Mettle CM is deployed in most demanding of situations a call center solutions can run in: mission-critical. So it has proved how good a solution it is–in terms of reliability, scalability, performance and flexibility. What next every organisation will look for is the information on how their call centers are being used. This helps an organisation to fine tune, optimise and improve their resources towards business benefits.

Mettle CM registers 23 parameters for every single call it handles with Telecom-grade accuracy. This gives a database for you look at your call center at any perspective you want. This calls for an enterprise-grade Business Intelligence System.

Pentaho is a business intelligent project which provides enterprise-grade reporting, analysis, dashboard, data mining and workflow capabilities that help organisations operate more efficiently and effectively. Pentaho has been ranked number 1 in open source Business Intelligence.

Mettle CM could not find a better component to provide business intelligence. Integration of Pentaho with Mettle CM is just over and it’s ready for deployment.

Mumbai-based Hathway Datacom Pvt. Ltd. selects the anti-spam solution from Linuxense. Hathway is the largest broadband provider and it provides service in eleven cities across India.

Their evaluation was a rigorous, month-long procedure to check out whether the solution is capable of achieving near-zero spam rate in their customer Email boxes. That too without adding any latency to the delivery time.

Linuxense designed a Linux-based anti-spam filtering solution which is a multi-server scalable cluster. It is designed to stand heavy spam-runs and protects the mail servers from being overwhelmed by such traffic.

Hathway is the second ISP to avail of this solution from Linuxense.

Linuxense started offering Asterisk-based call center solutions under the brand name Mettle™ Contact Manager to service providers and institutions which host in-house call centers for sales and customer support.

Much awaited GuardianConnect is out. All at Linuxense have been working on this project for quite a while now. Now it has been installed and running at Christ Nagar English Medium School, Trivandrum and Sainik School Kazhakootam.

GuardianConnect™ is a device that filters the Internet for content which is inappropriate for children. This device is meant for schools, hostels, libraries and other places where children use the Internet.

GuardianConnect is a rugged table-top box designed to handle up to 2 mbps of Internet traffic. And it does not put any cap on number of users or Desktops neither there is no licences to renew. GuardianConnect (also referred as Guardian Connect) is a one-time investment.

Linuxense has been decided to provide GuardianConnect with one year comprehensive warranty and support.

The Hindu daily referred it as the “Guardian of the young Net surfer”.

Several schools have shown interested in GuardianConnect.

Initially it sounded amusing when we got a call from C-DIT seeking expertise to set up live streaming of Chief Minister’s office. But we took it seriously because of two reasons. First: we were planning to try out VLC in a real-world scenario for quite a while. Secondly, we were told that a couple of MNC consultancy firms declared that this is an impossible task. And we accepted the work order from C-DIT.

The Components
It was difficult to get a camera with remote-controlled tilt and pan facility in sub-30K range. We finally procured a D-Link DCS 5300W. Being an experimental setup it is we asked for just two desktop machines; one for connecting the camera which is inside the secretariat LAN. And the other to act as a “slave” server which handled the Internet traffic.

Secretariat was linked with a 2-mbps leased line from BSNL. Though that was very much inadequte a bandwidth, we decided to hook up the streaming server to this link as there was no other option.

Public Response
Whether is it a stupid idea or not; public welcomed it. The news was all over the media. Within a few minutes after the inauguration the traffic overwhelmed the 2 mbps link. People were calling (even from outside India) and complained that they could not connect to it.

Is It Really Relevant?
The answer is: it depends. Because, you and I may not be watching this stream on a regular day unless we are terribly bored and have nothing else to do. But, all of us will tune in if some crucial thing happens in CM’s office; an important meeting, a conference, or a meeting with a foreign delegate. Or anything at CM’ office which particularly interests us. So, it makes sense.

Now, let’s look at it from CM’s side. For him it is like having his own television channel! He can say whatever he wants to the public face-to-face without depending the media (which are known to report preferentially); here there is no one in between –just CM on one side of the Internet and the public on the other.

