Google Cloud is finally here

Amazon gets some competition, and customers should see some relief, unless Google withdraws commitment on these products after a few years of trying (like it often does now!)

send email by R

For automated report delivery I have often used send email options in BASE SAS. For R, for scheduling tasks and sending me automated mails on completion of tasks I have two R options and 1 Windows OS scheduling option. Note red font denotes the parameters that should be changed. Anything else should NOT be changed.

Option 1-

Use the mail package at

http://cran.r-project.org/web/packages/mail/mail.pdf

> library(mail)

Attaching package: ‘mail’

The following object(s) are masked from ‘package:sendmailR’:

sendmail

>
> sendmail(“ohri2007@gmail.com“, subject=”Notification from R“,message=“Calculation finished!”, password=”rmail”)
[1] “Message was sent to ohri2007@gmail.com! You have 19 messages left.”

Disadvantage- Only 20 email messages by IP address per day. (but thats ok!)

Option 2-

use sendmailR package at http://cran.r-project.org/web/packages/sendmailR/sendmailR.pdf

install.packages()
library(sendmailR)
from <- sprintf(“<sendmailR@%s>”, Sys.info()[4])
to <- “<ohri2007@gmail.com>”
subject <- “Hello from R”
body <- list(“It works!”, mime_part(iris))
sendmail(from, to, subject, body,control=list(smtpServer=”ASPMX.L.GOOGLE.COM”))

Disadvantage-This worked when I used the Amazon Cloud using the BioConductor AMI (for free 2 hours) at http://www.bioconductor.org/help/cloud/

It did NOT work when I tried it use it from my Windows 7 Home Premium PC from my Indian ISP (!!) .

It gave me this error

or in wait_for(250) :
SMTP Error: 5.7.1 [180.215.172.252] The IP you’re using to send mail is not authorized

 

PAUSE–

ps Why do this (send email by R)?

Note you can add either of the two programs of the end of the code that you want to be notified automatically. (like daily tasks)

This is mostly done for repeated business analytics tasks (like reports and analysis that need to be run at specific periods of time)

pps- What else can I do with this?

Can be modified to include sms or tweets  or even blog by email by modifying the   “to”  location appropriately.

3) Using Windows Task Scheduler to run R codes automatically (either the above)

or just sending an email

got to Start>  All Programs > Accessories >System Tools > Task Scheduler ( or by default C:Windowssystem32taskschd.msc)

Create a basic task

Now you can use this to run your daily/or scheduled R code  or you can send yourself email as well.

and modify the parameters- note the SMTP server (you can use the ones for google in example 2 at ASPMX.L.GOOGLE.COM)

and check if it works!

Using Cloud Computing for Hacking

This is not about hacking the cloud. Instead this is about using the cloud to hack

 

Some articles last year wrote on how hackers used Amazon Ec2 for hacking/ddos attacks.

http://www.pcworld.com/businesscenter/article/216434/cloud_computing_used_to_hack_wireless_passwords.html

Roth claims that a typical wireless password can be guessed by EC2 and his software in about six minutes. He proved this by hacking networks in the area where he lives. The type of EC2 computers used in the attack costs 28 cents per minute, so $1.68 is all it could take to lay open a wireless network.

and

http://www.bloomberg.com/news/2011-05-15/sony-attack-shows-amazon-s-cloud-service-lures-hackers-at-pennies-an-hour.html

Cloud services are also attractive for hackers because the use of multiple servers can facilitate tasks such as cracking passwords, said Ray Valdes, an analyst at Gartner Inc. Amazon could improve measures to weed out bogus accounts, he said.

