windows写文件到ubuntu之ftp
1:安装ftp
sudo apt-get install vsftpd
默认的ftp路径在 /srv/ftp
需要设置这个目录的权限:chmod -R 777 *
2:修改配置
/etc/vsftpd.conf 1.配置 # 设定系统本地用户账户登陆ftp local_enable=YES # 使用用户的本地账户目录作为ftp目录 chroot_local_user=YES # 允许用户上传文件 write_enable=YES 修改完成后保存并重启vsftpd sudo /etc/init.d/vsftpd restart 三. 添加ftp使用用户 sudo useradd -d /home/ftp_testuser -m ftp_testuser sudo passwd ftp_testuser 然后就可以用ftp_testuser和设置好的密码进行登陆ftp了 2.vsftpd的环境 1} vsftp安装完成后会生成一个名字是ftp的账户,密码ftp,可以在/etc/passwd中看到,一般来说这时候可以建立一个ftp文件,自己设置的是/home/ftp,最好再把ftp改成777的权限。 2} /etc/vsftpd.conf 主要就是vsftpd的配置文件,相当重要的一个东西。 3} /etc/pam.d/vsftpd 与pam组相关的文件,pam组主要用来进行身份认证和抵御功能,初期没必要太了解这个。 4} /etc/ftpusers 这个主要是和上面的搭配,设定拒绝登陆的账号,一般都是本机上的账号,vim它,会发现root在列,这也解释了为啥子我一开始在root下老登陆不进去ftp。 5} finger ftp,这个命令主要是查看ftp这个用户的一些信息,包括登陆时间,默认家目录等等,其中,ftp这个用户的家目录会作为匿名登陆用户显示的目录(即是匿名用户的根目录)。 3.一些重要的概念以及操作 ftp localhost 这个的意思就是,以本地机器连入ftp,就是在你的Ubuntu上连入ftp啦,localhost实际上是指通过lookback接口向应用程序提供连结,localhost的IP是 127.0.0.1,你可以自己看成这个IP就是你自己电脑的IP地址,只不过是专门用来进行系统内部程序的通信用的。 chroot change root diectry,root指的是根目录,为什么会有这个呢,因为一旦别人连入你的ftp,它可以向上级访问目录,也就是说可以访问你的任何一个文件,这个 是不好滴,所以利用chroot可以把连进来的用户限制到一个目录里面操作,它能访问这个文件夹里的一切东西,但是就是不能跳出这个文件夹访问上级目录。 这个chroot相当重要。 chown 这个是改变文件的所属用户组的命令,初级阶段不太用的上,以后会说明。 4.自己环境下vsftp的功能,以及配置。下面主要说说自己的配置,顺带说明一些功能。 vsftp的功能: 允许匿名用户登录,登陆的目录为/srv/ftp(也即是我finger ftp得到的ftp用户家目录,这个是vsftp默认的),匿名用户只拥有下载权限,不具备上传,新建文件夹等权限,并且被限制在/srv/ftp目录下,不允许查看上级目录(比如我的/ect /boot等目录)。 允许本地用户登录,本地用户就是指你Ubuntu机器上的用户,比如root,ftp,xxx用户等等,本地用户拥有所有权限,进入的默认目录是/home/ftp(所以上面说建一个这个目录),并且可以访问机器上的任何目录。 开启FTP的日志功能,记录FTP的所有操作。在vsftpd.conf中很多配置是一环扣一环的,比如说如果write_enable没有开启,那么设置upload=YES也是没有用的。慢慢学习,就会知道一些。
3:创建用户
自己建立一个ftp2用户,并修改密码 sudo useradd -g ftp -d /srv/ftp ftpa sudo passwd ftpa 用户可以访问ftp server,正常连接,但如果禁止其不能terminal登录的话 sudo useradd -g ftp -d /srv/ftp -s /sbin/nologin ftpa 用户不能登陆,通过网上寻找发现 vsftp 会查找 /etc/shells文件,以判断其用户是否包含,默认情况下Ubuntu(openbsd)中的shells 没有/sbin/nologin,所以要通过手动添加来实现 sudo vi /etc/shells 添加/sbin/nologin 此时就可以实现ftp用户登录,terminal不能登陆的效果。至于默认的ftp用户 我们可以不用,查看/etc/passwd文件可知,ftp 属于 /bin/false,也不再shells中所以不能登录。
4:开启服务
sudo /etc/init.d/vsftpd restart

3:调用
try { FtpWeb ftp = new FtpWeb("10.53.132.52", "/srv/ftp/", "ftpa", "ftpa"); if (!ftp.DirectoryExist("tt")) { ftp.MakeDir("tt"); } ftp.GotoDirectory("./tt/", false); FileStream Stream = new FileStream(@"E:\Test\Test\Test\163074.xml", FileMode.Open, FileAccess.Read); byte[] bt = new byte[Stream.Length]; Stream.Read(bt, 0, (Int32)Stream.Length); Stream.Close(); DataSet ds = new DataSet(); ds.ReadXml(@"E:\Test\Test\Test\163074.xml"); string aa = ds.GetXml(); byte[] bts = Encoding.UTF8.GetBytes(aa); ftp.Upload("2.xml", bts); } catch (Exception ex) { Console.WriteLine(ex.ToString()); }
接下来我将对比两种方案的效率。
