Hi everyone.
I'm trying to setup Sylkserver as xmpp gateway to connect a Kamailio sip
network with a xmpp network.  I tried last week with gmail, but I was
recommended in this list to install my own xmpp server.

I installed ejabbed, but it still doesn't work.  These are the logs when I
run sylkserver with the --no-fork option, and I try to add a sip account
from a xmpp account:

Starting factory
<sylk.applications.xmppgateway.xmpp.server.DeferredS2SClientFactory object

/etc/resolv.conf changed, reparsing
Resolver added ('8.8.8.8', 53) to server list

[xmppgateway] 0 SIP --> XMPP and 1 XMPP --> SIP presence flows are active
[xmppgateway] Presence flow 0x4806bd0 ended xmpp:prueba at server.ikono.co -->
sip:test8 at ikono.co
[xmppgateway] 0 SIP --> XMPP and 0 XMPP --> SIP presence flows are active
Incoming connection 0 from u'server.ikono.co' to u'ikono.co' disconnected


En xmpp_trace.log aparece:

2013-07-31T11:20:49.444656-05:00 [sylk-server 47599]: RECEIVED: Packet 22,

This is the notifications log.  The DNSLookupDidFail appear periodically in
the log:
