Is it possible to only have 1 user signed in at a time or only allow..

[adamrau]

RedHat 7.1

1) Can i have only one user signed in at a time? If so, how?
I dont want multiple users signed in.

2) Can I setup my system to only allow signin via console, not from anywhere else? If so, How?
I only want console access which means the only person that can log onto my system, is the person PHYSICALLY using it.

Thanks and sorry if my questions are a little out of the ordinary.

Much thanks in advance
Adam

You can control user login access with the /etc/login.access file. The file consists of entries listing users, whether they are allowed access, and from where they can access the system. A record in this file consists of three colon-delimited fields: a plus (+) or minus (-) indicating whether users are allowed access, user login names allowed access, and the remote system (host) or terminal (tty device) from which they are trying to login. Other access control files are used to control access for specific services i.e., /etc/hosts.deny, /etc/hosts.allow.

Hope this helps.

The software required `Windows 95 or better', so I installed Linux.

Hi,

On redhat you can use the pam_access module configuration file, i.e. :

/etc/security/access.conf

You would need to configure that file (see examples inside) and also add a line to /etc/pam.d/login so that the pam_access module is called :

account required /lib/security/pam_access.so

Hope this helps
