• 查看端口和配置IP命令

  [root@room9pc01 bin]# netstat -anptu

• FTP主配置文件

[root@room9pc01 bin]# ls /etc/vsftpd/vsftpd.conf               #查看FTP端口主配置文件
 /etc/vsftpd/vsftpd.conf
   
[root@room9pc01 bin]# netstat -anptu |grep vsftpd                 #查看FTP端口开放的IP
tcp        0      0 0.0.0.0:21              0.0.0.0:*               LISTEN      1396/vsftpd
