After a days hard work, I managed to install the sneak preview 6.40 on Linux. Everything is working fine, as long as I am running on the server.
If I want to connect from another computer with the GUI or a URL it showing errors, i.e. host not reached, host not found etc.
This probably has to do with my lack of Linux knowlegde on ethernet interface configuration.
Any help on this issue would be greatly appreciated.
