[LARTC] Simple Beginner Question - allocating 64k

[LARTC] Simple Beginner Question - allocating 64k

[Carl Spies]

Hi there

Please be patient - I'm a newbie at this.

Have an internet connection on eth0 - 64K
so  eth0 = 216.139.165.7
and eth1 = 192.168.0.1

have 4 pcs connected to a hub on eth1
the pc's are 192.168.0.11 and 22 and 33 and 44

I want to allocate  4kb to 192.168.0.11
               and  4kb to 192.168.0.22
               and  8kb to 192.168.0.33
               and 32kb	to 192.168.0.44

so this is a total of 48kb and the rest is used on the server 10.0.0.80

Also - want to make sure that 192.168.0.11 never takes more than 4kb at 
any time.

No fancy stuff like separating http and smtp and things.

What's the simple most elegant way of doing this on eth1.

Yipes sorry - you're right - I meant 192.168.0.1

(it's 3am and i'm only knitting with one needle) :)

So please be nice :)

How can your internal server be 10.0.0.80 when the rest of your
internal LAN is 192.168.0.nnn?

Hi there

Please be patient - I'm a newbie at this.

Have an internet connection on eth0 - 64K
so  eth0 = 216.139.165.7
and eth1 = 192.168.0.1

have 4 pcs connected to a hub on eth1
the pc's are 192.168.0.11 and 22 and 33 and 44

I want to allocate  4kb to 192.168.0.11
               and  4kb to 192.168.0.22
               and  8kb to 192.168.0.33
               and 32kb	to 192.168.0.44

so this is a total of 48kb and the rest is used on the server 10.0.0.80

Also - want to make sure that 192.168.0.11 never takes more than 4kb at 
any time.

What's the simple most elegant way of doing this on eth1.

Create a HTB qdisc, add a ceiled class of 64K, add 5 classes with the 
appropriated rate (4 for the LAN's : 4,4,8,32 kb and 1 for the server 16kb) 
with ceil = 64kb.  But ceil 192.68.0.11 to 4kbit.   Mark the packets on eht1 
for all ip's with a different mark and use the fw filter on eth0 to put the 
traffic in the right class.
You can do the same with CBQ of you want.  You need to patch the kernel 
before you can use the HTB qdisc.

Here is an addapt of my script but you'll have to compile htb into the
kernel and iproute2; see also

http://luxik.cdi.cz/~devik/qos/htb/htbman.htm


qdisc->class_limit_48---class 1   4  Kb -> qdisc sfq
                                       \_class 2   4 Kb -> qdisc sfq
                                       \_class 3   8 Kb -> qdisc sfq
                                        \_class 4  32 Kb -> qdisc sfq

... tc filter to put IP in classes. It should go like this:

tc qdisc add dev eth1 root handle 1: htb default 10

tc class add dev eth1 parent 1: classid 1:1 htb rate 48kbit ceil 48kbit
burst 1k

tc class add dev eth1 parent 1:1 classid 1:10 htb rate 4kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:11 htb rate 4kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:12 htb rate 8kbit ceil 48kbit
burst 1k
tc class add dev eth1 parent 1:1 classid 1:14 htb rate 32kbit ceil
48kbit burst 1k

tc qdisc add dev eth1 parent 1:10 handle 20: sfq perturb 10
tc qdisc add dev eth1 parent 1:11 handle 30: sfq perturb 10
tc qdisc add dev eth1 parent 1:12 handle 40: sfq perturb 10
tc qdisc add dev eth1 parent 1:14 handle 50: sfq perturb 10



tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.11 flowid 1:10
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.22 flowid 1:11
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst
192.168.0.33 flowid 1:12
