如果有 root 權限, 又不介意同時限制 DL&UP, 那可以直接用 tc 指令

詳見: tc

apt-get install iproute2

# rate 30mbit        # Sets the maximum average download rate to 30 mbps
# burst 1mb          # Amount of bytes that can be burst at ceil speed

tc qdisc add dev eth0 root tbf rate 30mbit burst 5mb latency 500ms

# checking

tc qdisc show dev eth0

qdisc tbf 8008: root refcnt 13 rate 30Mbit burst 5Mb lat 500ms

# 取消限速

tc qdisc del dev eth0 root
