[sane-devel] still problems from xinetd

[Joerg Napp]

Hello again,

after solving the PATH issue with the AS6E driver I ran into another
problem which prevents saned from being started from xinetd.

Thhe situation is: sane Version 1.0.11, as6edriver version 0.4.9, scanning
from a workstation after runnding saned -d on the linux box works fine.

When I try to aquire a preview (no matter if i try from sanetwain or xsane
runnin on the windows box or scanimage -d net:... from the linux box) the
scanner makes some moves and stops then; on the corresponding client
program an errort message is issued (except for xsane which dies...).

Running tcpdump shows that the debug messages from as6edriver are sent to
the client. Could this be the reason?

I append the results of scanimage and a snippet of tcpdump results. Any
help is greatly appreciated.

BTW: Is this really the right place for this kind of questions or is there
another list?

CU,

Jörg
