DOS Tips in XP
Windows XP cmd tip (DOS isn’t dead... it just smells funny) Some command-line folder creation examples:

To create multiple folders at once, add them directly to the "md" command:
C:\> md this is a test

To create a folder several folders deep, use:
C:\> md this\is\a\test

Creating a folder with a long name requires the double-quote at the beginning:
C:\> md "this is a test

Bonus tip: Windows XP supports the forward slash "/" as a folder divider. Unix/Linux users: don't let the DOS environment get you down. Use a Unix-style CD command to change your present working directory:
C:\> cd Windows/system32/drivers/etc

New to grex? Type help at the login prompt

(ttyp2) grex login: newuser
newuser program (Version: February 29, 1996)


Welcome to Grex, a service of Cyberspace Communications,
located in
Ann Arbor, Michigan, USA.

Note: Grex does not allow bots of ANY kind--they will not work
here. IRC only works for paying members. Bringing over
your own copies WILL NOT WORK. Do not FTP IRC/bots to Grex.
EGGDROP WILL NOT WORK HERE. BOUNCERS WILL NOT WORK HERE.


Grex is a Sun-4/670 MP, running SunOS 4.1.4. It has 256M of RAM and
8GB of hard disk space. We have 11 public dial-in phone lines
and a dedicated 128K ISDN connection to the Internet. Grex is run
by an all-volunteer staff. There is no software upload/download area.


You may be wondering what kind of system Grex is. To help explain
that, here is the Grex Declaration of Principles:


Press ?

Declaration of Principles



This system is intended to foster community education and the
spiritual and intellectual enrichment of its users through
the peaceable interchange of ideas.
The members of this system hope to attract a large, diverse, and
mature group of thinking individuals and thereby to contribute
to a better-informed citizenry.
Governance of the system is based on cooperative principles,
including open membership, democratic control, and non-
profit economics.
This is an open-access system; the public is welcome. However,
regular users are encouraged to become members and help
support the system financially. Voting on system policy
matters is restricted to members.

It should go without saying that the system is specifically NOT

intended for any illegal purpose.

Users are asked to be considerate of others, and are especially

asked to make a point of setting a good example for those

few who may from time to time fail to return the favor.

Limitations of Grex

(or, The Tragedy of the Electronic Commons)



Because of the popularity of Grex, we're *swamped* with all the

traffic going over our Internet link. This link is only 128K--over

which people telnet in, mail flows, FTP, Lynx, and all the other

Internet applications share (or rather, fight over). We're sorry

to have to talk about restrictions, but we need your help!



Grex is primarily a computer conferencing system. Note that

WE ARE NOT AN INTERNET PROVIDER. This means that we aren't a good

place to store files, do FTPs from, etc. Please do try out the

conferences; we have many topics ranging from the silly to the

serious.



You will not be able to use most Internet services (telnet, FTP,

etc.) once you've made an account here. You must first become a

member in order to have access to these programs. Bringing over your

own copy of telnet/ftp/whatever, will not work.



We need your help to keep Grex's Internet connection working at

anything close to a reasonable speed. There are three main areas

of concern--we'd really appreciate it if:

Press ?



- You do not subscribe to large mailing lists and then forget about them!

If you decide to leave Grex, *please* unsubscribe yourself from the lists

you are on. Mail is the single most resource intensive application on Grex.

Your help in curbing "mail bloat" is sincerely appreciated! If you create

a ".forward" file here, do remember that all the mail you get on Grex will

*twice* slow Grex down for everybody who uses Grex (once coming in and once

going back out of Grex).



- Do not create mailing lists.



- Do not send or receive more than 100 K of mail in a day. Less is better!



- You do not store, mail or FTP GIF, JPG or other data files here. Because

of our slow Internet link, each transfer slows everything else down just

a little more. Graphics can't be on your web pages here anyway.



- For programmers: Please don't bring over large software packages without

talking to staff first. Anything net related won't run once you've compiled

it anyway. We can't run MUDs, talkers, IRC bots, or other such things here,

because we just don't have the CPU or net bandwidth for them.



- Please keep file transfers and e-mail to less than 100K per day.



- ABSOLUTELY NO BOTS OR BOUNCERS ARE ALLOWED ON GREX. NO EGGDROP!!!

NO PSYBNC!!!



