problem se shaperem

[David Trcka]

Zdravim,

mam nasledujici problem se shaperem:

Mam stroj A se shaperem na 33600 spojeny ethernetem na stroj B.
Konfigurace sitovych rozhrani i shaperu je bezna, vsechny hodnoty (krome IP
adres pochopitelne) jsou vychozi (MTU apod.).

Na stroji A dam ping B -s 4000  --> jede OK:
PING 194.228.42.126 (194.228.42.126): 4000 data bytes
4008 bytes from 194.228.42.126: icmp_seq=0 ttl=64 time=608.8 ms

...atd

Na stroji A dam ping B -s 5000  --> dela toto:
PING 194.228.42.126 (194.228.42.126): 5000 data bytes
5008 bytes from 194.228.42.126: icmp_seq=0 ttl=64 time=862.1 ms

5008 bytes from 194.228.42.126: icmp_seq=14 ttl=64 time=3449.0 ms
...konec, dalsi pingy v tomto pripade neprojdou. Navic uvazne jakakoliv
dalsi komunikace ke stroji B, ktera krome toho do te doby jela, dokud
neprerusim ping.

Totez dela i opacne pri pingu z B na A.
Dela to na ruznych verzich shaperu i jadra pocinaje 2.0.34 konce 2.0.36.
Zhruba tusim, ze to souvisi s tim, ze na nastavene rychlosti jaksi neni
mozne v rozumne dobe odeslat treba petikilovy paket. Jenomze co s tim,
takove pakety museji projit!

Mate nekdo nejaky napad?
