I am running successfully and without hitches (like there were in the
beginning, that is summer last year) for 4 months continously (without
reboot) my home heating system, but I am not home now, so I cannot check
my settings.
I do faintly remember, that I had to install some driver for ftdi, I am
not sure if this is still required. If you can wait for the weekend, I
can check my setup and config and give further help,
Martin
P.S. read some comments I made below...

Thanks for the quick responses. I am running everything as root, I
have created the mount point directory, and I am using --foreground,
but owserver still exits immediately with no output.
Specifically, here's my /etc/owfs.conf (with comments removed to keep
this message shorter):
error_print = 2
error_level = 9
! server: server = localhost:4304
server: usb = all
mountpoint = /mnt/1wire
allow_other
http: port = 2121
ftp: port = 2120
server: port = localhost:4304
And here's my mount point directory:
root@raspberrypi:~/ow# ls -ld /mnt/1wire
drwxr-xr-x 2 root root 4096 Jun 9 22:53 /mnt/1wire
to run owfs without sudo, you should make the 1wire directory your user
and group
When I run owserver with the following command, it exits immediately
with no output.
root@raspberrypi:~/ow# owserver --foreground --error_print=2
--error_level=9 -c /etc/owfs.conf
root@raspberrypi:~/ow#
I've also checked the log files in /var/log (syslog, messages), and
there are no owserver-related messages in them.
yeah, I think I was wrong earlier, when I thought foreground is doing
the trick - foreground is only not disconnecting from the terminal... sorry
In case it's relevant, here are the messages that show up in
/var/log/kern.log when I first plug the LinkUSB into one of the Pi's
USB ports, showing that system is recognizing the LinkUSB:

again, I can check that on the weekend
Interestingly, if I change the line "server: usb = all" in
/etc/owfs.conf to "server: FAKE = DS18S20,DS2405", the owserver
command above does not exit --- the process seems to run, but I still
get no output on stdout, stderr, or in the log files.
Also, when I run owserver with "--help", it does print the help
message, which shows that the owserver program is definitely installed
and runable:

Do you have any additional suggestions about what could be wrong? I
don't understand why I am not seeing any error output at all.
Thanks again!

error messages go to syslog, unless you specify --foreground (I
hope its written right, check the man page please), in which case
you get all message directly to the terminal and the terminal
stays connected to the daemon.
error-level=9 delivers a LOT of messages! Try a lower number like
2 or 3 to get the essential messages.

Hi,
I'm new to owfs and am trying to use it with a LinkUSB and two
temperature sensors on a Raspberry Pi. I've gotten the owfs
package installed via "apt-get install owfs", and I edited
/etc/owfs.conf according to some examples I've found on the web.
But when I try to run either owfs or owserver, both programs
terminate with no error messages. I've tried setting
error_level=9 in /etc/owfs.conf, and also passing
"--error_level=9" on the command line, to no avail.
Can someone give me a tip as to how I can get owserver/owfs to
give me some error output so that I can get some clues as to what
is going wrong?
Thanks!
