7.6.5 Setting up and using SSH
You can use remote access to access devices from the PCU.
An SSH environment is preinstalled when the PCU base software for Windows 7 is installed.
You can log on with PuTTy.
You can use an SSH key to log on. A script for setting up the infrastructure on devices is
provided. However, for security reasons no previously generated keys have been stored.
Setting up remote access with SSH and key pair
The procedure for setting up users and using remote access is the same as the usual procedure
