Hey gang. I have just written a client and server in C++ using sys/socket. I need to handle a situation where the client is still active but the server is down. One suggested way to do this is to use a heartbeat to periodically assert connectivity. And...

Does anyone have experience configuring drbd with heartbeat between 2 virtual linux machines (VMWare Infrastructure)?

Be careful that the aggregate bandwidth used isn't a drain on resources .
Broadcast a heartbeat every t using UDP; if you haven't heard from a machine in more than k*t, then it's assumed down.

I'm looking at implementing a "Heartbeat" process to do a lot of repeated cleanup tasks throughout the day.
This seemed like a good chance to use the Command pattern, so I have an interface that looks like:

I'm sorry for anyone who has to hear such bad news. As I understand it (I'm not a Dr.) you should see fetal heartbeat no later than 6 wks. Are you absolutely sure you're 8 wks? (I was 2 1/2 weeks off when I found out myself). Don't lose heart dear, the...
