A ReadMe.md

Install service

Since this linux is an old version, it still use sysv scripts for service management. To run tailscaled as a daemon (service), follow the procedure below.

1. Copy the script to /etc/rc0.d/K20tailscaled. The script is mainly borrowed from this gist.
2. Adjust the script as appropriate.
3. Reboot the system via reboot.
4. Check the service is started.
   1. By listing all services with service --status-all.
   2. Or check the status of this specific service with service tailscaled status. If it's alright, you should get the following output.

   [ ok ] tailscaled is running.

After the daemon service is started, we can start tailscale using command like this.

tailscale up --auth-key ${TS_KEY} --advertise-routes=192.168.0.0/16
