       FireQOS is a program that helps you configure traffic shaping on Linux.

       Run without any arguments, fireqos will present some help on usage.

       When    given    CONFIGFILE,    fireqos    will    use   the   named   file   instead   of
       /etc/firehol/fireqos.conf as its configuration.

       The parameter name always refers to an interface name from the  configuration  file.   The
       parameter class always refers to a named class within a named interface.

       It is possible to pass arguments for use by the configuration file separating any conf-arg
       values from the rest of the arguments with  --.   The  arguments  are  accessible  in  the
       configuration using standard bash(1) syntax e.g. $1, $2, etc.


       start; debug
              Activates  traffic  shaping  on all interfaces, as given in the configuration file.
              When invoked as debug, FireQOS also prints all of the tc(8) commands it executes.

       stop   Removes all traffic shaping applied by FireQOS (it does  not  touch  QoS  on  other
              interfaces and IFBs used by other tools).

              Removes  all  traffic shaping on all network interfaces and removes all IFB devices
              from the system, even those applied by other tools.

       status Shows live utilisation for the specified interface.  FireQOS will show you the rate
              of traffic on all classes, adding one line per second (similarly to vmstat, iostat,

              If dump is specified, it tcpdumps the traffic in the given class of the interface.

       tcpdump; dump
              FireQOS temporarily mirrors the traffic of any leaf class to an IFB  device.   Then
              it runs tcpdump(8) on this interface to dump the traffic to your console.

              You  may  add  any tcpdump(8) parameters you like to the command line, (to dump the
              traffic to a file, match a subset of the traffic, etc.), for example this:

                     fireqos tcpdump adsl-in voip -n

              will start a tcpdump of all traffic on  interface  adsl-in,  in  class  voip.   The
              parameter -n is a tcpdump(8) parameter.


                     When  FireQOS is running in tcpdump mode, it locks itself and will refuse to
                     run in parallel with another FireQOS altering the QoS, or  tcpdumping  other
                     traffic.   This  is because FireQOS reserves device ifb0 for monitoring.  If
                     two FireQOS processes were allowed to tcpdump in parallel, your dumps  would
                     be wrong.  So it locks itself to prevent such a case.

       drops  Shows packets dropped per second, per class, for the specified interface.

              Shows packets delayed per second, per class, for the specified interface.

              Shows packets requeued per second, per class, for the specified interface.
