NAME

firehol-tosfix - apply suggested TOS values to packets

SYNOPSIS

tosfix

DESCRIPTION

The tosfix helper command sets the Type of Service (TOS) field in packet headers based on the suggestions given by Erik Hensema in iptables and tc shaping tricks (http://www.docum.org/docum.org/faq/cache/49.html).

The following TOS values are set:

•   All TCP ACK packets with length less than 128 bytes are assigned Minimize-Delay, while bigger ones are assigned Maximize-Throughput

•   All packets with TOS Minimize-Delay, that are bigger than 512 bytes are set to Maximize-Throughput, except for short bursts of 2 packets per second

The tosfix command must be used before the first router or interface.
