说明&＃xff1a;学生作业&＃xff08;个人经验仅供参考&＃xff09;&＃xff1a;
1. Windows下虚拟机Ubuntu 14.04 搭架vsftp
1.1 查看虚拟机与本机是否能ping通
这里虚拟机和本机网络的连接方式是桥接模式。首先通过ipconfig&＃xff08;windows&＃xff09;、ifconfig&＃xff08;ubuntu&＃xff09;得到机子的ip地址&＃xff0c;然后查看是否能够pingt通
windows ping ubuntu
ubuntu ping windows
有些情况下windows能够ping通ubuntu&＃xff0c;但是ubuntu ping不通windows&＃xff0c;可能是windows的防火墙设置有问题&＃xff0c;我找到的解决办法是
允许选中框中的条目
1.2 ubuntu搭建vsftp
在ubuntu上安装vsftp&＃xff0c;后面的d代表的是这个程序会在开机的时候就启动直到关机
sudo apt-get install vsftpd
编辑vsftp的配置文件&＃xff0c;保险起见在配置之前先将配置文件备份
cp etc/vsftpd.conf /home/xxx/Desktop/vsdtpd.conf.back
sudo vim vsftpd.conf
之后配置vsftp&＃xff0c;这是最关键的部分&＃xff0c;配置稍微有问题就会出错
#禁止匿名访问
anonymous_enable&＃61;NO
#接受本地用户
local_enable&＃61;YES
#允许上传
write_enable&＃61;YES
#用户只能访问限制的目录
chroot_local_user&＃61;YES
#设置固定目录&＃xff0c;在结尾添加。如果不添加这一行&＃xff0c;各用户对应自己的目录&＃xff0c;当然这个文件夹自己建
local_root&＃61;/home/ftp
重启ftp
sudo service vsftpd restart
添加ftp用户名和密码 /home/ftp为我设置的ftp目录&＃xff0c;目录设置不一样会530错误&＃43;_&＃43;||
源自&＃xff1a;http://blog.sina.com.cn/s/blog_7880d3350102vvlb.html
sudo useradd -d /home/ftp -M ftp
sudo password ftp参考&＃xff1a;

2. Winform下对FTP操作
这里附上我使用的ftp操作类&＃xff0c;我这里使用递归将FTP目录下的文件和文件名显示在c# treeview中
FTP操作的我是在http://www.cnblogs.com/swtseaman/archive/2011/03/29/1998611.html找的&＃xff0c;但是根据项目修改了部分
