============

To safely use secure-FTP with Serv-U, using SSL/TLS to encrypt the FTP
session and file tranfers, you *MUST* create your own certificate. To do
this go to the 'Server | Settings | SSL Certificate' tab and fill in your
own entries for the certificate presented there (you can get context
sensitive help for this by pressing F1).

The reason for this has to do with the way SSL works. Associated with the
certificate are two encryption keys named "private key" and "public key".
To keep FTP traffic secret the private key has to be a secret. The default
certificate that gets installed has the same keys for every installation
and is thus no secret.

EDITIONS
========

Serv-U comes in three editions: A free "Personal Edition" that provides all
the functionality needed for personal home use. Next is "Standard Edition",
intended as the file sharing solution for most personal and business users.
"Professional Edition is for corporate FTP sites that need many virtual FTP
servers and high-volume traffic. For a complete overview of Serv-U's
Editions please see http://www.Serv-U.com/


TRY-OUT
=======

Serv-U is trialware, which means you can try it before you decide to
register. Feel free to pass the try-out version around, but please do not
distribute any registration keys. The 30 day trial version is fully
functional and identical to "Professional Edition". After the trial time
has expired Serv-U automatically becomes a "Personal Edition" server.


INSTALLATION/UPGRADING
======================

Serv-U comes as a self-extracting installation executable. Follow the
interactive setup and it will do the hard work for you. An uninstall
program is also included which makes complete removal of all Serv-U files
easy.

To upgrade from a previous version the same installation program can be
used. It will automatically look for and upgrade your existing installation
of Serv-U. Of course, it never hurts to make a backup of your Serv-U
directory before upgrading.


NOTES FOR SYSTEM ADMINISTRATORS
===============================

The self-extracting installation executable is a zip-file in itself which
can be unpacked using any unzip utility. This lets one scan the contained
executables for viruses if needed. Also, instead of the interactive setup
the installer can be run silently. The online help file has more
information relevant to system administrators, such as startup options,
installer  options, and network installation.
