Ethtool是用于查询及设置网卡参数的命令。
概要：
ethtool ethX      //查询ethX网口基本设置
ethtool –h        //显示ethtool的命令帮助(help)
ethtool –i ethX    //查询ethX网口的相关信息
ethtool –d ethX    //查询ethX网口注册性信息
ethtool –r ethX    //重置ethX网口到自适应模式
ethtool –S ethX    //查询ethX网口收发包统计
ethtool –s ethX [speed 10|100|1000]\         //设置网口速率10/100/1000M
[duplex half|full]\           //设置网口半/全双工
[autoneg on|off]\            //设置网口是否自协商
[port tp|aui|bnc|mii]\         //设置网口类型
[phyad N]\               
[xcvr internal|exteral]\
[wol p|u|m|b|a|g|s|d...]\
[sopass xx:yy:zz:aa:bb:cc]\
[msglvl N]

举例：
1）[root@linux /]# ethtool eth1
   Settings for eth1:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: on
        Supports Wake-on: umbg
        Wake-on: d
        Link detected: yes
2）[root@linux /]# ethtool -i eth1
   driver: e1000
   version: 5.0.43-k1
   firmware-version: N/A
   bus-info: 06:08.1
3）[root@linux /]# ethtool -S eth1
   NIC statistics:
     rx_packets: 58068300
     tx_packets: 87124083
     rx_bytes: 1589713008
     tx_bytes: 2165825901
     rx_errors: 0
     tx_errors: 0
     rx_dropped: 0
     tx_dropped: 0
     multicast: 0
     collisions: 0
     rx_length_errors: 0
     rx_over_errors: 0
     rx_crc_errors: 0
     rx_frame_errors: 0
     rx_fifo_errors: 0
     rx_missed_errors: 0
     tx_aborted_errors: 0
     tx_carrier_errors: 0
     tx_fifo_errors: 0
     tx_heartbeat_errors: 0
     tx_window_errors: 0
4）[root@linux /]# ethtool -s eth1 autoneg off speed 100 duplex full

相关：
1）[root@linux /]# which ethtool
    /sbin/ethtool
2）[root@linux /]# rpm -qf /sbin/ethtool
   ethtool-1.6-5
3）怎样使ethtool设置永久保存在网络设备中？
   解决方法一:
    ethtool设置可通过/etc/sysconfig/network-scripts/ifcfg-ethX文件保存,从而在设备下次启动时激活选项。
例如：ethtool -s eth0 speed 100 duplex full autoneg off
此指令将eth0设备设置为全双工自适应，速度为100Mbs。若要eth0启动时设置这些参数, 修改文件/etc/sysconfig/network-scripts/ifcfg-eth0 ，添加如下一行:
 ETHTOOL_OPTS="speed 100 duplex full autoneg off"
解决方法二:
将ethtool设置写入/etc/rc.d/rc.local之中。

你只需要有一个 GIF 或者 PNG 的方形图片，该网站就可以帮你生成效果还不错的 ico 图标，效果比我在国内找的一些网站好多了，支持透明背景。

MATRIX="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz~!@#$%^&*()_+="

while [ "${n:=1}" -le "$LENGTH" ]
do
        PASS="$PASS${MATRIX:$(($RANDOM%${#MATRIX})):1}"
        let n+=1

        echo "$PASS"
exit 0

或用mkpasswd

echo $RANDOM,产生数字串
