As one of the first steps to going public from being a Private Ltd company, we wanted a good BOD. Our MD Mr.Vivek Kedia had requested Prof Janat Shah, IIM Ahmedabad, to join our BOD. He is presently a professor at IIM Bangalore. He has also been the joint Managing Director at Jaydeep Engineering Ltd and the Production Planning Manager at Gujarat Steel Tubes Ltd. He has written a few papers (and co-written a few) which have been accepted for publication in IIMB Management Review, and International Journal of Production Economics amongst others.

Needless to say, we were skeptical about how we would explain the vast scope of our work
when we were told that Prof. Janat would come to our Kolkata office on June 09th to understand
Grmtech’s work, the different departments, and its people and culture. The different department
heads, with a few team members, explained their departments, their working, and their
aspirations to him. We were pleasantly surprised that so learned and experienced a man was so
down to earth, and asked questions whenever he did not understand anything that we explained.

Though he had come directly from the airport after seeing our Rajarhat site, and it being a long
day of discussions, he took a lively interest in understanding the working of Grmtech. Our work
was new to him, as he had never been associated with this industry before. We were not sure if
he would ultimately decide to be part of our BOD.

It is an achievement and honour for Grmtech that Prof Janat decided to be a part of Grmtech, from July 11th. As our MD rightly pointed out, Grmtech now has double the confidence to take on more challenges, as we have knowledge and approachability combined with a keen interest backing us now.

Thank you Sir for deciding to be a part of us.

I have 150 extensions in my asterisk-freepbx setup, which are broadly divided into following two classes :-

1. Record Incoming Call On Demand. Record Outgoing Call On Demand
   Extensions in this class:  8001, 8002, 8003, 8004, 8005 (total 5 in number)
2. Record All Incoming Call. Record All Outgoing Call
   Extensions in this class:  9001, 9002, … , 9145 (total 145 in number)

To avoid manual configuration of each extension, I had taken following steps:-

1. Execute following queries on asterisk database (mysql):
   UPDATE asterisk.users SET recording='out=Adhoc|in=Adhoc' WHERE extension IN (8001, 8002, 8003, 8004, 8005)
UPDATE asterisk.users SET recording='out=Always|in=Always' WHERE extension >= 9001 AND extension <= 9145

   The above queries updates the recording setting for extensions in database. The effect for extension 8001 may be seen at http://Your-Asterisk-Freepbx-Server-Domain-Name/admin/config.php?type=setup&display=extensions&extdisplay=8001

2. Open each extension page and press the submit button. Finally click “Apply Configuration Changes” so that the changes may be propagated in running asterisk server

We celebrated our 7th Foundation day today. We played some fun games and it was a real eventful evening.

At the datacenter the “IP KVM Virtual USB drive” wire was black and so were the power cables going into each of the servers.

We replaced the black wire with a red wire.

Now when we call remote hands to put the red wire labeled “IP KVM Virtual USB drive” to the USB port on one of the servers it would be so much easier,

On this server the operating system is installed on the 8GB compact flash card. So that the 10 hard drives of 1 TB each can be dedicated just to store the data in Raid1 and LVM on top of it.

Some of the things we are doing to install the OS on the flash card:
1. /var will be on the hard disk.
2. noatime for each of the partitions mounted on the flash card.

This article helped us quite a lot in optimizing our OS installation for the flash card:

Its surprising how many of us think this.

This is a must read for all grmtech colleagues:

The ISP has a black cable that is the input to the box made by “Mc Mans tel”. Here is a picture showing the manufacturer of the box.

Here is the picture showing the cable flow in and out of the “Mc Mans tel” box

From this black box made by McManstel there are two yellow eth5 cables that come out and go inside the Cisco Catalyst 2950 switch.

Cisco 2950 is a 24 port switch and on the far left of the following picture you will see the two output wires green and grey coming out of the cisco switch and going to my linux servers.

The probpem is:

1. Each port on the cisco 2950 switch is restricted to 512 Kbps of upload. I can get 12 Mbps of upload speed but for that I will need to run 24 parallel connections. I am hoping to get that 12Mbps of upload with just one port of the cisco 2950 switch instead of having to use all the 24 ports.

Wondering what is the solution ?
