Guidance on Pixhawk 5x Eth port

Hello All,
First time posting here, so if I missed something in the onboarding class I apologize.

Looking for any guidance / tricks / documentation on abilities of the Ethernet Port on the Pixhawk 5x.

I can see that port 23 is open, and when trying to access via telnet I get an Admin / Password prompt for NuttShell (NSH). I’ve looked for those credentials but can’t seem to locate them, or any documentation on capabilities.

Thank you all!

Well I’m dumb:
