[Udpcast] Exiting udp-receiver or reboot machine after a certain amount of time without transfer activity

Hello, I am curious whether there is an commandline option which could instruct udp-receiver to exit after a certain amount of time without any udp-sender activity or generally when the transfer process doesn't start. At least I could not find anything in the documents. We use udpcast together with PXE-boot and sometimes some machines are simply not responding to the sender (why is yet unclear). After manually restarting the machines it is usually the case that the machines to be imaged are responding again and everything is well. Unfortunately it could be the case that there are machines to be imaged which are placed in locked rooms and so it is impossible to restart them manually. Regards Jens
