15.5. vsftpd Configuration Options
Although
vsftpd may not offer the level of customization other widely available FTP servers have, it offers enough options to fill most administrator's needs. The fact that it is not overly feature-laden limits configuration and programmatic errors.
All configuration of
vsftpd is handled by its configuration file, /etc/vsftpd/vsftpd.conf. Each directive is on its own line within the file and follows the following format:
<directive>=<value>
For each directive, replace <directive> with a valid directive and <value> with a valid value.
Important
There must not be any spaces between the <directive>, equal symbol, and the <value> in a directive.
Comment lines must be preceded by a hash mark (
#) and are ignored by the daemon.
For a complete list of all directives available, refer to the man page for
vsftpd.conf.
Important
For an overview of ways to secure
vsftpd, refer to the chapter titled Server Security in the Security Guide.
The following is a list of some of the more important directives within
/etc/vsftpd/vsftpd.conf. All directives not explicitly found within vsftpd's configuration file are set to their default value.
