I want to setup a collaboration server, and I found openfire which, I think, is free. I tried to install in on a Fedora linux box, but I kept getting errors. When I would try to run the service I would get something like "job for openfire.service failed", I looked in the log, and ran systemctl and systemctl had something about "openfire.service failed openfire is an xmpp "
so I googled these things and really didn't find much.
So I started thinking. Does anyone know of other collaboration servers? I saw Zimbra, but I think I have to pay for it.
I even tried to install openfire on a windows 10 pc, but still had problems, and it wouldn't start.
