Wondershaper nie ogranicza przepustowości

Jestem na serwerze dedykowanym (proxmox-ve-2.6.32: 3.4-165 (działające jądro: 2.6.32-42-pve)) z regułą 95. percentyla i chcę się upewnić, że go nie złamiesz. Mam łącze 1 Gb, a moja umowa oferuje mi 95. percentyl na 100 Mb. Chciałbym więc ograniczyć moje pasmo zawsze do 100 Mb.

Próbowałem użyć Wondershaper bez powodzenia i potrzebuję pomocy:

Jakieś pomysły?

Nie znalazłem sposobu na rozwiązanie tego problemu za pomocą Wondershaper, ale znalazłem inny sposób, aby zrobić to samo z Ethtool:

ethtool -s eth0 speed 100 duplex full

Ahem. Aby to wyjaśnić, nie robi to „tego samego”, chociaż osiąga to, co chcesz (ograniczając prędkość do 100 Mb / s). Ogranicza interfejs NIC do 100 Mb / s (skutecznie wyłączając Gigabit), ale nie zawsze jest dostępną opcją.
