Hi,
I am trying to use the following script to limit my passive ftp traffic
to 35KBytes.
Problem is, it kill''s the entire connection on that computer. The
script is running on the same machine as the ftp server. I was hoping
to limit the ftp traffic, and only the ftp traffic, leaving the computer.
It seems to limit everything, i tried transfering a file with samba and
the whole computer came to a screeching halt.
Any words of wisdom?
#!/bin/bash
#shaping passive ftp traffic
# mark the outbound passive ftp packets on ports 50000-51000
iptables -t mangle -D POSTROUTING -o eth0 -j MYSHAPER-OUT 2> /dev/null >
/dev/null
iptables -t mangle -F MYSHAPER-OUT 2> /dev/null > /dev/null
iptables -t mangle -X MYSHAPER-OUT 2> /dev/null > /dev/null
iptables -t mangle -N MYSHAPER-OUT
iptables -t mangle -I POSTROUTING -o eth0 -j MYSHAPER-OUT
iptables -t mangle -A MYSHAPER-OUT -p tcp --dport 50000:51000 -j MARK
--set-mark 1
# shape the traffic to 35Kbytes
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 35kbps
tc filter add dev eth0 parent 1: prio 0 protocol ip handle 1 fw flowid 1:1
