Deployment: Connection Tab

Choose the method to invoke client security:

• Explicit: the explicit (active) security is applied. Immediately after establishing connection, the FTP client on your machine sends a command to the server to establish secure control connection through the default FTP port.

• Implicit: the implicit (passive) security is applied. In this case, security is provided automatically upon establishing connection to the server which appoints a separate port for secure connections.

  Note that the Implicit method is considered deprecated, and using it is discouraged.

From this list, set the protection level for the PROT command:

• <default>: the default server policy is applied.

• Clear: raw data is transferred without applying security.

• Private: the Transport Layer Security (TLS) or Secure Sockets Layer (SSL) applied.

For more information, see the articles on TLS, SSL 2.0, and SSL 3.0.

Select this checkbox to set the client on your machine to passive mode, when it connects to the server to inform about being in the passive mode, receives the port number to listen to, and established data connection through the port with the received number. This mode is helpful when your machine is behind a firewall.

When this checkbox is selected:

1. Hidden files and directories are shown in the Remote Host Tool Window.

2. Hidden files and directories are involved in diff and synchronization operations.

The name of a hidden file or directory starts with a dot ..

Use the options in this area to configure the LIST command usage.

• Compatible with old version of listing children: Select this checkbox to ensure compatibility in child file naming with your FTP server.

  This option is helpful if the remote FTP server reports the following error:

  Invalid descendant file name <file name>
  Selecting this option may slow down synchronization with the server.

• Instead of MLSD: Select this checkbox to use the standard LIST command for listing instead of the MLSD command. This lets you avoid problems, for example, failure during upload with the Invalid descendent file name exception if the FTP server supports MLSD and returns cdir.

Select this checkbox to have CLion restrict the number of connections to be supported simultaneously and specify the maximum number of allowed connections in the field.

Use this list to specify the MDTM FTP command calling policy to retrieve the last-modified time of a given file on the remote host.

The available options are:

• Always: select this option to have MDTM called for every file shown in the Remote Host tool window.

• On copy: select this option to have MDTM called in the following cases:

  • To check whether a file is up to date when the Overwrite up-to-date files checkbox in the Options dialog is cleared.

  • To preserve the actual time stamp of a file during download.

• Never: select this option to suppress calling MDTM.

From this list, choose the commands to be sent to the server to reset the timeout and thus preserve the connection.

In this field, specify the encoding that matches the encoding used by your server. Accept the default value if you are not sure that it supports UTF-8 encoding.

Select this checkbox to have CLion restrict the number of connections to be supported simultaneously and specify the maximum number of allowed connections in the field.

In this field, specify how often you want CLion to send commands to the server to reset the timeout and thus preserve the connection.

In this field, specify the encoding that matches the encoding used by your server. Accept the default value if you are not sure that it supports UTF-8 encoding.

To suppress showing the information popup, select the Ignore info messages checkbox.
