NAME¶

firehol-tos - set the Type of Service (TOS) of packets

SYNOPSIS¶

tos value chain [rule-params]

DESCRIPTION¶

The tos helper command sets the Type of Service (TOS) field in packet headers.

The value can be an integer number (decimal or hexadecimal) or one of the descriptive values accepted by iptables(8) (run iptables -j TOS --help for a list).

The chain will be used to find traffic to mark. It can be any of the iptables(8) built in chains belonging to the mangle table. The chain names are: INPUT, FORWARD, OUTPUT, PREROUTING and POSTROUTING. These names are case-sensitive.

The rule-params define a set of rule parameters to match the traffic that is to be marked within the chosen chain. See firehol-params(5) for more details.

Any tos commands will affect all traffic matched. They must be declared before the first router or interface.

EXAMPLES¶

 # set TOS to 16, packets sent by the local machine


 tos 16 OUTPUT


 # set TOS to 0x10 (16), packets routed by the local machine


 tos 0x10 FORWARD


 # set TOS to Maximize-Throughput (8), packets routed by the local


 #              machine, destined for port TCP/25 of 198.51.100.1


 tos Maximize-Throughput FORWARD proto tcp dport 25 dst 198.51.100.1
