The only messages stored by ejabberd for later delivery are messages sent to an offline contact: they are stored, and sent to the contact when he comes back online.</p> <p>You can install a packet sniffer like Wireshark. Listening in localhost 'TCP port 5222', and check what's going on there. Wireshark can recognize XMPP traffic.</p> <p>You can also try mixing a normal desktop client (Gajim, Psi, Tkabber...) and your JS client: send, receive.</p> <p>If you progress in your investigation and consider the problem looks to be in ejabberd, please try to write 'reproduction instructions: install ejabberd x.x.x, create account test1 and test2, login in test1 with the jabber client X version X, ...' This way we can reproduce the problem, and debug ejabberd internals in a controlled environment.</p> Thu, 29 May 2008 23:12:23 +0000 mfoss comment 53209 at https://www.ejabberd.im
