[Spacewalk-list] server hw dimensioning and usage questions

[Mgr. Peter Hudec]

Hi all,

few last week I'm playing with this system to fid out, if it's suitable for our purposes.
There are several question, that I have, please help me to answer then.

First, the purpose of usage
HW:	1000x notebooks
SW:	Debian/Ubuntu based

I'm able to install ported packages and register the client correctly with small patches. Manage the repositories, add/remove packages etc ...

1) hw dimensioninig
The testing instance is running on server /KVM virtual/
	RAM:	4GB
	CPU:	1x2.4GHz
	HDD:	20GB
I run small script, that run 1000x registration so see how it will look like. The server is from time to time unresponsive, is this normal ?
Cca 10% of the registration failed due the server problem ;(
Could you please recommend the final HW spec ?
--- cut /script/ ---
for ID in `seq -w 0 999`; do
	echo -n "SystemID: ${ID}"
	echo "HOSTNAME=fo-VirtualBox-${ID}.hudecof"  > /etc/sysconfig/network
	rhnreg_ks --activationkey=1-b22aba199b5543c81d68387aa2d09baf --force	
	echo " ."
done
--- cut ---

2) system hw info history
As the clients will be notebooks, the HDD replacement /form bad HW to new/ could occur. The "Schedule Hardware Refresh" will clean all information
from the DB and insert new one. Is there any way how to store the history of the HW without patching the system?

The main purpose of this is the battery information. I did small patch push within th HW also battery information. I will provide patch against
spacewalk-1.7 to developer mailing list after final testing. Do not know if it will be accepted.


3) system name change
During the registration, the hostname is used as system name. If the hostname is changed, i there any way how to automatically reflect this in spacewalk?


4) spacewalk monitoring function
Could anyone explain me this function and if it works on debian based clients?
I need to get upon request the disk space usage of the notebook. As the notebooks are mobile, the ip address is not fixed, so there is very hard to
use monitoring system.

5) client side certificates
as the clients are mobile do the spacewalk have possibility to verify the connection based on client ssl certificate?
I did not found any configuration directive on 'rhnsd' or 'osad'.


	best regards
