Fault in Logging in to the FTP Server

Cause Analysis
  • The FTP server is not running.
  • The listening port number of the FTP server is not the default one, and no port number is specified when you log in to the FTP server.
  • The authentication information, authorized directory, and user level of the FTP user are not configured.
  • The number of online FTP users who have logged in to the FTP server reaches the upper threshold.
  • An ACL is configured on the FTP server, and the FTP client IP address is not specified in the ACL.

Procedure

  1. Check whether the FTP server is running properly.

    Run the display ftp-server command in any view to check the FTP server status.

    • The following information indicates that the FTP server is not running:
      <Huawei> display ftp-server
      Info: The FTP server is already disabled
      Run the ftp server enable command in the system view to start the FTP server.
      <Huawei> system-view
      [Huawei] ftp server enable
      Warning: FTP is not a secure protocol, and it is recommended to use SFTP.       
      Info: Succeeded in starting the FTP server
    • The following information indicates that the FTP server is running properly:
      <Huawei> display ftp-server
         FTP server is running 
         Max user number                 15
         User count                      0
         Timeout value(in minute)        30
         Listening port                  21
         Acl number                      0
         FTP server's source address     0.0.0.0

  2. Check whether the listening port number of the FTP server is the default port number 21.

    1. Run the display tcp status command in any view to check the current TCP port listening status.

      <Huawei> display tcp status
      TCPCB     Tid/Soid Local Add:port         Foreign Add:port       VPNID  State
      2a67f47c  6  /1    0.0.0.0:21            0.0.0.0:0              23553  Listening

    2. Run the display ftp-server command in any view to check the listening port number of the FTP server.

      <Huawei> display ftp-server
         FTP server is running 
         Max user number                 15
         User count                      0
         Timeout value(in minute)        30
         Listening port              21
         Acl number                      0
         FTP server's source address     0.0.0.0

    If the listening port number is not 21, run the ftp server port command to set the listening port number to 21.

    <Huawei> system-view
    [Huawei] undo ftp server
    Info: Succeeded in closing the FTP server.
    [Huawei] ftp server port 21
    [Huawei] ftp server enable
    Warning: FTP is not a secure protocol, and it is recommended to use SFTP.
    Info: Succeeded in starting the FTP server

    Alternatively, enter the port number configured on the server when you set up an FTP connection on the FTP client.

  3. Check whether the authentication information, authorized directory, and user level of the FTP user are correctly configured.

    The FTP user name, password, authorized directory, and user level must be configured. If the FTP authorized directory and user level are not configured, login fails.

    1. Run the aaa command to enter the AAA view.
    2. Run the local-user user-name password irreversible-cipher password command to configure the local FTP user name and password.
    3. Run the local-user user-name ftp-directory directory command to specify an FTP authorized directory for the FTP user.
    4. Run the local-user user-name privilege level level command to set the FTP user level. The user level must be set to 3 or upper levels to ensure successful connection establishment.

    The service type is optional. By default, the system supports all service types. If you set the service-type parameter, only the service types that you set are available to FTP user.

    Run the local-user user-name service-type ftp command to set the service types for the FTP user.

  4. Check whether the number of online FTP users who have logged in to the FTP server reaches the upper threshold (15).

    Run the display ftp-users command to check the number of online FTP users.

  5. Check the ACL rule on the FTP server.

    Run the display ftp-server command to check the ACL rule on the FTP server.

    If an ACL is configured on the FTP server, only IP addresses specified in the ACL can log in to the FTP server.

Failure in Uploading Files to the FTP Server

Cause Analysis
  • The FTP source or destination directory name consists of unsupported characters.
  • Space of the FTP root directory is insufficient.

Procedure

  1. Check whether the FTP source and destination directory names consist of unsupported characters.

    The following characters and spaces are forbidden: ~ */ \ : ' "

    If the directory names consist of any unsupported characters, modify the directory names.

  2. Check whether space of the FTP root directory is insufficient.

    Run the dir command on the FTP server to check the free space of the FTP root directory.

    If the space of the FTP root directory is insufficient, run the delete /unreserved command in the user view to delete unnecessary files.
