After about a week or more of enjoying a sensible amount of bandwidth on our network (after limiting the rate/ceiling of one particular ip on our network) I noticed that the rules I had been given weren't infallable, something was wrong. For some reason our internal samba traffic (eth1) was also limited to the rate/ceiling of my bandwidth throttling script [see below] It does indeed limit his bandwidth to a max of 60kbps/sec (which is wonderful) but somehow its also limiting our samba traffic to 60kbp/sec also (we only notice it in one direction also (from our server 192.168.0.1 (eth1 interface ip) -> any of our ip's 192.168.0.x). Any idea why it seems to be applying this rule to everyones traffic as it leaves the server on eth1 ? We seem to have full internet download bandwidth (which would be traffic on eth0(about 300k/s) but no internal traffic only passing thru eth1. #!/bin/bash /sbin/tc qdisc del dev eth0 root /sbin/tc qdisc del dev eth1 root /sbin/tc qdisc add dev eth1 root handle 1: htb default 10 /sbin/tc class add dev eth1 parent 1: classid 1:1 htb rate 100Mbps ceil 100Mbps burst 2k /sbin/tc class add dev eth1 parent 1:1 classid 1:10 htb rate 90Mbps ceil 100Mbps burst 2k prio 0 /sbin/tc class add dev eth1 parent 1:1 classid 1:11 htb rate 60kbps ceil 60kbps burst 2k prio 7 /sbin/tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.0.65 classid 1:11 /sbin/tc qdisc add dev eth0 root handle 1: htb default 10 /sbin/tc class add dev eth0 parent 1: classid 1:1 htb rate 10Mbps ceil 10Mbps burst 2k /sbin/tc class add dev eth0 parent 1:1 classid 1:10 htb rate 9.9Mbps ceil 10Mbps burst 2k prio 0 /sbin/tc class add dev eth0 parent 1:1 classid 1:11 htb rate 60kbps ceil 60kbps burst 2k prio 7 /sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip src 192.168.0.65 classid 1:11
