PcapHandle not Closed if no packets received. How to forceful close handle
pratmodi opened this issue · comments
We are implementing dumping by packetcount based on filter by port. The call to listener.gotPacket(handle.getNextPacketEx()) keeps on listening for packets. There's a readtimeout too, but the call is stuck at listener.gotPacket(handle.getNextPacketEx()). We have already tried putting handle.close() in various places like finally,etc but it never gets closed. If we are sending packet traffic manually through postman at given port, then the packets get dumped and handle & dumper both get closed and work fine. Please suggest how to close the handle when there is no traffic. Again, we have kept readtimeout of 20 seconds but that also doesnt work. Following is the code we have written -
if (dumper.isOpen()) {
listener.gotPacket(handle.getNextPacketEx());
}
