背景:

  有一台主机,安装了windows7,在其安装了virtualbox,然后安装了ubuntu虚拟机。在windows7上安装SecureCRT来ssh连接ubuntu虚拟机。一般在windows上面下载软件,然后通过vsftp上传到ubuntu虚拟机上。但是这样非常麻烦,现在考虑使用sftp协议来直接传输。
方案:

  使用SecureCRT软件ssh连接到ubuntu虚拟机。然后在SecureCRT上面打开SFTP会话,如下图所示:  

SFTP命令

  进入到sftp命令窗口以后,就可以通过sftp命令来进行文件互传的操作。下面主要介绍一下sftp命令的含义。

sftp> helpAvailable commands:ascii  Set transfer mode to ASCIIbinary Set transfer mode to binarycd pathChange remote directory to 'path'lcd path   Change local directory to 'path'detail remote-path Display system information about remote file or folderldetail local-path Display system information about local file or folderchgrp group path   Change group of file 'path' to 'group'chmod mode pathChange permissions of file 'path' to 'mode'chown owner path   Change owner of file 'path' to 'owner'exit   Quit sftphelp   Display this help textinclude filename   Include commands from 'filename' Alternate: < filenameget [-r][-a | -b] remote-path  Download file -r downloads directory recursively force ascii (-a) or binary (-b) modeln [-s] existingpath linkpath  Hardlink / symlink remote filels [options] [path]Display remote directory listinglls [options] [path]   Display local directory listingmkdir path Create remote directorylmkdir pathCreate local directorymv oldpath newpath Move remote filelmv oldpath newpathMove local fileopen [user@]host[:port]Connect to remote hostput [-r][-a | -b] local-path   Upload file -r uploads directory recursively force ascii (-a) or binary (-b) modepwdDisplay remote working directorylpwd   Print local working directoryquit   Quit sftprename oldname newname Rename remote filelrename oldname newnameRename local filermdir path Remove remote directorylrmdir pathRemove local directoryrm pathDelete remote filelrm path   Delete local filesu usernameSubstitutes the current user This is only supported with VShell for  Windows 3.5 or later.type [transfer-mode]   Display or set file transfer modeview remote-path   Download and open fileversionDisplay protocol versionsftp-- help 可用命令: cd 路径更改远程目录到“路径” lcd 路径   更改本地目录到“路径” chgrp group path   将文件“path”的组更改为“group” chmod mode path将文件“path”的权限更改为“mode” chown owner path   将文件“path”的属主更改为“owner” exit   退出 sftp help   显示这个帮助文本 get 远程路径   下载文件 ln existingpath linkpath   符号链接远程文件 ls [选项] [路径]   显示远程目录列表 lls [选项] [路径]  显示本地目录列表 mkdir 路径 创建远程目录 lmkdir 路径创建本地目录 mv oldpath newpath 移动远程文件 open [用户@]主机[:端口]连接到远程主机 put 本地路径   上传文件 pwd显示远程工作目录 lpwd   打印本地工作目录 quit   退出 sftp rmdir 路径 移除远程目录 lrmdir 路径移除本地目录 rm 路径删除远程文件 lrm 路径   删除本地文件 symlink existingpath linkpath  符号链接远程文件 version显示协议版本

这里在详细说明一下远程目录和本地目录。

远程目录:ls查看到的是ubuntu虚拟机上面的目录

本地目录:lls查看到的是windows实体机上面的目录。

实例:

假设我需要实现windows下的e:\sftp\test1.txt和ubuntu下/home/enadmin/test2.txt的互换,可以进行一下操作:

put操作:windows->linux

查看目录权限

拷贝文件

注意点:这里需要注意权限的问题。加入我是使用enadmin账户初始连接ubuntu的,那么我put的文件只能放到文件夹权限是enadmin的目录下,不能放到文件夹权限是root的目录下。如果想放到文件夹权限是root的目录下,那么初始就使用root账户连接ubunut,然后再创建sftp会话,这样就可以了。

get操作:linux->windows

get操作没有权限设定
