Woks but the scanner wont, the website said to open UDP Port 54925 in the firewall.

I don't think the problem is with the ports, when i run xsane in root it works
I think i need to find how to give my scanner root access.

Typically Ubuntu has come with all ports open (effectively no firewall).

SANE: Supported Devices

That's not encouraging. I'm still trying to figure out how to look at the Mac driver disk they offer for download, but I don't hold hopes for that either. This is one of those things where lacking source code makes it difficult to make a device work. Lacking a proper backend for the scanner might be a fatal blow.

You will probably find you need to give regular users read/write access to the scanner device. This looks more like a device permissions problem. You may be able to chmod the device to allow regular user access.

Whoops, I see. Okay cool. I was working on this for so long I forgot to check first if anything had happened in the mean time. Doh!

Anyway, AFA the device permissions problem, I got around that problem with my Canon by enabling the net interface for sane. Then when I launch xsane, it gives two identical device names except one is prepended with NET:. The net one is accessible to users.

Not most ideal, but works.

How do i do that, what do i type in terminal?.
tnx

The problem with that theory, assuming that this is a USB device managed by udev, is the permissions change back to default with every boot or device power cycle, or just being unplugged and plugged back in.

chmod 777 /dev/DEVICE gives full permissions to DEVICE to everybody.

If the scanner however is an older parallel port model, just make sure the user is a member of the group lp .

OK sure but what do type in terminal
"root@peter-laptop:/home/peter# chmod 777 /dev/DEVICE
chmod: cannot access `/dev/DEVICE': No such file or directory"
it's a usb scanner/printer MFC 950c

[D-cat]

You have to replace "DEVICE" with the device name/port the scanner is plugged into.. for example, if it's installed as /dev/usbdev2.1_ep(xx), you'd do something like

chmod 777 /dev/usbdev2.1_ep*

Finding out which of your usb devices was assigned to the scanner is another issue by itself. Since it's regularly changing, it's just not worth working this method. You could just run the whole USB gambit:

sudo chmod 777 /dev/usb*

which could make for some instability or security problems within the USB system, and like I said, the "fix" is temporary if it even works.

OTOH, editing /etc/sane.d/net.conf to include a line

localhost

fixes the problem permanently.

if I use Xsane by using
$gksudo xsane