How to find out people who are spamming you

Step 1-

We assume you have Gmail. If you dont have Gmail, you deserve the Spam

You click -show original on the drop down in the spammy message

 

you see a lot of mumbo jumbo

(or you just pick the IP addresses from comment spam)

Step 2-

You pick the IP addresses from the mumbo jumbo above (called headers )

http://en.wikipedia.org/wiki/IP_address

An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer networkthat uses the Internet Protocol for communication.[1] An IP address serves two principal functions: host or network interface identification and locationaddressing

Step 3-

You find out who has that IP address using arin

https://www.arin.net/

 

Step 4-

You put those IP addresses in your firewall for your computer

http://technet.microsoft.com/en-us/library/cc733090(v=ws.10).aspx

(or if you have a self-hosted blog using Website cpanel ip deny)

http://www.siteground.com/tutorials/cpanel/ip_deny_manager.htm

Step 5-

 

Communicate to that IP Address using IRC

http://en.wikipedia.org/wiki/Internet_Relay_Chat

Internet Relay Chat (IRC) is a protocol for real-time Internet text messaging (chat) or synchronous conferencing.[1] It is mainly designed for group communication in discussion forums, called channels,[2] but also allows one-to-one communication via private message[3] as well as chat and data transfer,[4] including file sharing.[5]

Cyber Cold War

I try to write on cyber conflict without getting into the politics of why someone is hacking someone else. I always get beaten by someone in the comments thread when I write on politics.

But recent events have forced me to update my usual “how-to” cyber conflict to “why” cyber conflict. This is because of a terrorist attack in my hometown Delhi.

(updated-

http://www.nytimes.com/2012/02/14/world/middleeast/israeli-embassy-officials-attacked-in-india-and-georgia.html?_r=1&hp

Iran allegedly tried  (as per Israel) to assassinate the wife of Israeli Defence Attache in Delhi using a magnetic bomb, India as she went to school to pick up her kids, somebody else put a grenade in Israeli embassy car in Georgia which was found in time. 

Based on reports , initial work suggests the bomb was much more sophisticated than local terrorists, but the terrorists seemed to have some local recce work done.

India has 0 history of antisemitism but this is the second time Israelis have been targeted since 26/11 Mumbai attacks. India buys 12 % of oil annually from Iran (and refuses to join the oil embargo called by US and Europe)

Cyber Conflict is less painful than conflict, which is inevitable as long as mankind exists. Also the Western hemisphere needs a moon shot (cyber conflict could be the Sputnik like moment) and with declining and aging populations but better technology, Western Hemisphere govts need cyber conflict as they are running out of humans to fight their wars. Eastern govt. are even more obnoxious in using children for conflict propaganda, and corruption.

Last week CIA.gov website went down

This week Iranian govt is allegedly blocking https traffic on eve of Annual Revolution Day (what a coincidence!)

 

Some resources to help Internet users in Iran (or maybe this could be a dummy test for the big one – hacking the great firewall of China)

News from Hacker News-

http://news.ycombinator.com/item?id=3575029

 

I’m writing this to report the serious troubles we have regarding accessing Internet in Iran at the moment. Since Thursday Iranian government has shutted down the https protocol which has caused almost all google services (gmail, and google.com itself) to become inaccessible. Almost all websites that reply on Google APIs (like wolfram alpha) won’t work. Accessing to any website that replies on https (just imaging how many websites use this protocol, from Arch Wiki to bank websites). Also accessing many proxies is also impossible. There are almost no official reports on this and with many websites and my email accounts restricted I can just confirm this based on my own and friends experience. I have just found one report here:

Iran Shut Down Gmail , Google , Yahoo and sites using “Https” Protocol

The reason for this horrible shutdown is that the Iranian regime celebrates 1979 Islamic revolution tomorrow.

I just wanted to let you guys know about this. If you have any solution regarding bypassing this restriction please help!

 

The boys at Tor think they can help-

but its not so elegant, as I prefer creating a  batch file rather than explain coding to newbies. 

this is still getting to better and easier interfaces

https://www.torproject.org/projects/obfsproxy-instructions.html.en

Obfsproxy Instructions

client torrc

Step 1: Install dependencies, obfsproxy, and Tor

 

You will need a C compiler (gcc), the autoconf and autotools build system, the git revision control system, pkg-config andlibtool, libevent-2 and its headers, and the development headers of OpenSSL.

On Debian testing or Ubuntu oneiric, you could do:
# apt-get install autoconf autotools-dev gcc git pkg-config libtool libevent-2.0-5 libevent-dev libevent-openssl-2.0-5 libssl-dev

If you’re on a more stable Linux, you can either try our experimental backport libevent2 debs or build libevent2 from source.

