folks I know this is a lot but!

Running a pie with the new 512 memory, i2c=/dev/i2c-1
With only a monitor connected. ssh connected through a
term session on a mac-mini. I have run
the pi with a keyboard and mouse same results.
Built the sh card on Debian wheezy - 2012-08-08-wheezy-armel-1.img
Installed owfs with sudo apt-get owfs files where placed
in /usr/bin
using a RP12 sheepwalks i2c adapter which has a breadboard
with 5
DS 18S20 temp sensors.
Plan on having the pie run a solar panel system and some
radiant
Heating 24-7
On boot I do get the msg:
[FAIL] Starting 1-wire TCP Server: owserver failed
running the test command:
pi@raspberrypi /usr/bin $ sudo owfs --i2c=/dev/i2c-1:ALL -F -m /var/1-wire/mnt
-a alias.txt
--nozero --allow_other
produces
the results.
pi@raspberrypi /usr/bin $ ls /var/1-wire/mnt
alarm bus.1 mt_floor mt_otside mt_panel mt_waterin mt_waterout settings
simultaneous statistics structure system uncached
pi@raspberrypi /usr/bin $ ls /var/1-wire/mnt/mt_panel
address alias crc8 errata family id locator power r_address r_id
r_locator temperature temphigh templow type
conclusion owfs alone runs alias files loaded in with
subdirectorys and temperature files
Note: one entry per sensor with subdirectorys.
Reboot or sometimes
sudo killall owfs
/////////////
Running the system
/usr/bin $ sudo
owserver -p 4304 --nozero --i2c=/dev/i2c-1:ALL
/usr/bin $ sudo
owfs -F -s localhost:4304 -m /var/1-wire/mnt --allow_other
pi@raspberrypi /usr/bin $ sudo ls /var/1-wire/mnt

//
sudo owhttpd –p 3000 –s localhost:4304 –nozero
runs fine and I can httpd and see both pages for the
sensors.
If I run owhttpd with –a alias.txt I just see one
page.

pi@raspberrypi /usr/bin $ sudo ls /var/1-wire/mnt/10.384A3B020800
address alias crc8 errata family id locator power r_address r_id
r_locator temperature temphigh templow type
note :
1. no
–a alias command
2. the
double entry’s and double bus 0 and 1 in
/mnt but I still have the subdirectory with temps!
it shure would
be nice to be able to use –a alias names!
////////////
pi@raspberrypi /usr/bin $ sudo killall owfs
pi@raspberrypi /usr/bin $ sudo owfs -F -s localhost:4304 -a
alias.txt -m /var/1-wire/mnt
--allow_other
pi@raspberrypi /usr/bin $ sudo ls /var/1-wire/mnt
alarm bus.1 mt_floor mt_otside mt_panel mt_waterin
mt_waterout simultaneous structure uncached
bus.0 mt_floor mt_otside mt_panel mt_waterin mt_waterout settings
statistics system
pi@raspberrypi /usr/bin $ sudo ls /var/1-wire/mnt/mt-panel
ls: cannot access /var/1-wire/mnt/mt-panel: No such file or directory
note:
still double entrys still two buses!
when I use the: –a alias.txt I loose the subdirectory with
the temperature file
sudo owhttpd –p 3000 –s localhost:4304 –a alias.txt
–nozero
runs fine but I can
not see both pages for the sensors
so my 3 questions are:
1. Why on boot up do I get owserver TCP server fail
2. Why the double entrys in the /mnt directory anytime I
use owserver?
3. Why running the
owserver and then owfs with –a alias.txt causes /mnt/mt_panel but no
subdirectory with temperature file
4. If double entrys
in /mnt are normal why dose the –a alias.txt
file work alone with owfs but crates problems if I run
owserver first?
sudo shutdown –h now shows tcp owserver being stoped
so I suspect the startup error on tcp is not a problem?
be nice I have only been in linux for about 3 weeks.
