Troubleshooting tips

If you are not seeing any output from the ftpwho command, it is possible that there are no current FTP sessions. You can try connecting to the server via FTP to create a session and then run the ftpwho command again.

If you are having trouble terminating a specific FTP session using the kill command, make sure that you are using the correct process ID (PID) for the FTP session. You can use the ftpwho command to find the PID for the session you want to terminate.
