I'm trying to use a parallel port in Ubuntu with an XP guest but am constantly getting the error you see in the screenshot for /dev/lp0 and /dev/port. (One at a time.) I've tried adding lakeview and root to the lpadmin and vboxusers groups then relogging on and also this:
lakeview@Server:~$ /bin/ls -l /dev/lp0
crwxrwxr-x 1 root lp 6, 0 2008-06-12 22:48 /dev/lp0
lakeview@Server:~$ /bin/ls -l /dev/port
crwxrwxrwx 1 root kmem 1, 4 2008-06-12 22:47 /dev/port
lakeview@Server:~$
which I do plan on changing for security issues once I've tracked down the problem.
Why:
The computer is a file server for a photography studio and ran the security system for a indoor storage place in the basement. The only problem was Windows kept restarting and being unable to automatically log back on with a password set, would shutdown the entry system locking customers out. We decided to switch to Linux because of the flexibility with Samba and mdadm and to help with the basement but Wine doesn't cut it with the security system software so now we have a separate Windows computer running the basement while I struggle with a virtual machine to take its place.
The idea is to hide the virtual machine from the outside world using NAT so it can be left unsecured and be free to crash/restart itself all it wants. Even if it doesn't restart properly, there is a Linux host running which I can log into remotely and fix the problem without driving into town. (BTW, if you see a flaw in my cunning plan let me know.)
