Disabling Directory Listing on Amazon Linux

The first step in disabling directory listing is to find the httpd.conf file.

On Amazon Linux, you'll find it in /etc/httpd/conf

Open the file using your favourite text editor.

Locate a a line which looks a bit like this …

Options Indexes FollowSymLinks

Remove the Indexes keyword from the list of options.

Save the file

Restart Apache.

Now if you try and browse to the directory, you'll get something like this.

CopperEgg Servers Map

Just been having a play with a cool new "beta" feature from CopperEgg, it's called Servers Map.

I strongly suggest those who are interested give it try. Great tool for understanding what's talking to what within your infrastructure (and your web application).

For those of you not familiar with CopperEgg, they are a "Cloud Computing Systems Management" company. There products mostly fall into the SaaS category with monthly subscription payment models. 

CopperEgg requires a small agent to be installed on the servers or instances you wish to monitor. You get an API key which links each agent to your account.

As soon as the agent is installed, literately seconds later, your CopperEgg dashboard lights up with some fantastic information.

There are heaps of other features so I won't go into them all, the usual suspects are there, including alerting, reporting, dashboard etc. I'm definitely becoming a big fan.

You can register for a free 13 day trial of CopperEgg and it's excellent monitoring service @ www.copperegg.com.

Definitely worth a butchers hook.




Here is a sample of the output that you can get from Servers Map. Shows which services and applications are using what ports to communicate with other stuff both on you local network and the outside world.

Amazon WorkSpaces Sync


Amazon have recently released a complimentary service for Amazon WorkSpaces, called Amazon WorkSpaces Sync.

The product, as the name suggests, is used to Sync data between a users local device, PC and Mac only at this point, and their Amazon WorkSpace. Like DropBox or similar file syncing services.

WorkSpaces Sync is backed by the AWS S3 service, so don't forget that you will be invoiced for the storage you consume. 

I'd be surprised if the service comes with bundles of storage since everything else AWS is per-for-what-you-consume. But they may offer some discount bundles or pricing models. 

The download, installation and configuration of the product is quick and easy. 

The client needs to be downloaded and installed onto a) your local device and b) your Amazon WorkSpace.

I imagine overtime, Sync will ship as a standard part of the WorkSpace bundles, the users can then just install it on to their local devices and be up and running.

In my case I installed Sync to on to my MacBook.

I've included a few screenshots below.


Once the client is installed, you're prompted to enter you WorkSpace registration code (this is the code that you were issued with then you were initially allocated a WorkSpace.
Once you enter the Reg code, you pop in your UserID and Password and the magic happens.


You can configure the location of the Sync folder using the preferences control panel that is shown after your credentials have been approved.


After the configuration wraps up, you can use the widget that's located in your system tray (for Windows) or the menu bar for Mac OS to de-register the computer from the service.



I've not quite figured out how to adjust the Sync Folder Path yet, I'll have a chat with the product dudes in AWS to find out.

The Amazon WorkSpaces Sync client does exactly what it says on the tin. 

A few extra things I think I'd personally like to see are:
  • Client for mobile devices. (Which opens the whole MDM can of worms!)
  • File Sharing features (Mail client plugins to share attachments, share file context menu short cut)
  • Visioning. (Right click, restore previous versions?)
  • Maybe, a Web Interface for the Sync Client.
Once WorkSpaces Sync includes those few extra features I think it will be a viable alternative to drop box and if it included as part of the WorkSpace bundle, why would you need to go anywhere else.
