<P>
<EM>&gt; &gt; thanks, it worked. how do you set it to take a range of hosts or any host?
</EM><BR>
<EM>&gt; &gt; As far as I know that is not supported and I think it also is no good idea.
</EM><BR>
<EM>&gt; &gt; Add each hostname.
</EM><BR>
<P><EM>&gt; I strongly disagree. I wish wildcards were available: *.astro.umd.edu
</EM><BR>
<P>Hmm - is it really useful to have more than a few boxes that are in close
<BR>
physical proximity to the scanner (or is it a camera ? ... hmm for cameras
<BR>
it might make sense) there ?
<BR>
<P><EM>&gt; or at least netgroups. Without them it is so much trouble to list all of
</EM><BR>
<EM>&gt; the hosts for a lesser used function like network scanning
</EM><BR>
<P>Note, that you are giving access to a function that might compromise system
<BR>
stabilty. I do know, that there are some conditions under which at least
<BR>
the Mustek driver locks up the machine hard for me. They are very hard to
<BR>
track, as they leave no traces on the disk due to the hard lock, which is
<BR>
why I didn't fix them yet.
<BR>
<P>BTW: Adding a netgroup is as simple as:
<BR>
a=0; while [ $a != 256 ] ; do echo &quot;192.168.42.$a&quot; &gt;&gt;net.conf; a=$[a+1]; done
<BR>
<P>However IMHO we should rather finally make use of the authentication scheme
<BR>
that is built into sane and allow to scan using usernames and passwords
<BR>
instead of IP-based security, which is a bad thing anyway.
<BR>
<P>CU, ANdy
<BR>
