Turn off unneccessary unix processes - on linux/unix systems run chkconfig
bash$ su - root
bash# man chkconfig
bash# chkconfig --help
bash# chkconfig --list | grep on | less
From the above list, turn off the processes you do not want to start automatically -
bash# chkconfig --level 0123456 <service name> off
Next time when the machine is booted these services will not be started.
Now, shutdown the services manually which you just turning off.
bash# cd /etc/rc.d/init.d
bash# ./<service name> stop
Do not run any other application processes which are unnecessary.
Do not leave X-Window running unattended. Because X-window processes
consume memory, CPU load and can be a serious security hole from outside attacks.
The X-window managers generally used are KDE, GNOME, CDE, XDM and others.
You must exit the X-window immediately after using and most of the time
you should see command line console login prompt on the CVS server machine.
