Title: JavaSMFBackup as a "daemon" on a server with no "desktop"?
Post by: sxxxe83 on October 20, 2008, 11:55:30 pm

Hi,

Nice app you have. Works great on windows machine. But on the linux server itself I got some error messages.

This is an debian etch server with no "Desktop/GUI". Or im I just missing something?

Hi,

You are right, the app does not work without a GUI... As it never crossed my mind to keep it running as a daemon, the GUI part cannot be disabled.

I will add this to the list of enhancements, thank you for letting me know!

Sure!

Maybe you can install tightvnc + some basic window manager - and run the application there. But I don't know if the VNC session will remain active after you disconnect.
The fonts will probably look ugly also.

If you try, please post back with the results.

Thanks,
