[Spacewalk-list] Problem register the first client

[Carlo Filippetto]

Hi,
I'm tring to register the first client to spacewalk server, this is my
configuration:

SERVER:
 - CentOS release 5.7 (Final)
 - spacewalk 1.6 with postgress

CLIENT:
 - CentOS release 5.4 (Final)

I follow the documentation on
https://fedorahosted.org/spacewalk/wiki/RegisteringClients, when I
tried to connect the servers I receive this:

[root at server1 instal]# rhnreg_ks --serverUrl=http://10.11.12.13/XMLRPC
--activationkey=123456790aA
Errore: Server Non disponibile. Riprovare più tardi.


What does it means?
What I havo do to?

Thank's
