interview with howie severino

Dear pluggers,

Here's my interview yesterday (March 25, Wed 9am) with Howie Severino
in his News To Go program, on my "No brownouts in summer" proposal.

If the government accepts the suggestion, I will need help from those
who run Web hosts to mirror the real-time display of the electricity
load curve.

If anyone among you knows Energy Sec. Petilla personally, I hope you can
help me convince him to try the idea out.

Hi Guys, 

What will be the best way to convert the url on nginx to all lowercase letters? We are using nginx+haproxy for load balancing.

Thank you.

Subject: Nmap Project Seeking Talented Programmers for Google Summer of Code

Hi folks.  I'm delighted to report that Nmap has been accepted by
Google to participate in this year's Summer of Code internship
program.  This innovative and extraordinarily generous program
provides $5,500 stipends to college and graduate students anywhere in
the world who spend the summer improving Nmap from home! They gain
valuable experience, get paid, strengthen their résumés, and write
code for millions of users.  We're one of the few orgs which have
participated every year since the program began, and we're quite
excited for our eleventh year!

Previous SoC students helped create the Nmap Scripting Engine, Zenmap
GUI, and the handy Ncat and Nping utilities.  Several of them became
top developers!  We're hoping for the same this year, but we need your
help to get the word out! If you know any college/grad students (or
are one) who might be interested, please point them to our project
ideas page:

You must hurry though, as applications are due this Friday at 19:00
UTC. We're absolutely forbidden from accepting any late applications.
You can start an application now though and improve it up until the

Applications can be submitted using the orange "Log in" button (under
"Students", not "Mentors and Administrators") at


PS: In Nmap news.  We were so busy coding that we forgot to announce
our Nmap 6.46 and 6.47 releases last year.  But they're available at .  And we're also working on a very big
release expected in the next month or two!

balance-alb question

Hello PLUGgers!

I have a small setup here in the office to test NIC bonding performance, specifically balance-alb or mode 6.  So I have the ff. machines:

1) SERVER: a desktop PC with two LAN ports (the mobo-built-in one plus a PCI-card one, both are Realtek chipset using the r8169 driver)

2) CLIENT-A: a desktop PC with just 1 LAN port - the built-in one.

3) CLIENT-B: a laptop with a built-in LAN port.

4) An 8-port unmanaged Cisco/Linksys switch.

All LAN ports in all machines are capable of 1GigE.

My goal is to see if the following will hold true:

a) Simultaneous transfer of a 32GB-sized file from both CLIENT-A and CLIENT-B to SERVER and getting a sustained transfer rate of 100MBps or so per client.

b) Simultaneous transfer of a 32GB-sized file from SERVER to both clients and getting a sustained transfer rate of 100MBps or so per client.

However, I can't seem to achieve either of the goal.

After a lot of googling around, "cat /proc/net/bonding/bond0" shows that while both ethernet ports are slaved, only one is active.

How do I make both slaves active?  My Google Fu is failing me on this.

Avoiding brownouts this summer (pls circulate widely)

Kindly circulate widely the piece below. We have to convince the
government and the media to get into the act. Thanks, Obet

How we can avoid brownouts
this summer without spending P450 million

by Roberto Verzola

[The author will launch his book Crossing Over: The Energy Transition
to Renewable Electricity this March 23, 2015, 9 a.m., at The Patio of
the UP Hotel, at the University of the Philippines, Diliman Campus. The
book was published by the Friedrich Ebert Stiftung of Germany. The
author may be reached at 0939-117-8999 or rverzola <at> See for details.]

The government is preparing for a 2015 power crisis. This crisis,
according to the testimony of Department of Energy Assistant Director
Irma Exconde before Congress last October 2014, is basically a
31-megawatt shortfall in supply for around two critical weeks in April. 

The government's solution is the Interruptible Load Program (ILP),
which will subsidize the expenses of large companies who have their own
generators, if these have to be run due to impending brownouts. The
estimated cost of the ILP program: around P450 million, charged to
electricity consumers. (See Jess Diaz, “ILP to cost power consumers
P450 M,” Philippine Star, Nov. 21, 2014.)1

March is now ending. Early mornings are still cool, but warming. The
truly hot summer can start anytime soon. We probably still have a week
or so before the crisis begins to be felt. 

Here is a simple way to prevent brownouts from occurring in Metro
Manila. Other electric utilities and cooperatives can use the approach
too, if at least one TV station covers their service area.

Imagine a screen that shows the available electricity supply in
megawatts (MW) as a horizontal line near the top of the screen. Imagine
the actual demand, also in MW,  tracing another graph on the same
screen─in realtime─from 7 a.m. to 11 p.m. The 24-hour load curve of
Meralco in shown in Figure 1.

