Linux下ftp服务器安装与配置实验报告，包含实验步骤，实验结果以及总结

GNU nano 2.5.3

File: /etc/vsftpd. conf

By default the server will pretend to allow ASCII mode but in fact ignore

the request. Turn on the below options to have the server actually do aScII

H mangling on files when in ASCII mode

Beware that on some FTP servers, ASCII support allows a denial of service

ttack (Dos) via the command"SIZE /big/file"in ASCII mode. vsftpd

redicted this attack and has always been safe, reporting the size of the

raw file

H ASCII angling is a horrible feature of the protocol

#ascii_ upload_enable=YES

#ascii download enable=YES

You may fully customise the login banner string:

#ftpd banner=Welcome to blah FTP service

You may specify a file of disallowed anonymous e-maiL addresses

tly

useful for combatting certain Dos attacks

#deny email enable=YES

#(default follows)

#banned_email_file=/etc/vsftpd banned_emails

G Get Help o Write Out

here Is K Cut Text

Justify

对其中一些配置进行重写1按贩房:

1)禁止名访问

Allow anonymous FTP? (Disabled by default)

anonymous enable=No

2)允许本地访问

Uncomment this to allow local users to log in

local enable=yeS

3)修改写入权限

Uncomment this to enable any form of FTP write command

write enable=yes

4)修改欢迎页信息

t You may fully customise the login banner string:

#ftpd_banner=Welcome to DongTao's FTP service

5)设置p服务器在U1butu下的根目录1加在文件尾

#set local root

local_root=/ftp

修改完成接Cm+X保存设置后烬

7)注意

配置后要注释掉 etc//pam. d/vsf中的一句命令,否则用新添加的用户

名访问服务器时会报错。

dongtaodubuntu: s ftp 192.168.. 128

COnnected to 192.168.111.128

530 Login incorrect

dongtaogubuntu: /etcs sudo nano pam.d/vsftpd

pam sheLLs. so

注释掉后就可以正常登录

配置完成重启服务器

dongtao@ubuntu: /etcs sudo service vsftpd restart

3.创建用户并设置密码

dongtaogubuntu: - s sudo useradd -d -/ftp-M dongyong

dongtao@ubuntu: -S sudo passwd dongyong

Enter new UNIX password:

Retype new UNIX password:

passwd: password updated successfully

dongtaoaubuntu: s

4.太地登录服务器(在配置服务器过程中,配置文件默认|ca/enab/e=yEs

先查看批服务器的地址,即 Ubuntu的|P

dongtao@ubuntu: /etcs ifconfig

可以看到成功登录,并且什p下有个目录data。

5,{bmtu下与和通信(文件互传

1)在data中创建文件test

dongtaogubuntu: S touch -/ftp/data/test

在家目录下创建文件test1

dongtaogubuntu: S touch -/ftp/data/test

dongtaogubuntu: S touch/test1

2)录1服务器后想要在服务器上上传下载文件,那么就要给成员供访问的

文件夹的一些权限,下面命令给所有用户三种用户如及data子目录

下文件的最高权原。

dongtaoqubuntu: -S sudo chmod-R 777 /ftp/data

登录服务器,将家目录下的test1上传到服务器(先转换到data目录,因为用户对

这个目录有最高权限)

ftp> cd data

250 Directory successfully changed

tp> put test1

local: test1 remote: test1

200 PORT command successful. Consider using PASv

6. Window与Ⅶmtu上和服务器的通信

在 Windows上登录和计服务器失败,需要改变虚拟机的∥P地址,这里我们把细航

记得网络适配器改为桥接方式即可。

7.注意事项

1若一开始就设置虚拟机网终为桥接模式,则安装印服务器会关败

2配置时要注释掉etc1pam印中的一句命令,否则用新添加的用户

名访问服务器时会报错。

3P配置完成,一定要重启跟务器

四、实验总结

本次实验学会了怎样在 Ubuntu下安装并配置tp服务器,通过ftp服务器实现了

Windows主机与 Ubuntu虚拟机间的通信,深切感受到计算机科学领域的博大精深!
