Everyone,

I have not been able to get ether-wake to work waking up other CentOS 7.6 machines after the upgrade to CentOS 7.6. Has anyone else had this problem, and if so any luck with a fix?

  • we have no problem with ether-wake under CentOS 7.6 . Has been working for us as under earlier versions.

    Years ago, we had to replace some RHEL-provided ethernet driver modules with ElRepo-provided ones for WOL to work. So check out ElRepo for newer drivers for your cards.

    HTH,

  • Can you be more specific about the hardware?
    I have a setup of DELL desktop, DELL Server SuperMicro Server and couple other devices. I am using from a cgi script the next on one server to wake the other:
    /usr/bin/sudo /usr/sbin/ether-wake “XY::XY” -b && echo 1

    All of my servers have Intel PRO 1Gbit ethernet nics(2,4,1.. ports per machine).

    To make the Desktop wakeup I had to do the next:
    – Reset the bios settings to default
    – Reconfigure the bios to allow remote wake up
    – Disable couple Power related special sleep settings(on the desktop)
    – Make sure that the switch can handle 10Mbps connection (since most of these nics stay at low power and low speed waiting for WOL packets).

    Works for me on at-least three machines with CentOS 7.6
