I'm not a programmer but mess about to get things done. I was trying to set
up a low usage php page to show some owfs data and was trying to suss out
the OWNet php stuff. I believe I've come to realize that the Arch Linux ARM
(ALARM) owfs package does not include OWNet php support, and I likely would
need help to figure it out if it did. So I tried to simply display some
file content from the owfs directory and ran into PHP not being able to
read the files (presumably because they were outside the web root). I had a
brainstorm as a result: instead of using /tmp/1wire as the owfs directory,
why not create a directory within the web root, e.g.: /srv/http/1wire?
So now I use an owfs invocation of:
owfs -F -s 4304 --allow_other --readonly /srv/http/1wire
And I have a php page which uses lines like:
$hum = file_get_contents('./1wire/26.0CB401000000/humidity');
echo "<p>Humidity: ", $hum, "%</p>";
This is all being done on a dedicated ARM machine (Seagate DockStar) with
no other critical or sensitive data on it. My router is set to port forward
to this machine from obscure ports for ssh/22 (using key auth.), web
server/80, and owhttp/3001 (--readonly).
Am I opening myself for disaster having this owfs mount directory in the
web root or should this be secure? I'd hate to be opening up my network to
hacking.
Thanks,
Don
