    Incidentally, a really good source of specific info about Linux problems is the site askubuntu.com. It's one of the Stackexchange Q&A sites, and full of very clued up folks. Obviously a lot of info is going to be applicable to non-Ubuntu machines, too.

    Posted By: wookeyEd, Why would you install it if you didn't want it running/working?


    Oh, yes, forgot to answer that.

    Perhaps because:

    • You only want to use the command line tools (to access a server on another machine).

    • You only want the owserver, not the others.

    • You want to run them non-privileged.

    • You don't want them to access all your 1-wire buses.


    In general, I think there are enough options with the way you use ow that I don't think “they can be sensibly run with defaults”.

    If you only want to use the command-line tools then just install ow-shell.

    If you only want the owserver then just install owserver, which if installed, runs, unless configured not to.

    Use owfs.conf to configure which buses are accessed.

    The packaging allows all this and seems entirely sensible to me.

    An /etc/default/owserver on/off switch would be useful. As ever patches are welcome.

    Anybody considered rolling this up into a PPA to smooth out the learning curve a little? I would, except for the slight handicap of not knowing the first thing about packaging. Quite happy to try and flag down a MOTU or chase the maintainers about it though. Rolling your own from source is a bit unnecessary these days.

    As an experiment I recently bought a USB dongle for 1-wire devices. Instead of going for the mainstream device, I chose a cheaper one from an online auction site and shipped from Hong Kong, which also had the advantage of connecting using 3.5mm jacks making it easier to connect devices.

    It works fine on my Windows machine, but my Linux box doesn't have the driver for the USB to serial bridge used (which appears to be a Chinese knock-off of another Chinese device) and it's not readily available (short of configuring and compiling it into my kernel). Newer versions of the kernel should have support built-in, but my distribution tends to lag everyone else for stability and hasn't been updated for a while (a new one is in beta testing).

    Now, I wish I'd bought the mainstream device instead, but I'll do some basic testing on Windows and migrate to Linux when my distribution is updated.

    Be warned.

    Seret - it's already in a PPA. I posted the details earlier in this thread.

    And it's working it's way through the distro release process already - no need to pester maintainers.

    Ah, so you did. I saw post of folks farting about compiling and searched the thread for "launchpad", but you've only got your very own repo. Nice work! ;)
