Windows Forum / Virtual PC / April 2008Monitoring the (inter)net traffic of virtual PC's from the host?
Hi, Im currently using a couple of virtual pc's to access the internet for services such as bbciplayer, which i then transfer to my main pc, and ultimately stream to the xbox 360. But Im trying to monitor the usage of the traffic of the virtual pc from the host, but there is no sign of any activity. none of the processes are showing any network activity, and i know my net connection is maxed out. I've tried netlimiter and cfosspeed to try to monitor is with no sucess, can anyone give me any pointers.? Thanks in advance for any help. You won't see any activity in the host because the traffic does not go through the host's IP stack. Packets with the MAC address of a NIC in a guest are intercepted by Virtual Machine Network Services at the hardware address level and directed to the IP stack in the quest. > Hi, > [quoted text clipped - 13 lines] > > Thanks in advance for any help. So in effect there would be no way to monitor it from the host as the virtual pc has its own TCPip Stack. Even though the its ruinning as a process on the host. I didnt realise this, its scary, a virus could use this to completely bypass the firewall and avoid detection. Many thanks for the answer. > You won't see any activity in the host because the traffic does not go > through the host's IP stack.
