Using the File Fabric’s SFTP protocol adaptor to work with multi-cloud files from a Linux Console

multi-cloud SFTPSFTP is an acronym for the SSH File Transfer Protocol. SFTP is the preferred option to FTP because it is inherently more secure and is able to piggyback on an SSH connection.

You may have often found yourself on a linux console where you need access to a file that you have stored on Google Drive, an Amazon  S3 or Azure instance, or perhaps you want to transfer a file back from a local file system to one of these accounts. In either case it would be good to be able to do this without installing and setting up additional software.

File Fabric Feature Focus – CloudZip provides zipped downloads of folders

We recently rolled out a brand new feature that we would like to highlight, called CloudZip.

CloudZip enables users to download zipped copies of their folders in .zip, .tar, or .tar.gz formats.

Ito works for any of the on-premises or on-cloud endpoints that are mapped to a File Fabric Account.

Turbo Charge Your Company’s Google Drive Experience

Although it is one of more than fifty storage clouds supported by the SME Enterprise File Fabric, Google Drive is not just a storage service. It also provides built-in integration with Google’s Web apps for creating and editing text documents, spreadsheets, slide shows, drawings and maps.

One of our customers, a college in the United States, asked us to look at how they could leverage Google Docs’ application integrations from within Storage Made Easy. In response to this request we implemented two productivity features that allow SME users to integrate Google’s Web based editors into their workflows in novel and useful ways.

Using Midnight Commander to work with Amazon S3, OpenStack, DropBox, OneDrive and almost any other Cloud

Midnight Commander is probably the most popular command line file manager in the world, and certainly for Linux distros. Its design was initially inspired by the classic two pane interface that was found in Norton Commander which was a DOS file manager (for those who remember !).

One of the unsung features of the Midnight Commander (also available on other platforms including phones (I used to use this on my old Nokia N900) and windows and mac) is that it can connect to server over FTP.

This is interesting from a Storage Made Easy viewpoint as although SME providers a full suite of Linux tools, SME also provider protocol interoperability as part of its Cloud Gateway features. What is this I hear you ask ? Well, simply put, it enables files you have stored on public or private storage to be accessible over any of the protocols Storage Made Easy exposes ie FTP, FTPS, WebDav, S3, SFTP.

SME Protocol Gateway

Midnight Commander supports the FTP protocol which makes it easy to get direct access to any storage that is added to a SME Account using the SME FTP cloud protocol adaptor. To do this:

Choose the Left or Right option
Choose FTP link
Enter connection to SME as follows:

username:password@storagemadeeasy.com

or if you are using the SME EU Server:

username:password@eu.storagemadeeasy.com

Midnight Commander FTP

The net result is a very easy way to bring the cloud into the linux desktop integrated with tools you already know and use. This can be used with the SME Personal CLoud plan, Business Team, and on-site enterprise editions of the product.

New Folder Sharing feature for team users

We have implemented a new folder sharing feature for Business Cloud / on-site Enterprise File Share and Sync Users. It simply provides the ability to share folders and sub-folders of files with external companies or other users who can receive the link, enter the password and gain access to the files without the need for an SME Account.

The video below shows the feature in action.

Accessing OpenStack, RackSpace, Google Drive, OneDrive, DropBox + more using Storage Made Easy and Transmit for Mac

If you have come across this post whilst researching how to access other storage clouds from Transmit then have a look at our Getting Started Guide to show you how you can register for a free account and get on with mapping your chosen Storage Cloud to the SME Cloud Gateway. When you are ready you can register for a free account here.

As many of you who use it know, CloudDav, from SME adds a WebDav layer over any Cloud, even if the underlying clouds do not support WebDav. SME does no however allow the native Mac WebDav client to connect direct because the performance of the native Mac WebDav client is notoriously abysmal for those with large amounts of files.

You can however choose to use other Mac clients to connect to the Cloud Providers that you have mapped to the SME Gateway. We highlighted Forklift as such a client in a prior post, and you can also choose to use Transmit from Panic.

