Every QNAP is different so adapt...

After long searching and trying i have got sane working on my qnap TS209 pro

Sane is a project to use an usb or scsci or parralell port scanner on a server and acces it with other computers over the network. In fact the same like a printerserver. That's why i post it here.

FIXED:
I have got it working but i have still a problem to start it automatically. I edit the autorun.sh script for starting de xinetd but it doesn't start at boot. When i start it manaually sane backend server start but it gives still a error. I used the name : admin and for the group : admin . The error comes for the group, Still don't know why but i'm looking for it. FIXED

All what you need is installing Qpkg on your qnap.
then install sane-backends and xinetd, configure it for your network.
Then i searched for a frontend: I used Xsane, that is supported for windows.
you have to configure it also in the same way as for Qnap NAS.
Then you can have acces to your scanner.
When more people like this feature maybe i will consider to write a tutorial when i have the time.


NOTE: I DON'T TAKE ANY RESPONSIBILITY IF SOMETHING GOES WRONG WITH YOUR DEVICE OR IF YOU LOOSE DATA.

First of al i installed QPKG. I will not explain how to do that because you can find all that information here on the forum.
On some systems like the QNAP TS210 i get an error after install when using the ipkg command:
Result:

[~] # ipkg list '*xinet*'
-sh: ipkg: command not found

Solution:
run this command:I use telnet to login my qnap.

export PATH=$PATH:/opt/bin:/opt/sbin 

I use telnet to login my qnap. You can find that in system tool , remote login. If you use windows xp or any other windows version change the port to 23.

Note: people that use windows vista or windows 7 beta.
Telnet is not standard available anymore you have to install it first.
So open a windows command window in Vista or windows 7 and type this code.

pkgmgr /iu:TelnetClient

Now you can use telnet in Vista and windows 7

for the people that don't know how to login to your NAS by telnet:

open a windows command prompt an type:

telnet 192.168.1.102

where 192.168.1.102 is the IP adres of my Qnap device
it will ask you after password and login and these are the same like administration password when you login via Webinterface


Older Firmwares:

 Raid1 :Newer Firmwares path is :Normal:Raid1 :you need 2 ipkg software pieces. xinetd and sane.

Auto start the config

This method consists in declaring a dummy QPKG which lunch your script at startup.
Log into your QNAP device using SSH or Telnet, for instance by using Putty
Edit QPKG config file:

# vi /etc/config/qpkg.conf

Declare a new dummy package by adding something like that in this file:

[autorun]
Name = autorun
Version = 0.1
Author = neomilium
Date = 2013-05-06
Shell = /share/MD0_DATA/.qpkg/autorun/autorun.sh
Install_Path = /share/MD0_DATA/.qpkg/autorun
Enable = TRUE

As you can see, Shell is the interesting variable: at boot-time, QNAP OS will lunch each QPKG's Shell variable content.
Note: if your NAS does have /share/MD0_DATA (ie. is a one-drive NAS), put the right directory into Shell and Install_Path variables and adapt next commands to your needs.
Create the dummy package directory:

mkdir /share/MD0_DATA/.qpkg/autorun

Create the autorun script with the content of your choice:

...

/share/HDA_DATA/optware/opt/etc/xinetd.d

Raid1 :

/share/MD0_DATA/optware/opt/etc/xinetd.d

Newer Firmwares path is :

cd /share/HDA_DATA/.qpkg/Optware/etc

Normal:

/share/HDA_DATA/.qpkg/Optware/etc[/code

Raid1 :

/share/MD0_DATA/.qpkg/Optware/etc[/code

you need 2 ipkg software pieces. xinetd and sane.
With this code you can find all the software that contains xinet in the name:

ipkg list '*xinet*'

Result:

xinetd - 2.3.14-9 - Highly configurable, modular and secure inetd
Successfully terminated.

With this code you can find all the software that contains sane in the name:

ipkg list '*sane*'

Result:

sane-backends - 1.0.21-1 - SANE is a universal scanner interface
Successfully terminated.

Install this 2 packages:

ipkg install xinetd
ipkg install sane-backends 

If you get an error about md5sum mismatch like this:

Installing xinetd (2.3.14-9) to root...
Downloading http://ipkg.nslu2-linux.org/feeds/optware/cs05q1armel/cross/unstable
/xinetd_2.3.14-9_arm.ipk
Nothing to be done
Successfully terminated.
Collected errors:
Package xinetd md5sum mismatch. Either the ipkg or the package index are corrupt
. Try 'ipkg update'.

ipkg update

And try to install again.

Then execute the following command:

[~] # sane-find-scanner

If you get no error then everything is installed correctly. This happens on the older qnap firmwares.
On the newer one you have this output:

[~] # sane-find-scanner
sane-find-scanner: error while loading shared libraries: libieee1284.so.3: canno
t open shared object file: No such file or directory

solution: install libieee1284.

