Hi List, I am benchmarking freebsd 4.9, (also tried 4.11), two systems using nttcp 1.47 from ports thru a 100mb switch with two realtek 10/100 nics. I have 50 gre tunnels going thru 50 vpn tunnels between the two machines as well as quagga/ospfd with all addresses as neighbors. Using the following script I occasionally get in a state on the sending machine where it can send data but not receive it. I have a console that I run tcpdump on and I see packets go out but none come back, where on the other machine I see the packets come an a response go back. Any ideas as to what could be happening? for ((i=1;i<51;i++ )); do nttcp -T -w48 -n 32768 10.1.1.$((i*2))& done TIA, Steve
