Cannot open server at localhost:4304 #34

Hi, all!

I'm running owfs

/usr/lib/owfs/owfs version:
        3.1p5
libow version:
        3.1p5

Since yesterday I'm I got troubles accessing my Dallas 1-wire sensors read from this "hat" on a Raspberry 3.

This command: sudo /usr/bin/owfs --i2c=ALL:ALL --allow_other /mnt/1wire/ --debug

I have rebooted and also confirmed that I have a i2c instance and restarted all ow* instanced under /usr/bin that I could guess..

What has gone wrong? - This thaw weather can't make it refuse to start (short circut)?

I have rebooted and also confirmed that I have a i2c instance and restarted all ow* instanced under /usr/bin that I could guess.

Actually for debugging you should stop all ow* daemons and keep only owserver running. Moreover, if you are on raspbian, don't start daemon directly (sudo /usr/bin/ow*) but use the appropriate sudo systemctl start ow*.service.

My personal advice: keep it simple, uninstall all ow* packages, and keep only owserver and ow-shell and verify if the owdir shell command lists all your devices.

Thanks miccoli,
I'm sure that's the way to go but don't seem to solve my problem?
I did an unistall and a reinstall of OWFS (All packages) but if I understand you right, I should only install
owserver and ow-shell ?

When installing I used this method:
https://wiki.m.nu/index.php/OWFS_with_i2c_support_on_Raspberry_Pi_(English_version)
But installed with `sudo apt install owfs``
Thanks for your help!

miccoli · 2019-02-20T22:15:25Z

I did an unistall and a reinstall of OWFS (All packages) but if I understand you right, I should only install
owserver and ow-shell ?

Yes, apt install owserver owdir, just to be sure that there are no other daemons accessing the 1-wire bus master; however the important thing is to double check that there are no other ow* daemons running (eg with pstree and killing all running ow* daemons). Then the correct command to start the owserver is

sudo /usr/bin/owserver --i2c=ALL:ALL --debug

Once the owserver is up and running you should run

owdir

from a different terminal.

Nornode · 2019-02-21T06:39:01Z

That worked! No ow* daemon was running and I installed the recommended packages. I can see my sensors running owdir! So why are they not mounted on the place I have directed? What's the dependencies as Domoticz I'm using to read depends on a folder listing (mnt/1wire/). Thanks for the troubleshooting help!

/usr/bin/owfs (the fuse filesystem access to OWFS) is now deprecated: in this regard instructions at https://wiki.m.nu/index.php/OWFS_with_i2c_support_on_Raspberry_Pi_(English_version) are outdated, if not wrong.

I know, docs on ow* are sparse and not well maintained; currently the only official docs are the man pages (man owserver, man owfs.conf) and the old home http://owfs.org.

If I can condense advice in a few words:

if possible avoid the fuse thing /mnt/1wire/: specific instructions depend on your application, but at least for shell programs just change cat /mnt/1wire/26.xxxxxxxxxxxx/temperature into owread /26.xxxxxxxxxxxx/temperature etc.
in Debian derived distros (ubuntu, raspbian, etc.) ensure the daemon is started at boot by enabling its systemd service: sudo systemctl enable owserver.service and do not edit files in /etc/init.d
finally take the time to properly configure the /etc/owfs.conf file. It's a little bit more complicated than necessary, but not that difficult.

A great place for asking for help is the mailing list, https://sourceforge.net/p/owfs/mailman/owfs-developers/: low traffic and usually very friendly.

Hey, coming back a couple of days later trying your advice (and having to write a bash script to out the values in to files) owserver stopped and don't want to start again.
Claiming that ow_com_close is not implemented and it can't detect an i2c DS2482 on ALL:ALL.
(Log output below)

However, I think it's strange as it did work excellently before and my i2cdetect still gives me a proper value on the bus.

This ain't cool to just deprecate a functioning setup!

I'm closing this isse because It has become too old to be still useful.

Unfortunately we are not able to give advice on generic configuration/installation issues on this site.

Sorry for closing and feel free to ask again on the mailing list.
