| | | | | | | waiting around long enough for the heartbeat response to come back. Since we only heartbeat when there isn't any output (in qarsh), taking up to a second won't hurt. After doing some tests I'm changing the recvfrom to recvfrom sleep to 1000 usec and retrying up to 40 times.

* Add cookies to the heartbeat packet for added safety.v1.10-1Nate Straz2008-09-231-0/+2
| | | | | | | | | Two factors forced this change. 1. ports were being re-used so quickly that we could get lingering packets from past hosts when getting the btime for a new host. 2. We can't control which IP a btime response is sent from if a system has more than one interface. Adding a cookie allows us to know that a response came from whom we sent it.
