SYNOPSIS

       gradm  [  -E  ]  [  -R  ]  [  -C  ]  [ -F ] [ -L <logfile> ] [ -O <filename|stream> ] [ -M
       <filename|uid> ] [ -D ] [ -P [rolename] ] [ -a  <rolename>  ]  [  -n  <rolename>  ]  [  -p

DESCRIPTION

       gradm is the userspace RBAC parsing and authentication program for grsecurity

       grsecurity  aims  to  be a complete security system for Linux 2.4.  gradm performs several
       tasks for the RBAC system including authenticated via a password to the kernel and parsing
       rules to be passed to the kernel.

OPTIONS

       All options to gradm are mutually exclusive, except for -L and -O.

       -E     Enable the RBAC system

       -R     Reload the RBAC system (only valid while in admin mode)

       -C     Perform  a  check  of the RBAC policy, running the same analysis against it that is
              performed when enabling.

       -F     Toggle full learning mode.  If used only with -L, it enables  the  RBAC  system  in
              full  learning  mode.  If used with -L and -O, it parses the full learning logs and
              generates a complete ruleset.

       -M <filename|uid>
              Remove an execution ban on a given uid or filename that has been put  in  place  by
              the RES_CRASH resource restriction of the RBAC system.

       -L <logfile>
              Parses  the learning logs.  Accepts an argument which specifies the logfile to scan
              for the learning logs.  If "-" is specified as the logfile, stdin will be  used  as
              the learning log.  This option can be used with -E, -O, or -F.

       -O <filename|stream>
              Specifies  output mode.  Requires a single argument that can be "stdout", "stderr",
              or a regular file.  Only used with -L or -F.

       -D     Disable the RBAC system

       -P [rolename]
              Without an argument, it sets the password for administering the RBAC system.   With
              a role name as an argument, it sets the password for that given special role.

       -a <rolename>
              Authenticate to a special role that requires a password.

       -n <rolename>
              Authenticate to a special role that does not require a password.

       -p <rolename>
              Authenticate through PAM to a special role.

       -u     Removes  yourself from your current special role, reverting back to the normal role
              selection.  To be used, for instance, for logging out  of  an  admin  role  without
              exiting your shell.

       -V     Displays  verbose  policy  statistics when enabling the RBAC system or checking the
              RBAC policy.  Can only be used with -C, -E, or -F -L <filename>

       -h     Display help information

       -v     Print version information and exit
