Thank you for that clear explanation, now I understand the basics at
least.

It would seem that the Ubuntu 'owfs' package sets up owserver plus
owhttpd and owftpd but doesn't by default run owfs.  I think this is
probably what caught me out, I maybe ran owfs manually and then lost
it at a reboot.

Thanks again for all the help and bearing with my questions.

I second that, BUT Chris may NOT use --usb=ALL on any daemon but
owserver then.

Re: [Owfs-developers] Everything is (apparently) running but nothing at /mnt/1-wire

2014-05-08 Thread Stefano Miccoli
Basically you have two options:

1) Run a single daemon  that directly accesses the 1-wire bus, i.e. one of your 
choice between 
owftpd, owhttpd, owserver, owfs
2) Run owserver as a front-end (accessing the 1-wire bus directly) and any 
number of the other programs, accessing the bus via the owserver protocol.

If you chose option 1) you should start only owfs, making sure that no other 
daemon is started. (And modify you owfs.conf file).

If you chose option 2) you should start owserver and owfs, and you may start 
also owhttpd and owftp.
Your owfs.conf file is correctly setup for option 2) and you can start also 
owhttp and owftpd.

I'm sorry but I really don't understand still.

How do I know "if you have any process running which connects directly
to the host adaptor"?  

As I said I only actually *need* to see the results in /mnt/1-wire (or
whatever is defined in the owfs.conf file).  

What isn't clear though is which processes *need* to be started and
which processes *may* be started.  The owfs.conf file I'm using is
basically the one that gets installed when installing 'owfs' as a
package in Ubuntu.  It would appear that there is something wrong with
what Ubuntu installs by default because it seems to start owserver,
owhttpd and owftdp but *not* owfs.

In your explanation above (thank you) are you saying that one can
either install/run one of owfs, owftpd, owhttpd just by itself *or* one
installs/runs owserver and then owfs, owftpd and/or owhttpd run as
'clients' of owserver?

My owfs.conf file is now:-

!server: server = localhost:4304
server: usb = all
mountpoint = /mnt/1-wire
allow_other

http: port = 2121

ftp: port = 2120

server: port = localhost:4304

(I've removed the comments)

This appears to be working with owserver run from /etc/init.d and with
owfs started manually:-

chris@beaglebone$ ps -ef | grep owfs
root 18418 1  0 17:16 ?00:00:02 /usr/bin/owserver -c 
/etc/owfs.conf --pid-file /var/run/owfs/owserver.pid
root 19228 1  0 17:54 ?00:00:00 /usr/lib/owfs/owfs -c 
/etc/owfs.conf

Is this working correctly now?  Do I need both owserver and owfs?  Can
I add owhttpd and/or owftpd?

I'm sorry I seem to be having so much difficulty understanding this
all, what is frustrating is that I had it all working reliably for
some weeks and then it all went wrong (and I didn't think I had
changed anything).

The owfs program is the front-end for fuse.

Any of the programs

owfs
owtftp
owhttpd
owserver
...

and most of the language bindings (all not ownet) are mere frontends for
the underlying owlib. They all link to owlib, which is the actual driver
and controls the bus.

You may start any of these programs separately, and each of it may use
owlib to connect directly to a host adaptor or

*and this is important*

to an owserver on the same or another computer which connects to a host
adaptor on that computer. Think of owserver as a "Onewire over IP Tunnel".


But there is another use for owserver

*and this is important.*

You may *not* connect more than one owlib using process to the same host
adaptor, concurrent access doesn't work reliably on that level. With
USB, you may get the impression it works, but it doesn't. Don't try it,
it's an endless source of frustration. Instead, use owserver to connect
to the host adaptor and connect the other programs to owserver instead.


So check if you have any process running which connects directly to the
host adaptor and end that process before trying to debug anything.


Kind regards

Look at the "server: server = ..." line. IMHO it should be

! server: server = localhost:4304

Hmm, I'm confused.  What I can't work out is why it *used* to work but
it doesn't work now.  

All I actually need to work at the moment is owfs such that the
measurements from my temperature sensors appear in /mnt/1-wire.

If I run owfs manually as follows:-

owfs -c /etc/owfs.conf --usb=ALL

then absolutely nothing happens.  The /etc/owfs.conf file is:-

 SOURCES 
#
# With this setup, any client (but owserver) uses owserver on the
# local machine...
server: server = localhost:4304
#
# ...and owserver uses the real hardware, by default fake devices
# This part must be changed on real installation
# server: FAKE = DS18S20,DS2405
#
# USB device: DS9490
server: usb = all
#
# Serial port: DS9097
#server: device = /dev/ttyS1
#
# owserver tcp address
#server: server = 192.168.10.1:3131
#
# random simulated device
#server: FAKE = DS18S20,DS2405
#
# OWFS ##
#
#mountpoint = /mnt/1wire
#allow_other
#
### OWHTTPD #

http: port = 2121

### OWFTPD ##

ftp: port = 2120

### OWSERVER 

server: port = localhost:4304


If I run owserver do I need owfs as well?  As I said I'm very confused
and can't see why it used to work but doesn't work any more.  I
*might* have kicked something off manually before that I need to
automate now.

In /etc/init.d there are startup scripts for owftpd, owhttpd and
owserver.  There's nowhere that's running owfs at startup, but as
noted above running it manually doesn't seem to help at all.

Re: [Owfs-developers] Everything is (apparently) running but nothing at /mnt/1-wire

2014-05-06 Thread Eloy Paris
The owfs binary should also be run with a mount point of /mnt/1-wire so 1-wire 
devices can show up at that directory. It doesn't seem like owfs is running.

Cheers,

Eloy Paris.-

more than one server is opening the usb port
you should run the owserver, and others servers should connect to it
