I can send you mine, it’s a modified version of one I found
somewhere on the net to be able to limit bandwith on a linux router. I did no
cleaning up or anything #!/bin/bash # 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 # # # Name of the traffic control command. TC=/sbin/tc IPTABLES=/sbin/iptables # The network interface we're planning on limiting bandwidth. IF1=eth1.106
# Interface IF2=eth0
# Interface # Download limit (in mega bits) DNLD=100mbit
# DOWNLOAD Limit # Upload limit (in mega bits) UPLD=100mbit
# UPLOAD Limit # IP address of the machine we are controlling #IP=81.18.0.0/24
#Host IP #IP=0.0.0.0/0
#Host IP # Filter options for limiting the intended interface. IN="$TC filter add dev $IF2 protocol ip parent 1:0 prio

MARK --set-mark 106 # INBOUND matches on fwmark 106 and gets shaped when it leaves
the IF2 interface $TC qdisc add dev $IF2 root handle 1: htb
