[sane-devel] scanner is no longer recognized over network

[Seb]

Hi,

My partner is about to strangle me because she can no longer scan on our
Canon Pixma MP150.  Following updates to Debian sid SANE packages
several weeks ago, this scanner is only seen on the machine with the
server.  We have 3 computers in a home network (on a router):

192.168.0.100
192.168.0.101
192.168.0.102


The SANE server (saned) is on the last one, and in that computer I have
/etc/sane.d/net.conf:

[::1]
localhost


/etc/sane.d/saned.conf:

192.168.0.100/24
[::1]
localhost


/etc/services does include the line:

sane-port	6566/tcp	sane saned	# SANE network scanner daemon


/etc/inetd.conf also has the line:

sane-port	stream	tcp	nowait	saned:saned	/usr/sbin/saned saned


In this computer I get:

However, on the other computers with the clients I get:

I'd really appreciate any pointers.
