Male Domination of the Internet Is Over, Study Finds.

The days of men dominating the Internet may be over, a new study finds. But, according to the study, the two sexes use the Web for very different things. The study says 68 percent of men and 66 percent of women now go online. Since women make up a larger portion of the population, that means they outnumber men in cyberspace. The research suggests men largely go online to pursue solitary pursuits, while women use the Internet to enrich their existing relationships. Men go online to further their hobbies, for example. They are much more likely to use the Internet to read online, take Web classes and take part in sports-fantasy leagues. More men than women will download software and music or use a Web cam. By contrast, 94 percent of women who go online do so for e-mail. Women see e-mail as a way to nurture friendships. They'll write to family and friends to share news and stories, ask for advice and discuss plans. When men use e-mail, it tends to be for work-related activities or for forwarding jokes or humorous stories. Believe it or not, women are just as likely as men to use the Internet to play games, listen to music, watch videos and share files. And both sexes are equally likely to gamble online. In fact, 4 percent of the population surveyed gambled online. Source: ABC News Tags: Internet, Sexes, Gr33n Data

JNCIS-FWV

Today I've passed the JNCIS-FWV exam. The JNCIS-FWV is designed for networking professionals with advanced knowledge of, and experience with, Juniper Firewall/VPN products and ScreenOS software. The JNCIS-FWV exam tests for a wider and deeper level of knowledge than does the JNCIA-FWV exam.

pysqlite

SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine. While pysqlite is a Python DB-API 2.0 interface for it. So in order to install pysqlite you have to have sqlite installed. But unfortunately when trying to install sqlite using apt-get it seems that some header files were missing that prevented pysqlite from being installed properly. So after installing sqlite from source, I was able to install pysqlite successfully.

Kubuntu = Ubuntu + KDE

Ubuntu is a Linux distro based on Debian and uses Gnome as Desktop Manager (GDM), and there is a branch of Ubuntu that uses KDE (KDM) instead called Kubuntu. So today I tried to install KDesktop on Ubuntu, but unfortunately I was not satisfied with it. I think it is too heavy and crashes all the time. May be I was supposed to install Kubuntu in the first place, and may be it's new KDE versions that suck. Tags: KDE, Gnome, Gr33n Data

Ubuntu Synaptic Without CD

Sometimes when using Ubuntu "Synaptic Package Manager" or the command line "apt-get" to install a certain application, they ask you to insert the Ubunut CD in order to continue. So, in order to let them search online and skip looking in the cdrom you can go to "/etc/apt/sources.list" and comment the following line "deb cdrom: ...etc." to look like this "#deb cdrom: ...etc." Tags: Ubuntu, Debian, Gr33n Data

Linux Run Levels

Like most of the UNIX like operating systems, linux has different Run Levels, one for running as a single user, one for multi-user, may be one for GUI, even one for reboot and another one for halt. In the file "/etc/inittab" you can find the default Run Level, eg:

id:2:initdefault:

You can find there also the different Run Levels on your system and which is which. In Ubuntu for example it will look like this:

# /etc/init.d executes the S and K scripts upon change # of runlevel. # # Runlevel 0 is halt. # Runlevel 1 is single-user. # Runlevels 2-5 are multi-user. # Runlevel 6 is reboot.

Then in the "/etc" you may find different folders "rc1.d", "rc2.d", and so on. Each folder contains the different scripts to be executed whenver the system enters its equivalent Run Level. Tags: Linux, Runlevel, Gr33n Data

Foundry IEEE 802.1x

To configure a foundry switch in order to authenticate people using their IEEE 802.1x clients on their PCs.

You need to enable the RADIUS authentication on the switch first

BigIron(config)# aaa authentication dot1x default radius

Then you net to tell it the RADIUS server's IP and other parameters

radius-server host 209.157.22.99 auth-port 1812 acct-port 1813 default key abc123 dot1x

Now let only one user has access to ethernet port "3/2"

BigIron(config)# int e 3/2
BigIron(config-if-e100-3/2)# port security
BigIron(config-port-security-e100-3/2)# maximum 2
BigIron(config-port-security-e100-3/2)# exit

