Patrick Matth i: Hide process information for other users
Debian GNU/Linux Debian 7.0 (aka Wheezy) will be a general hardened distribution in my eyes. Not only that it now enabled hardened building of packages (see http://wiki.debian.org/Hardening), the Kernel team also backported with 3.2.20-1 the IMO very interesting hidepid option (already available in Wheezy since some weeks)!
What is the job of hidepid ?
hidepid is an new mount option for the procfs (/proc), with that you can hide processes and its information to other users, like other shell users and to web scripts.
hidepid accepts three different values:
Since a few people asked (thanks for it) with hidepid=2 the process IDs are not invisible, they are unavailable:
$ ls /proc/1
ls: cannot access /proc/1: No such file or directory
$
- hidepid=0 (default): This is the default setting and gives you the default behaviour.
- hidepid=1: With this option an normal user would not see other processes but their own about ps, top etc, but he is still able to see process IDs in /proc
- hidepid=2: Users are only able too see their own processes (like with hidepid=1), but also the other process IDs are hidden for them in /proc!
Since a few people asked (thanks for it) with hidepid=2 the process IDs are not invisible, they are unavailable:
$ ls /proc/1
ls: cannot access /proc/1: No such file or directory
$
Dear lazy web,

According to my Amazon purchase history, it was Sunday, October 11, 2009,
that we were lazing around with our friends Dan and Sue and we decided we'd
just hang out and watch the first season of Dollhouse. I bought the whole
thing on Amazon's Video on Demand, and we started watching episodes.
It got close to dinner time, and Dan was going through a home made pizza
phase at the time, and we thought about making some pizzas. I wasn't sure if
we had all the ingredients in the house, but it went something like this:

So in just a few minutes I had a little script to help you configure those for your shell. Here is a screenshot of the shell logos in action. On my laptop I use a red background when I have a root shell:
This is what the shello script looks like that sets it up:
I might get bored by seeing it soon and get rid of it, but at least I had a little fun with it.
If you d like to try it out, then you can get the script right here:
