That was just a mistype i typed in actualy your test config for htb, 
modified for my expalme purposes :))
this is the actual config:

Also: whe I mark pakets for example only on OUTPUT chain, it will apply 
only to packets from me? so I should do it for in and out right?

Anyway with this config when I download from srchost1 (I use wget to 
measure) via ftp wget shows from 140 to 240 KB/s
and for srchost2 via http I get from 70 to 100 KB/s. nothing like I 
expected :)

Wouldn`t it prevent 1:1 from borrowing from 1: ? I think I`m 
missunderstanding the ceil. As I see it it is if I fe. have rate 100kbit 
and ceil 100kbit then 1:1 would go at at least 100kbit and can borrow 
100kbit from 1: . Which is in my case unwanted. I want to limit 1:1 to 
100kbit without abilyti to borrow. 1:100 and 1:101 could borrow from one 
another up to the max rate of 1:1 ( 100 kbit) that is what I want ot 
achieve.

thanks,

Anton

it will but also it will prevent 1:1 to lend anything.

no 100/100 is it can do 100 and 100 is also it;s maximal rate.
Cail should be greater or the same in respec to rate.

Hello,

After your explaining now I think I get the meaning of htb options and 
here is my config , which still sadly doesnt work. Downloads from 
srchost1 and srchost2 go at full speed, and are not shaped. Though 
counters for respective classes increase.

You are trying to shape downloads !? It will not work of course
in this setup. You can shape output only. Or what do you want to shape ?

ok I got it :)) that is what I suspected :)) finaly. that is common 
logic, I`m sorry, after reading some of the docs you go mad. my bad,

Question :
> > Has anyone ever managed to compile iproute2 from source,
> > running a 2.4.x kernel ?


I have also managed to solve it in another way..
Here is how ...



Solution 1:

Well I have managed to fix the compile error on a kernel 2.4.x

If we have a look at the file, /usr/src/linux/include/linux/if_ether.h 
that you get from the different kernels, we notice a change.

On 2.2.x kernel...
#define ETH_P_ECHO      0x0200          /* Ethernet Echo packet         */

On 2.4.x kernel...
#define ETH_P_PUP       0x0200          /* Xerox PUP packet             */



Q: How to fix it ?
 In the directory /lib of the source from the iproute2 tarball,
   is a file called, 'll_proto.c'
 In the file, there is an entry   '__PF(ECHO,echo)' on line 36.

A: Remove this line, and try to compile it again.

sorry for me previous mis-post.
It should have replied to the iproute compile problem chain.
