thanks to someone for this tut.
Configuring your Bulletproof FTP Server Tutorial
I am not sure where I found this tutorial, It?s been a while?It might even have been here... ..So if it is one of yours, my hat goes off to you once again....
After reading the excellent tutorial on "Creating an FTP" that Norway posted?
(I would suggest reading and following his tutorial first, then following up with this one)
I thought that perhaps this tutorial might be pretty helpful for those interested in knowing how to configure their Bulletproof FTP Server that don't already know how... Here's how to get started?
This is for the BulletProof FTP Server 2.10. However, It should work fine on most following versions as well.
I'm assuming you have it installed and cracked.
Basics 1. Start the program. 2. Click on Setup > Main > General from the pull-down menu. 3. Enter your server name into the 'Server Name' box. Under Connection set the ?Max number of users" to any number. This is the limit as to how many users can be on your sever at any time. 4. Click on the 'options' tab of that same panel (on the side) 5. Look at the bottom, under IP Options. Put a check in the box ?Refuse Multiple Connections from the same IP?. This will prevent one person from blocking your FTP to others. 6. Also put a check in the 'Blocked Banned IP (instead of notifying client). VERY IMPORTANT! If somebody decides to 'Hammer' (attempt to login numerous times VERY quickly) your server/computer may CRASH if you don't enable this. 7. Click on the 'advanced' tab 8. At the bottom again look at the 'hammering area' 9. Enable 'anti-hammer' and 'do not reply to people hammering' Set it for the following: Block IP 120 min if 5 connections in 60 sec. You can set this at whatever you want to but that is pretty much a standard Click 'OK'
Adding Users 11. Setup > User accounts form pull-down. 12. Right click in the empty 'User Accounts' area on the right: choose 'Add' 13. Enter account name. (ie: logon name) 14. In the 'Access rights' box right click: choose ?Add?. 15. Browse until you find the directory (folder) you want to share. In the right column you will see a bunch of checkboxes. Put a check in the following ones: Read, Write, Append, Make, List, and +Subdirs. Press 'select'. 16. Enter a password for your new FTP account. 17. Click on 'Miscellaneous' in the left column. Make sure 'Enable Account' is selected. Enable 'Max Number of Users' set it at a number other than zero. 1 for a personal account and more that one for a group account. Enable 'Max. no. of connects per IP' set it at 1
18. Under 'Files' enable 'show relative path' this is a security issue. A FTP client will now not be able to see the ENTIRE path of the FTP. It will only see the path from the main directory. Hide hidden flies as well. Put a tick in both of these.
Advanced: You don't need to do any of this stuff, but It will help tweak your server and help you maintain order on it. All of the following will be broken down into small little areas that will tell you how to do one thing at a time.
Changing the Port The default port is always 21, but you can change this. Many ISPs will routinely do a scan of its own users to find a ftp server, also when people scan for pubs they may scan your IP, thus finding your ftp server. If you do decide to change it many suggest that you make the port over 10,000. 1. Setup > Main > General 2. In the 'Connection' Area is a setting labeled 'Listen on Port Number:' 3. Make it any number you want. That will be your port number. 4. Click 'OK'
Making an 'Upload Only' or 'Download Only' ftp server. This is for the entire SERVER, not just a user. 1. Setup > Main > Advanced 2. In the advanced window you will have the following options: uploads and downloads, downloads only, and uploads only. By default upload and download will be checked. Change it to whatever you want. 3. Click 'OK?
While you are running your server, usually you will end up spending more time at your computer than you normally do. Don't be afraid to ban IP's. Remember, on your FTP you do as you want.
When you are online you must also select the open server button next to the on-line button which is the on-line Button
You also have to use the actual Numbered ip Address ie: 66.250.216.67
Or even Better yet, get a no-ip.com address

