Hi Ray,<br>
<p>
The only difference to my setup is the use of /usr/bin/in.identd rather<br>
than /usr/sbin/tcpd. As I don't know which files control the access for<br>
the first one, I suggest you try it with tcpd and edit your<br>
/etc/hosts.allow file to explicitly say<br>
<p>
saned : picard.ray.clark.net<br>
<p>
or alternatively<br>
<p>
ALL : ALL<br>
<p>
if you really want to be sure the service is allowed for your client.<br>
Are you sure you didn't get a 'rejected' message when you access the port<br>
via telnet? That could mean that the service is requested by different<br>
users depending if you try telnet vs. xscanimage, and that these users<br>
have different access rights. But why and how?<br>
<p>
Sorry for not being able to help more at this stage.<br>
