Just a respons to the -a alias problems and double entrys in the /mnt directory.
I used the sudo apt-get install and it did create owfs in /usr/bin. Had some
problems
with the alias file. Paul suggested I get the latest version of OWFS (2.9p0).
I downloaded it on a new card
Seems all my problems are solved and downloading the file and installing it
from the command line
was a learning experience for me but it placed the files in the directory
/opt/owfs/bin and they appear to
be operating perfectly.
I want to thank Paul and Mick Sulley for their help.
Jim

Paul,
I can't find the EDS008X. Can you tell me where to look?
Thanks,
Peter
P.S.
We all appreciate your great work.

They're new and a little hidden.
http://www.embeddeddatasystems.com/OW-IO-AI8--Octal-Analog-Input_p_207.html
Support just added in the last release. They have several versions,
including 4 or 8 channels and current or voltage, as well as +/- relays.

folks I know this is a lot but!
?
24 Feb 2013
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
10.384A3B020800? 10.5E503B020800? 10.83373B020800? 10.D6263B020800?
10.F83A3B020800? alarm? bus.1???? simultaneous? structure? uncached
10.384A3B020800? 10.5E503B020800? 10.83373B020800? 10.D6263B020800?
10.F83A3B020800? bus.0? settings? statistics??? system
?
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
?
//
?
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.
?
?
