Red Hat Enterprise Linux 6 – Red Hat Enterprise Linux 6.4 – is now available.
Key new features and enhancement details include:
Identity Management
Identity Management
- System Security Services Daemon (SSSD) enhancements improve the interoperability experience with [Microsoft Active Directory] by providing centralized identity access control for Linux/Unix clients in a heterogeneous environment.
File system
- pNFS (Parallel NFS) client (file layout only) remains in technology preview, however now delivers performance improvements with the addition of Direct I/O for faster data access. This drives particular performance benefits for I/O intensive use cases including database workloads.
Virtualization
- Red Hat Enterprise Linux 6 now includes the Microsoft Hyper-V Linux drivers, which were recently accepted by the upstream Linux community, improving the overall performance of Red Hat Enterprise Linux 6 as a guest on Microsoft Hyper-V.
- Installation support for VMware and Microsoft Hyper-V para-virtualization drivers. This new feature enhances the user deployment experience of Red Hat Enterprise Linux as a guest in either of these virtualization environments.
- In this release, KVM virtualization virtio-scsi support, a new industry storage architecture, provides industry leading storage stack scalability.
Management
- The use of swap functionality over NFS enables more efficient read/write tradeoffs between local system memory and remote disks. This capability increases performance in very large, disk-less server farms seen in ISP and Web hosting environments.
- Enhancement in c-groups delivers the ability to migrate multi-threaded applications without errors.
- Optimized perf tool for the latest Intel processors
Storage
- New system log features identify mapping from block device name to physical device identifier – allowing an administrator to easily locate specific devices as needed.
Productivity Tools
- Microsoft interoperability improvements with Microsoft Exchange and calendar support in Evolution. Productivity functions, such as calendar support with alarm notification and meeting scheduling is improved.
- Customers such as animation studios and graphic design houses now have support for the newer Wacom tablets.

How to Turn Your Ubuntu Laptop into a Wireless Access Point
If you have a single wired Internet connection – say, in a hotel room – you can create an ad-hoc wireless network with Ubuntu and share the Internet connection among multiple devices. Ubuntu includes an easy, graphical setup tool.
Unfortunately, there are some limitations. Some devices may not support ad-hoc wireless networks and Ubuntu can only create wireless hotspots with weak WEP encryption, not strong WPA encryption.
Setup
To get started, click the gear icon on the panel and select System Settings.
Select the Network control panel in Ubuntu’s System Settings window. You can also set up a wireless hotspot by clicking the network menu and selecting Edit Network Connections, but that setup process is more complicated.
If you want to share an Internet connection wirelessly, you’ll have to connect to it with a wired connection. You can’t share a Wi-Fi network – when you create a Wi-Fi hotspot, you’ll be disconnected from your current wireless network.
To create a hotspot, select the Wireless network option and click the Use as Hotspot button at the bottom of the window.
You’ll be disconnected from your existing network. You can disable the hotspot later by clicking the Stop Hotspot button in this window or by selecting another wireless network from the network menu on Ubuntu’s panel.
After you click Create Hotspot, you’ll see an notification pop up that indicates your laptop’s wireless radio is now being used as an ad-hoc access point. You should be able to connect from other devices using the default network name – “ubuntu” – and the security key displayed in the Network window. However, you can also click the Options button to customize your wireless hotspot.
From the wireless tab, you can set a custom name for your wireless network using the SSID field. You can also modify other wireless settings from here. The Connect Automatically check box should allow you to use the hotspot as your default wireless network – when you start your computer, Ubuntu will create the hotspot instead of connecting to an existing wireless network.
From the Wireless Security tab, you can change your security key and method. Unfortunately, WPA encryption does not appear to be an option here, so you’ll have to stick with the weaker WEP encryption.
The “Shared to other computers” option on the IPv4 Settings tab tells Ubuntu to share your Internet connection with other computers connected to the hotspot.
Even if you don’t have a wireless Internet connection available to share, you can network computers together and communicate between them – for example, to share files.

Google launches free SMS service for Gmail in India
Search giant Google has started rolling out free SMS for its free email service Gmail and paid email service Google Apps customers in India. The service allows users to send SMSes to mobile phones from chat windows. Users have to add mobile numbers of their contacts in the email address book and they are set.
The service starts with 50 SMS cr
The service starts with 50 SMS cr
edits for each user, every sent SMS costing one credit. Every reply received adds on 5 credits subject to the maximum level being 50 SMS at any given time. There is no official statement from Google on the launch of this service, however the service has gone live this evening in the chat windows of many users.
Google is rolling out the service in partnership with cellular operators, which means they would share revenue with Google out of SMSes users on their network send. It specifies a way to buy more SMS credits.
"You can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your SMS credit is increased by five. Effectively, you're buying more messages by paying your phone company for these outgoing messages," it writes on its chat help portal.
The service currently supports eight cellular operators including Aircel, Idea, Loop Mobile, MTS, Reliance, Tata DoCoMo, Tata Indicom and some circles of Vodafone. BSNL, MTNL and Airtel are not supported yet.
The SMSes sent from Gmail chat are delivered to mobile phones while replies from the mobile phone come into the chat window. For the mobile phone user, the reply is charged at local SMS rate as per her/his normal billing plan.
If no replies are received to any of the 50 SMSs sent and the credit balance come down to zero, Google says, "...it will increase back up to one 24 hours later. So, you won't ever be locked out of the system."
