[Morten Sickel]
|
|
<BR>
|
|
<EM>> but if I try to start saned from inetd, xsane comes up, scans for
|
|
</EM><BR>
|
|
<EM>> devices and just dies with a segfault.
|
|
</EM><BR>
|
|
<P>Sounds like the same problem I ran into setting up a scanner server.
|
|
<BR>
|
|
There is a bug somewhere leading to this behaviour. I solved it by
|
|
<BR>
|
|
starting saned with this shell script wrapper, and running it instead
|
|
<BR>
|
|
from inetd:
|
|
<BR>
|
|
<P> #!/bin/sh
|
|
<BR>
|
|
#
|
|
<BR>
|
|
# Call saned with stderr redirected, to avoid strange crash.
|
|
<BR>
|
|
|
|
<BR>
|
|
#export SANE_DEBUG_NET=255
|
|
<BR>
|
|
#export SANE_DEBUG_DLL=255
|
|
<BR>
|
|
#export SANE_DEBUG_HP=255
|
|
<BR>
|
|
|
|
<BR>
|
|
exec 2> /dev/null
|
|
<BR>
|
|
|
|
<BR>
|
|
exec /usr/local/sbin/saned
|
|
<BR>
|
|
<P>My guess is that the code to test if stderr is a socket fails in some
|
|
<BR>
|
|
strange way. (I wrote it, I guess I should know -- but I don't. :-) I
|
|
<BR>
|
|
tried to redirect stderr to a file to find out if anything was written
|
|
<BR>
|
|
to it, but the file was empty.
|
|
<BR>
|
|
<P>I do not understand why this worked for me. :-/
|
|
<BR>
