Welcome to the Oxidized help section.
You are free to ask any questions surrounding Oxidized, it does not need to be specific to LibreNMS integration.
Hello all. Thank you in advance for your assistance. It is greatly appreciated.
I am very new to LibreNMS/Oxidized and in an effort to utilize config backup/diff more immediately I’m attempting a standalone implementation of Oxidized. At this stage I have completed an Oxidized build and am trying to gather the backup from a single device.
I am receiving an SSH error that I am unable to remedy and am hoping you can assist.
*** The device is a Cisco CSR8kV. From the Oxidized server I am able to SSH directly to the CSR manually. When I attempt it via Oxidized I receive the following debug after which the job repeats:
