Again this is for embedded system, freescale ARM processor, kernel 3.0.35-cm-fx6-4,
fs is using ubuntu 12.04。NetworkManager version is 0.9.4. So we have 2 systems for testing, 1. linux embedded system has 2 Gigabit ethernet ports 2. windows PC, we open 2 Dos windows keep on pinging eht0 and eth1. ping -t 10.50.1.1 ping -t 10.50.1.2 At the same time, we unplug eth ports in the linux side randomly and plug back. Now if this windows pc is windows 7, everything is fine. Now if it's windows 8 server, or windows xp, ping will fail. 1. you unplug eth0 in linux, "ping -t 10.50.1.1" will stop 2. plug back eth0, "ping -t 10.50.1.1" will work, but but "ping -t 10.50.1.2" stops, even though ethernet cable is still there. Any suggestions pls ? Thanks ! |
