ubuntu一些操作汇集

（1）查看网速的命令：

1：方法一

wamdm@WAMDM18:~$ sudo /sbin/mii-tool -v

结果显示如下：

SIOCGMIIREG on eth0 failed: Input/output error
SIOCGMIIREG on eth0 failed: Input/output error
eth0: negotiated 1000baseT-FD flow-control, link ok
  product info: vendor 00:50:43, model 11 rev 0
  basic mode:   autonegotiation enabled
  basic status: autonegotiation complete, link ok
  capabilities: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
  link partner: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

2：方法二：查看网卡状态的命令

wamdm@WAMDM15:~$ sudo ethtool eth0
[sudo] password for wamdm:
Settings for eth0:
        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

（2）不同机器之间拷贝文件的命令scp

如：从wamdm2拷贝eclipse目录到wamdm14机器的/home/wamdm/目录下
wamdm@WAMDM2:~$ scp -r eclipse wamdm@wamdm14:/home/wamdm/
（3）利用putty从一台机器登录到另一台机器

ssh wamdm*
