SSH Connector

The SSH connector uses the Paramiko library to connect to Linux/Unix hosts over SSH. Unlike a general-purpose SSH client, the connector does not execute arbitrary shell commands. All operations are typed command templates validated before execution.

Credential Fields

Field	Required	Description
Name	Yes	Display name
Hostname	Yes	Target host hostname or IP
Username	Yes	SSH username
Private Key	Yes	SSH private key (PEM format)
Port	No	SSH port (default: 22)

Capabilities

Action	Description
Execute command template	Run a command from the connector's approved template list
Check service status	Query the status of a named systemd service
Tail logs	Retrieve the last N lines from a log file

Freeform shell commands are blocked unconditionally by the safety engine. All permitted operations must be defined as typed templates.

Consider using the Nexplane Agent

For hosts you control, the Nexplane Agent provides a richer set of typed commands, self-registration, and outbound-only connectivity (no inbound SSH port required).