THE TECHNO CLUB [ TECHNOWORLDINC.COM ] / Windows / Broken Ie, How to fix it
|
on: February 24, 2007, 12:09:06 PM
|
So one of your friends, ?not you of course?, has managed to nuke Internet Explorer and they are unsure how they did it. You?ve eliminated the possibility of viruses and adware, so this just leaves you and a broken IE. Before you begin to even consider running a repair install of the OS, let?s try to do a repair on IE instead.
THE REPAIR PROCESS
Start the Registry Editor by typing regedit from the Run box. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {89820200-ECBD-11cf-8B85-00AA005B4383} and then right-click the ?IsInstalled value.? Click Modify. From there, you will change the value from 1 to 0. All right, go ahead and close the editor and reinstall IE from this location. /http://www.microsoft.com/windows/ie/default.mspx
IF SOMETHING GOES WRONG
If messing with the registry and something goes horribly wrong, you can use ?Last Known Good Configuration (F8 Safe Mode)? or a Restore Point to get back to where you were before, with your settings. Then you can try again, this time taking care to watch the portion of the registry you are changing. Most people who have troubles with this end up changing the wrong registry key.
Hope this tut helps some members.

THE TECHNO CLUB [ TECHNOWORLDINC.COM ] / Web Design / Graphics Design/ Animation / Border And Text Effects In Psp8, For use with PSP8
|
on: February 24, 2007, 12:08:06 PM
|
Do you want to jazz up your graphics? Want to add a bit of pazazz to your art? Well, this guide features some knowledge, border effects, and even directions to make your own swirlie brushes! Now, open PSP and get ready to learn! Let's start off with the basics. ------------------------------------------------- -Border Effects There are two main types of borders, solid borders, and decorative borders. A solid border is like a colored line that raps around the outside of your image and separates graphics from the rest of the page. You can have borders inside the outside borders to make awesome layer effects. Decorative borders are almost the same, except they are not completely connected. (Example - Dashed Borders) ------------------------------------------------- Dashed Borders Open PSP and create an image about 380 x 100 pixels with a white background. Draw a bit with your paintbrush, just add some color. Now maximize your image. It should take up the whole page. Now go up to the toolbar on the very top and click "Selections" and go down right below that and click "Select All" There should be a dotted line going around the outside of your image. We're almost done! YAY! Ok, now look on your keyboard. Go to the very top row next to the F1, F2, F3, F4, and look to the right of the F12 button. It should say "Print Screen". Press it, and it will take a picture of everything currently open on your computer that you can see. Now go to the top toolbar once one. Go under "Edit", move down to "Paste", then move your mouse to the right and select "Paste as New Image" Now, your image has a dashed border, but you can see all the unwanted parts of your workspace. So go to the left toolbar and click the crop tool. It is the small square with a line through it. Now drag the segment the crop tool makes just around the image. You might want to zoom in some (Click the magnifying glass on the left toolbar on the spot you want to zoom in). Once you have it fully outlined with the crop segment, double-click to crop it. Wallah! Your image now has a dashed border. So just go to the top toolbar once again, go under "File" and click "Save As". Then, select the spot and name to save it. ------------------------------------------------- -Font Suggestions and Styles So you know how to make a cool border for your images. Now what about fonts? Well usually, for siggies, you would put a bigger font saying their name, and a smaller font with sub-text. Look at my signature: See how it says "Anonymous" in a large font that matches the background; then under it, it says "SOD's coolest member" (my sub-text) in a smaller font? That's the usual format for text on signatures. Of couse, this isn't the only way. Now, for some font suggestions: Larger Fonts Laurenscript Baby Kruffy (This one is awesome!) Casual Chick Cheri Walt Disney Mullet Dolphins (yippee!) Jelly Belly Flubber Porky's Gilligan's Island Cheeseburger Smaller Fonts Redensek Mullet Georgia Acknowledge Tahoma ------------------------------------------------- Helpful Links http://peachie.nu(a few popups though) Font Places http://www.dafont.com/en/http://www.1001freefonts.com/http://www.fontfreak.com/http://www.acidfonts.com/

