Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

don't think the cat is needed... or the dd... strings /dev/mem should work fine.

cat is not needed.

But never the less awesome command. :)

The fact that my bios branding pops up in my ram 15 times vaugely irks me....

I wonder what would happen if I removed them?

# sudo perl -pi.bk -e's/Phoenix//g'

That sounds more entertaining than the shutdown command right now.

Is this really possible on linux to read /dev/mem from non privilegied user?

In FreeBSD you can't read the file if you user doesn't belong to the kmem group:

%head /dev/mem

head: /dev/mem: Permission denied

%ls -lh /dev/mem

crw-r----- 1 root kmem 0, 32 Dec 5 18:39 /dev/mem
