how to run multiple ftp servers on 1 public ip ?

Hello,

In addition to what others have said, i would like to add an "For Interest"
link, in case you are curious about Host Headers and how it is supposed to
be in HTTP:

<a style='text-decoration: underline;' href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23" target="_blank">http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23</a>

As you have already been told, Host Headers are not part of FTP, and you
must therefore use another method to distinguish FTP servers (for example
port or IP).

You could ask your ISP to send you a RIPE form (if youre in Europe, not sure
about the US)
You can then be assigned another block of IP addresses, and have a whole
other IP address for each server, or virtual server.

Failing that, look at the port suggestions posted before.

The HTTP 1.1 specification has something called the "host" header, which
allows a webserver to host multiple websites on a single IP address on port
80. It is up the client to specify which website they want to access by
sending the Host: HTTP header. The webserver uses this to determine which
website the request should be routed to.

FTP does not have any comparable.

The more common way to do this is to have all accounts who will use the FTP
server be part of a group.

Give permissions to the group to have read only (no listing) access to the
directory just above the others. Then give read/write permissions for the
account in the appropriate directory.

Of course, this assumes a certain directory structure for this.

You can use a script for when they logon to be put in a specific directory.

But this is the very reason many people go to other products which work
around this issue.
