I'm experimenting with using my Pi as a Wake on LAN Server but only having partial success.
I'm using a RPi 4 and two regular x86-64 desktop PC's. The Pi is running the latest RPi OS Lite and the PC's are running Ubuntu Mate 20.04 an Linux Mint 20.1 respectively. They are all on the same wired network.
I have a file,
maclist,listing the MAC and IP addresses of the 2 PC's:
1a:2b:3c:4d:5e:6f 192.168.1.101 ff:ee:dd:cc:bb:aa 192.168.1.103
I run the command on the RPi:
wakeonlan -f maclist
The machine at 192.168.1.101 starts up fine, however the machine at 192.168.1.103 does not.
I can then
ssh from the pi to 192.168.1.101 and issue a
wakeonlan command from there and machine 192.168.1.103 wakes up fine. This of course serves as a workaround but it is not my preference. I think it should work - any ideas on what I am doing wrong?
