Simple action in tc(8) Linux Simple action in tc(8)NAME
simple - basic example action
SYNOPSIS
tc ... action simple [ sdata STRING ] [ index INDEX ] [ CONTROL ]
CONTROL := { reclassify | pipe | drop | continue | ok }
DESCRIPTION
This is a pedagogical example rather than an actually useful action. Upon every access, it prints the given STRING which may be of arbi-
trary length.
OPTIONS
sdata STRING
The actual string to print.
index INDEX
Optional action index value.
CONTROL
Indicate how tc should proceed after executing the action. For a description of the possible CONTROL values, see tc-actions(8).
EXAMPLES
The following example makes the kernel yell "Incoming ICMP!" every time it sees an incoming ICMP on eth0. Steps are:
1) Add an ingress qdisc point to eth0
2) Start a chain on ingress of eth0 that first matches ICMP then invokes the simple action to shout.
3) display stats and show that no packet has been seen by the action
4) Send one ping packet to google (expect to receive a response back)
5) grep the logs to see the logged message
6) display stats again and observe increment by 1
