Re^2: How do I make a tcp socket heartbeat?

Thanks for the help!

In fact, I'm pretty new to both perl and TCP connections. I used IO :: Socket because I found the most examples out there, but I found it very difficult to understand how everything works with it. Maybe in the future I will study more and try to do the script again, writing the complete server.

I tested your example using Mojo and it worked very well, exactly as I wanted. Thanks very much!

Yes, the select(2) system call is (one of) the classic ways to do it. "Classic" both in the good and bad sense: good because understanding it will help you understand how lots of servers work and how things work on a lower level, not so good because nowadays I'd consider it fairly low level, so for just getting stuff done, as I said IMHO event loops are a good approach.
