Hello Thanks very much for so quick answers.
@Steinar No usually the lost device(s) don't re-appear after restarting owfs and owserver. But it may vary. I have done so much tries and couldn't catch any evidence of doing this or that solve the issue. Now I just wait and the lost device(s) come back by itself. But it's annoying. @Jan, Ok I'll do as you suggest. I've just installed ow-shell because it was not installed on my system. (2.8p15 from Raspbian repo). I now have the commands owdir, owread etc.. I have launched a small script to monitor the 1wire bus. Usually my bus report 7 devices, this script will log the output of the commands "ls /mnt/1wire/uncached/" and "owdir /uncached" when there is no 7 devices. So we'll be able to see if there is any difference between those 2 commands. Thanks for giving this path to follow. Here is my script: #!/bin/sh # 23 Mai 2016 -- Script to check if any device disappear from 1wire bus while : do sleep 5 # check every 5 seconds HOW_MANY=`ls -ld /mnt/1wire/uncached/??.* | wc -l` # On my system this must return 7 when no problem # echo $HOW_MANY if [ $HOW_MANY -eq 7 ]; then : # do nothing else # log the output of "ls /mnt/1wire/uncached " and "owdir /uncached" (filter for devices directory only) echo "==========================================" >> /tmp/LogCheck1wire date >> /tmp/LogCheck1wire echo "======== ls /mnt/1wire/uncached ==========" >> /tmp/LogCheck1wire ls -ld /mnt/1wire/uncached/??.* >> /tmp/LogCheck1wire echo "=========== owdir /uncahed ===============" >> /tmp/LogCheck1wire owdir /uncached | grep 00 >> /tmp/LogCheck1wire # On my system all 1wire devices end with 00 so this lists 7 devices echo "==========================================" >> /tmp/LogCheck1wire fi done By the way here is my kernel info: $ uname -a Linux Box 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux Best regards -- Guy ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