Technology makes things do-able in very cost-effective way these days which is really cool. And the good point is that our CM is wise to take advantage of it.

Linuxense is stepping into hardware-based IT Infrastructure Management Solutions business under the brand name Mettle.

Linux can play several other roles than serving as a desktop OS or as a sever OS. It can function as a router, firewall and many more. Given enough hardware resources it can out-perform several commercially available proprietary hardware solutions.

So far such capabilities of Linux remained with some do-it-yourself administrators and hobbyists. Now, you can avail of these capabilities in the Mettle platform and that too can be purpose-built taking advantage of the flexibility of the Linux operating system.

Unlike proprietary hardware platforms, Mettle devices do not become obsolete unless you need a hardware upgrade. This is because of the fact that it runs on Linux. Also, in off-the-shelf proprietary devices it is unavoidable to pay for features which you would never use and at the same time it may not cater your requirements completely. But Mettle avoids both; thanks to the flexibility of Linux and Open Source software.

Says Anil Kumar K., Vice President (Engineering), “If you buy proprietary hardware solutions rather than a Mettle device you would end up buying a dozen of them to get the same set of functions yet of less reliability due to the external interconnections of those boxes.'’ Considering the set of functionalities it offers, Mettle devices are very much cost-effective too compared to the money otherwise you would need to spend on a number of proprietary devices.

Linuxense provides both value-for-money solutions aimed at small and medium enterprises and robust, high availability (HA), high performance solutions designed for large enterprise, ISPs and service provides.

None broke into the server which was on the Net for 96 hours. Kudos to Adamantix!

See details at http://www.linuxense.com/challenge

At the end of 48th hour we have released a shell account with the login name ROT13ed. It didn’t take more than a couple of minutes for the first person to login! But there were several contestants who complained about a login account which “just doesn’t work'’.

Most of the attempts had stack-smash as the basic technique which Pax is good at. But there was a Pax privilege elevation bug to which Adamantix 1.0.4 was susceptible. See http://seclists.org/lists/fulldisclosure/2005/Mar/0211.html for more details. But the first exploit wasn’t out till the end of 96 hours (though the Kernel used was not fully susceptible)

Packet capture dump is being circulated via Bittorrent and had several downloads so far.

We thank Asianet Satellite communications for providing us bandwidth.

This break-in challenge was unique in a sense that this was the first time an Open source product was put under such a test. Normally companies do this to show off their own product’s capability.

Linuxense is holding a Linux Server Break-in Challenge. We set up a hardened server, connecting it to the Internet and inviting those who are “crackers'’ at heart to break-in to it.

This event does not offer any prize money; and we are not planning to ship the server to the winner. But if you break in you you get a permanent reference in our challenge page –this is a “No Prizes; Just Applause'’ affair.

This is a regular Linux server with its traffic routed through a bridge to sniff the packets passing through and to limit outbound traffic. This bridge (yet another Linux box) will be logging all the packets passing through. This data will be made available to the participants –learn what others did it and do forensic analysis.

This server will become available on the net by 2 AM IST, 9 March 2005 and will be there for 96 hours or till you take it down. See the details on our web site.

Watch this space for updates on the event. Good luck!

Linuxense is shifting to a new office in Poojapura. We will be functioning on the third floor of “Koipurathu Buildings” located on Karamana road (there is an SBT ATM functioning in this building). Shifting process will be completed by Saturday 18.

All of us are happy and sad at the same time in this occassion. We are excited because the new place has more amenities and features. We are sad because we are leaving an one-of-a-kind, 75 year old, huge building surrounded by fruits and trees and flowers which kept us busy while we were not coding.

We are thankful to the landlord, Krishna G.S. and CVR for arranging the present place for us. Linuxense has been functioning out of this place for the past two years. We also thank CVR’s parents and brother Rajaram for taking care of us during their stay here in this building.
