Ksensors versus hddtemp in "normal user". Why can't I see hddtemps

hello pals. I'm trying, without succesfull, see my hddtemps on ksensors.
I've read this
http://bbs.archlinux.org/viewtopic.php?id=75639

but... I can't see how do the SUID solve, or, in another way, how can I solve my issue once when I try access my hddtemps on normal user, I've a "permission denied"

Could you help me?

=================
or... ksensors reads hddtemps like root (kdesu ksensors)

how could I start it like root via daemon on /etc/rc.conf?

If you're really sure that you'd never do accidents like dd'ing directly to your drive or stuff like that, you could simply add your user to the 'disk' group.

edit: oops, that won't help with SMART issues like temperature reading, sorry

^^ i actually didn't undertsand your problem here.

since i'm not a kde user, Ksensors check the hddtemp daemon or it executes hddtemp directly???

if it uses hddtemp daemon then u can use netcat as normal user to connect to hddtemp daemon but if Ksensors uses hddtemp directly as command  then you need to set uid to hddtemp binary (that may cause problems in future).

neways tell me if i understood the problem correctly??

hddtemp runs the deamon as root.
there are only 2 ways to get a user to access it.

- use suid (highly insecure)
- use netcat

Is there a way to use netcat read hddtemp's output for /dev/sdb?
Trying to do it in my .conkyrc setup, and in my box hdd2 is the hotter one.
I'm trying to learn something about netcat, it seems to be a whole bag of tricks.
I don't even begin to understand how "nc localhost 7634" manages to read the temp, even after reading man pages for hddtemp and nc.