So we check the ipkg list first:

[~] # ipkg list '*libie*'
libieee1284 - 0.2.11-1 - libieee1284 is a cross-platform library for parallel port access.
Successfully terminated.

So we install:

[~] # ipkg install libieee1284

Normally this shouldn't be any problem.
When this is done we need to configure all this.

From now on i only give the foldernames for RAID1 configurations.
So keep in mind if your Foldernames contains HDA_DATA then use this in stead of my examples with MD0_DATA, If you are using older firmware versions also think about the different folder structure

 

Nrowse to the following folder in telnet command window:

[~] # cd /share/MD0_DATA/.qpkg/Optware/etc/xinetd.d

(note HDA_DATA can be different , check your configuration)

create here a new file named : saned it this not yet exist if already exist just open with vi

vi saned

(vi is a text application)

 

type now the following : (note: type first an "I" now you add text)

service saned
{
port = 6566
socket_type = stream
server = /opt/sbin/saned
protocol = tcp
user = admin
group = administrators
wait = no
disable = no
}

save the file : first press few times on the ESC button

then type :

:wq

( w for write, q for exit, note when you open a file an you don't want to save type then :q!)

so now this file is created.


add the following line to /etc/services: (services is not writable so we need to copy it first) NOTE: When you just installed sane there is already a line like this, however when you restart Qnap overwrite again and the line is gone

saned 6566/tcp # SANE network scanner daemon

cp /etc/services /usr/local/etc/services

now you have to edit the copied file:

vi /usr/local/etc/services

I have added the saned service at the end of the file 
Here part of the file:

amidxtape 10083/tcp # amanda backup services
isdnlog 20011/tcp # isdn logging system
isdnlog 20011/udp # isdn logging system

ADD THIS LINE to services file:

# Local services

save the file : first press few times on the ESC button
then type :

:wq

NEXT:
Edit saned.conf: 

cd /share/MD0_DATA/.qpkg/Optware/etc/sane.d

vi saned.conf

My file contains this :

#
# saned.conf
#
# The contents of the saned.conf file is a list of host names, IP
# addresses or IP subnets (CIDR notation) that are permitted to use local
# SANE devices. IPv6 addresses must be enclosed in brackets, and should

#
# The hostname matching is not case-sensitive.
#

#
# NOTE: /etc/inetd.conf (or /etc/xinetd.conf) and
# /etc/services must also be properly configured to start

192.168.1.0/24 #grant access to scanner from network 192.168.1.x

THIS LINE IS ONLY THAT IS IMPORTANT

My netwerk is 192.168.1.0 until 192.168.1.255 so with subnetmask : 255.255.255.0

Change it to you network settings: other example : 10.10.1.0/24 alwasy add /24 ad the end
If you want a bigger mask like 255.255.0.0 then use this : 192.168.0.0/16

save the file : first press few times on the ESC button
then type :

:wq

NEXT: configure Xinetd:
browse to :

cd /share/MD0_DATA/.qpkg/Optware/etc/

vi xinetd.conf

My file:

 log_on_success = HOST PID
 log_on_failure = HOST
 cps = 25 30
}

includedir /opt/etc/xinetd.d

Change the file like above if you are use older firmware versions, on the new this file is already up to date
save the file : first press few times on the ESC button
then type :

:wq 

If you want a bigger mask like 255.255.0.0 then use this : 192.168.0.0/16

Check if the NAS finds the scanner:

sane-find-scanner

result:

[~] # sane-find-scanner

 # sane-find-scanner will now attempt to detect your scanner. If the
 # result is different from what you expected, first make sure your
 # scanner is powered up and properly connected to your computer.

 # No SCSI scanners found. If you expected something different, make sure that
 # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04b8 [EPSON], product=0x080f [USB MFP]) at libusb:00 THIS LINE IS IMPORTANT
2:004
 # Your USB scanner was (probably) detected. It may or may not be supported by
 # SANE. Try scanimage -L and read the backend's manpage.

 # Not checking for parallel port scanners.

 # Most Scanners connected to the parallel port or other proprietary ports
 # can't be detected by this program.
[~] #

Like you can see it recognize my scanner 


You can try to scan a testpage, this doesn't workd for my but with the command scanimage -L you may not recieve any error.
when it does it's not possible to use your scanner:

scanimage -L

Result:

[~] # scanimage -L
device `epson:libusb:002:004' is a Epson RX420 flatbed scanner LIKE YOU CAN SEE NO ERROR HERE
[~] #

I have had many problems with my epson scanner. There are 2 Epson config files. I have searched a long time on internet how to fix that and solution was to disable one of the 2 config files. so after lots of trial and errors i have found it.

if you also have problems with your scanner try to play with this:
browse to:

cd /share/HDA_DATA/optware/opt/etc/sane.d
vi dll.conf

So here a part of the file: (Note ,use PageUP en PageDOWN so scroll in large files.)
