Configuring Support for SCP File Transfer

To configure a known host to support background SCP file transfers, include the archive-sites statement at the [edit system archival configuration] hierarchy level.



[edit system archival configuration]

archive-sites {
scp://username<:password>@host<:port>/url-path;
}

Note: When specifying a URL in a JUNOS statement using an IPv6 host address, you must enclose the entire URL in quotation marks (" ") and enclose the IPv6 host address in brackets ([ ]). For example, “scp://username<:password>@[host]<:port>/url-path”;

Setting the archive-sites statement to point to an SCP URL triggers automatic host key retrieval. At this point, the JUNOS system software connects to the SCP host to fetch the SSH public key, displays the host key message digest or fingerprint as output to the console, and terminates the connection to the server.



user@host# set system archival configuration
archive-sites “<scp-url-path>”

The authenticity of host <my-archive-server (<server-ip-address>)> can’t be established.
RSA key fingerprint is <ascii-text key>. Are you sure you want
to continue connecting (yes/no)?

To verify that the host key is authentic, compare this fingerprint with a fingerprint that you obtain from the same host using a trusted source. If the fingerprints are identical, accept the host key by entering yes at the prompt. The host key information is then stored in the Routing Engine configuration and supports background data transfers using SCP.
