       faxq-helper - privileged helper process to access the fax queue


       faxq-helper <command> [<options>]


       faxq-helper is part of the internal workings of faxspool(1).

       Formerly,  the  /var/spool/fax/outgoing directory was world-writeable, leading to all sort
       of funny symlink attacks against faxspool(1) and faxrunq(8).

       These days, it's owned by the user ``uucp'', and only this user can write to  it.   To  be
       able to put jobs there, faxspool(1) calls faxq-helper for very clearly defined purposes:

        - make a new queue directory

        - put a new fax G3 file into this queue directory

        - put a JOB file into this queue directory, and activate the fax job

       and possibly:

        - remove a fax job from the queue (to be used by faxrm and in case of errors)

        - re-queue a job that has been suspended due to repeated failures (faxq -r)

       To  achieve  this, faxq-helper is installed set-user-id uucp.  If you remove the suid bit,
       or chown the fax queue directory to a different user, it will stop working.


       faxq-helper has the following exit() values:

       0      everything went fine

       1      invalid JOB ID specified on the command line

       2      some  problem   with   the   directory   setup   of   the   outgoing   queue   dir,
              /var/spool/fax/outgoing (it will print a detailed error message)

       3      some problems with the user ID setup of the ``uucp'' user (it will print a detailed
              error message)

       10     failure to process the specified command (it will print a detailed error message)
