When following lab instructions, I downloaded the ovpn file into my downloads in my kali linux virtual machine.
I opened a terminal in the downloads directory and ran the command
sudo openvpn https-traffic-sniffing.ovpn
I receive a box for password for kali; so I ran the password through, but received this error:
Options Error: Unrecognized option or missing or extra parameter(s) in https-traffic-sniffing.ovpn:1 None(2.5.1)
I’m new to using linux/virtual machine and my experience with open vpn’s is rudimentary at best, so apologies for asking for help with the first problem that arises.
Just to confirm: you did input both auth username and password, correct?
First prompt is the auth username (censored with a black box in the screenshot)
Second prompt is for the auth password (second field in the screenshot)
Do you mean the root password prompt?
If so, enter your root password - openvpn creates a new network interface which usually needs root permissions
with vpnusername and vpnpassword from the lab page (see X0RW3LL’s comment) try:
echo "<vpnusername>\n<vpnpassword>" > creds.login
sudo openvpn --config your.ovpn --auth-user-pass creds.login
The first password prompt is the password to your kali system not the Ovpn, when you input your kali OS password, then it asks for OVPN username and password which is provided
I think non of above answer to the question. I have the same problem. After I enter the command "sudo openvpn https-traffic-sniffing.ovpn " I’m directly asked to enter the kali root password which is normal for sudo. But then I get the error message : “Options error: Unrecognized option or missing or extra parameter(s) in https-traffic-sniffing.ovpn:1: None (2.5.1)” so I’m even not able to enter username/password credentials for openvpn.
When I cat https-traffic-sniffing.ovpn I see that all what is inside the file is a word “None”. So I think there is a problem in a Lab while downloading VPN file. Could you confirm, please?
I restarted the Lab and downloaded the file again. It’s ok now
