Hi all,<br>
<br>
As promised, here are the final versions of the scripts used to monitor
the temperatures on my mint machine and provide the data via web page.<br>
<br>
The following commands start everything up:<br>
<br>
# section to start temperature monitoring scripts<br>
<br>
cd ~/temperature-scripts<br>
<br>
# commands to start the sensor monitoring script<br>
<br>
mate-terminal --geometry=82x5+0450+800 -t "Monitor Temperature Sensors"
-e "watch -n 15 ./checktemps.sh" &>/dev/null &<br>
<br>
# commands to start the mini temperature web server<br>
<br>
mate-terminal --geometry=82x5+01800+800 -t "Run Temperature Web Server"
-e ./startminitempwebserver.sh &>/dev/null &<br>
<br>
----------------------<br>
<br>
Here is the checktemps.sh which is executed every 15 sec by the watch
command. I made some mods to make this a more standard html file.:<br>
<br>
#!/bin/bash<br>
<br>
# Script to monitor temperatures on the pc and save data to an html
file.<br>
# This script can be called repeatedly using the watch command.<br>
# Ron Frazier - 2013-06-07<br>
<br>
cd ~/temperature-scripts<br>
<br>
{<br>
<br>
# read the temperature sensors and create temporary html file<br>
<br>
echo '<!DOCTYPE html>'<br>
echo '<html>'<br>

<br>

echo ""<br>
<br>
} > ./scratch/scratch-temperature.html<br>
<br>
# copy the temporary file to the usable file to prevent partial file
retrieval<br>
<br>
mv ./scratch/scratch-temperature.html ./temperature.html<br>
<br>
---------------------<br>
<br>
Here is the startminitempwebserver.sh which runs netcat continuously to
serve up my 1 web page. You could do many different pages on different
ports if you wanted. I was never able to get proper formatting on
alternate ports by using the content type definitions. This script
embeds some headers into the web page before it is served. This makes
the browser happy. Not quite sure what all this does, found it on
google, but it works.:<br>
<br>
#!/bin/bash<br>
cd ~/temperature-scripts<br>
<br>
while true; do { echo -ne "HTTP/1.0 200 OK\r\nContent-Length: $(wc -c
<./temperature.html)\r\n\r\n"; cat ./temperature.html; } | nc -l
56789; done<br>
<br>
---------------------<br>
<br>
I had to modify the sudoers file with visudo to allow use of hddtemp
without a sudo password.:<br>
<br>
#<br>
# This file MUST be edited with the 'visudo' command as root.<br>
#<br>
# Please consider adding local content in /etc/sudoers.d/ instead of<br>
# directly modifying this file.<br>
#<br>
# See the man page for details on how to write a sudoers file.<br>
#<br>
Defaults env_reset<br>

Here is a sample of the html file that gets generated every 15
seconds. I can view this from any computer on my network that's
attached to the same router. I could also possibly upload it to
dropbox every 5 minutes, but I don't know if they'd like that.<br>

Thanks for the help in solving my problem. Anyone is welcome to use
the scripts.<br>
<br>

Hip Hip Hurray!

I finally got my remote "weather" monitoring system running. It was
NOT easy. I spent all day (thus far) rewriting and editing scripts
and, among other things, troubleshooting problems with commands that
require sudo and funky web page formatting from netcat. Thanks to all
for the relevant and specific tips you provided. I wouldn't have been
able to do this without your help in any reasonable about of time. I
can now monitor the temperatures inside my downstairs computer from a
web browser on my upstairs computer as long as they're on the same wifi
router. I can even monitor it from my tablet. Very cool!
<br>
<br>
I have implemented a number of the tips you all gave me. Many
different script files are involved, which I hope to post before next
week, so others can benefit from the information. I have also been
working on other technologies, including running spinrite to test a
hard drive in a vm while I'm doing other things with the computer,
which was not possible for me before. I wrote another post about that.
<br>
<br>
You might find this interesting.

This is what I call my master control screen on a second monitor.
That's where I keep track of a number of things I have going on in the
pc.
<br>
<br>
Here's what each window does numbering from left to right:
<br>
<br>
Top Row:
<br>
<br>
window 1: monitors litecoin mining
<br>
window 2: monitors the cpu cores
<br>
window 3: spinrite running in a vm - YEA! (very slowly - BOO!)
<br>
<br>
Middle Row:
<br>
<br>
window 4: litecoin wallet
<br>
window 5: monitors local gpu 1 - mainly temperature
<br>
window 6: monitors local gpu 2 - mainly temperature
<br>
window 7: monitors local weather radar - so I can shut down if storms
are coming
<br>
<br>
Bottom Row:
<br>
<br>
window 8: monitors litecoin pricing
<br>
window 9: monitors temperatures in the basement computer - YEA!
<br>
<br>
Reestablishing all these things when I reboot is a major pain, so I try
not to do so too often.
<br>
<br>
I'm very pleased with the results today, although I had hoped it would
go faster. All the screens auto update. For the ones that are browser
based, I make extensive use of an auto update plugin for firefox and of
the ability to scale the web page in firefox by hitting the ctrl- and
ctrl+ keys. I then size the window to fit the image.
<br>
<br>
Here's the plugin: <a class="moz-txt-link-freetext" href="http://reloadevery.mozdev.org/">http://reloadevery.mozdev.org/</a>
<br>
<br>
There is one bug in my temperature monitoring system. On any
particular refresh of the web page for the Bugs01 machine, it displays
the web page that was active at the time of the previous refresh. I'm
assuming that netcat precaches the file it will be transmitting when it
starts and then waits for a request. I'm not too worried about it
since I have the web page refreshing every 1 minute. On the server
side, it generates a new temperature.html every 15 seconds. So, the
data I'm seeing on the screen could be up to 2 minutes out of date
depending on the timing of the refresh cycle. That's ok for my
purposes.
<br>
<br>
A side effect of having this display is that I can tell if the Bugs01
clock is wandering. I haven't set ntp up on that one yet.
<br>
<br>
Again, thanks for all the help.
<br>
<br>
Sincerely,
<br>
<br>
Ron
