SANE
Thank you to jaysee (IXUS) for his patience and help to the SANE's configuration
Before installation, go to http://www.sane-project.org/sane-supported-devices.html to see if your scanner is supported.
On sme 7.3 the SANE's version is 1.0.14. (I compiled sane-1.0.17 for sme 7.3. There are many more drivers available. It will soon have a link here.)
Supported scanners
For a list of supported scanners have a look at this page.
Installation
To install SANE login to the SME Server shell as root and issue the following command:
yum install sane-backends
After succesfull installation issue the following commands:
signal-event post-upgrade signal-event reboot
Finding your scanner
After installation and reboot you should be able to find your scanner with the following command:
sane-find-scanner
The output should look like this:
# No SCSI scanners found. If you expected something different, make sure that # you have loaded a SCSI driver for your SCSI adapter. # Also you need support for SCSI Generic (sg) in your operating system. # If using Linux, try "modprobe sg". found USB scanner (vendor=0x04b8 [EPSON], product=0x010f [EPSON Scanner 010F], chip=LM9832/3) at libusb:001:002 # 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.
Determining assigned driver
To see which hardware location is assigned to the scanner issue the following command:
scanimage -L
The output should look something like this:
device `plustek:libusb:001:002' is a Epson Perfection 1250/Photo USB flatbed scanner
If a driver is found, you can continue the configuration, otherwise make following order to remove the rpm : sane-backends
yum remove sane-backends
(First) aquisition
To make a test scan you can issue the following command specifying the driver you determined in [SANE#Determining assigned driver].
scanimage -d drivername --format tiff -l 0 -t 0 -x 215 -y 297 > outfile.tiff
Replace drivername with the driver determined in [SANE#Determining assigned driver], e.g.:
scanimage -d plustek:libusb:001:002 --format tiff -l 0 -t 0 -x 215 -y 297 > outfile.tiff
you can see the resolution of your scanner with this command
/usr/bin/scanimage --help | grep -m 1 resolution
For more informations on sane-backends possibilities:
man sane
Adding your scanner to the network
saned is the SANE daemon. It gives an access to the image acquisition device available on the local host to remote clients.
Updating of /etc/hosts.allow for sane
Make in /etc/ hosts.allow a line with template-custom
mkdir /etc/e-smith/templates-custom/etc mkdir /etc/e-smith/templates-custom/etc/hosts.allow/
nano /etc/e-smith/templates-custom/etc/hosts.allow/saned => saned: 127.0.0.1 10.97.1.0/255.255.255.0
(10.97.1.0 => your ip)
/sbin/e-smith/expand-template /etc/hosts.allow
Updating of /etc/services for sane
Make in /etc/services a line with template-custom
mkdir /etc/e-smith/templates-custom/etc/services/
nano /etc/e-smith/templates-custom/etc/services/saned => sane 6566/tcp # SANE network scanner daemon
/sbin/e-smith/expand-template /etc/services
Add the IP addresses of the computers which are authorized to use the scanner
nano /etc/sane.d/saned.conf => localhost adress-ip_customer1 adress_ip_customer2
Installation and configuration of SANE TWAIN drivers on windows platforms
Installation of SANE TWAIN drivers
In download section, take the ZIPfile (sanetwain127.zip or Windowsinstaller (setup127.exe)
make :
setup127.exe
CONFIGURATION
- index connection Hostname => address ip server Port => 6566 Username => user’s name
I made : Get list of devices on startup
- index printer I made : Show printer setup dialog before print (I have several printers!)
- index Startup I made : Acquire preview on program start Use as interface language => fr
Usage
SANE TWAIN drivers have many possibilities. SANE TWAIN drivers can be used alone or called from another application (photoshop, acrobat, ...) like a classical usb scanner.
First test on network
Start a terminal on your server (with putty for example). make :
saned -d128
example
# saned -d128 [saned] main: starting debug mode (level 128) [saned] main: trying to get port for service `sane-port' (getaddrinfo) [saned] main: "sane-port" service unknown on your host; you should add [saned] main: sane-port 6566/tcp saned # SANE network scanner daemon [saned] main: to your /etc/services file (or equivalent). Proceeding anyway. [saned] main: [0] socket () using IPv4 [saned] main: [0] setsockopt () [saned] main: [0] bind () to port 6566 [saned] main: [0] listen () [saned] main: [1] socket () using IPv6 [saned] main: [1] socket failed: Address family not supported by protocol [saned] main: waiting for control connection
If you have “waiting for control connection “, all sounds good. Now on your windows computer, open Scanimage (name of gui software for sanetwain)
The scanner should start and lines should appear in the terminal (putty)
On the first connection, it often takes a long time and a message like this can appear: Time out reading word from socket Close Scanimage... saned must close up under putty (else ctrl+C to close saned and to come back to the prompt)
Restart ' saned - d128 ' on the terminal and open Scanimage one more time, it should scan! Lines are displayed on the terminal with putty. (type -d for debug mode)
Now automatize the saned startup
If xinetd is not installed :
yum install xinetd
Updating of /etc/xinetd.conf for sane
Make in /etc/xinetd.conf a block with template-custom
mkdir /etc/e-smith/templates-custom/etc/xinetd.conf/
Create a users group where users are going to use the scanner I add a group, saned, with server-manager.
nano /etc/e-smith/templates-custom/etc/xinetd.conf/20sane-port
=>
{
$OUT = <<HERE;
service sane
{
port = 6566
socket_type = stream
protocol = tcp
user = root
group = saned
wait = no
server = /usr/sbin/saned
}
HERE
}
/sbin/e-smith/expand-template /etc/xinetd.conf
Make a link to allow xinetd to start during the server startup
ln -s /etc/init.d/xinetd /etc/rc.d/rc7.d/S50xinetd
/etc/init.d/xinetd restart
The first time, I didn’t succeed to use the scanner on my windows computer when using sanetwain
=> outdated delay of wait..
I resolved problem by changing the file /etc/sane.d/dll.conf
I put in comment (# in front of the line) all lines which did not correspond to my driver.
With MacOS X plateform
There would also be the possibility to use sane.
It has links on the sanetwain site => http://www.ellert.se/twain-sane/
To test...
I doesn’t have a mac
With linux platform
It’s necessary to install xsane (already installed on my pc).
It’s enough to configure xsane so that it achieves the scanner on the server.
nano /etc/sane.d/net.conf (sur le pc client) => address-ip_server
You can use xsane or make the acquisition from a software (openoffice, gimp, ...)