Once you have CloudDav enabled you can choose to access your clouds, mapped via the SME Gateway, through Transmit. First choose to connect over WebDav as in the screenshot below:

Transmit DropBox

You can then choose to connect directly inside of Transmit or as a Virtual Drive that will appear in Finder.

Transmit  also has a very nice sync feature that will sync between folder structures. In this way you can sync files with Transmit and SME from different Cloud Storage Providers to your desktop.

SME CloudDav is available with every account, even free accounts, although on free accounts it is restricted to 150MB of use per month. The CloudDav protocol Adaptor is just one of the protocol adaptors that SME provides, the others being FTP, SFTP and a compatible S3 API. All protocol adaptors are available in the Storage Made Easy Enterprise edition as part of the Cloud Gateway which the SME Enterprise File Share and Sync is built upon.

WebDav the interoperable protocol for file and document access

WebDav is an acronym for Web Distributed Authoring and Versioning and can also be referred to as just plain old DAV.

WebDav is an extension of the HTTP protocol that was originally designed by Jim Whitehead from the University of California at Santa Cruz in 1996 when he was working at the World Wide Web consortium and it later became an Internet Engineering Task Force (IETF) standard.

WebDav was built as an interoperable standard to support remote collaborative authoring of Web sites and individual documents, as well as remote access to document based systems.

Today it It is the most popular network file-system protocol for use across the Internet, and although it has been integrated as a interoperable layer into many existing product implementations it is also notably missing as an interoperable API standard from many, such as DropBox, Google Drive, Amazon S3 and more.

The Storage Made Easy WebDav Gateway

SME provide a way to access any mapped cloud by secure WebDav irrespective of whether the underlying Cloud Supports the WebDav protocol natively. As WebDav is so well supported in many desktop and mobile Apps this means that Cloud Data can easily be integrated and accessible without having to move it to access the features of a particular Application that is WebDav enabled.

Connecting to WebDav Servers and Windows Shares

SME can also be configured to connect to servers that support the WebDav protocol. This use of WebDav from a SME perspective is using WebDav as a back end cloud to store data rather than exposing existing clouds to be accessible using the WebDav protocol.

Many existing NAS or SAN devices such as those as the NetGear ReadyNAS and the Synology devices range already provide WebDav as an access protocol to access data. Also existing web servers such as Apache can also be configured to use WebDav using the Mod Dav extension.

Many users of SME want to expose windows file shares and make them directly available through the SME service to all devices. The most appropriate and secure way to do this is not to expose such shares directly but to configure Microsoft Internet Information Server to expose these shares over WebDav.

Advantages of WebDav for Windows File Sharing

This has the following advantages:

Seamless integration with the IIS Manager

A secondary protocol provides a security DMZ with regards to direct access to windows shares

IIS WebDAV can be enabled at the site level, allowing IT administrators to restrict WebDAV access to specific sites on a server.

IIS WebDAV supports per-URL authoring rules, allowing administrators to specify custom WebDAV security settings on a per-URL basis. This fine-grained control gives administrators the ability to maintain one set of security settings for normal HTTP requests and a separate set of security settings for WebDAV.

IIS WebDAV supports both shared and exclusive locks to prevent lost updates due to overwrites

WebDAV supports secure connection as well. By enabling HTTPS over all WebDAV connections, security is fortified. SSL certificates can also be installed to increases security measures

Why WebDav as a Cloud Connector ?

WebDAV is an optimized protocol for document access over http. It is proven as being latency independent and is efficient over wide area networks especially in contrast to file protocols such as NFS and CIFS.

Using secure WebDAV ensures the data is encrypted during transmission and due to the optimizations that data is stored efficiently and quickly .

Why Not The Common Internet File System (CIFS)

CIFS is the standard way that windows users share files across corporate intranets and the Internet with a secure VPN connection.

