Hi

I'm using ROS Melodic.

I have 2 devices, one as Master, one as Slave. The master boots earlier and runs roscore. A few seconds later, the Slave boots and runs its node via rosrun in /etc/rc.local. This setup works with no problem. BUT, I want the Slave to be able to re-connect to Master when the Master reboots (for any reason).

What should I do?
