Overview

The 

Unable to show "metadata-from": No such page "_space_variables"
is enhanced with a new utility /opt/sonus/bin/SbcSftp with permissions -rwsr-xr-x, which allows the
Unable to show "metadata-from": No such page "_space_variables"
user to securely transfer files to a remote server using the Linux shell. 

When executed, the program SbcSftp:

  • Creates the necessary Access Control List (ACL) to allow the sftp connection from the
    Unable to show "metadata-from": No such page "_space_variables"
    linux shell to a remote server

  • Uploads/Downloads specified files to/from the remote server over a SFTP session, if the user has permissions to access the file

  • Deletes the ACL

The advantage of using SbcSftp over vanilla sftp is that SbcSftp automatically creates and deletes ACLs for accessing the remote server.

Message logs

The file /var/log/sftp.log contains messages about the following:

  • The success/failure of file transfers using SbcSftp, along with exit codes

    Note

    The exit codes are identical to the GNU Linux sftp utility - 0 for success, and 1 for failure.

  • The destination for successful uploads/downloads

Command Syntax

Warning

Customers are advised to use the following "nohup" command so that it completes in the background in case the SSH session closes unexpectedly. This helps to ensure that the ACL rules are cleaned up correctly.

% nohup /opt/sonus/bin/SbcSftp <remote_IP> <remote_port> <username> [upload | download] <local_SBC_path> <remote_server_path>

To use the SbcSftp program, execute the following command:

% /opt/sonus/bin/SbcSftp <remote_IP> <remote_port> <username> [upload | download] <local_SBC_path> <remote_server_path>
Tip

Enclose wildcard expressions in file paths within double quotes (""). For example:

  • <"local_SBC_path">
  • <"remote_server_path">
Caution

Do not configure ACLs to the same remote IP and port using both

CLI and the SbcSftp command; otherwise it causes the SbcSftp command to fail.
