homelab-ping

This is a small project targeting certain issues related to my Homelab computer.

Specifically, the Intel i225-V Ethernet controller has an issue that causes the PC to randomly lose the network card or connectivity after a few weeks. I haven't found a reliable solution and am unable to restart it when I'm not at home.

This program can periodically ping the router and will restart the PC if it loses connection after multiple attempts.

This program may unexpectedly restart your computer and may cause data loss.

Installation

This program only supports Linux and requires the root user.

go install github.com/mudkipme/homelab-ping