Boot Block Recovery For Free
You don't need to pay a measly sum of dollars just to recover from a boot block mode. Here it is folks:
AWARD Bootblock recovery:
That shorting trick should work if the boot block code is not corrupted, and it should not be if /sb switch is used when flashing the bios (instead of /wb switch).
The 2 pins to short to force a checksum error varies from chip to chip. But these are usually the highest-numbered address pins (A10 and above).
These are the pins used by the system to read the System BIOS (original.bin for award v6), calculate the ROM checksum and see if it's valid before decompressing it into memory, and subsequently allow Bootblock POST to pass control over to the System BIOS.
You just have to fool the system into believing that the System BIOS is corrupt. This you do by giving your system a hard time reading the System BIOS by shorting the 2 high address pins. And when it could not read the System BIOS properly, ROM Checksum Error is detected "so to speak" and Bootblock recovery is activated.
Sometimes, any combination of the high address pins won't work to force a checksum error in some chips, like my Winbond W49F002U. But shorting the #WE pin with the highest-numbered address pin (A17) worked for this chip. You just have to be experimentative if you're not comfortable with "hot flashing" or "replacement BIOS".
But to avoid further damage to your chip if you're not sure which are the correct pins to short, measure the potential between the 2 pins by a voltmeter while the system is on. If the voltage reading is zero (or no potential at all), it is safe to short these pins.
But do not short the pins while the system is on. Instead, power down then do the short, then power up while still shorting. And as soon as you hear 3 beeps (1 long, 2 short), remove the short at once so that automatic reflashing from Drive A can proceed without errors (assuming you had autoexec.bat in it).
About how to do the shorting, the tip of a screwdriver would do. But with such minute pins on the PLCC chip, I'm pretty comfortable doing it with the tip of my multi-tester or voltmeter probe. Short the pins at the point where they come out of the chip.
AMIBIOS Recovery bootblock: 1. Copy a known working BIOS image for your board to a floppy and rename it to AMIBOOT.ROM. 2. Insert the floppy in your system's floppydrive. 3. Power on the system while holding CTRL+Home keys. Release the keys when you hear a beep and/or see the floppy light coming on. 4 . Just wait until you hear 4 beeps. When 4 beeps are heard the reprogramming of the System Block BIOS went succesfull, so then you may restart your system.
Some alternative keys that can be used to force BIOS update (only the System Block will be updated so it's quite safe): CTRL+Home= restore missing code into system block and clear CMOS when programming went ok. CTRL+Page Up= restore missing code into system block and clear CMOS or DMI when programming went ok. CTRL+Page Down= restore missing code into system block and do not clear CMOS and DMI area when programming went ok Btw: the alternative keys work only with AMIBIOS 7 or higher (so for example an AMI 6.26 BIOS can be only recovered by using CTRL+Home keys).

************************************************ BLACKOUT Flashing *************************************************
Recovering a Corrupt AMI BIOS chip With motherboards that use BOOT BLOCK BIOS it is possible to recover a corrupted BIOS because the BOOT BLOCK section of the BIOS, which is responsible for booting the computer remains unmodified. When an AMI BIOS becomes corrupt the system will appear to start, but nothing will appear on the screen, the floppy drive light will come on and the system will access the floppy drive repeatedly. If your motherboard has an ISA slot and you have an old ISA video card lying around, put the ISA video card in your system and connect the monitor. The BOOT BLOCK section of the BIOS only supports ISA video cards, so if you do not have an ISA video card or your motherboard does not have ISA slots, you will have to restore your BIOS blind, with no monitor to show you what?s going on.
AMI has integrated a recovery routine into the BOOT BLOCK of the BIOS, which in the event the BIOS becomes corrupt can be used to restore the BIOS to a working state. The routine is called when the SYSTEM BLOCK of the BIOS is empty. The restore routine will access the floppy drive looking for a BIOS file names AMIBOOT.ROM, this is why the floppy drive light comes on and the drive spins. If the file is found it is loaded into the SYSTEM BLOCK of the BIOS to replace the missing information. To restore your BIOS simply copy a working BIOS file to a floppy diskette and rename it AMIBOOT.ROM, then insert it into the computer while the power is on. The diskette does not need to be bootable or contain a flash utility. After about four minutes the system will beep four times. Remove the floppy diskette from the drive and reboot the computer. The BIOS should now be restored.
Recovering a Corrupt AWARD BIOS With AWARD BIOS the process is similar but still a bit different. To recover an AWARD BIOS you will need to create a floppy diskette with a working BIOS file in .BIN format, an AWARD flash utility and an AUTOEXEC.BAT file. AWARD BIOS will not automatically restore the BIOS information to the SYSTEM BLOCK for this reason you will need to add the commands necessary to flash the BIOS in the AUTOEXEC.BAT file. The system will run the AUTOEXE.BAT file, which will in turn flash the BIOS. This is fairly easy. Here are the steps you need to take.
? Create a bootable floppy diskette ? Copy the BIOS file and flash utility to the diskette ? Create an text file with any standard text editor and add the following lines
@ECHO OFF FLASH763 BIOSFILE.BIN /py
In the above example I am assuming that you are using the FLASH763.EXE flash utility. You will need to replace the FLASH763 with the name of whatever flash utility you are using, and replace the BIOSFILE.BIN with the name of the BIOS file you are using. You will also need to change the ?/py? to whatever the command is for your flash utility to automatically program the BIOS without user intervention. If you do not know the command to automatically flash your BIOS type the name of the flash utility with a space and then /? to display the utility?s help screen. The help screen should pecify the command switch to automatically flash your BIOS. If you are using the FLASH763.EXE utility then the switch to automatically flash your BIOS is ?/py?.

