WU-FTPD 2.6.1 Release Notes (September 2008)

WU-FTPD 2.6.1 Features
Following are the WU-FTPD 2.6.1 features supported on the HP-UX 11.0, HP-UX 11i
v1, and HP-UX 11i v2 operating systems:
Virtual FTP Support
Virtual FTP support allows you to manage an FTP server for multiple domains on the
same machine.
Virtual FTP allows an administrator to configure a system to display a different banner,
log file, and directory to a user when the user is connected to different domains on the
same system. The advantage of virtual FTP support is that the identity of the machine
is hidden. Also, this feature allows a single machine to act as multiple FTP servers for
multiple domains.
Figure 1-1 shows a graphical representation of an FTP server, ftp.domain.com,
hosting two virtual domains, ftp.animals.com and ftp.flowers.com.

(Virtual Domain 2)
(FTP Server)
In Figure 1-1, 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. 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. If you do not want to place a copy of one
or all the FTP configuration files in the virtual host directory for any host, you can use
the master copy.