- Please read the Grex list of Frequently Asked Questions. You can see it

on the web at http://www.cyberspace.org/faq.html , or on Grex you can type

"faq" to see it.



Thanks, from all the staff at Grex!

What's happening here?



Hi. I'm a program running on this system. My name is "newuser", and I

am here to help you, the new user, create an account on this system.

After we finish, you will have a public login-id and a private (secret)

password that will uniquely identify yourself to the system. In future

sessions, you'll be able to use that login-id directly rather than me.



I'm going to teach you a very small amount about how to use this system

more effectively. Then I'm going to move on and ask you a couple of

questions. I'll give you a chance to correct your answers, and then I

will craft an account for you (based on your answers). After that, I'm

done, and I'll let you on the system with your new account.



Press ?



The first thing I'm going to teach you about is the special key control-D.



Almost anywhere on the system where you are expected to type a variable

number of lines, you'll end your input by typing control-D after the last

line. Since it's a special key, you don't press or anything

after it. You'll be able to use control-D in just a bit, every time I

give you a chance to answer a question with more than one line.



Press ?



Customizing keys:



Many people like to choose their own keys for the next three functions.

I'm going to tell you some popular choices, and give you a "suggested"

default, but if you can't find them on your keyboard, feel free to pick

any of the popular choices. You shouldn't use letters, numbers, or

punctuation for any of these keys, since that can cause problems

elsewhere on the system.



Also, many computers have cursor keys, function keys, and similar keys

that won't work here, since they actually send more than one character

when you press them.



Press ?



The erase character allows you to remove the last character you typed.

You'll probably want to set it to whatever your "Backspace" or "<--"

key sends; if so, press that key now. Otherwise, press whatever key

you want to use to remove the last character you typed.



If you're not sure what to type here, PRESS YOUR BACKSPACE KEY.



Your current choice for the erase character is '^H'.

Please type that character, or another choice, or '?' for help: ^H

Your erase character is now set to '^H'



The kill character is used to remove the entire line of input you just

typed; sort of like the erase character, but for the whole line. To

set it to control-U, press that key now (hold down "Control" and press

"U", then release both keys). Otherwise, press whatever key you want

to use to remove the entire line of input.



If you aren't sure what to choose, press control-U.



Your current choice for the kill character is '^U'.

Please type that character, or another choice, or '?' for help: ^U

Your kill character is now set to '^U'



The interrupt character allows you to interrupt the current operation

and return to a command prompt. To set it to control-C, press that

key now. Otherwise, press whatever ket you want to use to interrupt

the current operation.



If you aren't sure what to choose, press control-C.



Your current choice for the interrupt character is '^C'.

Please type that character, or another choice, or '?' for help: ^C

Your interrupt character is now set to '^C'



Terminal identification:



There are some programs that need to know how to move the cursor around on

your screen and do various other related things. The software you're

running is probably capable of doing this in several different ways

depending on how you set it up. Since there's no one standard, you need to

tell the system which standard your computer or terminal is using.



If you're using some sort of personal computer (not necessarily an MS-DOS

PC, though), you are probably emulating an ANSI or VT100 terminal; in that

case the "vt100" terminal type is what you want.



Note that the name of your computer won't work, and neither will the name

of the software you're running, because neither one is specific enough.

There are hundreds of different communications software packages out there,

and each one usually gives you a choice of at least five or six different

terminal types. If you have a choice and know how to set it up, you probably

want to choose "VT100" and use the "vt100" or "ansi" terminal types.



Press ?



If you'd like Grex to try to figure out your terminal type for you,

enter "?". Grex will test your terminal type and display the result

on your screen.



If you'd like a list of all 350+ terminals in the termcap database,

enter "??". Feel free to use the interrupt key ('^C') to stop the

list midway though if you see something you like.



Finally, if you're confused by all this, just type vt100

You can change this later once you learn more.



What kind of terminal do you usually use? vt100

Terminal type is vt100



Okay, that completes the "funny key" business. Now it's time for the

question and answer part. The only answer that I need to create your

account is your name; all the other answers are optional. Of course,

all of your answers (especially some of the optional ones) will help us

find out what kind of people are using the system, so we can tailor it

more to your liking. You don't have to make any of this information

public -- I'll ask you whether or not you want your answers to be

available to the other users.



