Description:
-
Autologoff is a set of
administrative tools for Linux terminal setup and other server/client
setups in Linux (e.g. Ssh, telnet) .With this, the administrator can
control the amount of time a user avails the facility in the terminal
server client setup.
-
In Autologoff version
1.0 the
administrator has authority to change the time that is alloted to the
user to avail the facility .
-
In autologoff version
2.0, the
administrator has authority to eject users at will.
A
brief summary of the
problem
Information Technology centre at Takshashila campus, Devi Ahilya Vishwavidyalaya, Indore
has the following setup for
Internet browsing
Server-
CPU - INTEL 2.2 G Hz Xeon processor
RAM- 1.5 Giga bytes
Clients
IBM thin clients 45 Nos
VXL terminals 45 Nos
The IBM thin clients use windows IBM station manager to load the
kernel via NFS from the server.
The VXL terminals use their inbuilt kernel.
After the bootup procedure , the machines log in to the server
using XDMCP and use the kernel and the display from the server running
LINUX Mandrake 10.0
Problems
faced
Previously this whole setup based was on windows
terminal client/server setup , where there were tools like task manager
to administrate the above setup, but after migrating to LINUX platform
due to license issues the organization was finding it difficult to
administer the entire setup, since the setup at the Information
technology centre comprises of power Pcs which load the windows
terminals server kernel from the server and then the display is
transferrred from the server running Linux Mandrake . So, the problems
stated were
1.) Free the system resources used by a user after he has left without
Logging out (since the terminal server does not free the memory, disk
Resources used by the user until he has properly logged out)
2.) Control the time a user avails the facility (i.e. allow the users
to use the Browsing facility for a specific duration of time)
3.) Remove users who have exceeded the allotted time.
With the above problems it leads to
a.) Unnecessary load on the server, which make the systems slow.
b.) Bandwidth wastage.
