Dear userix, I have a server with lots of students accounts, and some professors and admins. I wonder, what would be an easy way to freeze students access now, stopping them from logging via SSH, and reinstating them on February? They are part of a "group" if that helps. Thanks, Beco -- Dr Beco A.I. researcher "My psychiatrist told me I was crazy. I told him I wanted a second opinion. He told me that I was also ugly."
