Question

I’m trying to periodically check out if several linux machines are alive.

My idea is to have a main computer that receives a periodic message from every machine, so if any of them stops messaging, the main one will know something’s going wrong with that particular equipment.

I want to make it as “lite” as possible, I mean, using the less data transmission possible, because some of the machines I want to look after are placed on installation with a not so good internet connection. So, if it’s possible, I’ll prefer not to use email or ftp.

Any idea?

Thanks in advance.

You should use a dedicated piece of software for monitoring your infrastructure. Inventing something from scratch will probably take longer and be much less powerful than such a product. nagios for example is something that is commonly used for this purpose.
