Guide for configuring netLD to use a jumphost.
Overview
When netLD (or a SmartBridge) cannot be installed in a network that has direct, routable access to devices, netLD can be configured to perform operations by going through an intermediate jumphost. This jumphost can be a Linux or Cisco IOS device that is routable from netLD and also has access to SSH or Telnet on the target devices.
Note: When using a jumphost, only SSH and Telnet are supported. Operations cannot be performed that require other protocols such as SNMP, FTP or TFTP because these protocols would require direct access back to the netLD server.
This feature was added in netLD version 16.
Setup
NetLD can be configured to perform backups against device through an intermediate jumphost from the Networks page of the Server Settings dialog.
When the "Use a jumphost for this network" checkbox is checked, all operations against devices within the given managed network will be performed using the specified jumphost.
| Field | Description |
| IP Address | The IP address of the host that will act as the jumphost. |
| Username | The username of the user on the jumphost. This is used when connecting to the jumphost over SSH. |
| Password | The password for the jumphost user. |
| Adapter | The device type of the jumphost. This selection tells netLD which adapter to use to perform the connect to the jumphost itself. |
When both a SmartBridge and a jumphost are configured for a network, the SmartBridge will initiate connections to the jumphost when operations are performed. The connection will look something like this: NetLD -> SmartBridge -> Jumphost -> Device.
