Have you tried using some other application from the system running guacd to send the WoL packet to see if the packet is being sent/generated correctly from the guacd system and can successfully wake the computer? I know that you've set it up on a different system, but you should try it from the same system running guacd just to make sure that it works from that specific system. > - Not sure if you're running guacd in Docker or not, but, if you are, there > are additional things to consider regarding how you attach the guacd > container to the network and send the packets. > > *I don't running guacd in Docker* > > - If you have any firewalls, including host-based firewalls, you need to > make sure the firewalls are configured properly. > *My firewall is cofigured properly* > > - Have you done any packet sniffing to see if the magic packet is going > out? > *I don't know how make this...* > > > You can use tcpdump (yum install tcpdump) to sniff traffic on the system running guacd and filter for the wake-on-lan packet to see if the packet is going out correctly and has the correct contents. https://unix.stackexchange.com/questions/506582/how-to-capture-wol-packets -Nick
