linux as4 ftp如何禁止匿名登录

默认配置vsftpd 是允许匿名登录的，也许不安全，那么如何禁止不输入密码就登录？

1.vi /etc/vsftpd/vsftpd.conf

把

anonymous_enable=YES 修改为anonymous_enable=NO

 

注意，如果改为#anonymous_enable=YES 还是允许匿名登录的

2. 重新启动VSFTPD

[root@localhost vsftpd]# service vsftpd restart
Shutting down vsftpd: [  OK  ]
Starting vsftpd for vsftpd: [  OK  ]

3.[root@localhost vsftpd]# ftp localhost
