Hi, a tcpdump on the loopback device says: ================================= tcpdump: listening on lo 10:40:45.589797 backup03m.1008 > backup03m.10080: udp 117 (DF) 10:40:55.482650 backup03m.1008 > backup03m.10080: udp 117 (DF) 10:41:05.482671 backup03m.1008 > backup03m.10080: udp 117 (DF) 6 packets received by filter 0 packets dropped by kernel ================================= Shouldn't there be responds from port 10080 to 1008? Nice greetings, Christoph
