This is a server software with excellent performance. Because of its many powerful functions and ultra-high throughput, over 60% of FTP servers on the Internet use it.
Installation and running
The following uses RedHat Linux as an example.
1. Installation
Based on different service objects, FTP services can be divided into two types: System FTP server, which only allows valid users on the system to use, and anonymous FTP server, it allows anyone to log on to the FTP server. After connecting to the server, enter anonymous in the logon prompt to access the server. For these two services, you can install the RPM package of WU-FTPd on the first disc of RedHat. You only need to enter the system as root and run the following command:
RPMs-IVH anonftp-X. x-x.i386.rpm
Rpm-IVH wu-ftpd-x.x.x-x.i386.rpm
-X. X-X and-x. x. x-X are version numbers.
2. Start
Like Apache, wu-ftpd can also be configured as Automatic startup: run the setupProgramSelect wu-ftpd in the "System Service" option and press the [OK] button to exit.
Automatic Start is convenient, but when we change the WU-FTPd configuration file, we need to use manual start:
Start:/usr/sbin/ftprestart
Disable:/usr/sbin/ftpshut
FTP Server Configuration
To ensure the security of the FTP server, you must set some important configuration files to better control the user's access permissions. These configuration files are:/etc/ftpusers,/etc/ftpconversions,/etc/ftp-groups,/etc/ftpphosts,/etc/ftpaccess. Using these files, you can precisely control who, at what time, from where the server can be connected, and check and track the work they have done after connection.
