Solution to udisks helper error

Debian 6.x/7.x relies on udisks to handle accessing, reading and writing of storage media. The utility udisks is an interface to the org.freedesktop.UDisks service on the system message bus. One of the benefits of udisks is to automatically mount storage devices for users without super user privileges, making them accessible via a UUID.

Several problems have been attributed to udisks, like the following:
Problem mounting external USB drive in Ubuntu 12.04
http://askubuntu.com/questions/150813/problem-mounting-external-usb-drive-in-ubuntu-12-04
Secure remove of external USB-HDD produces error
https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/466575
Safely removing device generates error
https://bugs.freedesktop.org/show_bug.cgi?id=25657

The error message generated by udisks is always similar to:
Error detaching: helper exited with exit code 1: Detaching device /dev/sdc
USB device: /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-2)
SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory

So, the simplest solution is to disable previewable files. That solution works for both GNOME and KDE desktops. I think that solution works because udisks is polling the storage device it mounted, whenever there's a file change on the device the desktop is the last to be notified to reload the previewable contents of the modified file.

OpenStack+Ceph as Software-Defined Storage

SDS reduces the costs of the management of growing data stores by decoupling storage management from its hardware to allow for centralized management of cheaper, popular commodity hardware. The example SDS ecosystem uses open source software like OpenStack as a front-end interface on top of Ceph as the resource provider of a RADOS cluster of commodity solid-state drives. OpenStack provides user-friendly wrappers for accessing and modifying underlying Ceph storage. OpenStack comes in the form of distributed microservices with RESTful API's: Block (Cinder), File (Manila), Image (Glance), and Object (Swift). Each microservice can scale-out as a cluster of stand-alone services to accommodate the varying demands of high-growth storage. With OpenStack the underlying Ceph storage can address the block storage needs, file storage needs, image storage needs, and object storage needs of datacenters adopting open source as their new norm in an industry trend for high performace and high a

Network traffic monitoring in Linux with Python

You can investigate suspicious activity in your network traffic by collecting relevant machine data from your endpoint. You can use the machine data to create your own analysis. Before you start your investigation you will need to determine normal activity on your endpoint. Normal activity is the scope of functionality of the software on your endpoint during periods of low activity and high activity. You will need some kind of software that periodically collects specific machine data from your endpoint like my software developed in Python that's available for free download at https://github.com/davidbrennerjr/server-stats-collector Ingest one or more of the following machine data: Application specific logs from /var/log Raw dumps from sniffing at Layers 2-3 Raw dumps from /proc of kernel data structures Raw dumps of kernel routing tables General system-wide error messages from /var/log/syslog Do you

What are attack vectors?

In the generalized sense an attack vector is a path or means by which a hacker can gain unauthorized access to an endpoint in order to deliver a payload or to facilitate a crime. Attack vectors enable hackers to exploit vulnerabilities in the design of a network through the manipulation of applications and protocols. Attack vectors typically manipulate the software installed in the operating system of an endpoint. Examples of attack vectors are email attachments, pop-up windows, instant messages, service configurations, new software, and firewall modifications. Human ignorance or weaknesses could also be used for engineering attack vectors. For example, users could be fooled into weakening network defenses during times of remote collaboration and file sharing. Anti-virus software and firewalls do provide some defense or block attack vectors to some extent. Some of the mitigation measures used to thwart hackers usage of attack vectors include deep packet inspection, IP source trackers
