apt-get update

apt-get install -y auditd

# delete the line pam_tty_audit.so
sed -i '/pam_tty_audit.so/d' /etc/pam.d/sshd

# add this line to the bottom of the file
echo 'session required pam_tty_audit.so enable=*' >> /etc/pam.d/sshd

# add a couple more required lines:
echo '-a exit,always -F arch=b64 -F euid=0 -S execve' >> /etc/audit/audit.rules
echo '-a exit,always -F arch=b32 -F euid=0 -S execve' >> /etc/audit/audit.rules
