Hi, Even though I followed "Setting Up a Virtual Testing Environment" carefully in Ubuntu, I couldn't connect btw NOX and OpenFlow like followings. ----------OpenFlow---------- . . Jul 22 22:18:23|00312|rconn|WARN|tcp:10.0.2.2:2525: connection dropped (No route to host) Jul 22 22:18:23|00313|rconn|INFO|tcp:10.0.2.2:2525: waiting 15 seconds before reconnect Jul 22 22:18:35|00314|fail_open|INFO|Still in fail-open mode after 1218 seconds disconnected from controller Jul 22 22:18:38|00315|rconn|INFO|tcp:10.0.2.2:2525: connecting...

Besides, why should we begin OpenFlow after NOX. If I tried to change the beginning order btw NOX and OpenFlow, it doesn't work. Why..? And, I also failed to connect btw host1 and host2 like following. ---------host1---------------- hda:~# ping 10.10.0.2 PING 10.10.0.2 (10.10.0.2) 56(84) bytes of data. From 10.10.0.1 icmp_seq=1 Destination Host Unreachable From 10.10.0.1 icmp_seq=2 Destination Host Unreachable . . ------------------------------ ---------host2---------------- hda:~# ping 10.10.0.1 PING 10.10.0.1 (10.10.0.1) 56(84) bytes of data. From 10.10.0.2 icmp_seq=1 Destination Host Unreachable From 10.10.0.2 icmp_seq=2 Destination Host Unreachable . . ------------------------------ How can I solve this problem? Thank you. ---Kate
