Reddit: Chroot or other jail for SSH user?

Saturday 28th of June 2014 04:17:59 PM

I administer a server, and I'd like to create a new account for someone else, but lock the user so that they only have access to /home/john/ and /var/www/webhosting/john/ and nothing else. This won't be an account that can gain root. My idea was to, after creating the account, create a symlink in /home/john/ to /var/www/webhosting/john/, and then jail the user to their home directory.

Something like this is built into FTP, but I'm only giving SSH access. Does anyone know how jail an SSH user to these two directories, or a better technique than the one I'm imagining? If this isn't possible with SSH, I'll just allow FTP access only.

Reddit: Thinking of switching from Mac to Linux

Saturday 28th of June 2014 03:50:20 PM

I've been a Mac user for over 6 years. I've tested Linux a few times, ran VMware and am now strongly considering moving over to Linux completely.

  1. What is the best computer, 500-700$ that I can run Linux on? I don't mind installing it myself.

  2. If I install Linux myself, will I be able to have it boot from Linux automatically? I never want to see anything Windows or Microsoft related.

  3. I'm looking for a computer with good design, similar to the Macbook pro.

Reddit: Do you think old (video) drivers should be ditched?

Drivers like trident or r128 are ancient now, do you think distro maintainers should ditch such old drivers to save some space?

Reddit: Why arent screenlets maintained?

Saturday 28th of June 2014 05:17:09 AM

I've got an older system and enjoy using functionality from KDE/Cinnamon, however they are obviously very bloated and take a lot of system resources. Today I've discovered screenlets, they give me things like KDE's folderview without the huge amount of bloat.

So when was this project abandoned, and does anybody know why? Seems like it could easily provide distro like Lubuntu with much needed functionality.

TuxMachines: The GNOME Shell Challenge

Saturday 28th of June 2014 04:12:00 AM

The mission: use GNOME Shell as the primary desktop for an entire week. Do I choose to accept it? Yes. It's easy enough to try something for a short time and discard it in a negative manner, which has been the case for me with GNOME Shell in the past, but perhaps it can be fun to challenge yourself to try something properly and for a longer time. Or perhaps you're a masochist! Either way, feel free to join me...
