NAME

logindevperm, fbtab- login-based device permissions

SYNOPSIS

/etc/logindevperm

DESCRIPTION

The /etc/logindevperm file contains information that is used by login(1) and ttymon(1M) to change the owner, group, and permissions of devices upon logging into or out of a console device. By default, this file contains lines for the keyboard, mouse, audio, and frame buffer devices.

In the Trusted Solaris environment, logindevperm entries are not needed for the keyboard, mouse, and frame buffer devices, because sensitivity labels on these devices prevent access by user processes. Device allocation based on allocate(1M) is the preferred method of setting device ownership and permissions on other devices, such as audio.

The owner of the devices listed in /etc/logindevperm is set to the owner of the console by login(1) . The group of the devices is set to the owner's group specified in /etc/passwd . The permissions are set as specified in /etc/logindevperm .

Fields are separated by TAB and/or SPACE characters. Blank lines and comments can appear anywhere in the file; comments start with a hashmark, ` # ', and continue to the end of the line.

The first field specifies the name of a console device (for example, /dev/console ). The second field specifies the permissions to which the devices in the device_list field (third field) will be set. A device_list s a colon-separated list of device names. A device entry that is a directory name and ends with "/*" specifies all entries in the directory (except "." and ".."). For example, "/dev/fbs/*" specifies all frame buffer devices.

Once the devices are owned by the user, their permissions and ownership can be changed using chmod(1) and chown(1) , as with any other user-owned file.

Upon logout the owner and group of these devices will be reset by ttymon(1M) to owner root and root's group as specified in /etc/passwd (typically other ). The permissions are set as specified in the /etc/logindevperm file.

FILES

SUMMARY OF TRUSTED SOLARIS CHANGES

The use of logindevperm is not supported, and the default /etc/logindevperm file has all entries commented out.
