With SSH you can create trust relationships between machines to connect between them without asking for password to be able to install Veritas software or just to connect quickly to remote systems.
First, you must create the Secret and Public key with this command:
# ssh-keygen -t dsa -f $HOME/.ssh/id_dsa -P ''
You can choose dsa or rsa as type of ssh protocol version (should use the same as on sshd_config file).
rsa is used with protocol 1 in ssh.
dsa is used with protocol 2 in ssh.

Configure vsftpd with SSL
.- Check that we have vsftpd compiled with SSL support
# ldd /usr/sbin/vsftpd | grep ssl
libssl.so.5 => /lib/libssl.so.X
.- Create a cert
# openssl req -x509 -nodes -days 730 -newkey rsa:1024 -keyout /etc/ssl/certs/vsftpd.pem -out /etc/ssl/certs/vsftpd.pem
.- Add on vsftpd.conf the following line
[...]
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=NO
force_local_logins_ssl=YES
ssl_tlsv1=YES
ssl_sslv2=NO
ssl_sslv3=NO
rsa_cert_file=/etc/ssl/certs/vsftpd.pem

#When you forget root password, there is a way to set a new password accessing the console after booting or restarting the system.
When grub load, edit the line kernel and add in the end of kernel parameters:
init=/bin/bash
The system will go up without requesting root password like in single user.
After the system is up, re-mount / filesystem
# mount -o remount,rw /
Now the / filesystem is accesible and you can change root password with:
# passwd root
Now reboot the machine Read more...
Running ipconfig shows this error:

Now ipconfig should work correctly.
When the virtual machine requires a high-speed timer, the requirement is
usually met by /dev/rtc on the host. In some circumstances, /dev/rtc is
unavailable, leading to slowness in the guest.
The main symptom is that the virtual machine's clock fails to keep time
properly. In addition, applications that are timed by the virtual machine's
clock, such as Windows menu animations, may also run slowly. Applications that
don't use the timer to delay their execution run at normal speed.
