Scenario 16 – Appending to a File in the FTP
Server
This scenario describes how to send a file to the FTP server:
• With Automatic Authentication enabled by specifying all authentication details: IP address of the device, valid
login name, valid password, and valid account password.
• Data connection in ACTIVE mode.
• If an entry for the default file name does exist in the configuration, the user is not prompted for the file name.
If the directory is also configured using set command, the directory-name is appended to the filename. The
same is true for file size too (<directory-name/file-name> may be the path name with respect to the ftp root).
Note: If either filename or filesize are not configured, IP module prompts for that parameter.
Description
The IP module establishes a control connection, automatically checks for the configured
values and logs into the FTP server. If successfully logged in, it sends a message and
prompts for data as shown here:
Connected
Enter data. Enter Ctrl+CDZ with 3 seconds delay to abort session
------ File Transfer ----
To abort FTP session: Hold down the Ctrl key and type letters CDZ all in row with no spaces.
When the specified filesize is reached, the FTP session responds with the OK message.
By default the data connection is in active mode. The client sets the data transfer mode as
‘BINARY/IMAGE’ during the file transfer.
If the –m option is specified, it prompts the user for the next transaction or to quit. If the user
selects to do another transaction, then he is prompted to enter the Filename again. In this
case, the filename entered for the previous transaction will not be considered. The user
should specify the whole path. The directory specified using “Set ftp directory xxx” or the
filename specified using “set ftp filename xxx” or filesize specified using “set ftp filesize xxx”
will not be considered.
Note: If '-p' is specified in the command, the data connection will be in passive mode.