Clone obfsproxy from its git repository:
$ git clone https://git.torproject.org/obfsproxy.git
The above command should create and populate a directory named ‘obfsproxy’ in your current directory.

Compile obfsproxy:
$ cd obfsproxy
$ ./autogen.sh && ./configure && make

Optionally, as root install obfsproxy in your system:
# make install

If you prefer not to install obfsproxy as root, you can instead just modify the Transport lines in your torrc file (explained below) to point to your obfsproxy binary.

You will need Tor 0.2.3.11-alpha or later.

Step 2a: If you’re the client…

 

First, you need to learn the address of a bridge that supports obfsproxy. If you don’t know any, try asking a friend to set one up for you. Then the appropriate lines to your tor configuration file:

UseBridges 1
Bridge obfs2 128.31.0.34:1051
ClientTransportPlugin obfs2 exec /usr/local/bin/obfsproxy --managed

Don’t forget to replace 128.31.0.34:1051 with the IP address and port that the bridge’s obfsproxy is listening on.
 Congratulations! Your traffic should now be obfuscated by obfsproxy. You are done! You can now start using Tor.

For old fashioned tunnel creation under Seas of English Channel-

http://dag.wieers.com/howto/ssh-http-tunneling/

Tunneling SSH over HTTP(S)
This document explains how to set up an Apache server and SSH client to allow tunneling SSH over HTTP(S). This can be useful on restricted networks that either firewall everything except HTTP traffic (tcp/80,tcp/443) or require users to use a local (HTTP) proxy.
A lot of people asked why doing it like this if you can just make sshd listen on port 443. Well, that might work if your environment is not hardened like I have seen at several companies, but this setup has a few advantages.

  • You can proxy to anywhere (see the Proxy directive in Apache) based on names
  • You can proxy to any port you like (see the AllowCONNECT directive in Apache)
  • It works even when there is a layer-7 protocol firewall
  • If you enable proxytunnel ssl support, it is indistinguishable from real SSL traffic
  • You can come up with nice hostnames like ‘downloads.yourdomain.com’ and ‘pictures.yourdomain.com’ and for normal users these will look like normal websites when visited.
  • There are many possibilities for doing authentication further along the path
  • You can do proxy-bouncing to the n-th degree to mask where you’re coming from or going to (however this requires more changes to proxytunnel, currently I only added support for one remote proxy)
  • You do not have to dedicate an IP-address for sshd, you can still run an HTTPS site

How to learn to be a hacker easily

1) Are you sure. It is tough to be a hacker. And football players get all the attention.

2) Really? Read on

3) Read Hacker’s Code

http://muq.org/~cynbe/hackers-code.html

The Hacker’s Code

“A hacker of the Old Code.”

  • Hackers come and go, but a great hack is forever.
  • Public goods belong to the public.*
  • Software hoarding is evil.
    Software does the greatest good given to the greatest number.
  • Don’t be evil.
  • Sourceless software sucks.
  • People have rights.
    Organizations live on sufferance.
  • Governments are organizations.
  • If it is wrong when citizens do it,
    it is wrong when governments do it.
  • Information wants to be free.
    Information deserves to be free.
  • Being legal doesn’t make it right.
  • Being illegal doesn’t make it wrong.
  • Subverting tyranny is the highest duty.
  • Trust your technolust!

4) Read How to be a hacker by

Eric Steven Raymond

http://www.catb.org/~esr/faqs/hacker-howto.html

or just get the Hacker Attitude

The Hacker Attitude

1. The world is full of fascinating problems waiting to be solved.
2. No problem should ever have to be solved twice.
3. Boredom and drudgery are evil.
4. Freedom is good.
5. Attitude is no substitute for competence.
5) If you are tired of reading English, maybe I should move on to technical stuff
6) Create your hacking space, a virtual disk on your machine.
You will need to learn a bit of Linux. If you are a Windows user, I recommend creating a VMWare partition with Ubuntu
If you like Mac, I recommend the more aesthetic Linux Mint.
How to create your virtual disk-

9) Get a  Bit Torrent Client at http://www.utorrent.com/
This will help you download stuff
10) Hacker Culture Alert-
This instruction is purely for sharing the culture but not the techie work of being a hacker
The website Pirate bay acts like a search engine for Bit torrents 
http://thepiratebay.se/
Visiting it is considered bad since you can get lots of music, videos, movies etc for free, without paying copyright fees.
The website 4chan is considered a meeting place to meet other hackers. The site can be visually shocking
http://boards.4chan.org/b/
You need to do atleast set up these systems, read the websites and come back in N month time for second part in this series on how to learn to be a hacker. That will be the coding part.

