scp: Connection closed-O Use the legacy SCP protocol for file transfers instead of the SFTP protocol. Forcing the use of the
SCP protocol may be necessary for servers that do not implement SFTP, for backwards-compatibility for
particular filename wildcard patterns and for expanding paths with a ‘~’ prefix for older SFTP
servers.
