How to control network speed?
Hi,
For some reason, I have a linux machine that has to have a network
bandwidth limitation for the whole system. So I looked into command
tc. And used this script from the internet.
Well, the script returned successful, but in fact it did not effect anything.
Could someone help me? Thanks.

# tc uses the following units when passed as a parameter.
# kbps: Kilobytes per second
# mbps: Megabytes per second
# kbit: Kilobits per second
# mbit: Megabits per second
# bps: Bytes per second
# Amounts of data can be specified in:
# kb or k: Kilobytes
# mb or m: Megabytes
# mbit: Megabits
# kbit: Kilobits
# To get the byte figure from bits, divide the number by 8 bit
