NAME
destctrls - per-destination controls for HylaFAX servers
DESCRIPTION
The HylaFAX configuration parameter DestControls specifies whether or
not to apply per-destination controls on job characteristics such as
the time-of-day to place a call.
The controls file is a simple ASCII file containing a series of records
of the form:
dest param = value ... param = value
where dest is a regular expression matched against the canonical form
of a destination phone number and parameters are specified by named
assignments (though the ‘‘=’’ can also be left out). Whitespace may be
used freely though it is used to identify the end of dest and the start
of the parameter list. Parameter values are parsed exactly as
specified in hylafax-config(5); i.e. values with embedded whitespace
may be enclosed in quote marks (‘‘"’’).
Comments are introduced with a ‘‘#’’ character and extend to the end of
the line. Parameter lists may be continued across lines by starting
subsequent lines with a whitespace character (lines commented out with
‘‘#’’ are also considered to be part of a continued record).
The order of entries in a file is important. When a parameter value is
needed faxq sequentially scans the file until it finds a record that
matches the canonical form of the destination phone number. If the
requested parameter is defined in this record, then the value is
returned, otherwise a default value is used from the faxq configuration
file.
The following parameters may be specified on a per-destination basis;
consult hylafax-config(5) for a description of each parameter (except
RejectNotice which is described below).
Tag Type Default Description
MaxConcurrentCalls integer 1 max concurrent jobs to process for a destination
MaxDials integer unlimited max phone calls to make to transmit a job
MaxSendPages integer unlimited max pages to permit in a send
MaxTries integer 3 max attempts to transmit a job
Modem string Any ModemGroup to use for destination
RejectNotice string - rejection notice for transmit job
TimeOfDay string Any default time-of-day restrictions
VRes integer - Vertical resolution
UseXVRes integer - Usage of extended resolutions
The Modem parameter controls which ModemGroup is used in sending faxes
to the destination. If the user assigns a ModemGroup for a specific
job where all modems are outside of this ModemGroup matching a
destination, then the value of Modem is overridden by the user’s
assignment. Likewise, if the user assigns a ModemGroup for a specific
job where some, but not all, of the modems are included in this
ModemGroup matching a destination, then the value of Modem is
overridden by the inclusive set of modems found in both.
The RejectNotice parameter controls whether or not to reject jobs to
the destination. Jobs that are rejected are done so without placing a
phone call and the associated message is returned to the job submitter.
This facility can be used to disallow calling sensitive phone numbers;
for example
.*911$ RejectNotice = "Calls to emergency numbers are not permitted"
The VRes parameter controls the vertical resolution. Possible values
are 98 (normal resolution, equivalent to sendfax -l option) and 196
(fine resolution, equivalent toi sendfax -m option).
The UseXVRes parameter is used to enable or disable the usage of
extended resolutions supported by the receiver. Possible values are 1
(enable extended resolutions usage, equivalent to sendfax -G option)
and 0 (disable extended resolutions usage). This parameter supercedes
the usage of VRes.
In addition to the above parameters, any other parameters that are
specified are automatically accumulated and passed to programs invoked
by faxq, such as faxsend and pagesend. This is a convenient mechanism
for defining configuration parameters for all modems without having to
modify each modem-specific configuration file. For example,
.* SessionTracing = 0x4f
This mechanism also makes it easy to control transmit-related
parameters according to the destination phone number. For example, to
disable use of ECM and restrict the transmit speed when placing
international phone calls one might use:
[+][^1] DesiredBR=3 DesiredEC=0
NOTES
Beware that canonical phone numbers have a leading ‘‘+’’ which is a
special character for regular expressions. An easy way to match ‘‘+’’
is with ‘‘[+]’’; e.g. ‘‘[+]14159657824’’.