To expose such shares directly to the internet or to other none windows PC’s it is needed to use a bridging technology. Samba is often used as such as technology. With Samba, the ports 139/tcp and 445/tcp are exposed over a public IP Address. Once this is done such shares are accessible.

The drawbacks of this are:

– The CIFS protocol used by Windows file sharing does not provide data encryption

The protocol itself is quite chatty.

No level of security indirection

CIFS is is an optimized protocol for access to data over a network that has been extended by VPN and has been used in this context by many companies for a long time. The disadvantage of this is that all devices have to support , be setup, and work with the VPN. preventing access by some devices and Apps and making Adhoc ‘on the fly’ access difficult.

Securing WebDav Servers

It is beyond the scope of this blog post to go into great detail on the steps required to secure WebDav servers but Microsoft has a very good guide on how to secure the IIS WebDav Service. This can be accessed at:

http://technet.microsoft.com/en-us/library/cc778809%28v=ws.10%29.aspx

In addition to this you should note the following best practices:

Folder Permissions: Use non-anonymous authentication. Modify the NTFS permissions on the folder to only allow the access necessary to the users who require such access

Prevent File Execution: If you are only using WebDAV as a file store and not using it to display web pages, then execute permissions should be removed from that site or folder.

Apache WebDav servers can be configured to use LDAP authentication and also two factor authentication and any deployments should consider implementing these.

New Storage Made Easy Google Chrome Cloud Unifier File Manager Extension

We’ve added a new Storage Made Easy Chrome extension to the Chrome Web Store. The sole function of this extension is to enable auto-login and launch of the SME Web File Manager for quick access.

The SME Web File Manager is a hierarchical file manager which makes it ideal to deal with large data set and also data from different on-premise or public cloud storage, which are unified in the file tree. A Storage Made Easy Account is needed but a free account can be signed up directly from the extension.

The reason for this extension was to make it a lot easier for users to be able to gain access to the Web Cloud File Manager for one of our business customers who had equipped their salesforce with Chromebook Pixel’s.

The Web File Manager enabled them to have a workflow which included editing and commenting of documents directly from the Chromebook on various clouds that they used which includes BaseCamp and Amazon S3.

The extension can also be used for securely sharing files which include setting passwords on files and/or time expiry.

The web file manager, from a single user perspective provides a very nice way to work with data between cloud providers and even collaborate with other people using Business Group WorkSpaces. For business users it provides a complete collaboration environment between user which includes files editing, file commenting, file versioning and file locking.

Cloud Computing Use Case: Automatic notifications of new or changed iWork Numbers documents stored on Google Drive

We had an interesting Use Case recently in which the requirements were as follows:

The Company in question had a Google Apps Account and therefore used Google Drive for their Storage. They had a number of iWork Numbers documents that were modified by their team members whilst on the move using iWork and iPad’s. Currently their process was editing the files, and then trying to send the resultant file via email to other team members. Due to file size some files were not received and in general the email server was quickly eating up storage. What they cam to SME for was to figure out how they could refine this process.

With Storage Made Easy the process became much simpler. Firstly the company subscribed to a Cloud File Server SaaS Account. The SME Cloud Admin then added the companies Google Drive account to be accessible via SME and invited other team members to be part of the Cloud File Server. On the Folder(s) in question the Cloud Admin simply set permissions so that relevant team members had access and added a notification rule specific to keynote file to ensure that all subscribers to the shared folder received an email notification on new files or updates to existing files. As per our prior article on Twitter and SMS Gateways on these changes to file events SME can easily generate instant SMS notifications.

As Storage Made Easy enables WebDav above any Cloud added to it then Google Drive becomes instantly accessible via WebDav. For the Company this means that they can simply open and create new keynote files directly in Keynote from their shared Google Drive folder and then on completion simply save them back. The very act of doing this generates a file event on completion which send an email and/or SMS to users subscribed to the shared folder vastly simplifying the process.




Another added benefit to the company is the complete end-to-end joined up audit tracking they get on all Google Drive documents:
