  1. Select and install FTP server software

If you select "ftpd" when selecting to start the process during LINUX installation, after installing the LINUX system, it has installed a default FTP server to the system. We can use it to implement the functions of the system FTP server. We only need to customize the settings based on our needs.

In most LINUX releases, mongoingtonuniversity FTP is used. It is a famous FTP server software, generally referred to as wu-ftp. It is powerful and can run well on many UNIX operating systems, such as ibm AIX, FreeBSD, hp-UX, NeXTstep, Dynix, SunOS, and Solaris. More than half of FTP servers on the Internet use it. Wu-ftp has many powerful functions and is suitable for the management requirements of FTP servers with high throughput:

1) The user can automatically compress or decompress the file while downloading the file;

2) Different access restrictions can be imposed on machines on different networks;

3) records the upload and download times of files;

4) information about transmission can be displayed, so that you can understand the current transmission status in a timely manner;

5) You can set the maximum number of connections to improve efficiency and effectively control the load.

  Ii. Composition of wu-ftp

After wu-ftp is installed, you will see the following five executable files in the/bin directory:

Ftpd FTP server program

Ftpshut is used to close FTP server programs

Ftpcount shows current online users

Ftpwho: view the current FTP server connection status

Ckconfig check if FTP server settings are correct

In addition to these executable files, it also generates seven configuration files under the/etc and/var directories:

/Etc/ftpusers

/Etc/ftpaccess

/Var/run/ftp. pids

/Etc/ftpconversions

/Var/log/xferlog

/Etc/ftpgroups

/Etc/ftphosts

After wu-ftp is installed, a special user ftp is created and an ftpd directory is created under the/home directory. When you log on anonymously, will be automatically located in this directory. In this directory, several subdirectories are usually created.

/Home/ftpd/bin stores executable files for FTP users
