same system. The advantage of virtual FTP support is that the identity of the machine is
hidden. Additionally, this feature enables a single machine to act as multiple FTP servers
for multiple domains.
Figure 1 shows a graphical representation of an FTP server, ftp.domain.com, hosting
two virtual domains, ftp.animals.com and ftp.flowers.com.
Figure 1 Structure of an FTP Server Hosting Two Virtual Domains
ftp.domain.com
ftp.animals.com
(Virtual Domain 1)
ftp.flowers.com
(Virtual Domain 2)
(FTP Server)
In Figure 1, a user connected to the FTP server ftp.domain.com through the domain
ftp.animals.com receives a different banner and directory than a user who is
connected to the same server through the domain ftp.flowers.com.
Setting up Virtual FTP Support
The configuration file /etc/ftpd/ftpservers contains a set of virtual domain names
that the FTPD server can use for each virtual domain. Using the virtual domain name,
you can define the FTP configuration files ftpaccess, ftpusers, ftpgroups,
ftphosts, and ftpconversion files on a per-domain basis. If you want to place a
copy of one or all the FTP configuration files in the virtual host directory, create a directory
in the /etc/ftpd directory with a name similar to the virtual domain name, and copy
the FTP configuration files to that directory. Otherwise, you can use the master copy.
