       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

       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

        - 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)
