[opensuse-security] udev rules; use of uucp group for devices
Hi, I had asked this question over at the [opensuse] mailing list on 09/14/2008 12:46 AM and got the recommendation to ask the security people about this issue. So here I am. I want to use a USB device which comes up as /dev/ttyUSB0 with the user:group = root:uucp. Now my question is how is the intended use of this device for a normal user? When I look at my user information with the id command I get: uid=1000(linux) gid=100(users) groups=16(dialout),33(video),100(users) I am hesitant to add my user to the uucp group, as I am not sure whether that is the intended use of the group. I know there are some user/groups on Linux only intended for some software and not for real user accounts. I tried to overwrite the udev rule and make the ttyUSB0 device belong to the dialout group, as my user belongs to it, but was not successful with that. Could someone please explain the intended use of the uucp group in connection with hardware devices and how users are intended to access the hardware? Thanks for your help.
