ftpwho

Display current FTP server session details.

ftpserverconnectionsusersstatus

Additional Notes

ftpwho shows detailed information about currently connected FTP sessions on a ProFTPD server. Unlike ftptop's continuous display, ftpwho prints a single snapshot of active connections and exits.

The output typically includes the process ID, username, remote IP address, connection duration, and current transfer status for each session. It also shows a summary line with the total number of connected users.

Parameters

  • options: Flags that change how ftpwho behaves.
  • target: Optional file, device, interface, user, service, or command target when the command supports one.

Common Options

  • -p port: Use the specified port for the status connection.

Practical Notes

  • ftpwho is specific to ProFTPD and requires the mod_status module.
  • For a continuously updating view, use ftptop instead.
  • The command is useful for quick checks of who is connected and what they are transferring.
  • If the output is empty or shows an error, verify that ProFTPD is running and has status reporting enabled.
