RTOS Ready WebDAV Server

The Barracuda Web Server's WebDAV plugin is secure file sharing software that lets users easily access files on the server from any type of client computer such as from a PC, iPhone, Android, Linux, etc. The file server uses WebDAV which is a set of extensions to the HTTP(S) protocol that allows a web server to appear as a standard network drive. WebDAV clients are native to Windows, Mac OS X, Linux, etc.. No software needs to be installed on the client computer, and one can simply map/mount a drive from one of these operating systems to the WebDAV server.


You may be familiar with sharing files via your company file server using SMB/CIFS on your local Intranet. This is suitable for a closed network, but unsafe over the Internet. WebDAV is different from SMB as it uses HTTP for transporting files and is designed from the ground up to be secure on the internet. The HTTP protocol is the same protocol used by web-browsers. WebDAV can also use HTTPS, secure and encrypted HTTP, allowing no one to eavesdrop on your file transfer. The Secure File Server can bypass company firewalls and proxies since the communication protocol is HTTP. Consequently, it is possible to securely access your files from anywhere.

WebDAV Versus FTP

The WebDAV server is much easier to use than a typical FTP server since you access the remote file server as a standard drive. WebDAV is a more modern protocol than FTP and can be seen as the successor to the FTP protocol.

Unlike SMB/CIFS, WebDAV can be used from mobile devices such as iPhone, iPod, iPad, Android, and Blackberry -- that is, you can work directly on files in your embedded devices using any mobile device.

The one minute video to the right shows how to connect a Windows and Mac computer to the FuguHub server, which includes our WebDAV plugin. Follow the instructions in the video and use the WebDAV test server URL below.

Web File Manager

The WebDAV server can be used "as is" or it can be used in combination with our Web File Manager. The two products, when combined, are referred to as the Web File Server in our documentation.

OpenID Connect Compatible

Users may initially use a browser and create a WebDAV session URL using Single Sign On (SSO). See our WebDAV Single Sign On Example for details.