If you ever lose the password to your Grex account and need to have it

reset, the Grex staff will send your new password to the alternate e-mail

address you will be asked to enter a few questions after this one, or to

the postal mail address you enter soon after that. So it is useful to

enter this information. It will be stored in a file called ".plan" in

your Grex account. When the information changes, it's helpful if you

update your .plan file.



Just a reminder, please try to use both upper- and lower-case for text

input; it's much more readable!



Enter your FULL name? belajar



If you so desire, the following information will only be made available

to the system staff. Otherwise, it will be placed in a special file

called a .plan that other users can view when they type a certain command.

I'll ask you to make that decision after I get your answers. Don't

worry about misspellings and such; you'll have a chance to fix any

mistakes you've made after you're done entering the information.



Enter your address?

Terminate your entry with '^D' or "." on a separate line.

>bekasi

>^D



Enter your telephone number: (area)excg-number? 123456789



What other e-mail addresses can you be reached at (if any)?

Terminate your entry with '^D' or "." on a separate line.

>xxxx@yahoo.com

>^D



What is your occupation?

Terminate your entry with '^D' or "." on a separate line.

>IT staff

>^D



What kinds of computer equipment do you use?

Terminate your entry with '^D' or "." on a separate line.

>Pentium

>^D



The next two pieces of information are your birthdate and sex. Feel free

to enter them or not as your feelings dictate.



When were you born? Jakarta



What sex are you? Male



What other interests do you have?

Terminate your entry with '^D' or "." on a separate line.

>Swimming

>^D



How'd you find out about us?

Terminate your entry with '^D' or "." on a separate line.

>internet

>^D

Do you want this information to be hidden from other users? y



You may now pick your command interpreter, or shell. This is the

program that interprets your requests to the system and allows you

to actually do things.



The following shells are available:



bbs - the PicoSpan conferencing system

csh - the C shell

tcsh - an enhanced C shell

sh - the Bourne shell

bash - the GNU version of the Bourne shell

lynx - a fancy menu system. You can select this if you know

what terminal type you are using.

menu - a simple menu system



Unless you're an experienced Unix user, you'll probably want the "bbs",

"menu" or "lynx" shell; it will allow you to start using the system quickly

without mucking around with Unix books and such. If you're not sure

which one to choose, just hit to pick the default ("bbs") shell;

you can always change your mind later.



Which shell? sh



When you want to change some text you've entered while you're typing

it in, the program you use is called an editor. (Editors are similar

to word processors, which you might be familiar with.) Here on Grex

we have several different editing systems you can choose from:



pico This is a simple screen-based editor designed for

new users. If you know what kind of terminal you're

using, you can pick this.

bbs This is the traditional PicoSpan editor. If you

didn't know your terminal type, you should pick this.

joe This is another simple screen-based editor. It's

fairly new on Grex right now.

emacs This is the GNU Emacs editor. If you've never heard

of Emacs or never used it, don't pick this.

vi This is the traditional Unix "vi" editor. If you've

never heard of "vi" or never used it, don't pick this.



If you're not sure which editor to pick, just hit and you

will get the default of "pico".



Which editor? vi



Now, you need to pick a "login-id". This is a short (3-8 characters)

word; it can have lowercase letters and digits in it. Your login-id is

your public identifier on the system; it's what you will type at the

"login:" prompt to identify yourself to the system, as well as what

others will type when they want to send electronic mail to you. It will

also be used in numerous other situations to uniquely identify you.

Because you'll be using it so much, you should pick something that's

relatively easy to type and remember. Many people use their first name,

their initials, their first initial plus their last name, or something

along those lines. This is the name you will be known by, NOT your

password (that comes later)! A few examples:



denise Denise M. Anderson

bubbles Tom Digby



Selecting loginid for belajar



What loginid would you like? belajar



The system will now ask you to pick a secret password.



IMPORTANT:

* Write down your password and login-id somewhere safe. If you forget your

password, you won't be able to use your account anymore. A good place to

write them is on a scrap of paper you keep in your wallet or purse.

* Pick a secure password. Your password should not appear in any list of

words (this includes dictionaries, both English and foreign-language, as

well as lists of names, cities, etc.). Your password also should not be

a word that someone could discover by knowing other things about you --

for that reason, your spouse's name, your pet's name, and your license-plate

number are all bad passwords. The best passwords are made-up words, with

both upper- and lower- case, as well as punctuation and digits.

