Hi,

Well, from the logfiles it's clear that spacewalk<-->spacewalk-proxy connection 
is not working as it should.

Comparing to my logfiles I noticed something strange: bot your nodes when 
logging about dialback report remote peer as 192.168.2.13

Jun 10 09:40:39 spacewalk-proxy jabberd/s2s[10101]: [8] [192.168.2.13, 
port=5269] outgoing connection for 'spacewalk.example.com'
Jun 10 09:40:39 spacewalk jabberd/s2s[20060]: [9] [10.168.2.13, port=5269] 
outgoing connection for 'spacewalk-proxy.example.com'

Can you provide more details about addressing? you can also paste output of the 
following commands:

on spacewalk:
nc -z -v spacewalk-proxy.example.com 5269

on spacewalk-proxy:
nc -z -v spacewalk.example.com 5269

Regards
/Matt

Hi,

- The resolution of both is ok.

I attached logs from spacewalk server, spacewalk proxy and one server behind 
proxy.

Like we can see in log on spacewalk server and spacewalk proxy, it seems that 
teh two servers can't talk to establish jabber "routes" between them :

Objet: Re: [Spacewalk-devel] spacewalk-proxy and osad

Can you make sure both spacewalk and proxy servers resolve each other hostname 
to the right IP address ?

I had a similar problem where the proxy hostname was from a private named 
network so I had to edit /etc/hosts on spacewalk server.

Else, please post log messages from both servers jabber service, and from 
client osad additionally (run using /usr/sbin/osad -N -vvvvv).

Hope it helps.
/Matt

Hi all,
I've already posted that on spacewalk-list but, maybe my problem is just a bug 
in the default jabber server configuration on spacewalk proxy.

We have some problems with osad and spacewalk proxy.
All boxes behind the proxy are seen as offline in osad status on spacewalk 
server, and no action assigned to these machines are picked up. Also, on 
spacewalk web ui, in  "details => connection" section of host behind proxy, i 
can see spacewalk proxy host listed.

We can see boxes connected on spacewalk proxy (on port 5222), the proxy is 
connected on spacewalk server (on port 5222), but we don't see any trafic on 
5269 port from spacewalk-proxy to spacewalk server.

we have iptables firewal between the spacewalk server and proxy and we opened 
80,443,5222,5269 ports from proxy to spacewalk server.

spacewalk server:
CentOS 5.6 x86_64
spacewalk 1.4
SElinux : Permissive

spacewalk proxy:
CentOS 5.6 x86_64
spacewalk proxy installed from spacewalk 1.4 repo
SELinux: Enforcing, with spacewalk-proxy-selinux installed

Regards.
