[sane-devel] Problems with remote scanner.

[Daniel Munoz]

Hi Everyone.

I have a problem with a remote scanner. This is my scenerio:

I have a localnetwork at home. Two computers. The server is running Fedora 6 
and the client is running ubuntu 8.04.

The server has a HP all-in-one printer/scanner. Both are working on the 
server.  I have been able to configure the ubuntu computer to use the remote 
printer, but not the scanner.

On the Server I configured the following:

1. Installed xinetd and created a file in xinetd.d called saned with the 
following:
# default: off
# description: The sane server accepts requests
# for network access to a local scanner via the
# network.
service sane-port
{
port        = 6566
socket_type = stream
wait        = no
user        = saned
group       = saned
server      = /usr/sbin/saned
}

2. In /etc/sane.d configure the following files:
2.1 saned.conf -> added the IP of ubuntu machine: 192.168.1.3
2.2 net.conf -> added hostname of the server -> www.karinasoft.com

After doing that I restarted xinetd and run the command scanimage -L and these 
is the result:

[saned at karinasoft sane.d]$ scanimage -L
device `hpaio:/usb/Deskjet_F300_series?serial=CN6AEGZ16X04KH' is a 
Hewlett-Packard Deskjet_F300_series all-in-one
device 
`net:www.karinasoft.com:hpaio:/usb/Deskjet_F300_series?serial=CN6AEGZ16X04KH' 
is a Hewlett-Packard Deskjet_F300_series all-in-one
[saned at karinasoft sane.d]$   

So the xinetd is working OK, and showing the scanner on the net.

But when I try to run that command from the ubuntu computer, I cant see my 
scanner. So I debuged and these is what Its been shown:


Server:

The server is closing the connection to 192.168.1.3 even when its on the 
saned.conf file, so now I dont know what to do.  Any help will be apreciated.

Si se humillare mi pueblo, sobre los cuales ni nombre es invocado, y oraren,
y buscaren mi rostro, y se convirtieren de sus malos caminos;
entonces yo oiré desde los cielos, y perdonaré sus pecados, y sanaré su 
tierra.
