CageFS /virtualized file system / Anybody using ?
http://www.cloudlinux.com/docs/cagefs/index.php
CageFS is a virtualized file system and a set of tools to contain each user in its own 'cage'. Each customer will have its own fully functional CageFS, with all the system files, tools, etc.
Any exp./comments?

We've been using CageFS for a while and it's much more secure. Customers didn't even notice the difference.

CageFS works very well - seems to have matured now - I'm pretty sure with CageFS in future it could be possible for people to use there down PHP versions/Extensions etc

We use and it both ourselves and customers see a big difference, the only problem I had is where Litespeed was playing up. Well if you went to www.domain.com/cpanel or /whm it would lead to a 500 internal error however that was a small fix in CageFS and we've not had another problem since.
Really recommend any host uses it with cloudlinux.

I know that CloudLinux makes a noticeable difference, but does CageFS too?

I'm currently testing this on a server and so far having problems with a customer trying to use Image magick. The convert binary doesnt seem to be working for him since we installed CageFS.
Also zend optimizer isnt working either. Pages come up with "Zend optimizer not installed".
Using PHP 5.2.17. Zend Optimizer v3.3.9
Anyone else experienced any problems with those?Last edited by Draytoc; 06-01-2012 at 06:46 AM. Reason: sp

ImageMagick -- most likely it was installed from source in some custom directory. You would need to add it:http://www.cloudlinux.com/docs/cagef...s_template.php
Zend -- probably something similar
Please, contact our support at helpdesk.cloudlinux.com (it is free), and they will help you set it up.Igor Seletskiy

Thanks for your reply.
I've checked the imagemagick.cfg file and the paths are correct. It's a cpanel server.
/usr/share/cagefs-skeleton/usr/bin/convert looks fine.
The customer with the Zend problem is using Joomla with some sort of Zend module. Zend was compiled with EasyApache.
I'll drop by your support helpdesk at some point later today.

Were about to put this in to production tonight,
when we run /usr/sbin/cagefsctl --enable-all would we expect to have any problem? ie when others ran this to enable it for all customers, did you get any tickets/problems or anything that would no longer work?█ The Hosting Heroes Ltd - over 20 years in the UK hosting industry.

Hi Chris,
Did you resolve those issues? No one else reported anything like that - so I want to be sure it is resolved on your servers.Igor Seletskiy

Is this just an advanced jail? Why is CageFS better than any other jail out there?

Yes, it is basically a jail.
The main differences are:
1. We provide "virtualized" /etc, where everything is present, but the info about other users.
2. We remove all the SUID software from the jail, yet users still can do passwd, sendmail and other suid based, allowed scripts (via proxy exec).
3. It is inside namespace, not just chroot
4. We virtualize /proc filesystem (one user cannot see processes of other users)
5. It works for web, not just shell/cron
It has all the tools around it to add/remove users, applications, handle updates, etc...
The goal is to prevent privilege escalation as well as information disclosure attacks.Igor Seletskiy

issue a) we just set a task to delete the files every hour.
issue b) Yes we got it back online, it didnt happen on any of the others so i think it was a server issue that just happened at the wrong time.
this is the main reason we installed cageFS :-)█ The Hosting Heroes Ltd - over 20 years in the UK hosting industry.

Are there any performance issues with CageFS?
Let's say you're running a server with 500 cPanel accounts.
Can installing CageFS break anything or cause a server to slow down?

I doubt it will slow it down, we've not noticed any speed reductions, with the better security it brings it'll likely improve things if anything.
