Using Trex to generate traffic to a windows PC

[michael...@gmail.com]

Hello,

I am looking for a way to generate traffic to test an application on a Windows endpoint that would filter that traffic.
Is that possible with Trex.
From what I've read so far it appears that installing Trex is only possible onto Linux machines or VM not Windows.
That would be fine if I can then use it to send the traffic to a Windows endpoint to be consumed by my application.
I'd appreciate any input, thanks
Michael

Hi,

You can use Virtual Box, that would give Linux inside Windows.
You can setup it to bridge interfaces Linux <-> Windows.
Use virtual E1000 inside Linux.

Thanks,
Yaroslav

Thanks Yaroslav,
Would you have more detailed instructions available on how to set up the bridge interface?
I am running Trex on a Fedora_21 VM in Virtual Box, my PC is running Win10 outside VB.
Cheers
Michael

Hi, 

Another alternative, 

with Windows 10 you can run Linux docker in native manner. 

Have a look here

I set up a Bridged Adapter as suggested in the Fedora VM under Virtual Box.
I then start T-rex server using different profiles from the cap2 folder.
While running and sending traffic I am attempting to capture it on the other side in Wireshark in my host Windows machine.
Sometimes the traffic does show up, sometimes it does not.
Question 1: I wonder why the inconsistency?
Also when traffic does show up it shows up as lots of Malformed packets in Wireshark.
I took the pcap file that the yaml file is using inside it (eg http_simple.yaml has delay_10_http_browsing_0.pcap inside it so I'm assuming it uses this pcap to generate traffic), opened the pcap in my windows host in Wireshark and it looks like normal traffic, no Malformed packets.
Question 2: Can you help with why the same traffic when sent through T-Rex and captured with Wireshark in my host shows up as a long list of Malformed packets?
Thanks
Michael

Hi Michael,

Could you provide more info about what is malform?

Capfile would be good too

I'll try to capture and post.
Right now I'm struggling with getting data flowing to my windows host again for some reason.
When I open wireshark there expecting traffic from the trex server running inside the VM guest in VirtualBox ... I only see ARP request in Wireshark
Who has 2.2.2.2? Tell 1.1.1.1
Who has 1.1.1.1? Tell 2.2.2.2
I'm guessing I messed up something but not sure what :(
