FTP实验报告 实验背景： 实验步骤： 第一步：搭建环境 [root@redhat ~]# mount /dev/cdrom /mnt //挂载光盘到/mnt目录下 mount: block device /dev/cdrom is write-protected, mounting read-only [root@redhat ~]# cd /mnt/Server/ .//切换目录 [root@redhat Server]# rpm -ivh vsftpd-2.0.5-10.el5.i386.rpm //安装vsftpd软件包 warning: vsftpd-2.0.5-10.el5.i386.rpm: Header V3 DSA signature: NOKEY, key IDPreparing... ########################################### [100%] 1:vsftpd ########################################### [100%] [root@redhat Server]# useradd user1 //创建user1系统账号 [root@redhat Server]# useradd user2 //创建user2系统账号 [root@redhat Server]# passwd user1 //给user1设置密码abc Changing password for user user1. New UNIX password: BAD PASSWORD: it is WAY too short Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@redhat Server]# passwd user2 //给user2设置密码abc Changing password for user user2. New UNIX password: BAD PASSWORD: it is WAY too short Retype new UNIX password: passwd: all authentication tokens updated successfully. ftp服务器搭建完成后开启端口、启动就能使用，但很危险，情况如下： C:\Documents and Settings\studentftp //命令行登陆ftp Connected to . 220 (vsFTPd 2.0.5) User (:(none)): user1 //用user1登陆 331 Please specify the password.

Consider using PASV. 150 Opening BINARY mode data connection for /etc/passwd (1599 bytes). 226 File send OK. ftp: 收到 1599 字节，用时 0.00Seconds 1599000.00Kbytes/sec. 注释：这样很危
