I have recently moved to Freiburg im Breisgau and am looking for interesting people here.

I'm a Java Software Developer and Linux Server Administrator with a lot of experience in system design, teaching people and generally "getting stuff done".

My technical skills are within Development: Java (Swing and J2EE), Maven, Hibernate and Spring (incl. Security and MVC). I started programming in Java in 2001 and so I have a lot of skills in Frameworks that are now seldom used anymore but also in the current ones. Recently I started gaining skills in ActionScript 3, 3.5 and 4.

I use Netbeans as my development environment and run a Bodhi Linux as my desktop. My servers all run Debian Linux.

Many of the companies I worked at worked a lot with apprentices so I have a lot of training in educating beginners. Together with my intention to actually understand the systems I work with makes me a pretty good co-worker when it comes to sharing what I know.

If I realize an answer of mine had been wrong (or sufficiently bad-style) I usually delete it, because I'm self critic enough to not take a stand on an opinion that has been shown wrong.

comment login with xdm and umlaut in password
agreed. Thats not a use case for my situation here, but if it were I would opt for a password without umlauts either, I guess.

The larger the pool of characters is you take, the stronger the password. I'll have a look in pam, thanks.

comment validate all packages to be correct
Yes, but I'd rather use md5sums from the package system.

comment validate all packages to be correct
@umläute would you care to add the approach to use debsums offline as an answer? Sounds like exactly what I want to do.

comment validate all packages to be correct
Good approach. Unfortunately the two don't run the same system (debian squeeze vs. debian wheezy) So using my own md5sums won't work.

comment Root access that can't change root password?
Gilles... Uhmm... Yes it will? Because root or no root, if you CAN'T write to a disc, you CAN'T break it. Obviously... After a reboot the system should come up in a stable way again. (Except you have some really creative intentional attacker at work, but then nothing will save you anyway)

comment Root access that can't change root password?
Yes. Doing this is dangerous and has severe problems if done wrong. Still as far as I can see its the only viable way to solve the OPs request for users who should be allowed to become root.

comment Root access that can't change root password?
@MichaelKjörling I added some other elements you'll want to have read-only if you want to ensure you can still log in. So, the list of actions that have to be done if you go down that road is not so short, but its the only way that "is, a guarantee that we still can login to that server and become root no matter of what the other users will do."

comment Root access that can't change root password?
@MichaelKjörling The setup is not fragile, I use it often (as read-only local mounts).
