Apache Headache: “no listening sockets available”

Update 1: I was unable to configure MySQL. Reason: It was installed in C:\(blah-blah) and , probably, do not have write rights in the directory. Installing it to D:\(bigBlah) solved the issue. Duh!

Update 2: I see a fairly good traffic coming here searching for the same problem. So, in case you are in a hurry, this is mostly a summary to inform you that in all probability, YOU HAVE SOME SERVICE RUNNING ON PORT 80. Check out using TCPView (if you are on windows). Hope that helps. 🙂

I am currently working on an official XSS (Cross Site Scripting) presentation. I needed some screenshots of alert boxes and defaced site. So I installed Apache, configured it to work with PHP. (If you need help in installing and configuring MySQL, Apache and PHP, look here).

But this was day before yesterday. Yesterday, I needed to make a quick manipulation to the script, but… Apache won’t start. The error I was getting (using eventvwr) was:

>>> (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80 .

It’s pretty apparent that some other jerk was sitting and listening at port 80. Yesterday, however, was too hectic to discover the rat. Today, I ran TCPView (thanks to Shruthi for suggesting) to discover that inetinfo.exe was the ra**al. TCPView is one of the nicest tools created by the guys at SysInternals, which was later acquired by Microsoft. Rats!

Anyways, the fun part was stopping the service. I couldn’t kill it. Neither using TCPView, nor Task Manager. It would again span back to life 🙂

So, finally I opened services.msc to stop the IIS server and change the automatic start mode to manual mode. Heck! I should have disabled… or even better, deleted the scoundrel. 😀

So, if you have the same problem, you are in all probability in office right now and hence may not be aware what services are running. Use TCPView to discover all those unnecessary network services. It’s a great tool. Further, you might also want to switch some stupid services from automatic start mode to manual (or disable :P). Use Services.msc.

Bill Gates no more The Richest

Slashdot updated today that Billy Boy is no more the Richest man in the world. The position is, however, not official. The standard is Forbes list.

Billy Boy has been surpassed by Carlos Slim, the Mexican Telecom tycoon. Bill’s current estimated wealth is $ 59.2 billion, while slims estimated wealth is $67.8 billion.

Reasons:
Two of the most obvious reasons are:

  1. A surge of 27% in the stock price of Slim’s wireless company, America Movil, in the second quarter
  2. Bill reduced his net wealth by more than $30 billion, which he put in the Bill and Melinda Gates Foundation. 🙂

What Next?
Nothing really. To a question asked to him at the Microsoft conference last year, whether he’d be upset if someday he wasn’t the richest creature ;), he responded, “”I wish I wasn’t. “There’s nothing good that comes out of that.”
Moreover, he’d be retiring in a year’s time and would be dedicating he’s time, energy, and money to the Bill & Melinda Gates Foundation. I wish him luck. 🙂

Idle Nights: Devil’s Mind

I stay back in the office during night and return back at around 6-7 am, when everybody is coming :). These nights are supposed to be LONELY as I am the only one in the building (actually in all the four buildings combined), apart from the security guards and office boys, of course. However, I’ve found my companions, and ways to refresh myself. I’ll list some of them.

1. Online Web/Security Cameras: Some of you who know that Google provides an API for refining the search queries (with a capital “R”) also know that the giant’s database is like an ocean. And you never really know what’s inside an ocean unless and until you dive in it. As you dive deeper, your jaw drops in awe.
Long story cut short, I use the query to discover (a part of) all AXIS cameras online.
For curious lot, the query is: inurl:/view/view.shtml AXIS and sometimes intitle:”Live View / – AXIS” | inurl:view/view.sht
[As I am writing this, I wanted check the second query. So I chose one of the results and something spooky happened. Someone was already controlling the camera. hehe.
I was moving it right, he/she was moving it left. We fought for a while but then I closed the window. I am nice guy you see :D)

