In SuSE, you can determine the status of VSFTPD process is running or not by using the netstat -a command, which lists all the TCP and UDP ports on which the server is listening for traffic. Execute below command to check the status:
# netstat -a | grep ftp tcp 0 0 *:ftp *:* LISTEN
Output above means the VSFTPD is running. But, if no output coming out after the command execution, it means the VSFTPD is not running.
