[SOLVED]hddtemp without sudo

sHyLoCk · 2009-06-27 17:36:08

Hello!
Is there anyway of getting hddtemp to work without having to key in the password? I have tried adding

shylock ALL = NOPASSWD: /usr/sbin/hddtemp

Also tried:

%hwmon ALL = NOPASSWD: /usr/sbin/hddtemp

What I'm trying to do is making an alias like I did with gpu temp

alias gpu?='nvclock -i | grep temp'

For Hddtemp as well. Now my only option left is to echo my password and feed it to sudo, which is not a good idea I think. Any help?

%<group> ALL = NOPASSWD: /usr/sbin/hddtemp

or you can do

<yourusername> ALL = NOPASSWD: /usr/sbin/hddtemp

but than you need to run hddtemp with sudo infront of it
I don't think it's smart to give a normal user access to /dev/sda

Edit: remember to use visudo!

Eww, this looks ugly.

Another approach is to add hddtemp to your daemons array in /etc/rc.conf and modify /etc/conf.d/hddtemp. Mine looks like:

PARAMS="-q -l 127.0.0.1"
DRIVES="/dev/sda"

Start the daemon as root "/etc/rc.d/hddtemp start", and as normal user run "nc localhost 7634"

Thnx 4ur reply.Hmm I already said I tried that, still asking for password. Temporarily I'm using echo to solve this issue, which is a horrible solution! I need a better one.

Yes I did that already. Still says Permission denied without sudo.

You won't need to start the daemon manually if you put it in the daemons array.

something worth noting, you have to log in/out again for groups and sudoers changes to take affect. the nc method is better and "works for me" but the visudo method shouldn't ask for a password once you log in/out, if you've typed the line correctly.

As root

chown +s /usr/sbin/hddtemp

Then as user

hddtemp

and it will work :-) No crappy sudo required. The "downside" is, that with this version EVERY user on your computer can run the command hddtemp and will get a result. You have the choice

Adding the suid bit to an executable is always kindof risky though..

I don't think the problem is with /usr/sbin/hddtemp
I'm getting: /dev/sda: open: Permission denied
So, /dev/sda is the problem which is denying access to hddtemp in normal user mode.

arkham · 2009-06-28 01:12:45

Follow these steps:

1) Run as root

nano /etc/conf.d/hddtemp

PARAMS="-q -l 127.0.0.1"
DRIVES="/dev/sda"

2) Run as root

/etc/rc.d/hddtemp start

3) Run as root

nano /etc/rc.conf

Add hddtemp to the daemons array

4) Run as normal user

nc localhost 7634

Hmm why is it not letting me

:: Starting HDDTemp                                                      [FAIL]

I've added to daemons array and rebooted?

arkham · 2009-06-28 01:33:11

Mmm, are you sure the hard disk is /dev/sda? What is the output of

mount

sHyLoCk · 2009-06-28 01:43:22

Thanks for all your replies. Ok I managed to start it ith another reboot after reinstalling netcat.
nc localhost 7634 shows me :

|/dev/sda|???|ERR|*

Yes it's /dev/sda, I'm getting temperature by using sudo hddtemp /dev/sda
When I try without sudo it says /dev/sda open: Permission Denied.
Here's mount output:

$ mount
/dev/sda5 on / type ext4 (rw)
none on /dev type ramfs (rw,relatime)
none on /proc type proc (rw,relatime)
none on /sys type sysfs (rw,relatime)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw)
/dev/sda1 on /windows type fuseblk (rw,allow_other,blksize=4096)
/dev/sda6 on /home type ext4 (rw)
gvfs-fuse-daemon on /home/shylock/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=shylock)
/dev/sdb3 on /media/Videos type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
/dev/sdb5 on /media/Misc type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
/dev/sdb4 on /media/zer0 type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
/dev/sdb1 on /media/Music type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)

EDIT: Ok I dont know what happened now i cant even use sudo?
$ sudo hddtemp /dev/sda

/dev/sda: Permission denied

Mmm I just realized I made a mistake; /etc/conf.d/hddtemp should contain

PARAMS="-q -l 127.0.0.1"
DRIVES="/dev/sda"

I forgot the closing double quote in my original posts (now edited )

Restart hddtemp as root

/etc/rc.d/hddtemp restart

Run as user

nc localhost 7634

Hopefully, it should work now; with this solution, you will never have to use the hddtemp command, just run netcat everytime you want to know the temperature.

Thanks arkham, but my PARAMS field was ok, the problem was that I had "chown" hddtemp to my username and it wasn't letting me access /dev/sda. i changed its ownership back to root and now I can use the command you suggested:
nc localhost 7634
to get the temp.
