Vsftpd Migration instruction

Everyone must have doubts about vsftpd transplantation. This article is a little bit of my experience for your reference:

1 download

Download the latest version of the source package at https://security.appspot.com/vsftpd.html#download. This article takes the vsftpd-3.0.2.tar.gz version as an example.

If the above download address is not accessible, you can also download vsftpd-3.0.2.tar.gz locally.

2 decompression

$mkdir ~ / vsftpd

$cp vsftpd-3.0.2.tar.gz ~ / vsftpd

$cd ~ / vsftpd

$tar xzf vsftpd-3.0.2.tar.gz

$cd vsftpd-3.0.2/

The "~" in the command indicates the current user directory, for example, the user working on the Linux host is: veryarm, then the "~" in the command represents the path: / home/veryarm/ directory.

3 configuration

$export PATH=$PATH:/usr/local/arm-2010q1/bin # cross-compilation tool path to add system environment variables!

$vi Makefile

After opening the Makefile file, modify the value of the CC variable as follows:

CC = arm-none-linux-gnueabi-gcc

Among them

CC: specify cross-compilation tools, such as arm-none-linux-gnueabi-gcc, arm-linux-gnueabihf-gcc, arm-linux-gcc, etc., which correspond to the cross-compilation tools used on the target board.

4 compilation

$make # compilation, if the computer is a multi-core CPU, such as quad-core, using make-J4 can improve the compilation speed

After make, two files are generated in the current directory: vsftpd and vsftpd.conf, which we want to use.

5 copy files

Copy the generated vsftpd to the target board / usr/sbin directory, vsftpd.conf to the target board / etc directory, and add vsftpd as executable:

$cp vsftpd / usr/sbin # copy the execution file to the target board

$cp vsftpd.conf / etc/ # copy the configuration file to the target board

$chmod + x / usr/sbin/vsftpd # add executable permissions

6 configuration

Use vi to open the vsftpd.conf file, and configure it as follows to achieve normal upload and download:

Anonymous_enable=NO # the default YES is changed to NO

Local_enable=YES # removes the preceding # comment symbol

Write_enable=YES # removes the preceding # comment symbol

Anon_upload_enable=NO # remove the preceding # comment symbol and change YES to NO

Anon_mkdir_write_enable=NO # remove the preceding # comment symbol and change YES to NO

Anon_other_write_enable=NO # removes the previous # comment symbol and changes YES to NO (it may not be in this new version)

Chroot_local_user=YES # removes the previous # comment symbol and changes the line to restrict FTP users to the home directory

Chroot_list_enable=YES

Chroot_list_file=/etc/vsftpd.chroot_list

Allow_writeable_chroot=YES # add this line to the end of the file

You will need to restrict users to / etc/vsftpd.chroot_list, one user per line.

Then use the command configuration on the target version:

$adduser nobody # vsftpd default configuration requires

$mkdir / usr/share/empty # vsftpd default configuration requires

Create a local user and set the password:

$adduser ftpadmin

Changing password for ftpadmin

New password:

Retype password:

Password for ftpadmin changed by root

7 Open vsftp

Once configured, open vsftp on the target board, and command:

$vsftpd &

Notice that there is another &. If you want vsftpd to boot, you can add this command to the end of the / etc/profile or rc.local file.

8 client test

Configure the target board IP, so that it can communicate with the computer ping, and then open the client on the computer, enter the target board IP, user name, password, you can connect.
