Service Credentials

Default log-in credentials for emonPi/emonBase running latest emonSD based SD card.

SSH

To connect to emonPi / emonBase via ssh:

• If running emonSD-30Oct18 or newer SSH is disabled by default
• SSH can be enabled by either:
  • Creating a file called ssh in the FAT /boot partion on the SD card. This can be done externally using a card reader + PC or using a USB keyboard + HDMI screen to login to the Pi and create the ssh file: sudo touch /boot/ssh. Then reboot sudo reboot
  • Or selecting the SSH Enable LCD menu item then pressing and holding the emonPi LCD push-button:

Once enabled, SSH can be disabled in the same way:

• Linux / Mac : open terminal window $ ssh [email protected] or $ ssh [email protected]<IP ADDRESS>
• Windows: use Putty application
• Google search ‘Raspberry Pi SSH’ for many tutorials, Adafruit has a good guide.

Once logged in change password with:

If you see the error: Authentication token manipulation error when changing password, first mount the filesystem as read-write using $rpi-rw.

If you wish to disable SSH run:
