faxwatch - monitor low-level HylaFAX server actions
/usr/sbin/faxwatch [ -g ] [ -l ] [ -h host ] trigger-expression
faxwatch registers interest in one or more events on a HylaFAX server
and then prints subsequent event messages to the standard output. The
faxwatch program is intended mainly for testing the event distribution
mechanism used by the HylaFAX servers.
The trigger-expression is supplied as an argument to a ``SITE TRIGGER''
command passed to the hfaxd(8C) The syntax for this expression is:
where <class> defines a class of events and is one of:
J for job-related events,
S for fax send-related events,
R for fax receive-related events, and
M for modem-related events.
A <mask> is a 4-hex-digit mask of trigger events (see the table below).
If ``*'' is specified then all events in the class are matched.
An <id> can be used to restrict matches to a specific job or modem.
Eventually this will need to be generalized for job groups.
Thus an example specification that would catch any event for the modem
on ttyf2 would be ``M<ttyf2>*'', and to be notified when job 1932 is
requeued or completes one would use ``J<1932>4c60''.
The output from faxwatch is ASCII text that describes each event.
faxwatch runs until it is interrupted.
-g Display times and dates in Greenwich Mean Time (GMT). NB:
this is the default.
-h host Report the status of the server on a specific host. The host
may be either a symbolic name or a network address. IPv6
addresses are given in ``[xx:xx::x]:port'' format. If no -h
option is supplied, faxwatch uses the FAXSERVER environment
variable to identify the HylaFAX server to contact. If this
variable is not set, then faxwatch checks for a setting in
the configuration files (first in the per-user file and then
in the system-wide file). If all of the above fails, then
faxwatch attempts to contact a server on the machine where it
-l Display times and dates in the local timezone of the server.
-v Trace the protocol exchanges between faxwatch and the hfaxd
processes on the standard output.
The following table specifies the current set of events that may be
monitored. This information is subject to change; consult the source
code for reference.