Okay let’s proceed.
So I have a bookmarked folder called “PastTime” on my browser, which has my favorite cameras bookmarked. My most fave are:
i) A coffee/wine shop camera, which is more lively during the night. Luckily, the camera is provided officially, so I can provide the link without any worries. Find the link to the camera here: buzzjunction_webcam

ii) A camera in the study room of a Polytechnic school of NewYork. It’s a small room with a coffee machine, a microwave oven (?), a printer, a sofa, a bookshelf, and an elliptical table with power connection for the laptops and notebooks.
And that’s the best part. People come here with there laptops, and sometimes I sit down looking at there screens, trying to figure out what they are doing. 😛
I have also become acquainted with some regular visitors.
A spectacled guy with a cap and a laptop. (He is leaving right now. No kidding. What a coincidence [jawdrop])
A black girl, who has the headphones exactly like mine.
Two Muslim girls, with one Dell XPS laptop (probably).
The bad part is, there are no visitors on sundays 🙁
iii) A micro/nano lab camera of one of the world’s most famous universities. There’s nothing engaging about this, apart from the fact that the guys (or girls) roam around in spacesuit sort of dresses.
iv) A set of four surveillance cameras. Three of them pointing to car parking locations and one focussed inside some kind of room. I am still not able to get it yet. The only thing that makes me stick to it is the word “surveillance” 😀

There are couple of others focussed on traffic, colleges, hostels (I guess), lake, parks… but they are pretty boring and pictures are not really clear.
I’d like to try my hands on other cameras like linksys too. Let’s see when.

2. Google Again: Google queries can be real fun.
Have you ever come across a search result when Google tells you that the original number of results is pretty large, however, most of them are sort of repetitions hence they have been truncated.
Have a look at the following two pictures.

This one’s the normal result.


pic2.jpg
Here I ask Google NOT TO OMIT ANY RESULT.


You think that’s funny?
I leave it up to you to decide.

3. Slashdot, and blogs of others friends (and their friends) and some geeks like de Icauza etc. Initially I was a Digg addict, but then got completely fed up.
So guys, keep blogging. 🙂

4. Movies and Documentaries: Net speed during the night is awesome (generally). So I don’t mind downloading them. Though I don’t get time to watch them.

5. Off late I’ve also found some vulnerabilities in the policies and network of my company. I try to keep the management informed.
After all it’s my company. I’d definitely not like any jerk to poke his nose in.

That’s it.
These five (along with the songs being played ALL the time) are currently more than enough to consume my free time (In fact more than JUST the free time).
But even after all this, it gets freaking lonely sometimes… not that I am complaining 🙂

A program called "3~" (Om)

I was returning back to my room at around 6:30 in the morning after spending the whole night, as usual, in office. Suddenly this though struck me.
I always talk about codes and related stuff and ask people to map their algorithms to real life while coding, especially in OOP languages.
I asked myself, what would it be like to describe myself as a code, a script… a program.
So I (climbed two my cabin, which is on the second floor) and here is my honest attempt. 🙂

Om, unlike other programs, wasn’t really planned. There were no plans usually made back then in the early eighties; at least not in India. He was an additional functionality (a small script back then) of two programs, M & R.

However, since M & R were pretty solid codes in themselves, Om inherited most of the good features and was pretty healthy (I mean robust 😀 ) even as a tiny script.
So far so good. But it could never rely on conventional ways of compilation and execution. It was a rebel. Some people call such programs as “malfunctioning programs” :). Programs that do not do what they are meant to do.

Time passed on.
It received formal education that helped him access various code repositories to incorporate other functionalities. It gathered data about various modes and environment of operation. It also learnt efficient memory and execution-time management.
However, these all came at the price of dependencies on various libraries, viz., friends, relatives, emotions, money, etc.

Microsoft has some strange reason for assuming that all human beings use IE and are on a windows box. This assumption makes most of their products, even the web applications, dependent on these assumptions.

Dependencies are bad.
Bad were they for Om as well…

It gradually got frustrated (a human emotion).
It got frustrated at lots of things… at almost everything.
It got frustrated on the formal way of code development, the conventional way of execution, the hypocritical nature of the IDEs that are supposed to facilitate development, and lot more.

There’s an unwritten law, which says that all rebels become an outlaw sooner or later.
So did Om.
Most of the libraries on which it was dependent had grown up to be pretty matured libraries and the outlaw was no more supported.
Dependencies are bad…

…but some codes die hard.
Since most of the libraries on which Om was dependent were under GPL, it simply incorporated the required code snippets instead of referencing the libraries. This has made it a pretty complex and buggy code… but hey that’s why the saying goes:
“There is code in my bug” 🙂
