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 # lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.6.1810 (Core) Release: 7.6.1810 Codename: Core Let me know if you need some help, Eliezer ---- Eliezer Croitoru Linux System Administrator Mobile: +972-5-28704261 Email: eliezer@xxxxxxxxxxxx -----Original Message----- From: CentOS <centos-bounces@xxxxxxxxxx> On Behalf Of Gregory P.

Has anyone else had this problem, and if so any luck with a fix?
