Não encontrei o caminho para corrigir esse problema com o Wondershaper, mas descobri uma outra maneira de fazer o mesmo com o ethtool:
ethtool -s eth0 speed 100 duplex full
Eu estou em um servidor dedicado (proxmox-ve-2.6.32: 3.4-165 (executando kernel: 2.6.32-42-pve)) com uma regra de percentil 95 e quero ter certeza de não quebrá-lo. Eu tenho um link de 1gbit e meu contrato me oferece um percentil 95 em 100mbits. Então eu gostaria de limitar minha largura de banda sempre a 100 mbits.
Eu tentei usar o Wondershaper sem sucesso e preciso de ajuda:
