    Using something like:

    function get_temp() {
    	$temp_out = "";
    	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
    	$temp_out = (trim($dfout[0]).'°');
    
    	return $temp_out;
    }
    

    Would be better except that the above code only correctly returns ° when it it called from the system widget php code. When it's called from the javascript update function it just shows °.  :-\

      Needs a semicolon after that, it's "°"

        @stephenw10:

        I would think it would be better to have the get_temp function return a value including the ° symbol.
        E.g. 45.2°
        That way only one file has to be altered.

        @jimp:

        You should really use °, don't hardcode such a symbol directly in html/js

        I agree. I was surprised it worked actually. I probably depends on what your viewing it on.

        Steve

        Steve and jimp,
        Sorry for been slow, but what you say is I should not really add the ° symbol to the ajax.js file? But could I add the ASCII code there or better not at all? As I mentioned I am not a good programmer :(

            It's bad form (invalid html/js/etc) to put in a symbol instead of the html entity. It may work, but it's not guaranteed to do so.

              Nope.   ???
              Same as before, using:

              
              unction get_temp() {
              	$temp_out = "";
              	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
              	$temp_out = (trim($dfout[0]).'°');
              
              	return $temp_out;
              }
              
              

              Results in initially correct ° then 46.5°C
              Hmm.

                It may be getting run through htmlentities somewhere in there then. Might be safe to leave the symbol in there if that is the case.

                  Unfortunately using:

                  
                  function get_temp() {
                  	$temp_out = "";
                  	exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
                  	$temp_out = (trim($dfout[0]).'°');
                  
                  	return $temp_out;
                  }
                  
                  

                  Results in the attached image.

                  Perhaps the character set is being restricted somewhere?

                    That's a unicode degree symbol, try a standard ascii one, º

                        No different. I entered both º and ° and both result in ��.  :-\

                          I'd just leave it out.

                          (Or convert to Kelvin, no symbol there! ;-)

                            Kelvin nice!  :D

                            I'll stick with the nasty ° addition to ajax.js. I'm clueless about js, how would one enter that as an ascii code instead? Using ° is not working.

                              Kelvin - LoL can core temp convert the output?

                                This is awesome. My i3-540 reads 29C, 29C, 36C, 36C lol.

                                Will this be included in future snapshots? Or should we go ahead and modify it ourselves?

                                  That is cool, which type of case/box you use? I get 54C with an Atom D510 that sits in a Jetway Motherboard that is in a passive cooled M-350 box.

                                    Though this is 2.0 RC feedback section, but since the topic is on coretemp, I wanted to see if there is a pfsense 1.2.3 compatible 32-bit coretemp file out there that I can use. Moved to 1.2.3 last night as 64-bit snapshot snort is broken since weeks and I don't have the patience to wait any longer.

                                      Pull the file from a FreeBSD 7.2 install CD.

                                          you don't have to be a FreeBSD user to copy a file off the install CD.

                                          download a copy of 7.1 Install ISO.. Mount the ISO with your favorite Virtual CD program, like MagicISO… Then copy the files from cddrive/boot/kernel
