  Rename start button

  Blogging, Uncategorized, Windows Web Hosting No Comments

  To rename the start button, you will need a hex editor. My preference is UltraEdit

  1. Copy the \windows\explore.exe file to a new name (e.g. explorer_1.exe)

  2. With the hex editor, open that file and go to offset 412b6

  3. You will see the word start with blanks between each letter

  4. Edit it be any 5 characters or less

  5. Save the file

  6. Boot to DOS

  7. Copy the existing c:\windows\explorer.exe to explorer.org

  8. Copy explorer_1.exe to explorer.exe

  9. You will also need to replace the explorer.exe in the c:\windows\system32\dllcache file as well with the new one. Note: If the partition is NTFS and you can’t access the files from DOS: 1. Start Regedit 2. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon. 3. Change the value of Shell from Explorer.exe to explorer_1.exe

  Enjoy..

  Tips and tricks for internet exporer

  Blogging, Internet Security, Web Hosting Articles No Comments

  Greetings,

  Most people use Internet Explorer to browse the net. It loads up fast because parts of it is loaded by Windows as the latter boots up. Using the feedback from its huge user base, Microsoft has made numerous improvements, which you can use to your advantage.

  • Disable the Links toolbar and save space. Remove the Explorer view for the same reason.

  • Customize the toolbar via View » Toolbars » Customize.

  • Blank home page: Set your home page to a blank one so that it loads up faster. This is done via Tools » Internet Options » General » Use Blank.

  • Offline browsing:You do not have to connect to the Internet to revisit a page. You can access it from the cache. This is done via Tools » Internet Options » Temporary Internet Folders » Settings » Check newer versions of stored pages: » Never. After setting up IE like this, you can browse offline by, click on the History button. This will open up the History folder in a left pane. Browse through this to access the pages that you have visited earlier. You check the latest version on the net however by clicking on the Refresh button.

  • Computer Security: Some websites have ads that tell you that your computer could be transmitting vital/private information about you, which could be targeted by hackers and viruses. They will tell you to download a security software. Considering the fact that they are using wrong tactics to sell their product, it is quite possible that their software could be doing more harm than good. No matter which software you use, it is not possible to completely hide your computer on the net. People who have always-on Internet connections like broadband or cable should instead use firewalls like the trusty ZoneAlarm or Tiny.

  There are other websites that will ask visitors to install ActiveX controls like Gator or Bonzi. These are spyware and Internet users should avoid them.
  Neither should you install programs like MP3 Dancer. These are spyware. Even if you uninstall them, they will still remain on your computer without your knowledge.

  • Tip 1: IE’s autocomplete feature may throw up some web addresses at the address bar, which you may not want others to see. So, clear the history. This is done by Internet Options » Clear History. If otherwise you want to selectively remove history items, then delete the appropriate folders inside the History folder. In Windows 9x/Me, the History folder is inside the Windows folder. In Windows 2000/XP, it will be inside the Documents and Settings\«User name»\Local Settings\ folder.

  • Tip 2: Deleting the files in the Temporary Internet Files folder can remove only part of your tracks. Cookies stored by websites usually remain in this folder with their full web address. So, that is a security violation. To remove them, choose Internet Options » Temporary Internet Folder » Delete Cookies.

  • Tip 3: All evidence is still not removed. There is a file inside the Temporary Internet Files folder called index.dat, which has some evidence of your browsing history. Delete this file too. IE will regenerate another index.dat later.

  • Paranoia 4: When the Autocomplete feature is enabled, all your personal information including passwords are stored on the computer, which is available for others to misuse. So, when you are done with browsing at your office or an Internet cafe, follow the above three steps and clear the saved data by choosing Internet Options » Content » AutoComplete » Clear Forms and Clear Passwords. Sometimes, the Internet Options menu option might be disabled in your office or web cafe. So, delete the HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms key from the registry. If you want to steal or backup passwords, export this key and import it on a different machine or installation. You will also have to copy the {username}.pwl file and cookies to the new machine/installation. Sometimes, there are ActiveX programs that sit silently recording everything. You can check them out at Internet Options » Temporary Internet Files » Settings » View Objects. This will open the Downloaded Program Files folder in the windows folder. By right-clicking the contents, you can either remove them or check out their properties.

