 Posted: Fri Mar 12, 2004 10:33 pm Post subject: Limiting outbound ports bandwith |
 |
|
Many upon many threads about bandwith limiting...wondershaper, cbq...etc
I have yet to find a simple script that does what the title says...Limit outbound bandwith on certain ports.
Example: I have a 62kb/s upload. If I set wondershaper to limit me at 50kb/s, other computers on the lan get great pings becuase there is 12kb/s left on the line. But since wondershaper is limiting _my_ computers available pipe, pings are just as bad with and without wondershaper.
Basically I just want to limit ftp (I'm behind a router so I have to use passive mode), http, bittorent, and maybe a few other things to have only 50kb/s combined. Any other network (such as a game) can use how much ever it needs. Is there such a beast or am I stuck reading through the manuals and figuring everything out myself?
I just figure other people have had similar needs as I and they either know of a script or could show me theirs.
Thanks in advance. |

the trick is to use QoS. It's a bit tricky to get set up. Try READING the wondershaper set up.
You can arrange all outgoing traffic in different queues and give prioritys for them. If you want I can post my QoS script (based on the wondershaper). It gives priority to interactive traffic (telnet, ping etc) and gives HTTP and stuff the rest. |

Can you post that QoS script?
Thank you,

if something is not clear, ask!
It doesn't do what you asked for, but demonstrates the QoS, so you'd be able to write your own
| Code: |
# QoS
#####
# Clean up existing qdiscs (should not be none, since the interface is just
# up, but anyway) and suppress errors
$TC qdisc del dev $IFNAME root > /dev/null 2> /dev/null
$TC qdisc del dev $IFNAME ingress > /dev/null 2> /dev/null
# QoS UPSTREAM
##############
# Root gets HTB, default in 1:20
$TC qdisc add dev $IFNAME root handle 1: htb default 20
# Max rate is $UPLOAD_RATE
$TC class add dev $IFNAME parent 1: classid 1:1 htb \
rate ${UPLOAD_RATE}kbit burst 6k
# High prio class 1:10
$TC class add dev $IFNAME parent 1:1 classid 1:10 htb \
rate ${UPLOAD_RATE}kbit burst 6k prio 1
# Low prio class 1:20 (default)
$TC class add dev $IFNAME parent 1:1 classid 1:20 htb \
rate $[9*$UPLOAD_RATE/10]kbit burst 6k prio 2
# Give them stochastic fairness
$TC qdisc add dev $IFNAME parent 1:10 handle 10: sfq perturb 10
$TC qdisc add dev $IFNAME parent 1:20 handle 20: sfq perturb 10
# Filters
# -------
# TOS Minimum Delay in 1:10
$TC filter add dev $IFNAME parent 1: protocol ip prio 10 u32 \
match ip tos 0x10 0xff flowid 1:10
# ICMP (IP protocol 1) in 1:10
$TC filter add dev $IFNAME parent 1: protocol ip prio 10 u32 \
match ip protocol 1 0xff flowid 1:10
# ACK packets in 1:10
# ACKs are:
# TCP (ip protocol 6)
# Short header (20 bytes)
# ACK bit set (0x10/0xff at TCP-hdr+14)
# No payload (total length < 64B at 2)
$TC filter add dev $IFNAME parent 1: protocol ip prio 10 u32 \
match ip protocol 6 0xff \
match u8 0x05 0x0f at 0 \
match u8 0x10 0xff at nexthdr+14 \
match u16 0x0000 0xffc0 at 2 \
flowid 1:10
# Rest ends up in 1:20
# QoS DOWNSTREAM
################
# ingress policer
$TC qdisc add dev $IFNAME handle ffff: ingress
# filter ALL (0.0.0.0/0)
$TC filter add dev $IFNAME parent ffff: protocol ip prio 50 u32 \
match ip src 0.0.0.0/0 police rate ${DOWNLOAD_RATE}kbit burst \
10k drop flowid :1

A lot of that looks similar to wondershaper (which I have read) but all of it is foreign to me.
I _could_ go read through all the docs and figure out what everything is, but I was just hoping someone that has read them had made a script (or has a script) similar to my needs. |
