Disabling All Console Access

The PAM pam_console.so module manages console file permissions and authentication. (See the Official Red Hat Linux Reference Guide for more information on configuring PAM.) If you want to disable all console access, including program and file access, comment out all lines that refer to pam_console.so in the /etc/pam.d directory. As root, the following script will do the trick:

cd /etc/pam.d
for i in * ; do
sed '/[^#].*pam_console.so/s/^/#/' < $i > foo && mv foo $i
