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, ex‐
         cept for short bursts of 2 packets per second

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