* Don't share your password with anyone -- not even your closest friends or

family members. If they want to use Grex, encourage them to get their

own account!

* Treat your password like you would a bankcard PIN. Armed with your password

and login-id, someone else can enter responses and send e-mail in your name.

If you think your password might have been compromised, change it immediately

and tell the system staff.



For security reasons, the system will never print your password as you type it.



New password?

Cm'on, you can do better than that!



New password? Reenter just to be sure?

How to make Blog

.:: Tutorial for Beginner ONLY ::. [again ?????.... Please somebody sent me an expert one :) ]

Cara buat Blog



Mungkin dari kita udah pada tahu malahan udah punya beberapa buah blog baik itu di blogger.com atau wordpress.com dan blog-blog lain yang tersebar di internet dan ada sebagian juga orang tidak tahu bagaimana cara buat blog, so kali ini kita akan membahas bagaimana cara membuat blog dengan menggunakan Blogger dengan hasil akhirnya menjadi [namablogkamu.blogspot.com] dan untuk yang pengen buat di wordpress :( Oops.... sorry ane belum buat blog disitu, sebenarnya ada 1 tapi... nggak jelas, nggak ngerti dan terlalu confuse.... :) disamping males buat blog baru.,

ok-lah, langsung aja.kenapa pilih blogger coz salah satunya adalah bawaaan Google so otomatis terindex didalam search engine-nya Mbah Google :) jadi nggak perlu cape'-cape' daftarin kedalam search engine nya... ,disamping kelebihan-kelebihan yang lain.

so... langkah pertama buat blog di Blogger yaitu punya account di Gmail.kalau di wordpress ya Sign In aja. kalau nggak punya, dapat buat account baru nya disini.

selanjutnya go to Blogger.com dan sign in dengan menggunakan account Gmail anda, dan ikutin langkah-langkah yang diinstruksikan [sebenarnya sih nggak payah cuman perlu sedikit bahasa inggris doang, enggak perlu yang expert atau sampe mendetail, cukup sekedar ajah... dijamin pasti udah bisa]

kalau sudah selesai maka akan ada pemberitahuan" you can start posting now"so, let's start writting what you like....terserah, mau letak link-link download[kalau bisa ditulis di blog-nya ntah dibagian mana bahwa blog ini hanya meletakkan link saja bukan software atau pun file-file mp3 lainnya], foto-foto artis dan aktor, artikel, opini, Your Diary, Porn, XXX story..... what ever-lah...

untuk meletakkan acessories [salah ya tulisannya ;) ] pada blog ada di dalam tab layout>add page element, tinggal disesuaikan aja dengan kebutuhan.apa mau meletakkan picture, slide show dan lain-lain.

PS: kalau rajin di update itu blog and sesuai dengan satu topik, nggak "gado-gado" isi posting nya, anda dapat daftarkan blog anda kedalam program ADSENSE [suatu program dari google yang menawarkan Dollar $$ dengan cara menampilkan iklan didalam blog kita, jadi cara kerjanya, barang siapa pengunjung yang meng-click iklan yang ada didalam blog kita maka, kita akan mendapat dollar, eits.... tunggu dulu,jangan main curang dengan meng-click iklan sendiri.... google bakalan tau dan blog anda akan dikeluarkan dari program mereka...[i'm the one who get fuck with this....]

so that's it for today and sorry "NO PICTURE" to describe step by step how to make a blog. For the one who love this blog template i can give you[just for the record, i've change by my self the code on the xhtml and you can upload to overwrite the default code...] enjoy.......

ENKRIPSI

ENKRIPSI DATA

1. Pengertian
Enkripsi adalah suatu metode yang digunakan untuk mengkodekan data sedemikian rupa sehingga keamanan informasinya terjaga dan tidak dapat dibaca tanpa di dekripsi (kebalikan dari proses enkripsi) dahulu. Encryption berasal dari bahasa yunani kryptos yang artinya tersembunyi atau rahasia.

