Lab 3.1
Hi,
When I run the command on the main VM:
$ tcpdump -w /tmp/secondary-http.pcap -i enns33 port 80 and host secondary.example.com
I get the VMWare error in a dialogue box:
The virtual machine's operating system has attempted to enable promiscuous mode on adapter 'Ethernet1'. This is not allowed for security reasons.
Please go to the Web page "http://vmware.com/info?id=161" for help enabling promiscuous mode in the virtual machine.
But I don't understand what's wrong because I su'd to root to do the command and that should allow promiscuous mode. Am I missing something?
The .pcap file is made but nothing's been written to it, and no activity registered by tcpdump.

Hello, Quick question, "enns33" is that supposed to be "ens33", mine is "ens33".
We can reduce the selection arguments and output directly to the screen with "sudo tcpdump -i ens33" , then wait for a few minutes, there may not be much traffic.
The very first time I ran "sudo tcpdump -i ens33" I got a popup message like yours, oddly, it vanished on its own and started to show me the packets.The article mentioned is about using Linux for the "host" and "client" , please verify this is the case.

Thanks for the reply.
Yes, typo, is ens33.
I find the plain sudo tcpdump -i ens33 works fine, but when I do the command that outputs to the file I then get the error dialogue and no activity is shown or logged. And then afterwards the plain sudo tcpdump -i ens33 command doesn't work also.
There's a few things I've worked out to try and will get back to you if I'm stumped. Many thanks.
