unable to login to module running Digi Embedded Linux via ssh or ftp

By default there is no root password set (blank password) in modules running Digi Embedded Linux. This will prevent users from being able to login to it using ssh or ftp.

To correct this, please assign a password to the user which needs to connect to the module
Using passwd command change the password for root:
~ # passwd root
Changing password for root
New password:
Bad password: too weak
Retype password:
Password for root changed by root
 
After that you should be able to ssh in to the module with user root and new password with no  issues. 
ssh root@192.168.1.78
The authenticity of host '192.168.1.78 (192.168.1.78)' can't be established.
