Hello,
|
|
<BR>
|
|
<P> in umax 1220p backend, I'm using ioperm to allow direct i/o to parallel port.
|
|
<BR>
|
|
So xsane, scanimage and xscanimage have to be ran has root, or to have sticky bit
|
|
<BR>
|
|
set. That worries me, since this allow any user to mistakenly orverwrite any files.
|
|
<BR>
|
|
<P> I looked into ppdev, which could be used, but it lacks 32 bits EPP
|
|
<BR>
|
|
i/o support.
|
|
<BR>
|
|
<P> Changing access mode on /dev/port seems pretty dangerous.
|
|
<BR>
|
|
<P> So, is there any way to avoid this?
|
|
<BR>
|
|
<P>Stef
|
|
<BR>
|
|
<P><PRE>
