如何在Linux上以編程方式獲取網絡接口速度？

我想知道網絡連接信息中顯示的速度，例如， 100Mb/s，10Mb/s，而不是可用帶寬。提前致謝！如何在Linux上以編程方式獲取網絡接口速度？

發現編程閱讀這些信息並對其進行解析，尋找100BASE-TX或類似

# mii-tool -v eth0 
eth0: negotiated 100baseTx-FD flow-control, link ok 
    product info: vendor 00:00:20, model 32 rev 1 
    basic mode: autonegotiation enabled 
    basic status: autonegotiation complete, link ok 
    capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD 
    advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control 
    link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

此外，在同一篇文章中，你可以使用這個，尋找「速度：」行

#ethtool eth0 

Settings for eth0: 
    Supported ports: [ TP MII ] 
    Supported link modes: 10baseT/Half 10baseT/Full 
          100baseT/Half 100baseT/Full

    Advertised link modes: 10baseT/Half 10baseT/Full 
          100baseT/Half 100baseT/Full 
    Advertised auto-negotiation: Yes 
    Speed: 100Mb/s 
    Duplex: Full

如果你想要做的是，在C代碼，查找mii-tool.c

信息通過查詢適當的ioctl函數完成，mii-tool.c提供了該示例。 – rasjani 2009-06-13 17:44:27
