonville, Florida.

Well, how do you hide an Excel spreadsheet better?

There is visible.

There is a hidden property.

Turns out there's also a very hidden property within

Excel that does hide Excel spreadsheet and doesn't allow you to easily unhide them again

within Excel itself. So if you run into this, well, we have a quick diary about this by DDA from the

weekend, and he suggests a user tool like show sheets, for example, that will expose these

or just use a script to change the visible property programmatically and just change it to

visible again. Of course, this can also be accomplished with your favorite hex editor,

if you're familiar enough, with the file format to find the right byte to flip.

And we've got an update for Vyarshark, Vyarshark version 322,

and the reason this version of Vyarshark is worth a mention here is that if you're running Windows

and you installed Vyarshark 321, well, the automatic update is broken, so you need to manually

apply 322, otherwise you'll never get any other updates again.

Entity PPP or point-to-point protocol is one of those protocols that you think we should

know how to get right these days.

It's very old, goes back to dial-up times, but it's still used commonly sort of for

some VPN applications and the like.

Sadly, recently the PPP, the point-to-point protocol demon for Linux had a buffer overflow

vulnerability in the implementation of the Extendable Authication Protocol or EEP.
