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

roduct info: vendor 00:50:43, model 11 rev 0

asic mode: autonegotiation enabled

asic 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:

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

h wamdm*
