Hello List,
I have a strange problems. I shared a scanner on one machine. I do not
get access from another machine, but locally over net backend.
connecting from remote makes saned (running as root) segfault:

I previously tried an older sane release on both machines, also an older
c-library, with the same result as above.
Thanks for any help or hint.
Regards,
Paul
