fireqos - an easy to use but powerful traffic shaping tool
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
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.
debug
, FireQOS also prints all of the tc(8) commands it executes.
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.
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 totcpdump
in parallel, your dumps would be wrong. So it locks itself to prevent such a case.