Figure 1. Meralco's 24-hour load curve
(Insert figure here.)

This is not difficult to do. I have seen such displays in the offices
of suppliers of electricity. I am sure the Department of Energy can
produce such a display. 

Now, imagine the trace of the actual demand inching up, as we rise in
the morning, turn on some appliances and do our chores. Later in the
morning, the graph rises faster, as the people arrive in their offices,
turn on the lights, the airconditioning, and their computers, and as
factories and workplaces start up machines and other electrical
equipment. As the sun rises higher in the sky, more aircons and
electric fans are turned on; aircons work harder.

The demand curve is now approaching the horizontal supply curve. The
drama is building up.

Now, imagine television stations broadcasting the same screen, and the
Secretary of Energy─or the President himself─explaining on TV that each
individual can do something to prevent a brownout. They only need to
turn off some of their less important electrical loads: lights in
unused rooms, along corridors; one of three electric fans, postponing
ironing to off-peak hours, and so on. Some will surely respond,
especially if a prior media build up had been orchestrated earlier. One
million responses─each turning off a 40-watt or so load (one
fluorescent or incandescent lamp, one electric fan, or one computer)─is
more than enough to cover the 31-MW shortfall.

As the responses come in, the demand curve takes a noticeably less
steep path, but it keeps approaching the supply line. The tension is
becoming almost unbearable. On radio and TV, the Secretary sends out
another desperate appeal. Seeing that their actions did have some
effect on the curve, people will respond some more, and urge others to
act too. A critical mass of people now realize that it is better turn
off some appliances on your own, than lose all power. Text messages
fly, urging participation.

Watching the demand curve now feels like watching, live on TV, a
typhoon that is about to hit. but it is also swerving, thanks to
people's earlier responses. Thus, more will be encouraged to join in,
or to do more. It becomes a challenge, a race against time, or─if you
will─a game: do we win or do we lose?

If we win, one can surely imagine a collective cheer in every home and
office watching the screen, as if Pacquiao had just scored a knockdown.
But this time, it is everyone's victory.

If we lose, a brownout happens somewhere in the grid, as the system
sheds some load to avoid overheating the generating plants. One can
imagine hearing a collective sigh throughout the island. But with some
loads shed off, the demand will drop below the supply line again; we
are back in the game!

Imagine doing this everyday over a two-week period, as we collectively
struggle to spare the country from brownouts by pressing one switch and
then another, as if we were playing an online game. It will be the
greatest drama of the summer break.

With a more sophisticated display, we can make the “game” more
interesting (though this is not absolutely necessary). 
We can split the grid into four sectors, and split the screen into four
too, each quarter of the screen showing the demand curve and supply
line for each sector. Only those sectors that fail to turn off enough
loads get the brownouts. Now it becomes a contest between sectors too.
But everyone can win, if they can, collectively as a sector, manage to
swerve away from the supply line without hitting it. 

There is no way this won't work! This can become our national game
every summer.

By the way, this approach is called demand-side management (DSM). The
secret here is instant feedback. People can see right away the results
of their collective act. If you can see that what you are doing
matters, you are bound to do more of it. 

Remember: all this needs is for the Department of Energy to set up the
screen and the media to broadcast it. The public will do the rest. We
will because we do not want to be billed that P450 million .

book launching

This is a little off-topic, but maybe those who are interested in
leading-edge technologies may be interested. This is also the only list
I know where I can reach my old IT friends.

ELECTRICITY tomorrow Monday, 9-12am at the Patio of UP Hotel in UP

Those who are interested in renewable energy and rooftop solar are
welcome to drop by, or to stay and listen to my speech, and the
subsequent exchanges.

In the book I compared the grid to a emerging internet of electricity
providers and users, of entities which may sell electricity some of the
time and buy electricity at other times. I also look at the emerging
conflict between client/server and peer-to-peer models on the grid.

The full-text PDF file may be downloaded on the Web by the way, just
google the title.

Apache Virtual Web Hosting Security


I have a virtual web hosting setup in which the web server mounts the "web page" folders (html/cgi-bin) folders via NFS. Each virtual host has its own set of linux users / group, but the file permissions of the html / scripts are world readable / world executable as Apache is running non root. Is there a way to ensure file system security such as virtual host users cannot execute/view other virtual hosts files? Example: accounting people cannot view files created by engineering.

The following are the constraints that cannot be changed by me:
* Web server running under RedHat using Apache
* web page folders are on an NFS drive

Can security be implemented using ACL (over NFS)? This is uncharted waters for me. We are planning to use Apache MPM ITK ( Are there other alternatives (preferably without the need to install 3rd party software).
