Problem connecting between 2 servers.

[Daniel Carrasco Marín]

Hi friends, first of all i'm sorry for my english.

I'm trying to create two chat servers, but i've problems with s2s. One of that servers is in Openfire, and the other is in prosody.
When i try to add an user from the other server i get an error, and the prosody log says:

I've tested the connection between both servers with ping, nslookup, telnet server port... and all works fine but i don't know why i get dns error...
I've created two virtual machines with two prosody servers:
-If i try to add an openfire user from virtual machines servers then only works with IP, if i use dns name fails (dns name works and resolve).
-if i try to add an user from prosody server don't works even with ip and from all other servers.
-if i try to add an user between virtual machines works fine.

I've tried with IP and DNS (with virtualhost in config and user created) and don't know what happen...
Connection with users are fine using IP and DNS in all servers. I've seen that the other server was connected to a random port for a while, but fails too.

Someone know what i've to do?

Prosody does not support s2s to bare IP addresses, so this isn't going
to work.

You can use a plugin like mod_srvinjection[1] or mod_s2soutinjection[2],
but the best way is to set up DNS records.

(no docs, sorry)

Edit: I've added an user created in prosody server to an user in virtual machine server and pidgin says that remote server is not found, but if i use netstat in prosody server (the remote server) then i get this:
tcp        0      0 chat:xmpp-server        XXX:49011          ESTABLISHED

The servers are connected but don't works...

Thanks for reply.

I've both servers added in DNS servers, and connection between both server works (ping, telnet...) if i use DNS name, but prosody still fails...
192.168.2.237 = work.ttu.red (prosody)
192.168.2.253 = maruja.red (openfire)

I've tried to add an user to 253 server using us...@192.168.2.237 and us...@work.ttu.red and both fails. I've tried the same in 237 but with us...@192.168.2.253 and us...@maruja.red and fails too.
I've two test prosody servers in virtual machines using 192.168.2.145 and 151 IP's, and if i try to add an user works in both using us...@192.168.2.145 and us...@192.168.2.151... but if i try to add an user from the other servers to a virtual machine server then:
-adding us...@maruja.red fails.
-adding us...@192.168.2.253 works
-adding us...@192.168.2.237 or us...@work.ttu.red fails.

Thanks, maybe i'll try to use that mods.
