    Considerations When Adding an FTP or SFTP Server

    FTP or SFTP servers are used for network element database backup and restore functions, and network element system software upgrades. The PSM server installation includes a local (S)FTP server that is compatible with PSM and BTI Series network elements.

    You may choose to use an external (S)FTP server. The following third party (S)FTP servers have been verified to be compatible with PSM and BTI Series network elements:

    • FileZilla FTP server
    • WinSSHD server
    • VSFTPD server
    • Cerberus FTP server

    Note: Some free open source (S)FTP servers may not work properly due to incompatibilities with PSM and BTI Series network elements. For best results, choose a server from the list above.

    Note: To use SFTP, the OpenSSH environment must be configured on the machine on which the PSM client is installed, and shell access must be enabled on the machine where the SFTP server is installed.

    Updating the List Of Known Hosts on the PSM Server Machine

    Use the following procedure to add the (S)FTP server to the list of known hosts on the PSM server machine.

    Note: You must perform this procedure even if you are using the included PSM (S)FTP server. The included PSM (S)FTP server is not added to the list of known hosts by default. It must be explicitly added.

    1. At the command line on the PSM server machine, enter the following command:
      ssh <username>@<hostname> 

      where hostname is the IP address of the (S)FTP server and username is the username to connect with.

      The systems responds with:

      The authenticity of host 'hostname (hostname)' can't be established. DSA key fingerprint is xxxxxx. Are you sure you want to continue connecting (yes/no)?

    2. Enter yes.

      The systems responds with:

      Warning: Permanently added 'hostname' (DSA) to the list of known hosts.

    3. Log off of the (S)FTP server by typing exit at the command prompt.

      You have successfully completed this procedure.
