Secure notebook with htaccess?
we installed sage-5.9 on a server (Ubuntu 12.04) of our working group. We would like to open the port, such that all members of the team can access the notebook without a ssh tunnel. Is it possible to secure the access with htaccess or something like that?
Or to ask it in an other direction: Is a notebook secure enough without restricting the access? The users are not allowed to create new users. But could this be a security issue for our server?
