First, you will need to open something to ssh to the server with e.g command prompt, terminal or PowerShell.
Once there, you will need to ssh into your server. Type in anything after an ">" symbol and fill in any information in "[]".
> ssh [username for vcore]@[IP address of your server]
[input vcore password when prompted]
If you type "help" here, you will be able to see all the commands available to you.
To take the packet capture, we will be using "tcpdump" and you will have 60 seconds to complete your action.
> tcpdump start
(go and complete the action you have been asked to do by the Support Team in your browser)
> tcpdump stop
> exit
> scp [username for vcore]@[IP address of your server]:/tmp/dump.pcap [rename your pcap].pcap
[input vcore password when prompted]
If you look in your current working directory, you should be able to find your packet capture to send to Support.
