The FEAT and CLNT commands

WS_FTP sends the FEAT command to the FTP server when you connect to a site. When an FTP client sends the FEAT command, the server is expected to reply with the features that it supports (such as integrity checking, hashing, and resume transfer).

The CLNT command, if it appears in the FEAT list returned by the FTP server, causes the FTP client to send its name and version number: “CLNT WS_FTP_Professional 12.4” (or WS_FTP_LE).

You can disable the FEAT command to handle the case when a firewall does not allow the FEAT command and disconnects when the command is received.

To disable the command:

  1. In the tool bar, click Connect (or select Connections > Site Manager) to open the Site Manager.
  2. Select a remote site and click Edit. The Site Options dialog appears.
  3. In the left pane, select Startup.
  4. Select the Disable the FEAT command option.
