This example shows how you might set up virtual hosts. Virtual hosting is
where different clients access your machine on different IP addresses (virtual
IPs) and get redirected to different ftp sites.

For example, if your machine responds to two IPs - 127.0.0.1 and 127.0.0.2,
you could have the two different IPs represent two totally different FTP sites.

For this example, we are going to build on the "INTERNET_SITE" example.

Step 1) Set up a virtual IP address.

ifconfig eth0:1 192.168.1.10 up
(the standard IP address is 192.168.1.2)
(note - this isn't quite complete, the route for local connects hasn't been
added, but it will do for now)


Step 2) Create a user / location for the new virtual site.

useradd -d /var/ftp_site2 ftp_site2
chown root.root /var/ftp_site2
chmod a+rx /var/ftp_site2
umask 022
mkdir /var/ftp_site2/pub
echo "test" > /var/ftp_site2/pub/content


Step 3) Modify the existing site to respond to the primary IP.

Edit /etc/xinetd.d/vsftpd, and add the config line:

bind = 192.168.1.2


Step 4) Create the new site, responding on the virtual IP.

cp /etc/xinetd.d/vsftpd /etc/xinetd.d/vsftpd2

Edit vsftpd2, and change
- The bind line to refer to the IP address 192.168.1.10
- Add the line
server_args = /etc/vsftpd_site2.conf

This launches this FTP site with a different vsftpd configuration file.

cp /etc/vsftpd.conf /etc/vsftpd_site2.conf

Add two lines:
ftp_username=ftp_site2
ftpd_banner=This is the alternative FTP site.


Step 5) Restart xinetd and test!

/etc/rc.d/init.d/xinetd restart