  • Tip 5: In certain Internet cafes, silent keyboard loggers are installed by certain people to collect userids and passwords, and send them to their email addresses. Remove these programs from memory and only then browse. Also disable form fillers such as Gator in Internet cafes.

  • Downloading recalcitrant files: Most people use a downloaded manager to download huge files. But, sometimes they run into problems when the download manager is not able to catch the correct url of the file. In such cases, open the source of the page via View » Source and do a search for the download file. Usually, the full url of the file will be found here. Copy this and paste it in the download manager. If some website prevents you from right-clicking to save an image on it, just look inside the Temporary Internet Files folder for it.

  • IE Toolbars : Add the Google toolbar to IE. With this toolbar, you will get to the results without having to visit Google’s home page first.

  • ESCAPE: Many people do not know this. If a page is being downloaded and you want to stop it, then pressing the Escape key will do that. Also, pressing Backspace key will take you to the previous page.

  • Saving web pages: Beginning with Version 5, IE allows saving a web page in a single file including its images and other embedded content. To do this, choose Save As from the File menu. Here in the Save as type, choose Web Archive, single file (*.mht). Sometimes, MHT files may not show anything even though its thumbnail does show something. If you disable Javascript, you will be able to see the whatever something you saw in the thumbnail.

  EPP / Authorization key…

  Uncategorized No Comments

  * ” What is an EPP Code/ Authorization key ? “

  EPP stands for Extensible Provisioning Protocol: An application layer client-server protocol for the provisioning and management of objects stored in a shared central repository. Specified in XML, the protocol defines generic object management operations and an extensible framework that maps protocol operations to objects.

  This method is used to verify .org, .info, .biz, .us, .cn, .com.cn, .net.cn, .org.cn, .cn, .tw, .jp and .in domains only. This may change at any time depending upon registry requirements.

  When an EPP transfer order is created, an “authorization key” or “EPP key” is required for each domain name to be transferred. Per ICANN regulations, a verification email or fax transfer authorization is also required.

  Authorization (or EPP) keys/codes are generated by the current registrar and verified through the global registries for validity.

  Although some registrars have begun to implement the EPP security protocol for .com and .net domains, the global registry, (Verisign) does not yet require an EPP/authorization key for registrar transfer of these TLD’s. Until EPP authorization is mandated by the registry,requirements for transferring your .com and .net domains to or away from eNom have not changed.

  Until this functionality has been fully employed, you will NOT be asked for an EPP key to transfer your .com or .net domain to or away from eNom. Some EPP enabled registrars may state that they require an EPP/authorization key for registrar transfer. In these cases, the domain owner has to contact the current domain registrar and request for the EPP/authorization key. A EPP/authorization key is a combination of alpha-numeric characters.For Example : A ” made up “ EPP key** would look something like this: X9S03ZQ5490KJ32AM.

  NOTE: Authorization (EPP) keys are a security code required by the registry for domain transfer, thus are unique to every domain name. No two EPP/authorization keys are the same, thus if you are transferring more than one EPP domain, you will need to obtain each domain’s specific code.

  Domain Redemption Period

  Uncategorized 1 Comment

  What is a Redemption Period?

  
  The redemption period is known as ” grace period ” for upto 30 days that once a domain registrar deletes a domain name after the domain expiration date , the domain owner still has a validity for 30 days to gain the same domain. This deletion normally occurs sometime within the first 45 days after a name expires without being renewed.

  Instead of actually being deleted and re-available for registration within a few days, what happens is the central VeriSign registry holds the name in a new “REDEMPTIONPERIOD” status. The grace period basically gives the original domain owner a chance to renew their domain name.

