[How-To] Sane Scanner-Server with XSane Frontend

[ram32]

Hi,



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

Oliver

Maybe you can share some thoughts so I can help you too

Hi,

problem with epson2-backend:

Please try the following on a Linux mashine (Ubuntu e.g.)
On the command line type:

SANE_DEBUG_NET=10
xsane 2>net.log

and post thge logfile.

Network scanning?
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 ?

Could you also please try to scan a image on Ubuntu with scanimage?
I think the problem is related to xsane with epson2-backend because like ram32 told us, scanimage works.
Please also try to scan with scanimage from Windows.

If my suspicion is right, I have to ask the developer of XSane if he has an solution.

Only for testing: Comment the line

epson2

and uncomment the line

epson

in:

/opt/etc/sane.d/dll.conf

Restart and try again.

Oliver

[net]

It only seems to be the auth problem, but when I put my login, password and backend in saned.users file on router, and xsane prompts me for login/pw, there is the same segmentation fault...
I even tried strace xsane, but it didn't give it to me any clues.
Also, with epson backend (not epson2!), the scanning module in my RX640 all-in-one cannot be recognized. It seems that this scanner is not supported by epson backend (it is supported with epkowa backend however, but this backend doesn't included in sane-backends package).

[carterb]

Hi,

no that should not be the problem.
Please try with epson2-debug instead and post the logfile.

SANE_DEBUG_EPSON2=128 
xsane 2>ep2.log

I need all these logs with epson2 entry uncommented and epson commented!!!

Regards
Oliver

Hi carterb,
here is the log:

P.S. Done

[carterb]

Hi,

oh sorry, it will not work in that way. Please do the following on your routers command line:

killall xintd
SANE_DEBUG_EPSON2=128 saned -d128 2> /tmp/epson2.log

Now on your computer start XSane and wait for a minute.
After that, go back to your routers command line and type:

Ctrl + c

to stop the sane server.

Post the log file. Please attach it to your post, don't paste the lines

Regards
Oliver

[ram32]

Now on your computer start XSane and wait for a minute.

I can not wait, because it gives me segmentation fault

[carterb]

Hi,

how did you install XSane on your Ubuntu?
What version do you use.

Regards
Oliver

[ram32]

It was installed by default, version 0.996.

[carterb]

Hi at all,

NEWS about sane-backends:

Since I am official Maintainer of the sane-backends optware package, you should use the optware package of sane-backends now.
I will update the package with every revision.
The HowTo is updated for use with the optware package

For all people who have my old version installed (zip-File from rapidshare), please uninstall this version and install the one from the optware-server.
The old version will not get supported by me anymore:
Just do a:

ipkg remove sane-backends
ipkg remove sane-backends-wl500

And install the optware-package like its explained in the How-To.


Regards
Oliver

[carterb]

Hi,

@ram32: At this moment I have no idea what could be the reason for the problem with epson2. I have asked the developer of XSane and also the sane-devil-mailinglist. I will post as soon as I get answer.

Regards
Oliver

[carterb]

Hi,

@ram32: Please update to the optware-version of sane-backends and try again.

Regards
Oliver

[ram32]

Hmm, strange. I removed previous sane-backends installation, installed it from optware, configured it, and now I've got:

[admin@WL-001FC642402C root]$ sane-find-scanner 
sane-find-scanner: can't load library 'libieee1284.so.3'
[admin@WL-001FC642402C root]$ scanimage -L
scanimage: can't load library 'libieee1284.so.3'

[carterb]

Hi,

ipkg install libieee1284

will help!

I updatet the How-To, Thanks for this information

Regards
Oliver

[ram32]

Wow! It works!
Great thanks to you, craterb!
But what was wrong with previous version of sane-backends ipkg?
