I have an Ubuntu Server 20.04 for Minecraft (no GUI). I connect to it via PowerShell and my Linux laptop with the server’s private IP. I would like a little extra security by spoofing or hiding the IP address of my server. I am a bit nervous to test this out as I am brand new to Linux.
A VPN service recommended this tutorial for what I am trying to accomplish.
I get stumped on step 3, particularly the “Note” (–dn “CN=IP address” --san @IP_address --san IP_address ).
First, I run this:
pki --gen --type rsa --size 4096 --outform pem > ~/pki/private/server-key.pem
Then, I run this but change one line:
pki --pub --in ~/pki/private/server-key.pem --type rsa
| pki --issue --lifetime 1825
–dn “CN=server_domain_or_IP” --san server_domain_or_IP
–flag serverAuth --flag ikeIntermediate --outform pem
The line I will replace is “–dn[…]”. Since I am using an IP instead of DNS, I would need to place my device’s private IP here - “CN=IP address” - but I am not sure what the other two san ones are for? Are they random IPs or is it just my device’s IP two more times?
My other questions:
Thanks and regards, Josh