2. Metode yang digunakan.
Umumnya proses enkripsi dilakukan dengan sebuah rumus dan kunci untuk mendekripsi data.
Dalam hal ini, ada beberapa cara melakukan pengamanan data melalui saluran,
salah satu diantaranya adalah kriptografi. Ketika suatu pesan ditransfer dari suatu
tempat ke tempat lain, isi pesan tersebut kemungkinan dapat disadap oleh pihak lain.
Dalam kriptografi, untuk menjaga keamanan pesan, data/ pesan yang dikirimkan
melalui jaringan akan disamarkan (di-scramble/diacak/ diubah menjadi kode yang
tidak dimengerti oleh orang lain) sedemikian rupa sehingga walaupun data tersebut
dapat dibaca, tetapi tetap tidak akan bisa dimengerti oleh pihak yang tidak berhak

Dalam dunia kriptografi, pesan yang akan dirahasiakan disebut plain teks. Pesan
yang sudah diacak disebut cipher teks. Proses untuk mengkonversi plain teks menjadi
cipher teks disebut enkripsi. Proses untuk mengembalikan plain teks dari cipher teks
disebut deskripsi. Algoritma kriptografi (ciphers) adalah fungsi-fungsi matematika yang
digunakan untuk melakukan enkripsi dan deskripsi. Diperlukan kunci yaitu kode untuk
melakukan enkripsi dan deskripsi

Secara umum operasi enkripsi dan dekripsi dapat diterangkan secara matematis
sebagai berikut :

EK (M) = C (Proses Enkripsi)
DK (C) = M (Proses Dekripsi)

Pada saat proses enkripsi kita menyandikan pesan M dengan suatu kunci K lalu
dihasilkan pesan C. Sedangkan pada proses dekripsi, pesan C tersebut diuraikan dengan
menggunakan kunci K sehingga dihasilkan pesan M yang sama seperti pesan
sebelumnya.

Ada dua cara yang paling dasar pada kriptografi klasik.

1. transposisi.

Transposisi adalah mengubah susunan huruf pada plaintext sehingga urutannya berubah.
Contoh yang paling sederhana adalah mengubah suatu kalimat dengan menuliskan setiap
kata secara terbalik.

Plaintext: IBU AKAN DATANG BESOK PAGI
Ciphertext: UBI NAKA GNATAD KOSEB IGAP

Contoh transposisi yang sedikit lebih sulit adalah plaintext yang disusun dalam
kelompok huruf yang terdiri dari beberapa kolom huruf, misalnya 5 kolom huruf :

IBUAK
ANDAT
ANGBE
SOKPA
GIAAA

Plaintext disusun dalam 5 kolom huruf

kemudian dituliskan per kolom, dengan urutan kolom yang bisa berubah-ubah.
IAASGBNNOIUDGKAAABPAKTEAA
Kolom huruf dituliskan berurutan dari kolom 1,2,3,4,5

Cara kedua adalah cara substitusi yaitu setiap huruf pada plaintext akan digantikan
dengan huruf lain berdasarkan suatu cara atau rumus tertentu. Ada dua macam substitusi yaitu
polyalphabetic substitution cipher dan monoalphabetic substitution cipher.
Pada polyalphabetic substitution cipher, enkripsi terhadap satu huruf yang sama
bisa menghasilkan huruf yang berbeda sehingga lebih sulit untuk menemukan pola
enkripsinya.Pada monoalphabetic substitution cipher maka satu huruf tertentu pasti akan
berubah menjadi huruf tertentu yang lain, sehingga pola enkripsinya lebih mudah
diketahui, karena satu huruf pada ciphertext pasti merepresentasikan satu huruf pada
plaintext.

Salah satu contoh cara substitusi adalah dengan dengan pergeseran huruf. Kita lihat
pada gambar 4, urutan abjad ABCD…….Z bisa digeser sebanyak 1 huruf sehingga huruf
A akan menjadi B, B akan menjadi C dan seterusnya. Pergeserannya bisa dibuat lebih
banyak yaitu 2 huruf sehingga huruf A akan menjadi C, B akan menjadi D dan
seterusnya.
Pergeseran bisa lebih banyak lagi tergantung bagaimana kita merumuskannya. Cara pergeseran ini termasuk
monoalphabetic substitution cipher di mana satu huruf pasti akan berubah menjadi huruf tertentu yang lain.
Karena relasi antara huruf plaintext dan huruf ciphertext satu-satu, yang artinya suatu huruf plaintext
pasti menjadi suatu huruf ciphertext tertentu, maka cara monoalphabetic substitution cipher
sangat mudah dipecahkan.

