Server sends knock-knock, client does something.by Anonymous Monk |

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question: Sorry all, I'm kind of new to network programming, and not entirely sure where to start on this one. Basically, just need someone to point me in the right direction. I have a client daemon that does stuff on the client. As it is set up now, it does what it needs to do on a timed interval (every 30 minutes). However, I'd very much like for the server to be able to send something to the client (a packet, something), and for the client to be waiting for this. Then, as soon as the client receives from the server what it is waiting for, it kicks into action. Basically, Client sitting, waiting... ho-humServer sends knock-knock. Client wakes up, kicks into action and does what it needs to do. Any help with this is greatly appreciated. A nudge in the right direction would even be great. Thanks all!
