free gprs in sri lanka , why pay for mobile broad band when you can have it for free!!!

By Gayan Ranasinghe

This trick works with mobitel network in sri lanka.And i must say that this is not 100% perfect broadband.This procedure is a little annoying and not totally comfortable BUT its FREE gprs after all!

This trick may be useful for you mainly when using gprs on your phone.you can use this TRICK to download small files less than 800kb or so.(generally,mobitel charges 1cent per kb,so technically you get 8 rupees of gprs for FREE! per session)

Its really simple.Do you have a mobitel connection in your mobile?

theres one condition for our little trick to work

***you must have less than 1.50rs & more than 1.00rs credit to be able to perform this TRICK & basic knowledge of gprs usage***

now open your opera mini browser (if you don't have opera mini installed in your mobile,you can download for free @ www.operamini.com)and browse pages as usual.you will only be able to browse for about 30seconds and you will be able to download upto 800-900kb of data in that time(if you have 3g in your phone,depends on your device).then you have to disconnect your current connection using connection manager(in Nokia phones) or the relevant utility depending on the phone.then you can restart browsing.

How can I open an EXE file on a Mac?

I use a Macintosh. It says

The document "NAV80TRY.EXE" could not be opened, because the application program that created it could not be found.

You can convert exe file to mac .app file through some tools like macpack or also use bootcamp software on Mac for running exe file, it is better and faster than using Virtual PC. Right now it is on R & D stage.link for macpack

How to Change Mac IP Address

Check the IP Address

1. Step 1

   Launch the Apple Menu. Select "System Preferences." Then click "Network Control

   Things You'll Need:

   • Apple Mac computer
   • Internet connection

   Panels" and click "TCP/IP."

2. Step 2

   Check the IP address in the list of connections. Your Mac has an IP address, and some of your electronic devices may also have their own IP addresses.

3. Step 3

   Visit a website such as What Is My IP for a utility that reads your Mac IP address (see Resources below). It will automatically detect your IP address and provide it for you.

Change an IP Address Automatically

4. Step 1

   Obtain a new IP address from your Internet Service Provider or Network Administrator. This step might not be necessary, as most broadband connections use dynamic IP addresses. This means that every time your Mac connects to the Internet, it will be assigned a new IP address. You might not need to do anything in order to change the address.

5. Step 2

   Get the new IP address from your ISP, because if two computers have the same address, neither one of them will be able to connect to the Internet.

6. Step 3

   Realize each computer connecting to the Internet must have its own unique IP address. Have your ISP assign one that nobody else is using or you will waste time trying to guess the right number.

Change Your Mac IP Address Manually

7. Step 1

   Select the network configuration that has the green dot next to it, from the "TCP/IP" screen you opened before. This is your active connection and will probably be the "Built-In-Ethernet" option in the drop-down box. Then click the "Configure" button at the bottom of the dialog box.

8. Step 2

   Click the "Configure IPV4" drop down menu next and choose "Manually."

9. Step 3

   Type in your new IP address in the box under the TCP/IP menu. Simply delete the number that is in there and enter your new one.

10. Step 4

    Click "Save." Your address has now been changed.

Apple’s easy to hack after all?

Apple apparently left off tools that are available in the GNU compiler collection to protect against exactly this sort of attack. Dai Zovi even says that the current version of OS X is easier to hack than XP. Ouch.

Does this mean that Mac’s are less secure than PC’s? Not really, since they’re still such a small percentage of the market that they’re not under heavy attack by malware. Even though the capability exists to take advantage of this vulnverability, the return on time and effort is still a lot better on the Windows side for malware writers. Of course, someone could always decide that Macs are an underutilized target for malware and create something interesting.

Tracking the source of DOS attack with Cisco IOS

Problem: Enterprise is under Denial Of Service Attack that brings down key elements of the business or the whole network at all.
To track the attacker is the first step in handling the attack and unless the flood is coming from inside (most probably not in a well managed LAN) you will need help of your Service Provider to find out the origin. Unfortunately Service Provider’s (SP) backbone is not well suited for such forensics, as its business role is
to provide uninterrupted connectivity to ALL the clients , not only you, so SP will not enable ACLs/ip accounting/Netflow on their backbone to identify where the attack is coming from . And if source Ip of the attack is spoofed you can’t do much .

