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:


everything went fine


invalid JOB ID specified on the command line


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


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


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