[sane-devel] Cannot use scanner over network (saned)

[Peter van Heun]

Hello,

I have an Epson 1260 on 192.168.1.3 with Ubuntu 9.10 working. Scanimage 
gives 'plustek:libusb:001:006'. Scanning on 192.168.1.3 works flawless.

I have followed http://wiki.ubuntu-nl.org/community/ScannerDelen (in 
dutch for sharing a scanner in Ubuntu). This worked for me on another 
machine Ubuntu 8.04 and a HP 4400c. But on the 192.168.1.3 with Ubuntu 
9.10 i can not get a connection from another machine for example 
192.168.1.4 with Ubuntu 9.10, neither with SaneTwain under Windows XP.

/var/log/syslog on 192.168.1.3 (with hostname peter-desktop) gives:

Dec 17 22:40:12 peter-desktop saned[8715]: saned (AF-indep+IPv6) from 
sane-backends 1.0.20 starting up
Dec 17 22:40:12 peter-desktop saned[8715]: check_host: access by remote 
host: 192.168.1.4
Dec 17 22:40:12 peter-desktop saned[8715]: init: access granted to 
peter at 192.168.1.4
Dec 17 22:40:15 peter-desktop saned[8715]: saned exiting

after trying to get a list from client 192.168.1.4 with 'scanimage -L'.

When I try to connect directly from 192.168.1.4 to 192.168.1.3 with 
'scanimage -d net:192.168.1.3 -T' I get:

Dec 17 22:45:13 peter-desktop saned[8766]: saned (AF-indep+IPv6) from 
sane-backends 1.0.20 starting up
Dec 17 22:45:13 peter-desktop saned[8766]: check_host: access by remote 
host: 192.168.1.4
Dec 17 22:45:13 peter-desktop saned[8766]: init: access granted to 
peter at 192.168.1.4
Dec 17 22:45:16 peter-desktop saned[8766]: process_request: (open) 
device_list[0] == 0
Dec 17 22:45:16 peter-desktop saned[8766]: saned exiting

In both situations I get:

scanimage: open of device net:192.168.1.3 failed: Invalid argument

on client 192.168.1.4.


In net.conf on the client I have '192.168.1.3'.

In dll.conf on the client I have 'net'.

'telnet 192.168.1.3 6566' from client 192.168.1.4 gives a connection to 
192.168.1.3.

In '/etc/sane.d/saned.conf' on 192.168.1.3 there is 192.168.1.4.

In '/etc/hosts.allow' on 192.168.1.3 there is '192.168.1.4'.

/proc/bus/usb/001/006 has rights '-rw-rw-r--' and user:group 
'root:plugdev'. Changing it to something else do not matter. Using sudo 
in front of any of the commands has the same results.

Anyone have any clue why I cannot connect from client 192.168.1.4 to 
server 192.168.1.3 ?

Thx, Peter
