Hi,
After you resolved this problem, I dicided to move this thermometer to a
routerboard. I thought it won't be hard, but it was a mistake.
I've installed an openwrt to a routerbord rb433ah, and prepared for
owfs. (Installed the packages needed like fuse, owfs etc)
I've disabled of course the serial terminal access by comment-out the
/bin/ash line in the inittab:
root@OpenWrt:~# cat /etc/inittab
::sysinit:/etc/init.d/rcS S boot
::shutdown:/etc/init.d/rcS K shutdown
#ttyS0::askfirst:/bin/ash --login
After it , seemed to be working, but not really. In the mountpoint
directory appeared some other owfs related subdirs, but not the sensor
related "3B.xxxxxx.." directory.
When I was running owfs with --debug, that showed this:
************

Then I've installed every avahi* packages, and this debug list haven't
changed. I made a soft-link (libavahi-client.so) to the
libavahi-client.so.3.2.9 (even though I don't think this avahi lib
loading failure correlated to this error) and the debug list became to :