Urutan Abjad : ABCDEFGHIJKLMNOPQRSTUVWXYZ
Pergeseran 1 huruf : BCDEFGHIJKLMNOPQRSTUVWXYZA
Pergeseran 2 huruf : CDEFGHIJKLMNOPQRSTUVWXYZAB

KRIPTOGRAFI CAESAR
Salah satu kriptografi yang paling tua dan paling sederhana adalah kriptogtafi
Caesar. Menurut sejarah, ini adalah cara Julius Caesar mengirimkan surat cinta kepada
kekasihnya Cleopatra. Dalam kriptografi Caesar, maka setiap huruf akan dituliskan
dalam huruf lain hasil pergeseran 3 buah huruf. Kriptografi Caesar ini adalah kriptografi
substitusi karena setiap huruf akan digantikan huruf lain.
Sebagai contoh, huruf A akan digeser 3 huruf menjadi huruf D, B akan digeser 3
huruf menjadi E, J akan digeser menjadi M, O akan menjadi R dan seterusnya.
Pergeseran ini juga berputar kembali ke awal abjad sehingga sesudah huruf Z diikuti
kembali oleh huruf A. Kriptografi Caesar ini dikenal sebagai monoalphabetic
substitution cipher karena satu huruf tertentu pasti akan berubah menjadi huruf
tertentu yang lain.

Cara enkripsi yang paling sederhana adalah dengan mengganti suatu alpabet dengan karakter lain.
Perubahan pada kriptografi Caesar bisa dituliskan sebagai berikut:

Plaintext : ABCDEFGHIJKLMNOPQRSTUVWXYZ
Ciphertext : DEFGHIJKLMNOPQRSTUVWXYZABC

Plaintext :KITA JUMPA BESOK PAGI
Ciphertext :NLWD MXPSD EHVRN SDJL

Plaintext : universitas duta wacana
Kunci : a = b, b = c, c = d, dst
Chipertext : vojwfstjubt evub xbdbob.

Jika Caesar akan menuliskan kalimat ‘I LOVE YOU’ maka akan dituliskan dalam
kalimat ‘L ORYH BRX.


3. Manfaat dan kerugian
Beberapa manfaat yang bisa didapatkan dari enkripsi ini adalah :
a. Kerahasiaan suatu informasi terjamin
b. Menyediakan authentication dan perlindungan integritas pada algoritma checksum/hash
c. Menanggulangi penyadapan telepon dan email
d. Untuk digital signature.
Digital signature adalah menambahkan suatu baris statemen pada suatu elektronik copy dan mengenkripsi statemen tersebut dengan kunci yang kita miliki dan hanya pihak yang memiliki kunci dekripsinya saja yang bisa membukanya.
e. Untuk digital cash

Penyalahgunaan dan kerugian dari enkripsi adalah:

a. Penyandian rencana teroris
b. Penyembunyian record criminal oleh seorang penjahat
c. Pesan tidak bisa dibaca bila penerima pesan lupa atau kehilangan kunci (decryptor).

4. Kesimpulan

Sama seperti teknologi canggih lainnya, enkripsi dapat digunakan untuk mengamankan data bagi perusahaan, militer, pemerintahan, individu untuk tujuan yang baik. Namun enkripsi juga dapat digunakan untuk menyembunyikan informasi bagi para penjahat.

sebenarnya tulisan ini nggak begitu penting bagi yang udah kenal lama dengan yang namanya internet, tapi karena sesuatu dan lain hal yang membuat ane surprise :-o adalah ketika ada yang visit my blog dari feedjit.com yang nge-cari topiknya " Bagaimana cara download menggunakan Internet Download Manager atau IDM" dari search engine google pula tuh.Nah Lho...... :-SS so here is the step by step...


