        NAME

        fireqos - an easy to use but powerful traffic shaping tool

        SYNOPSIS

        fireqos CONFIGFILE [start | debug] [ -- conf-arg ... ]

        fireqos { stop | clear_all_qos }

        fireqos status [name [ dump [class]]]

        fireqos { dump | tcpdump } name class [ tcpdump-arg ... ]

        fireqos { drops | overlimits | requeues } name

        DESCRIPTION

        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.

        COMMANDS

        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).

        clear_all_qos

        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, etc.)

        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.

        Note

        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.

        overlimits

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

        requeues

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

        FILES

        /etc/firehol/fireqos.conf
