 This section provides the information on how to upload application and license files to SBC.

File Upload

The File Upload tool allows you to upload application files to SBC. These files must be available in your local drive for easy access and faster upload. You can upload the following files:

  • SBC Application Files (.tar.gz, .md5, .qcow2 and .signature files): Specifies the SBC Application files. These are used to upgrade or to perform a fresh SBC installation.

    Note

    The SBC does not support .qcow2.md5 files for EMA upload, for an upgrade, or installation.

  • SBC Configuration Files (.template and .cli): Specifies the SBC configuration files.
  • SBC Back-up Files (.tar.gz): Specifies the back-up files which can be uploaded to SBC from an external source.
  • License Files (.pem, .xml, and .p12 files): Specifies the list of SBC Licenses.
  • Announcement Files (.wav files): Specifies short audio files used when SBC sends the 183 Session Progress in SIP call.

  • Certificate Files (.der files): Files with .der extension are digital certificate files created in the Distinguished Encoding Rules (DER) format. It contains a binary representation of the certificate, and is commonly used for storing X.509v3 certificates in public key cryptography.

    Note

    The SBC allows you to upload only the allowed filed types, and also places restrictions on the file names. Such measures are implemented to secure the SBC from malicious file uploads. To know more about the allowed file types and file name restrictions, see the Restrictions on File Properties section.

    Note

    To know more about uploading announcement files, refer to System Administration - Manage Announcements

On SBC main screen, go to Administration > System Administration > File Upload. The File Upload screen is displayed.

Figure : File Upload Screen

The File Upload screen consists of the following panes:

  • Upload Queue: This pane allows you to add files from your desired location and upload the same to SBC.
  • Files on SBC: This pane lists all the recently uploaded files to SBC with the size of each file.
  • Software Packages on SBC: This pane lists the currently installed/available SBC package along with the size of the package.

By default, only ten entries are displayed in all the panes. You can choose the number of files to view under the Show entries drop-down box.

To Add and Upload Files on the SBC

  4. Click Upload All Files to upload the all files from the Upload Queue list to the SBC.

    Warning

    Do not close the screen or browser until the file upload is complete. Similarly, if you perform any other operations on the EMA, this will abort the file upload.

    Note

    To abort the uploading process, click the Delete icon against the file which you want to remove. The file uploading process stops.

Restrictions on File Properties

The File Upload window in the EMA navigation path Admistration > System Administration > File Upload is enhanced to accept files with very specific properties. This enhancement removes the vulnerability of the SBC and the associated network against uploading and executing malicious files. Upload the files with the following properties:

  • Files with the following extensions, provided they simultaneously satisfy the other criteria mentioned in this bullet list:
    • xml
    • wav
    • template
    • cli
    • pem
    • p12
    • md5
    • signature
    • qcow2
    • tar.gz
    • der
  • The length of the filename is less than or equal to 100 characters.
  • The filename does not start with the "." (period) character.
  • The filename matches with certain accepted patterns, as defined in a regular expression implemented internally.


Note

Even if a malicious executable file is bundled in a tar.gz file with an acceptable file name/properties and is uploaded, the SBC does not executes such files due to mismatch in the md5 checksum of the uploaded file and the corresponding genuine version. 

Note

Do not use multiple dots (".") in the filenames that you upload. The only dots allowed are the ones used for filename extension.

For example, sbc-1.2.3-package.tar.gz is not allowed, but sbc-1_2_3-package.tar.gz is allowed.

This rule applies only for files that you customize and upload to the SBC. However, this rule does not apply to the following files provided by Sonus (filenames provided are only for illustration, and the actual filenames may vary based on the release version):

  • sbc-V06.02.00-R000.x86_64.md5
  • sbc-V06.02.00-R000.x86_64.signature
  • sbc-V06.02.00-R000.x86_64.tar.gz
  • sbc-V06.02.00R000-connexip-os_05.00.00-R000_1_amd64.qcow2

 

Examples

Given below are some examples of allowed and disallowed attempts of file uploads:

  • File with one of the several acceptable extensions:

  • File with an unacceptable extension:

    Figure : Example - Disallowed File Extension

  • Length of filename exceeds 100 characters:

    Figure : Example - Fiole Name Exceeding 100 Characters

  • Filename starts with ".":

    Figure : Example - File Name starts with "."

  • Filename does not match accepted pattern:

To Add and Upload SBC Application Back-up Files on the SBC

    • config_<System_Name>_<File_Name>, and should end with .tar.gz

    or

    • auto_backup_config_<System_Name>_<File_Name>, and should end with .tar.gz

    For example, config_SBC001_BackupFile1.tar.gz or auto_backup_config_SBC001_BackupFile1.tar.gz.

  3. Click Upload All Files to upload all the files listed in the Upload Queue panel to SBC.
