How can I check that? Other than the /etc/inetd.conf line I showed, I have included the saned user in the scanner group (Debian creates a saned user and group). I also included my users in the scanner group, so I don't know where the permissions problem is. Thanks. -- Seb
[sane-devel] scanner is no longer recognized over network
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/tcpsane 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: ---cut here---start-- $ SANE_DEBUG_NET=255 scanimage -L [sanei_debug] Setting debug level of net to 255.

[sane-devel] scanner is no longer recognized over network
[update] I changed the clients' /etc/sane.d/net.conf to point exclusively to the IP address of the SANE server: 192.168.0.102 and now the clients detect the scanner, but cannot use it: ---cut here---start-- $ scanimage -L device `net:192.168.0.102:pixma:04A91709' is a CANON Canon PIXMA MP150 multi-function peripheral $ SANE_DEBUG_NET=255 scanimage -d 'net:192.168.0.102:pixma:04A91709' /tmp/test.pnm [sanei_debug] Setting debug level of net to 255.
