tc
is for “traffic control”
humanoid traffic light, its hand held up as though directing traffic: packets! stop/slow down/go the other way!
great for simulating network problems!
make your internet slow
$ sudo tc qdisc add dev
wlp3s0 root netem
delay 500ms
(delay packets by 500ms)
and fast again:
$ sudo tc qdisc del dev
wlp3s0 root netem
netem rules
netem (“network emulator”) is a part of tc that lets you:
- drop
- duplicate
- delay
- corrupt
packets. see the man page $ man netem
make your brother’s internet slow
Have a Linux router? You can configure tc on it to make your brother’s internet slower than yours. google “tc QoS” for a start.
show current tc settings
$ tc qdisc show
$ tc class show dev DEV
$ tc filter show dev DEV

smiling stick figure: tc can do 10 million more things! This is just the beginning!
