Re: [Owfs-developers] OWFS on PogoPlug Pro

I just got owfs 2.8p12 and temploggerd working on a Dockstar yesterday, and I would think that PogoPlug Pro would be very similar. Here is my recipe for getting it working on a Dockstar with Arch Linux. I haven't run through this a second time yet to figure out where I wrote down the details incorrectly or omitted a step, but will do so in the next couple days because I have another Dockstar to convert. 1. Put Arch Linux on the machine. There are various guides for that, but yesterday a fellow wrote a blog entry about installing another system on a Pogoplug Pro, and the first 60% of the entry is really just about how to put Arch Linux on the machine. By the way, I can recommend crashplan as a backup system. http://www.opticality.com/blog/2011/07/16/installing-crashplan-on-a-pogoplug-pro/ 2. Install python2, swig, fuse, rrdtool and ttf-dejavu. The last of these is fonts that temploggerd needs. There is owfs in the Arch linux packages as an unsupported, user-submitted package, but it is 2.8p8, and I decided to try the latest. 2. Download owfs and temploggerd from sourceforge. You have to make 2 simple changes to the configure script for owfs because the default python for Arch Linux in python 3. The configure script looks for python up through 2.5, but Arch Linux installs 2.7, so you need to update the script to check for that. Find the line for ac_prog in python-config python2.5-config python2.4-config python2.3-config and make it into for ac_prog in python-config python2-config python2.5-config python2.4-config python2.3-config And then find the line for ac_prog in python python2.5 python2.4 python2.3 python2.2 python2.1 python2.0 python1.6 python1.5 python1.4 python and make it into for ac_prog in python python2 python2.5 python2.4 python2.3 python2.2 python2.1 python2.0 python1.6 python1.5 python1.4 python This change, or looking for python2.7, ought to be incorporated into the main build. Looking in the owfs package, I see that an alternative to changing the configuration script is to run ./configure --with-python="/usr/bin/python2" --with-pythonconfig="/usr/bin/python2-config" 3. Do the usual ./configure, make, sudo make install on both owfs and temploggerd. owfs ends up in /opt/owfs. Temploggerd gets spread around bit, but we'll get to that in a moment. First, check that owfs works. I put a DS9490R into the dockstar, and attached an iButtonLink sensor that I had handy. I ran /opt/owfs/bin/owserver -u by hand, then ran /opt/owfs/bin/owdir and found that it listed both the USB interface and the temperature sensor. Running owread /<id>/temperature gave me the temperature and verified that it was working properly. To get it to run when it boots, I think I need to put the command into /etc/rc.local, but I haven't done that yet. With the owserver working, I turned my attention to temploggerd. First, I needed a web server, so I picked lighttpd and installed that. The only change I made to lighttpd.conf was to add server.modules +=("mod_cgi") cgi.assign = ( ".cgi" => "" ) The first line enables cgi, and the second line tells it to run cgi script directly rather than invoke something else to interpret it. Now on to temploggerd. The binary for temploggerd is in /usr/local/bin, the configuration file lands by default in /usr/local/lib/temploggerd, and the image and template directories are in /usr/local/share/temploggerd. I found configuring temploggerd frustrating initially because I wasn't really clear on all the details, but it is one of those "easy once you understand it" tasks. Here is my config file, designed just to show 1 temperature sensor. # This is the default values # Empty owfs_dir means "search in /proc/mounts for fuse mount" owfs_dir "" # if owshell_path is set, the simple owfs shell-commands owdir,owread,owpresent # will be used instead of reading from a mounted fuse-filesystem. owshell_path "/opt/owfs/bin/" owshell_params "-s 4304" rrdfile_path "/srv/http/temploggerd/rrd/" rrdfile "temperature.rrd" all_temperature.cgi.templ sensor_temperature.cgi. templ rrdfile_description "temperature.rrd" "Temperatures" # and for those sensors which didn't specify any rrd-file. rrdfile_default "temperature.rrd" rrdcgi_file "/usr/bin/rrdcgi" www_dir "/srv/http/" base_dir "/temploggerd/" rrdimg_path "rrd/" images_path "images/" cgi_dir "/srv/http/cgi-bin/" cgi_path "/cgi-bin/" tmp_file "/tmp/temploggerd.tmp" images_dir "/usr/local/share/temploggerd/images/" tmpl_dir "/usr/local/share/temploggerd/templates/" tmpl_all_cgi "all.cgi.templ" tmpl_all_default "all_temperature.cgi.templ" tmpl_sensor_default "sensor_temperature.cgi.templ" tmpl_files "index.html" "style.css" "time_links.html" "manual_selection.html" "meta_tags.html" #add_new_sensor_script "add_new_sensor.sh" # Add some own settings rrdfile "temperature.rrd" all_temperature.cgi.templ sensor_temperature.cgi. templ ignore 81.761C26000000 sensor 28.33AF5B010000 "Temperature" temperature temperature.rrd Basically, I set the paths to the proper locations, put in a line to ignore the usb interface, and put in the final line for the temperature sensor. As I said initially, I haven't fully verified that I got all the steps written down properly, and I haven't run through other functions yet to verify that everything works, but going to http://dockstar/temploggerd does let me click though the links and show a graph. This should be enough to get you going, and I will put up a verified recipe later.
