Configuring SSH Host Keys for Secure Copy

Secure Shell (SSH) uses encryption algorithms to generate a host, server, and session key system that ensures secure data transfer. You can configure SSH host keys to support secure copy (SCP) as an alternative to FTP for the background transfer of data such as configuration archives and event logs. To configure SSH support for SCP, you must complete the following tasks:

• Specify SSH known hosts by including hostnames and host key information in the Routing Engine configuration hierarchy.
• Set an SCP URL to specify the host from which to receive data. Setting this attribute automatically retrieves SSH host key information from the SCP server.
  • Verify that the host key is authentic.
  • Accept the secure connection. Accepting this connection automatically stores host key information in the local host key database. Storing host key information in the configuration hierarchy automates the secure handshake and allows background data transfer using SCP.

This section contains the following topics:

• Configuring SSH Known Hosts
• Configuring Support for SCP File Transfer
• Updating SSH Host Key Information
