yes. the problem is the file /etc/services that after a reboot changes back to the sane-server instead of saned

**carterb** · 09-10-2009, 18:22

Hi,

then you did not change /opt/etc/init.d/S01sane-backends.
This file looks at startup if the right service/port configuration is in /etc/services.

I changed /opt/etc/init.d/S01sane-backends

Now I have 2 problems.
I change /etc/services to

Code:

# Local services

saned               6566/tcp        # SANE network scanner daemon

but after the reboot it backs to sane-port. How that happens? Is it possible to have some file automatically doing that?

I changed that and instead of rebooting I shut down xinetd and started it again and after that I run the code scanimage -L and I got

Code:

[rmfontes@WL-500gp root]$ scanimage -L
scanimage: '/opt/lib/sane/libsane-hpaio.so.1' is not an ELF file
scanimage: '/opt/lib/sane/libsane-hpaio.so.1' is not an ELF file

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Hi,

libsane-hpaio.so.1

ok thats some problem with hplip-library. I have to figure out how to solve it.

Please post the file:

Code:

/opt/etc/init.d/S01sane-backends

after a restart.

but after the reboot it backs to sane-port. How that happens? Is it possible to have some file automatically doing that?

The reason is a wrong "/opt/etc/init.d/S01sane-backends" because this file is looking for the right entry and if its not in, it will becreated. In your case, "sane-port" is created and not "saned". So as I told you, please post the file.

Regards
Oliver

I checked the /opt/etc/init.d/S01sane-backends file and it was sane-port. I don't know how it changed but it's ok now after the reboot. No error on the xinetd.
The only thing that does't work is scanimage -L.

Hi,

good!

Code:

scanimage: '/opt/lib/sane/libsane-hpaio.so.1' is not an ELF file
scanimage: '/opt/lib/sane/libsane-hpaio.so.1' is not an ELF file

I'm looking for a solution for the other problem.

Oliver

**carterb** · 11-10-2009, 22:24

Hi,

do the following for a test:

Code:

rm /opt/lib/sane/libsane-hpaio.so.1
ipkg remove hplip
flashfs save && flashfs commit && flashfs enable && reboot

After restart do:

Code:

ipkg install hplip

restart and try it again with:

Code:

scanimage -L

Regards
Oliver

**rm_fontes** · 12-10-2009, 21:23

hplip problem solved

scanimage -L still doesn't detect the scanner

**wiert** · 15-10-2009, 23:26

Many thanks for the HowTo!

I followed the whole thing and my Epson all-in-one RX520 is now connected to the ASUS WL-500 g Premium.

What is working:

printing ubuntu Karmic & Jaunty
printing Windows XP
sane-find-scanner detects the scanner
scanimage -L detects the scanner after adding "0x04b8 0x081a" to epson2.conf

I scanned an image (with scanimage) locally on the router and was able to save to the external storage device.

What is not working:
scanning over the network with xsane (Ubuntu and Windows XP)

I double checked with the instructions in the HowTo
what am I doing wrong - have missed something
how to analyse - logs - commands ?

**carterb** · 16-10-2009, 07:43

Hi,

whats the error message of XSane?

Could be a network problem.

After a restart pleaso post the output of the following commands:

Code:

grep "saned" /etc/services

Code:

grep "saned" /opt/etc/init.d/S01sane-backends

Code:

#Restart xinetd
killall xinetd
xinetd -d

Post the complete output of xinetd.

From your Windows-Commandline (cmd), type

Code:

telnet ip.of.your.router 6566

If the output is a black screen, well! Otherwise post the error-message.

Regards
Oliver

Thanks for the quick reply, here my answers:

Output of Xsane: no devices available

Code:

grep "saned" /etc/services

saned 6566/tcp # SANE network scanner daemon

Code:

grep "saned" /opt/etc/init.d/S01sane-backends

if !( grep -q ^saned /etc/services ); then
echo "saned 6566/tcp # SANE network scanner daemon" >> /etc/services

Code:

#Restart xinetd
killall xinetd
xinetd -d

sh: xinetd: not found

Code:

telnet 192.168.1.1 6566

Trying 192.168.1.1...
telnet: Unable to connect to remote host: Connection refused

I suppose a xinetd and/or connection problem? My answers made me thinking:
due to some reason "xinetd" was not installed (not seen in HowTo, forgotten, ...), but

Code:

ipkg install xinetd

and

Code:

flashfs save && flashfs commit && flashfs enable && reboot

Did help me one step further
Now Xsane is starting remotely, but gives the following error:

Unknown SANE status code -1081075667

I'll keep searching?

I tried scanimage both on Ubuntu and Windows and the output of

Code:

scanimage -L

on Ubuntu gives:

WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect
device `net:192.168.1.1:epson2:libusb:003:003' is a Epson generic flatbed scanner

Thx

Hi,

are you sure, xinetd is installed correctly now??

please again (now with xinetd installed) post the output of:

Code:

#Restart xinetd
killall xinetd
xinetd -d

And post your xinetd-sane-file:

Code:

vi /opt/etc/xinetd.d/saned

I'm looking for the error message on sane-support, because I do not know it.

Oliver

Hi,

Part II:
The output of

Code:

#Restart xinetd
killall xinetd
xinetd -d

looks like

Code:

70/1/1@13:19:03: DEBUG: 1662 {handle_includedir} Reading included configuration file: /opt/etc/xinetd.d/saned [file=/opt/etc/xinetd.conf] [line=15]

and my xinetd-sane-file:

Code:

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

}

If nothing wrong with the above output, probably a backend problem?

I had to put manufacturer ID and device ID manually in epson2.conf to let scanimage recognise the scanner?

Thx!

Hello!
Great thanks for you howto, carterb!
But I have the same problem as weirt with my Epson Stylus Photo RX640. The output of all commands are the same as weirt's. Except two things.
1) xsane gave me a segmentation fault.
2) I am able to get scan using simple scanimage > temp.png on my PC running Ubuntu Linux.

2) I am able to get scan using simple scanimage > temp.png on my PC running Ubuntu Linux.

this seems to be a problem with the epson2 backend.
I'm working on a solution.