1. kita asumsikan bahwa kita sudah menemukan file yang kita inginkan... entah itu Mp3, e-book, Gambar [*.JPG, *.BMP dll], software, video dalam segala format yang udah pada kita tahu seperti ; *.3gp, *.avi, *.mov, *.dat dan yang lain-lain [ane aja banyak yang nggak tau format video sekarang :-B khusus nya yang support di Phone Cell or HP]

2. buka atau jalankan Internet Download Manager [IDM] atau kalau misal belum ada software nya bisa di download disini (download aja nggak tau.... gimana dunk mas :D , okelah sedikit Out Of Topic [OOT], setelah di click link ini maka akan terbuka halamannya selanjutnya ikutin instruksi yang diminta, kalo nggak salah, disuruh ketik tulisan yang berada didalam kotak, selanjutnya click download.Wuih..... #:-S ] Ok. back on Topic......

3. selanjutnya...... @-) copy link address yang telah diberikan dalam suatu halaman website, biasanya kalau kita arahkan cursor kita maka tulisan nya akan bergaris bawah, INGAT.... hanya jika cursor melewati alamat tersebut, trus tinggal kita perhatikan jenis alamatnya. Mis judul lagu : D'Cinnamond - Selamanya Cinta.mp3, waktu kita arahkan cursor kita ke artis dan judul lagu diatas maka tulisan nya akan bergaris bawah, selanjutnya tinggal kita lihat addres nya di sudut kiri bawah browser yang kita gunakan, ntah itu Mozilla Firefox, Internet Explorer atau browser-browser yang lain, apakah di akhir alamatnya ber-ekstensi Mp3.kalau iya, maka itu file yang kita cari, selanjutnya clak kanan [Oops.... sorry, kebawa kebiasaan di LP3i, soal nya kalau click kanan ya dibilang Clak kanan].dan buka kembali Internet Download Manager [IDM] trus ADD URL dan....... SELESAI... :D

4. untuk beberapa kasus, biasanya file Mp3 yang disediakan berbentuk seperti ini:

Filename [artis-judul lagu]
link [diakhir link berekstensi .mp3]
Note: Right Click on Link and Save target As.... [ini di asumsikan kita nggak pake IDM]

kalau untuk file-file yang lain maka akan berbeda ekstensinya, kalau e-book [*.PDF], software[*.exe atau *.zip itu kalau udah di compress] atau harus di rename menjadi *.mp3 [itu kalau di website nya ada dijelasin " after you download rename it to .mp3] misal hasil yang kita download ber-ekstensi SELAIN .mp3 sebagai contoh kalau kita download dari YOUTUBE

5.Ok.udah Jelas, Nggak, Or Kabur...... you can leave comment or message on ShoutBox or maybe email me.Have A Nice Day... :D

Get access to an UNC at a command prompt (Windows)

pushd \\servername\sharename

The pushd command creates a temporary drive letter that points to the network share, and then changes the command prompt to that drive letter. You can use the pushd command

several times in one session. This creates a list (or "stack") of folders. You can type pushd with no path name to view the current state of the stack.

The popd command returns you to the previous folder, and removes the temporary drive letter that was created by the pushd command.

Repairing Damaged Winsock2

The symptoms when Winsock2 is damaged show when you try to release and renew the IP address using IPCONFIG.
And you get the following error message:
An error occurred while renewing interface 'Internet': An operation was attempted on something that is not a socket.
Also Internet Explorer may give the following error message:
The page cannot be displayed Additionally, you may have no IP address or no Automatic Private IP Addressing (APIPA) address, and you may be receiving IP packets but not sending them.
There are two easy ways to determine if Winsock2 is damaged:
From the XP source files, go to the Support / Tools directory
Winsock Test Method 1
Run netdiag /test:winsock
The end should say Winsock test ..... passed

Winsock Test Method 2
1.Run Msinfo32
2.Click on the + by Components
3.Click on the by Network
4.Click on Protocol
5.There should be 10 sections if the Winsock2 key is ok
MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
MSAFD NetBIOS [\Device\NetBT_Tcpip...
If the names are anything different from those in this list, then likely Winsock2 is corrupted and needs to be repaired.
If you have any 3rd party software installed, the name MSAFD may be changed.
There should be no fewer than 10 sections.

To repair Winsock2

1.Run Regedit
2.Delete the following two registry keys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
3.Restart the computer
4.Go to Network Connections
5.Right click and select Properties
6.Click on the Install button
7.Select Protocol
8.Click on the Add button
9.Click on the Have Disk button
10.Browse to the \Windows\inf directory
11.Click on the Open button
12.Click on the OK button
13.Highlight Internet Protocol (TCP/IP)
14.Click on the OK button
15.Reboot
