At this moment all connections seem frozen. Telnet, HTTP, and NFS. For development i have nfs root fs. There is a ioctl() that does the equivalent of "brctl addif br0 eth0" That cuts all the connections for a few seconds. nfs: server 192.168.10.51 not responding, still trying br0: topology change detected, propagating br0: port 1(eth0) entering forwarding state nfs: server 192.168.10.51 not responding, still trying nfs: server 192.168.10.51 OK nfs: server 192.168.10.51 OK Then everything is OK.. Is there anyway i can fix this, so my applicaion goes ahead at full speed? using libnl i tried flushing the ARP cache on all devices, but it didn't seem to help. Thanks -- Karl.
