Load Balancing of Wing FTP Server

Configuration has yet to be fully verified, Kemp Support will gladly assist if your Wing FT traffic is not flowing as expected.

 

1   Introduction

Wing FTP Server is an easy-to-use, secure and reliable FTP server software for Windows, Linux, Mac OS and Solaris. It supports multiple file transfer protocols, including FTP, FTPS, HTTP, HTTPS and SFTP, giving your clients flexibility in how they connect to the server. And it provides admins with a web based interface to administrate the server from anywhere. You can also monitor server performance and online sessions and even receive email notifications about various events taking place on the server.

So I am currently on a pet project to setup a load balanced FTP Server(s). We will be setting up two servers with NetScaler balancing the two. We will be running Ubuntu with VSFTP. We want this to be setup so that if I were to FTP something to say FTP1 that it would show up on either server.

For example if I load File A on FTP1 (cause that is where NetScaler sent me) I should be able to see File A on FTP2 as well.

I have some small time experience with some Ubuntu at home but never dealt with it in an enterprise environment and never really dealt with FTP in this way...so any and all advice is welcome. Sorry for the long, potentially confusing, post.