Then enable the 802.1x on the switch, and enable multi-user policy

BigIron#(config) dot1x enable
BigIron#(config-dot1x)# multi-user-policy enable

And enable flow-based ACL

BigIron#(config) interface e 3/11
BigIron#(config-if-e1000-3/11)# ip access-group flow-mode
BigIron#(config-if-e1000-3/11)#exit

Configure place holder ACL, just a fake ACL with fake IP in it to redirect the first packet of the session to the CPU

BigIron(config)# access-list 131 deny tcp host 1.1.1.1 any
BigIron(config)# access-list 131 deny udp host 1.1.1.1 any
BigIron(config)# access-list 131 deny icmp host 1.1.1.1 any
BigIron(config)# access-list 131 permit ip any any

BigIron(config) interface e 3/11
BigIron#(config-if-e1000-3/11)# ip access-group flow-mode
BigIron#(config-if-e1000-3/11)# ip access-group 131 in
BigIron#(config-if-e1000-3/11)# ip access-group 131 out
BigIron#(config-if-e1000-3/11)# exit

So, if the source MAC address of the flow is already associated with a successfully authenticated 802.1X host that has a dynamically assigned IP ACL applied to it, then that dynamically assigned IP ACL is applied to the flow. When a port is authenticated using 802.1X security, an IP ACL or MAC address filter that exists in the running-config on the Foundry device can be dynamically applied to the port. To do this, you configure the Filter-ID (type 11) attribute on the RADIUS server. The Filter-ID attribute specifies the name or number of the Foundry IP ACL or MAC address filter. For example, " ip..in", applies the specified numbered ACL to the 802.1X authenticated port in the inbound direction.

So to configure a dynamic ACL to permit incoming traffic from 10.0.0.4 then add the following command to the switch: " access-list 2 permit host 10.0.0.4", and then make the RADIUS send the following attribute value " ip.2.in"
You may do the same but with a MAC filter by applying the following command on the switch: " mac filter 2 permit 3333.3333.3333 ffff.ffff.ffff any etype eq 0800" and let the RADIUS send this: " mac.2.in"

Ubuntu - XMMS Freezes

I've noticed that whenever you try to run XMMS on Ubuntu it freezes, but finally I've found the solution for that ... To install it:

apt-get install xmms apt-get install xmms-mp3 apt-get install xmms-mad

Then go to "Options->Preferences->Audio I/O Plugin->Output Plugin" and set it to "eSound Output Plugin..." The last trick helps in Beep-Media-Player too. Tags: Ubuntu, XMMS, Gr33n Data

Python - libgmail Tutorial

This is a short tutorla about libgmail. Which is a Library to provide access to Gmail via Python. Tabs are important in python as they indicate the different code blocks, since they do not have "{" and "}" like those in C and C++. So I'll replace the tabs here with [TAB], since it's hard to write the proper format in HTML.

First of all lets see how can we get the libgmail help, a.k.a man pages:

>>>import libgmail
>>>help(libgmail)

Then lets see how can we retrieve the messages in our the inbox:

>>>import libgmail
>>>ga = libgmail.GmailAccount("username@gmail.com", "password")
>>>ga.login()
>>>folder = ga.getMessagesByFolder("inbox", True)
>>>for thread in folder:
>>>[TAB]print "Thread:", thread.id, "Subject:", thread.subject
>>>[TAB]for msg in thread:
>>>[TAB][TAB]print "Msg:", msg.id, ",Author", msg.author, ",Subject:", msg.subject

Now lets say we want to print all the attached files in all the messages labled by "projectx"

>>>import libgmail
>>>ga = libgmail.GmailAccount("username@gmail.com", "password")
>>>ga.login()
>>>folder = ga.getMessagesByLabel("projectx", True)
>>>for tread in folder:
>>>[TAB]for msg in thread:
>>>[TAB][TAB]for attach in msg.attachments:
>>>[TAB][TAB][TAB]print attach._getContent()

You may also send a message this way:

>>>import libgmail
>>>ga = libgmail.GmailAccount("username@gmail.com", "password")
>>>ga.login()
>>>msg=libgmail.GmailComposedMessage("friend@gmail.com", "SubjectHere", "BodyHere")
>>>ga.sendMessage(msg)

To send attachmented files into the message:

>>>import libgmail
>>>ga = libgmail.GmailAccount("username@gmail.com", "password")
>>>ga.login()
>>>myFiles = ["/file1", "/file2", "/file3"]
>>>msg=libgmail.GmailComposedMessage("friend@gmail.com", "SubjectHere", "BodyHere", filenames=myFiles)
>>>ga.sendMessage(msg)