For such cases Cisco came with the nice feature called
ip source tracking that will gather flow statistics for specific destination
IPs (of victim) and periodically will export them for viewing, and will do all this without overloading the backbone router it is enabled on (Of course relevant if your SP is using Cisco gear) . Here are details:

– Enable it globally for the victim IP , here IP being attacked is 63.45.33.22

Edge(config)#ip source-track 63.45.33.22

- If you want (and if this is being done by SP they will not) you may create log entries:
Edge1(config)#ip source-track syslog-interval 2
Then you will see in logs (good for reminding to disable this afterwards) :
May 28 10:55:47.105: %DOS_TRACK-5-CFG: IP Source Tracker configured for 1 hosts

- Also you may define how often to export gathered info to be viewed (seems to depend on the platform ) :

Edge(config)#ip source-track export-interval 60

- And finally , you see the data accumulated so far :

Edge#sh ip source-track
Address SrcIF Bytes Pkts Bytes/s Pkts/s
63.45.33.22 Fa0/0 141G 485M 8244 141

Most important here will be the Source interface (in this router there is only 1 ingress interface , in real backbone you will have few feeds) where you see most of the incoming traffic for this destination IP. Then you (SP) would go to the upstream router connected to this local interface, enable the same source tracking and so on. Up to the last point in the backbone where the attacking traffic enters
the backbone of SP out of some upstream SP . Then SP would have option to contact the abuse of this upstream provider for them to investigate the issue further, or at least divert the attack to the black hole at the entry point, so end client would not be affected at all.

Ten tweaks that will improve Nokia N95 battery life by 328%

here is no way getting around the fact battery life on the Nokia N95 is less than great. Almost every N95 review addresses this issue in one way or the other. Opinions seem to range from infuriated "Nokia should provide a more powerful battery for this type of device" to apologetic "a communication and multi media power house is bound to run its battery dry in no time".

Whatever the case may be, there are things that can be done to improve upon the «default» N95 battery life time. Improvements come from tweaking a few, selected settings from their default values.

I have divided this authoritative N95 battery tweaking guide into two parts: first I will show you a few basic battery friendly optimizations and habits that can be employed by everyone. Next, I provide a few advanced tweaks that on the one hand might not fit everybody, on the other hand result in the most significant improvements.

Right, let's get cracking!

Basic Optimizations

• Update phone firmware - new firmware might include improvements to battery management.
• Bluetooth - keep it off unless needed. Put bluetooth management on «active standby» screen for easy access («Tools» | «Settings» | «General» | «Personalisation» | «Standby mode» | «Active standby apps..»).
• Brightness timeout …not more than 10 seconds («Tools» | «Settings» | «General» | «Personalisation» | «Display» | «Light time-out»).
• Screen brightness - turn it down a notch or two («Tools» | «Settings» | «General» | «Personalisation» | «Display» | «Light sensor»).
• Lower the standby timeout - mine's set to 1 minute («Tools» | «Settings» | «General» | «Personalisation» | «Display» | «Power saver time-out»).
• Camera - do not walk around with "live" viewfinder¹.

Rocket Science Tweaks

• WLAN scanning - turn it off…scan manually, or turn scanning on when needed («Tools» | «Settings» | «Connection» | «Wireless LAN» | «Scan for networks»).
• 3G - turn it off - especially in areas with poor coverage, where the N95 otherwise will spend stupefying amounts of power searching for networks («Tools» | «Settings» | «Phone» | «Network» | Set «Network mode» to «GSM»).
• WLAN transmit power (TX power level) - turn it down to, say, 4 mW. («Tools» | «Settings» | «Connection» | «Wireless LAN» | «Options» | «Advanced settings» - say YES to the prompt - scroll down to TX power level choose options/change/ and select 4 mW.).
• 10th tweak - it simply amounts to switching the phone into »offline« mode at night. In the »offline« mode, the cellular network connectivity is off (but WLAN and Bluetooth are still available) and the rationale is that since you do not make calls while you are sleeping, you might as well let the battery get some rest too.

Enjoy … and by the way, I have no idea if employing these tweaks will actually lead to a 328% improvement, but it is a nice figure, don't you think?
