Subject: Re: John the Ripper in the cloud update 2023/02

hi. I am really a noob in aws. I loved this idea and try to run it.

I configure it with the default configuration and when I will run, I get
this error:

You have requested more vCPU capacity than your current vCPU limit of 0
allows for the instance bucket that the specified instance type belongs to.
Please visit to request an
adjustment to this limit.

So... What do I do with this? I read this link
<> but I
have no idea if it will work or not. Is it just me or everyone is having
this problem?
