1. view and start vsftpd run # ntsysv check whether vsftpd is available. If yes, select and install vsftpd if no vsftpd is available. start ftp. # service vsftpd restart 2. configure the vsftpd user and enable the root user. # cd/etc/vsftpd www.2cto.com # vi ftpusers comment out "root". some people say they need to modify the user_list file # vi user_list comment out "root". I still cannot log on successfully after following the above steps, so I searched for the answer online and finally found out how to solve it. You also need to execute # iptables-I INPUT-p tcp -- dport 21-j ACCEPT, which may be a problem with my iptables module, so you need to execute the above command.