Secure Browsing from Mobile and PC ( Tor ,PeerNet, WasteAgain)

While Tor remains the tool of choice with pseudo-techie hacker wannabes , there is enough juice and smoke and mirrors on the market to confuse your average Joe.

For a secure browsing experience on Mobile – do NOT use either Apple or Windows OS

Use Android  and this app called Orbot in particular

Installing Tor with a QR code

Orbot is easy to install by simply scanning the following QR code with your Android Barcode scanner.

Android QR code

Installing Tor from the Android Market

Orbot is available in the Android Market.

ENTER PEERNET

If you have a Dell PC, well just use PeerNet to configure and set up your own network around the neighbourhood. This is particularly applicable if you are in country that is both repressive and not so technologically advanced. Wont work in China or USA.

http://support.dell.com/support/edocs/network/p70008/EN/vista_7/peernet.htm

What is a peer network?

A peer network is a network in which one computer can connect directly to another computer. This capability is accomplished by enabling access point (AP) functionality on one of the computers. Other computers can then connect to this computer in the same way that they would connect to a physical AP. If Internet Connection Sharing is enabled on the computer that has the AP functionality, computers that connect to that computer have Internet connectivity as well.

A basic peer network, which requires no networking knowledge or experience to set up, should meet the needs of most home users and small businesses. By default, a basic peer network is configured with the strongest available security (see How do I set up a basic peer network?).

For users who are familiar with wireless networking technology, advanced configuration features are available to do the following:

• Change security settings (see How do I configure my peer network?)
• Choose which method (push button or PIN) computers with Wi-Fi Protected Setup™ capability can join your peer network (see How do I allow peer devices to join my peer network using Wi-Fi Protected Setup technology?)
• Change the DHCP Server IP address (see How do I configure my peer network?).
• Change the channel on which to operate your peer network (see How do I configure my peer network?)

 If you are really really in a need for secure browsing (like you are maybe a big hot shot in the tech world), I suggest go over to VMWare

http://www.vmware.com/products/player/

create a seperate Linux (Ubuntu for ease) virtual disc, then download the Tor Browser Bundle from

https://www.torproject.org/projects/torbrowser.html.en for surfing and a Peernet (above) or  a prepaid one time use disposable mobile pre-paid wireless card. It is also quite easy to delete your virtual disc in times of emergencies (but it is best to use encryption even when in Ubuntu https://help.ubuntu.com/community/EncryptedHome)

IRC chat is less secure than you think it is thanks to BOT  Trawlers- so I am hoping someone in the open source community updates Waste Again for encrypted chats http://wasteagain.sourceforge.net/

What is “WASTE again”?

“WASTE again” enables you to create a decentralized and secure private mesh network using an unsecure network, such as the internet. Once the public encryption keys are exchanged, sending messages, creating groupchats and transferring files is easy and secure.

Creating a mesh

To create a mesh you need at least two computers with “WASTE again” installed. During installation, a unique pair of public and private keys for each computer is being generated. Before the first connection can be established, you need to exchange these public keys. These keys enable “WASTE again” to authenticate every connection to other “WASTE again” clients.

After exchanging the keys, you simply type in the computers IP address to connect to. If that computer is located behind a firewall or a NAT-router, you have to create a portmap first to enable incoming connections.

At least one computer in your mesh has to be able to accept incoming connections, making it a “public node”. If no direct connection between two firewalled computers can be made, “WASTE again” automatically routes your traffic through one or more of the available public nodes.

Every new node simply has to exchange keys with one of the connected nodes and then connect to it. All the other nodes will exchange their keys automatically over the mesh.