Bit Torrent Tutorials
The first things you need to know about using Bit Torrent: -- Bit Torrent is aimed at broadband users (or any connection better than dialup). -- Sharing is highly appreciated, and sharing is what keeps bit torrent alive. -- A bit torrent file (*.torrent) contains information about the piece structure of the download (more on this later) -- The method of downloading is not your conventional type of download. Since downloads do not come in as one big chunk, you are able to download from many people at once, increasing your download speeds. There may be 100 "pieces" to a file, or 20,000+ pieces, all depending on what you're downloading. Pieces are usually small (under 200kb) -- The speeds are based upon people sharing as they download, and seeders. Seeders are people who constantly share in order to keep torrents alive. Usually seeders are on fast connections (10mb or higher).
In this tutorial, I will be describing it all using a bit torrent client called Azureus. This client is used to decode the .torrent files into a useable format to download from other peers. From here on out, I will refer to Bit Torrent as BT.
Which BT client you use, is purely up to you. I have tried them all, and my personal favorite is Azureus for many reasons. A big problem with most BT clients out there, is that they are extremely CPU intensive, usually using 100% of your cpu power during the whole process. This is the number one reason I use Azureus. Another, is a recently released plug-in that enables you to browse all current files listed on suprnova.org (the #1 source for torrent downloads).
Before you use the plug-in, take a look at /http://www.suprnova.org, and browse the files. Hold your mouse over the links, and you'll notice every file ends in .torrent. This is the BT file extension. Usually, .torrent files are very small, under 200kb. They contain a wealth of information about the file you want to download. A .torrent file can contain just 1 single file, or a a directory full of files and more directories. But regardless, every download is split up into hundreds or thousands of pieces. The pieces make it much easier to download at higher speeds. Back to suprnova.org. Look at the columns:
Added | Name | Filesize | Seeds | DLs (and a few more which aren't very useful.)
I'll break this down. Added: Self explanitory, its the date the torrent was added. Name: Also self explanitory. Filesize: Duh Seeds: This is how many people are strictly UPLOADING, or sharing. These people are the ones that keep .torrent files alive. By "alive", I mean, if there's no one sharing the .torrent file, no one can download. DLs: This is how many people currently downloading that particular torrent. They also help keep the torrent alive as they share while they download.
It's always best to download using a torrent that has a decent amount of seeders and downloaders, this way you can be assured there's a good chance your download will finish. The more the better.
Now that you should understand how torrent files work, and how to use them, on to Azureus! First, get JAVA! You need this to run Azureus, as java is what powers it. Get Java here: /http://java.sun.com/j2se/1.4.2/download.html Next, get Azureus at: /http://azureus.sourceforge.net Next, get the Suprnovalister plugin from /http://s93732957.onlinehome.us/storage/suprnovalister.jar
Install Java JRE before you do ANYTHING.
Install Azureus, and then in the installation folder, create 2 more folders. ./Plugins/suprnovalister (For example, if you installed Azureus to C:\PROGRAM FILES\AZUREUS, create C:\PROGRAM FILES\AZUREUS\PLUGINS\SUPRNOVALISTER). Next, put the suprnovalister.jar file that you downloaded, in that folder.
Load up Azureus, and if you want, go through the settings and personalize it.
The tab labeled "My Torrents" is the section of Azureus you need the most often. That lists all your transfers, uploads and downloads. It shows every bit of information you could possibly want to know about torrents you download.
In the menu bar, go to View > Plugins > Suprnova Lister. This will open up a new tab in Azureus. Click on "Update Mirror". This will get a mirror site of suprnova.org containing all current torrent files available. Once a mirror is grabbed, choose a category from the drop-down box to the left and click "Update". Wah-lah, all the available downloads appear in the main chart above. Just double click a download you want, and bang its starting to download. Open the "My Torrents" tab again to view and make sure your download started.
After your download has finished, be nice, and leave the torrent transferring. So people can get pieces of the file from you, just as you got pieces from other people.
Alternatively, if you don't want to use the plugin... you can just head to suprnova.org and download files to any folder. Then go to File > Open > .torrent File in Azureus.
This should about wrap it up for the Bit Torrent Tutorial. If you guys think of anything I should add, or whatnot, just let me know and I'll check into it.

