I’m having trouble getting Openfire S2S working. Some connections (unsecured) work, others don’t (which I assume require TLS).
Hopefully someone can help me with this - I’ve searched already but did not find anything usable.
My setup:
Openfire 3.8.2 on CentOS
CA-signed RSA certificate (StartSSL)
C2S encryption required, no problems there
HTTPS server admin console connection, also no problem. Certificate properly verifies as CA signed.
Unencrypted S2S works as well, ports are available and usable (jabber.at works, jabber.org does not. gmail.com works as well for connectivity with GTalk)
On the S2S screen, none of the connections have a padlock.
Server security is set optional. I tried compression on and off, made no difference.
I guess I must be doing something wrong, but I don’t know what
Any help appreciated.
EDIT:
Strangely enough, creating an alternate account on another Openfire public XMPP server (StartSSL/Openfire), secure connections work straight up with that remote server when exchanging data between the JIDs… Connections established in both directions, Lock is there, no errors or warning in the logs.
I thought it wouldn’t matter what server software people are using - TLS is TLS, after all?
I hope there’s a simple solution to all this. Dealing with certificates is complex enough as it is already without having to deal with interop problems between different server distros
