If have more than one interface need to specify it, for example:

ether-wake -i eth0 00:22:68:5E:34:06

  1. Doesn't work. I need the correct syntax. I am running CentOS 6.6 and just installed ethtool. It gives errors as follows:

    If I enter ether-wake 00:22:68:5E:34:06 it returns:

    Specify -i .

    If I enter ether-wake -i 00:22:68:5E:34:06 it returns:

    Specify the Ethernet address as 00:11:22:33:44:55.

    Please help!

  2. You have to specify interface if have more than one.

    For example

    ether-wake -i eth0 00:22:68:5E:34:06
