do you know your rights?


I recently got my kodak digital camera working with slackie! SWEET! I still have yet to set it up so that normal users can use it, but with root it is fully functional.

So, with su i was able to xfer the pictures into my users home directory. As expected, the user account was unable to view the pictures, or even get into the directory that was created for the pictures.

As root, i did a chmod -R 666 ./pictures, which should give everyone read/write rights right?

Couldn't get in.

As root, i did a chown -R userx ./pictures, which changed the owner to the user, and should get me in.

Couldn't get in.

So, as su, i loaded up konqueror, went into the properties of the file, changed the group to users, and found another option "allow users to enter directory" or something to that extent. Nobody never told me about that option.

After that, i was able to view my pictures. My question is, what should I have done? ok.. i should've set up my camera correctly before rushing into this, but... what should I do if this situation comes up again?

Thanks,

Murray

I prefer using the rwx way.

chown murray_linux pix
chown <user> <dir>
chmod a+rwx pix
chmod <rights> <dir>

chmod goes like this: r = read w = write x = execute a = all u = user g = group o = other

you could also do chmod o-rwx to remove other user rights but thats your decision.. gl

Also, don't forget that you have to have "execute" permission for a directory before you're allowed to view its contents. So using chmod 666 on a directory will make all the files accessible, but users still won't be able to view the directory listing.

I used to always use the numeric chmod arguments, but also have found that r/w/x are much better, and more flexible, but it's a matter of preference

If your camera is recognised as a USB storage device
it's a piece of cake :) ... on my old 8.1 and with usbmgr
I get it mounted, and r/w-able for users in /camera ...

My fstab entry looks like:
/dev/sda1 /camera msdos umask=000,user,users,rw 0 0

And the config for usbmgr looks like:
Quote:
/usr/local/etc/usbmgr/mount_cam
Code:
#!/bin/bash
/sbin/mount /camera
and
Quote:
/usr/local/etc/usbmgr/usbmgr.conf
Code:
# Photosmart 720 [HP]
vendor 0x3f0 product 0x4002 script mount_cam module scsi_mod, sd_mod, usb-storage
You'd need to check the vendor and product ID's for
you cam, of course :)


Cheers,
Tink

from gphoto's documentation:

"Now that you've got your basic USB system working, you have basically two options to allow user access to USB devices on your Linux system:

allow a certain user and/or group or the whole world access to all USB devices by mounting /proc/bus/usb[1] with adequate user and/or group permissions (default is world-readable and root-only-writable, which is good) "

I don't see an entry in /etc/fstab for that. Should there be? What would it look like if I wanted to give users access to it?

Thanks again!

Murray
