Net scanning

I'm trying to set up a system to do scanning over the net, for the Linux
Demo Day coming up this Sunday the 12th. I have a Mustek that works fine
when used on the machine it's connected to.

I attached it to a 486 with a DTC3181 SCSI card. I can invoke "scanimage"
locally and it works. I *think* I've set things up appropriately for
remote scanning, but so far no dice.

On the local machine, the "net" backend is enabled in dll.conf, as well
as mustek and pnm. My net.conf lists "frakir", the name of the 486.

On the remote machine (with the scanner), "net" and "mustek" and "pnm"
are enabled in its dll.conf, and saned.conf lists "graswandir", the name
of the local machine. The recommended changes have been made to the
services file on frakir:

In /etc/services:
sane 6566/tcp # Scanner daemon

And in /etc/inetd.conf:
sane stream tcp nowait root /usr/sbin/saned saned

(Yes, "saned" really is in "/usr/sbin"). If I try, from grayswandir, to
scan on frakir, I get...

--------------------------
$ scanimage -d net:frakir:mustek:/dev/scanner

scanimage: open of device net:frakir:mustek:/dev/scanner failed
--------------------------

For a while, I had the line in "inetd.conf" wrong (/usr/local instead of
/usr) and the sucker would seg fault on me. Now, it just fails. So it
appears that I'm contacting frakir.

Anyway, where am I being stupid?

Sincerely,
