Install a Linux agent
Before you can use N-able N-central to monitor and manage computers at a customer's site, you need to install the agent. The Linux agent monitors local services and reports any issues. Linux agents are installed by downloading and running the compressed installation files. Linux installs require independent Agents for 32-bit and 64-bit OS installs.
There are customer-specific and generic system installers.
The customer-specific installers are pre-configured with activation keys, registration token, customer names, and IP address of your N-able N-central server. As the customer-specific installers are very easy to use, we recommend that you make them your first choice when downloading the agent or probe software.
Generic system installers require you to specify either the activation key, or the IP address of your N-able N-central server and a customer name or customer ID. These installers are useful when you want to keep a copy of a certain version of the agent or probe offline.
The probe performs an SSH connection a Linux device. To discover a Ubuntu/Debian OS device, the device must have openssh installed.
For troubleshooting installation issues, see the N-able Success Center Knowledge Base.
The Linux agent supports the following operating systems:
Independent Agents are required for 64-bit Linux OS installations.
The probe performs an SSH connection to a Linux device. To discover a Linux OS device, the device must have openssh installed.

Ubuntu 22.04 LTS (64-bit)