Finally I've noticed that sometimes the sendMessage() function fails - returns "HTTP Error 404: Not Found", and hope that they are going fix it soon. Actually the function fails on the first time but when you call it again it works, so you may use a "try-except" statement like the one below:

>>>try:
>>>[TAB]ga.sendMessage(msg)
>>>except:
>>>[TAB]ga.sendMessage(msg)

Better Check For Your Sanity

It doesn't hurt to take a hard look at yourself from time to time, and this should help get you started During a visit to the mental asylum, a visitor asked the director what the criterion was which defined whether or not a patient should be institutionalized. "Well," said the director, "We fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub." "Oh, I understand," said the visitor. "A normal person would use the bucket because it's bigger than the spoon or the teacup." "No." said the director, "A normal person would pull the plug." Do you want a room with or without a view?

IEEE OUI & Company ID's

The MAC address is six bytes (48 bits) long, where the first three bytes (OUI) represent the manufacturer of the Network Card. And here is a link from IEEE in order to search for the different OUI's and their equivalent Companies.

One nice trick to know the manufacturer of a certain host is to "ping" it (it has to be in the same subnet with you), and then type "arp -a" to get his MAC address.

She also knows whole dictionaries, and encyclopedias by heart, and offers a variety of fun activities as well.
But it's really fishy that she does all of this for free! I think there is some hidden agenda out there. May be they have some plans to charge people for such services. Or may be they collect some date about people's behavior etc.

Python Mobile Bluetooth Console

So, now you wanna write Python scripts on your phone, but you are sick of the phone keyboard. Then it is time for BTConsole (Bluetooth Console), where you can have a console connection to the Mobile Phone from your PC using the Bluetooth connection as a Serial Port Emulator. This can be done on both Windows or Linux, but I am going to describe the Linux part as I don't like Windows and also I failed to set it up on it. First of all you have to have the Bluetooth Protocol Stack (BlueZ) installed on your machine. You may also use an "ipconfig" or "ifconfig" like command on you Computer to get information about your Computer's Bluetooth Address (It looks like the MAC Address) and so ... this command is called "hciconfig" Also to discover the Bluetooth devices near you, use "hcitool scan" Now create a Virtual Port (/dev/rfcomm0) on your Linux Machine for the Bluetoot connection and start listening on that port ... Type the following two commands on you computer:

"sdptool add-channel=2 SP" (It shall tell you someting like "Serial Port service registered" now) "rfcomm listen /dev/rfcomm0 2" (It shall tell you something like "Waiting for connection on Channel2")

Then on you Mobile Phone, go to Python (You have Python for Series60 installed on your phone, don't you !?). And choose Bluetooth Console from the Options menu. It should connect to the computer now. And the following will be shown on you computer "Connection from AA:BB:CC:DD:EE:FF to /dev/rfcomm0" then "Press CTRL-C for hangup", where AA:BB:CC:DD:EE:FF is your Mobile's Bluetoot Address The Linux equivalent to HyperTerminal is called minicom, so it's time to use it to open a console connection to the mobile phone. To run minicom type "minicom -s -m" then choose "Serial Port Setup" and set the Serial Device to "/dev/rfcomm0" and leave the rest as it is. Now press escape and exit the Serial Port Setup Menu. Here we go, you are now connected to the Python Shell on your Mobile Phone. If you'd like you may use this to send an SMS from your PC:

>>> import messaging
>>> messaging.sms_send("+20101234567",u"Hello World")

Where +20101234567 is the phone number you want to send your SMS to. Resources:

• Nokia Discussion Forum

Python for Nokia Series60

It is really interesting to write you own Softwares for your Mobile Phone. When I decided to write code using C++ (C and C++ are my favorites), I was shocked to find that Nokia has released a Windows SDK only, and it is limited to some creepy and non-free IDE's like MS Visual Studio and so. On the other hand I hate Java, and can never be used to it. So I was finally happy to find that there is a Python interpreter for Nokia Series 60 Phones. I've installed the Python for Nokia interpreter (PyreplForSeries60.SIS) a couple of days ago, and here I am starting to learn Python, which seems to be a very nice scripting language so far.
