Tcpreplaying using VMware
- by Methos
This is more like a testbed setup question.
I want to use VMware to debug some networking code in the linux kernel in the VM. My VM has two network interfaces. What I want to do is replay the capture file in the host and receive the packets in the VM. My problem is I do not see replayed packets in the VM.
I am running VMware and tcpreplay on the host as sudo. Hence I think there should not be any problem access devices files.
I am running VMware workstation 7.0
a. I first began with Custom networking as that provides option of creating your own virtual network name. I wrote /dev/vmnet3 and /dev/vmnet4 for the two interfaces respectively. However, after booting the guest, I did not see any of these interfaces or devices files (in /dev) created on the host.
b. Then I tried 'Host Only', but that does not show what bridge/device file is associated with the interface.
c. Finally I tried bridged networking mode.
I see vmnet1, vmnet8 and vboxnet0 on the host. I have tcpreplayed the capture file on each of these interfaces, for all the above three cases. I tried to capture packets in the VM using "tcpdump -i any". However, I do not see any packets.
Any ideas/pointers?
