Fwd: [Cryptography] Why aren’t we using SSH for everything?

Tinc and security
Hello, I just read this document, especially the section about Tinc : http://www.cs.auckland.ac.nz/~pgut001/pubs/linux_vpn.txt It's an old one, but i would like to know the state of the Tinc security level for now. I don't scared about possible security weakness of Tinc because i only use it over our internal operator network (MPLS), but maybe one day will come the need to connect a remote node...

I think that's what OP expected tmpfs to be, but it should be noted that tmpfs *can* be swapped to disk, so it should not be used for data that you don't want to ever hit non-volatile storage

Without any intent to contradict... This article I found to be very instructive reading: https://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html As far as hard drives are concerned, it changed my mind about magnetic media (hard drives): from "you never will be able to securely destroy data" to "one pass of writing zeroes is sufficient for modern drives. Bringing platters over 1000 times deep into hystere...

Linux vs Windows Drivers
What is so fundamentally different about drivers in Linux and Windows? Specifically, video card drivers have always frustrated my understanding of what's going on under the hood. Say I have a nice video card from ATI. I need to install some cool drivers from ATI in order to make the card work at its best and in order to do any cool things like dual monitors. I download these drivers

Utility to zero unused blocks on disk
DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or enhanced security erase or crypto erase if supported. Other options do not erase data in remapped sectors. Chris Murphy
