烈火建站学院(LieHuo.Net)教程 实现远程开机的条件,要满足以下两条:首先,这个被远程开机的机器必需是在局域网内,并且你知道这台机器的MAC地址;其次,你的网卡支持网络唤醒功能,当然,现在大部分网卡都是支持网络唤醒的功能。检查你的网卡是否支持网络唤醒功能,只要在被远程开机的机器上执行 ethtool 命令,查看该机器网卡是否支持网络唤醒功能。
以下为引用的内容:
# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g [ 提示: g 表示已启动. d 表示禁用 ] Current message level: 0×00000001 (1) Link detected: yes |
提示:以上命令,需要拥有root权限,否则会有以下错误:
以下为引用的内容: $ /sbin/ethtool eth0 Settings for eth0: Cannot get device settings: Operation not permitted Cannot get wake-on-lan settings: Operation not permitted Current message level: 0×000000ff (255) Cannot get link status: Operation not permitted |
如果网络唤醒功能被禁用,则需要用下面的命令启动网络唤醒功能: # ethtool -s eth0 wol g
安装网络唤醒软件: # apt-get install wakeonlan
获取远程机器网卡的物理地址:
以下为引用的内容: # ifconfig eth0 Link encap:Ethernet HWaddr 00:16:k5:64:A9:68 [ Mac地址 ] inet addr:192.168.6.56 Bcast:192.168.6.255 Mask:255.255.255.0 inet6 addr: fe80::216:17ff:fe6b:289/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3179855 errors:0 dropped:0 overruns:0 frame:0 TX packets:2170162 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3832534893 (3.5 GB) TX bytes:390304845 (372.2 MB) Interrupt:17 |
通过以下命令,实现远程开机: # wakeonlan 00:16:k5:64:A9:68
