机房服务器远程开关机

1.确定服务器是否支持远程开机

[root@ncapp ~]# ethtool eth0
Settings for eth0:
 Supported ports: [ TP ]
 Supported link modes:   10baseT/Half 10baseT/Full 
                         100baseT/Half 100baseT/Full 
                         1000baseT/Full 
 Supported pause frame use: Symmetric
 Supports auto-negotiation: Yes
 Advertised link modes:  10baseT/Half 10baseT/Full 
                         100baseT/Half 100baseT/Full 
                         1000baseT/Full 
 Advertised pause frame use: Symmetric
 Advertised auto-negotiation: Yes
 Speed: 1000Mb/s
 Duplex: Full
 Port: Twisted Pair
 PHYAD: 1
 Transceiver: internal
 Auto-negotiation: on
 MDI-X: Unknown
 Supports Wake-on: pumbg
 Wake-on: g
 Current message level: 0x00000007 (7)
          drv probe link
 Link detected: yes
[root@ncapp ~]#

可以看到，ethtool把网卡的信息全部列出，我们只关心其中的这两项：

Supports Wake-on: pumbg

Wake-on: d

如果 wake-on一项值为d，表示禁用wake on lan；如果值为g，表示启用wake on lan。

因为此机器禁用了wake on lan，所以用下面的命令来启用它：

[root@localhost lhd]# ethtool -s eth0 wol g

再用ethtool命令进行查看，会发现：

Wake-on: g

2.得到目标主机的IP地址和MAC地址

[root@ncapp ~]# ifconfig

3.准备好远程开机软件

在局域网中另一台电脑上安装远程开机软件，其下载地址为：

https://www.depicus.com/wake-on-lan/wake-on-lan-cmd

4.远程开机

如要开192.168.150.245这台机器，命令如下：

wolcmd 1c1b0d02e587 192.168.150.245 255.255.255.0 8900

5.Wake On Lan Command Line

这是上面的补充：

1）The command line tool wolcmd is run from a dos prompt. The syntax is as follows:

wolcmd [mac address] [ip address] [subnet mask] [port number]

2）you can also do a local broadcast if you are running on an internal network thus

wolcmd [macaddress] 255.255.255.255 255.255.255.255 4343

where mac address is the unique address of the network card. To find the mac address of a card you can either open the computer and read the address on the sticker on the card or much easier is, if you are using TCP/IP, ping the machine from a dos prompt (ping [machine name or ip number] i.e. ping delphi or ping 10.43.43.43) then issue an arp command (arp -a) which will list the ip number and physical address of the card.

If the port number is not specified it will default to port 7

Running from a batch file

Simply add multiple entries thus:

wolcmd 009027a324fe 195.188.159.20 255.255.255.0 8900 
wolcmd 009024a731da 212.86.64.31 255.255.255.0 8900
