Hi,
I have a domain, let’'s say my.example.com and a friend has another domain, say his.example.net. We both run Wildfire servers. We both want MUC to work.
I can connect to a room on his.example.net, like room@conference.his.example.net but he cannot connect to a room on my.example.com and get’'s a 404 error. But I can join join room@conference.my.example.com with other users of my.example.com.
his.example.net and conference.his.example.net both have A records in DNS as well as matching PTR records. For my.example.com, I have both A and SRV records but I do not have matching PTR records.
his.example.net uses an SQL database for users and allows in-band registration, my.example.com uses PAM and does not allow in-band registration.
Otherwise, we are setup pretty much the same. Neither of us have changed many of the other options. We can do regular chats back and forth so the firewalls are definitely allowing xmpp-server traffic.
What the heck could be going wrong? I have been maintaining the same config file and internal database for a while across many upgrades so it is possible I did something in the config a while ago that is non-standard, but I can’'t see what it might be. Any help would be greatly appreciated.
Hey archangel,
Have you tried enabling the debug log to gather more information? BTW, XMPP requires SRV records to locate remote entities. Anyway, if no SRV record was found then Wildfire will try to open a connection to conference.his.example.net and if that fails then it will try again using his.example.net.
Let us know the new information you found in the logs.

I’‘m not seeing anything in debug info. I put a mark in, tried connecting, nothing. I don’‘t know about his.example.net though, that’‘s just the debug log on my.example.com. I’'ll try to get his as well.
I also want to clarify how SRV records are used. My domain, my.example.com, has a SRV record for xmpp-server.tcp. Is this “the” record for s2s communication? How are SRV and A records used in MUC? Do I need an A record and SRV record for conference.my.example.com?

Hey archangel,
XMPP core specification specifies that SRV lookups should be executed to
identify the real IP and ports to use when connecting to any remote XMPP
entity (e.g. remote server or remote service). A records are not
actually being used but it has been discussed about the idea of using
TXT records as a fallback method when there is no SRV record. Wildfire
currently only performs SRV look ups and if that fails then a connection
to the intended domain on the default port will be used.
Moreover, Wildfire has a unique feature where recursive lookups are done
if the initial connection to the domain failed. This means that if
Wildfire is asked to connect to conference.jivesoftware.com and that
fails then it will try to connect to jivesoftware.com. And if
conference service is being provided by jivesoftware.com then things
will go fine. This novel approach tries to provide a practical solution
for all those installations where SRV records are not being created for
each hosted subdomain/service.

Debug log from his.example.net:

Okay, and the service records for any services are xmpp-server? So I should have
xmpp-server.tcp.conference.my.example.com 0 0 5269 host.my.example.com
Yes. That is basically correct. – Gato
