===== SSH connection on STKa8XxS =====

<WRAP round important>Please keep in mind that the following instructions focus on simplicity, not on security.</WRAP> 

<WRAP round info>For the sake of simplicity password authentification can be used for SSH.</WRAP>

=== Setup Yocto build environment ===

The OpenSSH sftp server is not installed into the image by default, add the following to your local.conf to install it.

<code>IMAGE_INSTALL_append = “openssh-sftp-server”</code>


=== Setup on Target ===

To setup a password for the default user root, 
execute the command **passwd root** and set your password.

=== Modify SSH configuration ===

Uncomment the following options in **/etc/ssh/sshd_config** to allow that the user root can authenticate 
with a password on the STKa8XxS.

<code>PermitRootLogin yes
PasswordAuthentication yes
</code>
