Description Joerg Schaible 2011-01-28 19:38:06 UTC

After upgrading sane-backends from 1.0.19-r2 to 1.0.12-r1 on client and server, the scanning over network fails.

==================== %< ===================

It is necessary to downgrade on client and server. AMD64 on client (Core i7) and server (Core i2) with same kernel version.

udev rules have been reread started after each emerge (client and server) and xinit.d newly started (server).

Reproducible: Always

Steps to Reproduce:
1. Emerge new versions on client and server
2. Reread udev rules
3. Restart xinet.d on server
4. Start kscanlite on client
5. Scan over network device


Actual Results:  
Scan is aborted on client and server contains entries above

Expected Results:  
Scan should be performed without errors.

Downgrade to 1.0.19-r2 helps.

Could you maybe shut down xinetd, run "saned -d128" and attach the output of another scan attempt? Thank you!

Is this still a problem with .22-r1?

Comment 5 Joerg Schaible 2011-09-21 23:26:47 UTC

Actually I cannot say. Meanwhile I changed hardware and I have now a Brother DCP-90190CN, i.e. I do no longer need the hplip backend (with proprietary drivers). The sane-backend-1.0.21-r1 for this Printer/Copier/Scanner and scanning over network works flawlessly.

Looks like this was hplip related, cc-ing hplip maintainers.

> Ping! Does anyone who cares for hplip read this?

Unfortunately I can not help here as I do not own the hardware to scan over the network.

Plus, do you really think hplip is at fault when a downgrade of sane-backends to version 1.0.19-r2 fixes it.

Comment 9 Patrick Kursawe (RETIRED) gentoo-dev

2012-01-19 12:15:53 UTC

Sure, it looks unlikely - but if you have a look at the strace logs, you'll see that sane does almost the same stuff in both cases, it's the backend that aborts the scan attempt as far as I interpret it. To me it looks like it is a bug of the backend triggered by slightly different behavior of sane.
No idea how to track this down - given no hardware is available. I'll close this as CANTFIX.