THE TECHNO CLUB [ TECHNOWORLDINC.COM ] / Hardware / BIOS Update Procedure
|
on: February 24, 2007, 12:00:21 PM
|
BIOS Update Procedure
All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this.
Please read the following instructions in full before starting a Flash BIOS upgrade: A. Create a Bootable Floppy (in DOS)
?With a non-formatted disk, type the following:
format a:/s
?If using a formatted disk, type:
sys a:
This procedure will ensure a clean boot when you are flashing the new BIOS.
B. Download the BIOS file
?Download the correct BIOS file by clicking on the file name of the BIOS file you wish to download.
?Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip for Windows 95 shareware/ evaluation copy for that one time use from _www.winzip.com or _www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.
?You should have extracted two files:
Flash BIOS utility eg: flash7265.exe (for example)
BIOS eg: 6152J900.bin (example)
Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.
C. Upgrade the System BIOS
During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.
Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22
?At the A:> prompt, type the corresponding Flash BIOS utility and the BIOS file with its extension.
For example:
flash625 615j900.bin
?From the Flash Memory Writer menu, select "Y" to "Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE: eg: a:\613J900.bin
Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.
?Select "Y" to "Are you sure to program?"
?Wait until it displays "Message: Power Off or Reset the system"
Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete the procedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)
Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.
For AMI BIOS Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.
BIOS Update Tips note: 1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to. (This option is not available when flashing an AMI BIOS).
2. If you have problems installing your new BIOS please check the following:
Have you done a clean boot? In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS.
If you have not used a bootable floppy, insure a clean boot either by
a) pressing F5 during bootup
b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by using the EDIT command.
Have you booted up under DOS? Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers. Important: Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above procedure (format a: /s and rebooting from a:\).
Have you entered the full file name of the flash utility and the BIOS plus its extension? Do not forget that often you will need to add a drive letter (a:\) before flashing the BIOS. Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c:\ your will need to type a:\615j900.bin, rather than 615j900.bin only.

THE TECHNO CLUB [ TECHNOWORLDINC.COM ] / Windows / Bin & Cue Simple Tut
|
on: February 24, 2007, 11:58:47 AM
|
BIN & .CUE simple tutorial.
There always seems to be the question "what do I do with a .bin and .cue file" in these forums so I figured I would write a quick and simple tutorial. Please feel free to add more.
So you have downloaded two files, one with a .bin extension and one with a .cue extension. "What do I do with these?" you ask. There are a number of options.
BURN TO CD
You will need either NERO, CDRWIN or FIREBURNER to burn the file.
To burn with NERO: Start NERO, choose FILE, choose BURN IMAGE, locate the .cue file you have and double click it. A dialog box will come up, for anything other than music make sure you choose DISC-AT-ONCE (DAO). You can also turn off the simulation burn if you so choose. Then burn away.
To burn with CDRWin: Start CDRWin, choose the button on the top left, choose LOAD CUESHEET, press START RECORDING.
To burn with Fireburner: Start Fireburner, click on the button on the bottom left corner "VISUAL CUE BURNER/BINCHUNKER", press the right mouse button and choose LOAD TRACKS FROM .CUE and choose the correct .CUE file, press the right mouse button again and chooseselect "Burn/Test Burn", choose DISK AT ONCE (DAO), disable TEST BURN and MULTISESSION, press OK.
.CUE ERRORS The most common error you will get with a .cue file is when it points to an incorrect path. This is easily fixed. Find the .bin file, copy the exact title including the .bin extension. Now find the .cue file, open the .cue file using notepad. It should look similar to this:
FILE "name of file.bin" BINARY TRACK 01 MODE2/2352 INDEX 01 00:00:00 TRACK 02 MODE2/2352 INDEX 00 00:04:00 INDEX 01 00:06:00
Delete everything in the quotes, in this case we would delete name of file.bin. Now place the title you copied in between the quotes. Save the changes and close out. Thats it, your .cue file should work now.
OTHER WAYS TO USE .BIN & .CUE FILES
VCDGear: This program will allow you to extract MPEG streams from CD images, convert VCD files to MPEG, correct MPEG errors, and more.
Daemon Tools: This program creates a virtual drive on your PC which will allow you to "mount" the .cue file and use whatever is in the .bin file without having to burn it to a cd.
ISOBuster: This program will allow you to "bust" open the .bin file and extract the files within the .bin. _________________