  After the Expired period, a domain goes into a second stage called the redemption (or On Hold) period. For 30 days, the original domain owner still has the option to renew the domain, but must also pay a $175 fine.

  Cryptography

  Customer Service, Internet Security, Server Security, Uncategorized No Comments

  Hello friends,

  What is cryptography ?

  Cryptography is the study of message protection in secret format. To most people, cryptography is concerned with keeping their communications private and secrete. The protection of sensitive communications has been the emphasis of cryptography throughout much of its history

  There are two kinds of cryptography : symmetric and asymmetric. Symmetric cryptosystems use the same key (the secret key) to encrypt and decrypt a message, and Asymmetric cryptosystems use one key (the public key) to encrypt a message and a different key (the private key) to decrypt the encrypted message. Assymetric cryptosystems are also called public key cryptosystems.

  Encryption is the transformation of data or message into a form that is as close to impossible as possible to read without the appropriate knowledge (a key; see below). Its purpose is to ensure privacy by keeping information hidden from anyone or unauthorise person, even those who have access to the encrypted data. Decryption is the reverse of encryption; it is the transformation of encrypted data back into an intelligible form.

  Authentication is as fundamentally a part of our lives as privacy. Authentication is very necessary in our day to day life with any kind of transactions- when we sign our name to some document for instance - and, as we move to a world where our decisions and agreements are communicated electronically, we need to have electronic techniques for providing authentication. Cryptography provides mechanisms for such procedures. A digital signature.

  Cryptography is central to the techniques used in computer and network security for such things as access control and information confidentiality. Cryptography is also used in many applications encountered in everyday life; the security of ATM cards, computer passwords, and electronic commerce all depend on cryptography.

  TCP/IP Application Protocols

  Dedicated Server Hosting, Domain Name, Server Security, Web Hosting Articles No Comments

  Following are the TCP/IP Application protocols:
  1.DHCP:

  DHCP Dynamic Host Configuration Protocol is defined by RFC’s 2131
  and 2132.DHCP is Dynamic Host Configuration
  Protocol (DHCP) allows IP addresses to
  be allocated to hosts on an as-needed basis.DHCP lets a host
  ‘borrow’ an IP address from a pool of IP addresses; when the
  address is no longer required it is recycled and made available for
  use by other host. DHCP also allows a host to retrieve a
  verity of configuration information.

  DCHP depends on UDP to carry packets between the client and server
  tasks.

  2. DNS

  The DNS (Domain Name System) provides ondemand dynamic
  translation between human-readable names (like www.mydoamin.com)
  and the numeric addresses actually used by IP (like
  192.169.10.28). The basics of DNS operation are defined in RFC’s
  1034, 1101, 1876, 1982 and 2065.

  A very widely-used implementation of DNS called BIND
  (Berkeley Internet Name Domain)
  DNS uses both UDP and TCP. It used UDP to carry simple queries and
  responses but depends on TCP to guarantee the correct and orderly
  delivery of large amounts of bulk data (eg zone configurations) across the network.

  3. FTP

  File Transfer Protocol (FTP) provides a mechanism for transfering data
  files between various systems. In addition to the fundamental PUT and GET
  operations, FTP provides a small number of file management and
  user authentication facilities. FTP uses port 21

  FTP depends on TCP to guarantee the correct and orderly delivery
  of data across the network.

  4. HTTP

  Hyper Text Transfer Protocol (HTTP) is the protocol used to publish
  Web pages across an internet. HTTP depends on TCP to guarantee the
  correct and orderly delivery of data across the network.

  5. IMAP

  Interactive Mail Access Protocol (IMAP) allows clients to
  manipulate email messages and mailboxes that reside on some server
  machine. The current version of IMAP is Version 4, IMAP is more powerful
  and more complex than the other widely-used mail-reading protocol
  POP.

