logindevperm



DESCRIPTION

       /etc/logindevperm  is  an  ASCII  file  which contains the
       rules for pam_devperm.

       There is one entry per line. Comments start with a  #  and
       extend  to  the end of the line. Blank lines or lines with
       only a comment are ignored. All  other  lines  consist  of
       three fields delimited by whitespace:

       login device
              If a user signs onto the system on this device, the
              rule will be evaluated.

       octal permission number
              The octal permission number  to  which  the  access
              rights of devices should be changed.

       list of devices
              A  ":"-delimited  list  of devices, which should be
              owned by the user who signs onto the sytem.

       All device names are absolute paths. A path that  ends  in
       "/*"  refers to all directory entries except "." and "..".
       The login device could be also the xdm display  (like  :0)
       or a "*" matching all devices.

       If  the  tty  the  user  does login matches a login device
       name, the permissions of the devices in the  ":"-delimited
       list  are  set as specified in the second field, and their
       ownership is changed to that of the uid of the user.

       All rules are tried one by one. Every match is  evaluated.


EXAMPLE

       # Give access to the CD-ROM and floppy devices.
       # users in the correct group should be also able
       # to write to the floppy. user needs to login with xdm/kdm
       :0 0600 /dev/cdrom:/dev/cdrom1:/dev/cdrom2
       :0 0660 /dev/fd0:/dev/fd1