Big Brother and Ndisuio.sys A new Internet phenomenon?
Ndisuio.sys, a very mysterious system file is present in Windows XP and is a driver for wireless things such as wi-fi and bluetooth. However, there have been many issues with this file downloading immense amounts of data and perhaps causing activity that is "big brother"ish.
The fact that hardly any information on this file downloading data is available by Microsoft makes things quite suspicious about it. It has even been noted that it looked as if it was transferring data to major companies like Comcast, Road Runner, Time Warner, BTC and Verizon.
The good news is, it turns out this file duplicates data that is sent/received, so wherever you go, it will also transfer the data to that file but it does not leave the computer/network so it's not spyware. So it's not as much of a big brother situation then it looks like. It simply performs internal communication tasks and stands for NDIS user I/O, hence, NDISUIO. NDISUIO is also used as a driver by many developers as it makes certain wireless network tasks easier such as implementing it for 802.11x connections. Some firewalls also use it as it can get the data in order to filter it.
But duplicating this data can hog resources for no reason, so disabling it is the best thing to do. The data rate of this file's received data is huge, so that indicates that the data transfer is not over the Internet, but locally. So it's just a duplicate of network activity but because it's local everything transfers faster but uses more resources then casual internet usage as there's more data involved at a given time span of 1 second, for example.
To disable this file, go to the control panel, administration tools, services, Wireless Zero Configuration, double click and disable it. This file is probably required to run if you use any linksys wireless devices.

Beep Code Manual, Better Than Gold Techies, American Megatrends Int. & Phoenix
(I'm IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected. Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.
AMI Beep Codes
Beep Code Meaning 1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard. 2 beeps Memory parity error. The parity circuit is not working properly. 3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory. 4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard. 5 beeps Processor failure. The system CPU has failed. 6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode. 7 beeps Virtual mode exception error. 8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card. 9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty. 10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS. 11 beeps Bad cache memory. An error in the level 2 cache memory. 1 long beep, 2 short Failure in the video system. 1 long beep, 3 short A failure has been detected in memory above 64K. 1 long beep, 8 short Display test failure. Continuous beeping A problem with the memory or video. BIOS Beep Codes
Phoenix Beep Codes
Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes. Click here for AMI BIOS beep codes.
4-Beep Codes
Beep Code Meaning 1-1-1-3 Faulty CPU/motherboard. Verify real mode. 1-1-2-1 Faulty CPU/motherboard. 1-1-2-3 Faulty motherboard or one of its components. 1-1-3-1 Faulty motherboard or one of its components.

THE TECHNO CLUB [ TECHNOWORLDINC.COM ] / Internet / Bandwidth Explained!
|
on: February 24, 2007, 11:46:58 AM

This is well written explanation about bandwidth, very useful info.
BandWidth Explained
Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.
Network Connectivity
The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.
If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).
Traffic
A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.
Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).
If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).
Hosting Bandwidth
In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).
A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.
How Much Bandwidth Is Enough?
It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor
If you intend to allow people to download files from your site, your bandwidth calculation should be:
[(Average Daily Visitors x Average Page Views x Average Page Size) + (Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor
Let us examine each item in the formula:
Average Daily Visitors - The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.
Average Page Views - On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.
Average Page Size - The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.
Average Daily File Downloads - The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.
Average File Size - Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.
Fudge Factor - A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.
Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.
Summary
Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.