  6. NFS

  Network File System (NFS) allows files stored on one machine (the
  “server”) to be accessed by other machines (the “clients”) as
  though the files were actually present on the client systems. NFS
  is defined in terms of a Remote Procedure Call (RPC) abstraction
  which in turn formats its packets according to a
  processor-independent eXternal Data Representation (XDR).

  NFS is most often used over UDP. UDP does not guarantee packet delivery or ordering, so
  when NFS runs over UDP the RPC implementation must provide its own
  guarantees of correctness.

  7. NNTP

  Network News Transfer Protocol (NNTP) is used to propagate netnews
  postings (including Usenet postings) between systems.

  8. NTP

  Network Time Protocol (NTP) is used to synchronise time-of-day
  clocks between various computer systems. The current version of
  NTP is Version 3, defined in RFC 1305.

  9. POP

  Post Office Protocol (POP) allows clients to read and remove email
  from a mailbox that resides on some server machine. The current
  version of POP is Version 3, usually referred to as POP3. POP uses port 110

  10. Rlogin

  Remote Login (rlogin) provides a network terminal or “remote
  login” capability. Rlogin is similar to Telnet but it adds a
  couple of features that make it a little more convenient than
  Telnet.

  11. Rsh

  Remote Shell (rsh) is an r-command that provides for remote
  execution of arbitrary commands. It allows you to run a command on
  a server without having to actually log in on the server. More
  importantly it allows you to feed data to the remote command and
  retrieve the command’s output without having to stage the data
  through temporary files on the server.

  12. SMTP

  Simple Mail Transfer Protocol (SMTP) is used to deliver email from
  one system to another. The port used by SMTP is 25.
  13. SNMP

  Simple Network Management Protocol (SNMP) provides a means of
  monitoring and managing systems over a network. SNMP defines a
  method of sending queries (the GET and GET-NEXT primitives) and
  commands (the SET primitive) from a management station client to
  an agent server running on the target system, and collecting
  responses and unsolicited event notifications.

  14. Ssh

  Secure Shell (ssh) provides remote login and execution features
  similar to those of the rsh and rlogin r-commands, but ssh
  encrypts the data that is exchanged over the network. Encryption
  can protect sensitive information, and it is not uncommon for
  security-conscious administrators to disable plain rsh and telnet
  services in favour of ssh.

  The SSH protocol used by the ssh command has also been used to
  build a secure file transfer application which can be used as an
  alternative to FTP for sensitive data.

  15. Telnet

  Telnet provides a network terminal or “remote login” capability.
  The Telnet server accepts data from the telnet client and forwards
  them to the operating system in such a way that the received
  characters are treated as though they had been typed at a terminal
  keyboard. Responses generated by the server operating system are
  passed back to the Telnet client for display.

  16. X Window System

  The X Window System allows client programs running on one machine to control the graphic
  display, keyboard and mouse of some other machine or of a
  dedicated X display terminal.

  enjoy…..:)

  Protocol stack (TCP/IP)

  Blogging, Internet Security, Uncategorized 1 Comment

  The protocol Stack:
  In TCP/IP’s most basic level, a computer network is simply a series of connections between computers which allow them to communicate. The scope, size, speed, content and reliability of the network depending on its protocols suite and implementation. Protocols are pre-established means of communication. The term TCP/IP (Transmission Control Protocol/Internet Protocol) actually refers to a whole family of protocols, of which TCP and IP are just two. Following figure contains the standard “stack” diagram of TCP/IP. Rather than make protocols monolithic (which would mean ftp, telnet, and gopher would each have a full network protocol implementation, including separate copies of kernel code for the devices each protocol uses), the designers of TCP/IP broke the job of a full network protocol suite into a number of tasks. Each layer corresponds to a different facet of communication. Conceptually, it is useful to envision TCP/IP as a stack. In implementations, programmers often blur the layers for increased performance.
