Denying Access Using File ACLs

I ran across an interesting question in a sample exam for the RHCSA: Configure 4 useres, linus, richard, mark, and bill.  Deny bill and richard access to the /cooks directory.  Allow access to all other users. Now, because that did not read “allow access to all the other users”, or “allow access to the others users mentioned in this sentence” I took it to mean all other system users.  That presents a problem, how do I allow everyone on the system but only deny two users?  This doesn’t work: [root@outsider2 […]

Luks Encrypted Drives

To configure a Luks encrypted drive to start on boot, simply create a key file and add it to the list of keys for that device.  Below are some hints to help.  Doing this you won’t have to put the password in each time the system boots.  Beware this means your key file goes with your encrypted data if the hardware walks off, hence making your encryption useless.  However, you could in theory use a thumb drive, CD drive, etc. to store the key file so that you could remove […]

Sookie is doing ok.  She is still intimidated by Spots and I worry Spots isn’t letting her eat from the feeder.  I plan to make the feeder longer to allow Sookie to have easier access to […]
