It will be better with Static IP as per my experience in Panvel. I am not
sure about other places.

Guys i have a question and need some one to answer .The question is as
follows.
1 ) I have a multiple CPU machine say with 4 CPU's .Now I have 3 instances
of an application running on the machine and the OS takes care of the CPU
schedule by default.I want to know is there a way in Linux or any other UNIX
wherein I can allocate 1 complete CPU to 1 instance of this application.

To Love The Penguin(aka TUX) You Need To Be As Faithful As A Puppy
Hi,
Suppose I had a 150 TB / 74 CPU dual quad Intel on Rental.Connected by
dual Ethernet of 1.0 Gigabits second.
Would it help advance research in India ? Would new pharma drugs come
out of it ?
Should it be given to students say at the rental of Rs 500 a month/Rs
1000 a month (they can easily afford that from their UGC scholarships
---- what max can I charge for it).
In 2 years time it wouldn't cost much.
And it would generate tonnes of parallel programmers.
Currently, would it be good for high-tech research all over
India/third world countries all over the world ---------------- can
such a super-computer be used for destruction/ I say NOT.
This would spur tremendous research in the next 10 years as
Universities churn out people over a Beowulf cluster.

I have been using it for many months now at Kharghar. The plan I have
chosen gives me 25 to 30 kBytes of download and upload speed.
There is an outdoor antenna which is powered over ethernet. It is placed
on my rooftop. In my case, I am using a 4 port router and configured it
to obtain WAN IP address over DHCP. Using NAT, I can share this
connection to multiple PCs at home. For user-authentication, they
provide a web interface which work beautifully on Firefox. Unless you
authenticate, all web-requests are re-directed to their authentication
server.
Earlier they used to sell 2mbps connections, but when I approached
them many months ago, they told me that that scheme had been
terminated. Then I had been promised 300kbps bandwidth. For
unlimited data transfer, I pay around Rs.1150/- per month(including
taxes). This connection though expensive, is reliable most of the time.
> What I want to know is - 1) compatibility with Linux Boxes
If you configure your Linux machine to obtain IP address on its
network interface via DHCP, you don't need a router and can use
any GNU/Linux distro.

During rains too I have used this system without problems. But I can't
confirm whether it works reliably over an extended period of time during
heavy rains. I am afraid of toasting my router in lightening, and hence
keep it disconnected from the wire during heavy rains. I have faced no
major problems except some irritants (see below) which I can live with.
At least their service is hundred times better than Sify's. The experience
with Sify and their local cablewalla contacts were pathetic, to put it mildly.

This is a major advantage compared to any wired connection. Especially
if you provide services to your clients in real-time, something like this
is necessary.
Now the irritants with Reliance Wi-max:
1. Their DHCP connection is not very reliable, at least on Linux machines.
The strangest part is, whenever I use a Windows machine, I get an IP
allocated to me immediately. But it takes about 5 to 10 minutes to get an
IP on my Linux box (it used to run SuSE 10). Even on my router, I have to
carry out following procedures in exact order to get an IP fast:
a. Switch-on the power to antenna.
b. Wait for two minutes.
c. Switch-on the power to the router.
d. Wait for at least one minute.
e. Check whether IP is allocated or not. Most of the time you get an
IP. But if you fail to get it, go to web based admin console of the
router and click on buttons meant to renew DHCP release and/or
re-new. Then you get the IP and the connection remains rock solid
for the rest of the session.
2. On some rare occasions the connection fails after some usage.
If that happens, then there is no way I can get authenticated again
immediately. Whenever I re-try authentication by submitting the
web form, I get the message of authentication failure. This problem
gets rectified automatically after half-an hour. It seems they have
placed some mechanisms to prevent password-guessing-attacks.

Thanks for the info. What was the issue with DHCP service? Do you
recommend Static IP?

i have used reliance wimax with centos linux in panvel. it works nice.
reliability is also good.
i felt it is cheaper also. i have taken static ip from reliance as i got
some issue with their dhcp service on linux.
now it is working fine.

I empathetic to your anguish and frustration with the existing system.
And those "jokers" are elected represantatives of you. You may have
either directly elected them by voting for them or indirectly elected
them by NOT VOTING for them. Let us start by owning our own
responsibility.

Yes, though it is OT, we users of Free Software and Technology also
WANT and NEED Freedom in other areas of our life too. Discussing this
on this or any other technology related mailing list is not totally
irrelevant. Slashdot also has sections for Politics and YRO too!
I have changed the subject line but kept the thread as is.

Hello Guys and Gals,
We will possibly have a ILUG-BOM Dec 2008 meet on 21st or 28th.
I know many of you are surely working on cool FOSS Stuff and you are
always eager to share your experiences. :-)
I would like to invite you to speak on the topic of your choice.
Please let me know what would you to speak on and I will work with you
to finalize the topic.
BTW, we already have one Talk from Prashant Shah. So we need one or
