Unable to connect to RedPitaya via SSH

[gregofuente]

Apologies if this is a simple question--I'm new to RedPitaya. My RedPitaya doesn't have the default username and password, so I made the appropriate changes in global_config.yml. I then tried to initialize a RedPitaya object using the following line of code: >>> p = Pyrpl('global_config') Even though I was able to connect to the RedPitaya successfully after these changes, I got a new error:

What can I do to address this? I'm using version 0.9.5.0.
