原文地址：linux 测试网速的相关工具 作者：mxcai2005

1. #  iptraf -g   //这个最直观

2. iperf 　Iperf 是一个网络性能测试工具。Iperf可以测试最大TCP和UDP带宽性能。Iperf具有多种参数和UDP特性，可以根据需要调整。Iperf可以报告带宽，延迟抖动和数据包丢失

TCP:
server(pc):  iperf -s -i 1
client(ls1b):  iperf -t 20 -i 1 -c 192.168.1.167 (pc-ip)

UDP:
server(pc): iperf  -u -s -i 1
client(ls1b): iperf -t 10 -i 1 -u -b 1000M  -c 192.168.1.90

3. #  ifconfig -a
eth0:Link encap:Ethernet  HWaddr 00:1e:64:63:ab:fe  
          inet addr:192.168.3.103  Bcast:192.168.3.255  Mask:255.255.255.0
          inet6 addr: fe80::21e:64ff:fe63:abfe/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:70283 errors:0 dropped:0 overruns:0 frame:0
          TX packets:46701 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:73276012 (73.2 MB)  TX bytes:6267375 (6.2 MB)

4. #  mii-tool -w -v  //更详细的用法 man mii-tool


5. ethtool是用来显示和更改网卡设置的工具 更详细的用法 man ethtool
# ethtool eth0   //显示网络端口设置功能
