Hi All,
I am looking for the best practices for remotely managing 1000+ linux machines.  The flavor of linux will be either RedHat or SUSE.  I'm not sold on one or the other yet.  These machines will all be sitting at different locations, most of them not with statically set IPs nor firewalls.  My thoughts are to have an ssl client vpn load on boot and hook into my backend (doesn't exist yet).  Then have statically set internal 10.x IP addresses for each of the machines.  I am open to any ideas or products that you know of and I am starting from scratch.  I am highly concerned with conserving bandwidth with these devices and would only be using this vpn for dns requests and remote management. Please let me know any information that you need.

Probably you want system monitoring too (maybe some statistics) too?
Nagios, Big Brotther, MRTG, CACTI etc.
Groundwork extended this to also include statistics & management.  (http://www.groundworkopensource.com/)

Redhat also has a free Clone (CentOS) so you can mix systems that need a service contract get RedHat, and testing/play environments get CentOS.
If using tunnels there's
Also plan ahead on the desktop, gnome is kind of minimalistic approach to a UI,
KDE shows everything, but can be locked down with a kiosk tool.
KDE is less allien for a windows user.
All Gnome software also tends to work on KDE, but not all KDE software will just run using gnome.
