A port scanner is a tool that scans a server for open ports, and a port weeping is the act of scanning a range of IP addresses for a specific “listening” port number. This can be a useful way of locating certain types of servers, such as FTP servers, for example.

If you are aware of the existence of an FTP server on a certain IP range, but do not know the exact address, Angry IP Scanner can be used to fill in the blanks by scanning that range of addresses within a very short space of time.

Step-by-Step Instructions

• Access the related download link for this article and grab the executable launcher for Angry IP Scanner. The program requires no installation and is run simply by executing the file ip_scan.exe. Once the tiny download has completed, access your downloads folder and run this file to start Angry IP Scanner. The small application window appears after a brief pause.
• Note the IP Range field is pre-populated with your own internal network address when Angry IP Scanner first launches (this probably starts with 192.168). In this field, enter the starting address of the IP address range you want to scan, for example, 213.167.1.1.
• In the “to” field, enter the ending address of the IP range, e.g. 217.167.1.1. This means all the possible IP addresses between 213.167.1.1 and 217.167.1.1 will be scanned for the port number you specify.
• Click Tools and Preferences. In the Scanning tab, set the Delay to 20ms and the maximum number of threads to 10000.
• In the Ports tab, enter 21 in the port selection tab (21 is the default port number for FTP servers).
• In the Display tab, select Hosts with open ports only. Click OK to close the preferences window.
• Click Start to begin scanning the specified range of IP addresses. After a short time (which depends on the size of the IP range), a list of results is displayed. These IP addresses all contain the open port number you specified.

Tips & Advice

• Once the list of IP addresses is displayed, you can use the built in FTP feature of Angry IP Scanner to browse one of the servers. Right-click any address and choose Open then FTP. You will then be prompted to enter your username and password (if the server has security).
• Never use Angry IP Scanner to detect the IP addresses of FTP servers you have not been granted access to, as this is illegal in most countries.

Push Email, the ability to automatically be notified of new mail items arriving on a mobile handset (without having to open a mail application and fetch items manually), exploded in popularity in 2007 with the arrival of the Apple iPhone. Now, it is considered fairly standard practice for business and casual users to be able to receive and reply to email on the move, and today thousands of handsets much cheaper than the iPhone also support this facility out-of-the-box.

If you are lucky enough to have an iPhone, and your company utilises a Microsoft Exchange server for its email, then you too can become a part of this revolution. The iPhone comes with a built in wizard that makes it easy to configure the device for access to email on the move.

You will need: an iPhone (3 or 4), a mailbox account (and credentials) for a hosted Exchange server

Step-by-Step Instructions

• Tap the Settings icon on your Apple iPhone and then Mail, Contacts, Calendars. Tap Add Account and then Other.
• Enter the following information:
  Name – enter your full names, first and last, exactly how you want it to appear on the screen when a recipient opens one of your emails.
  Address – enter your complete email address for Exchange account.
  Password – enter the password for the Exchange account.
  Description – enter a meaningful name for the account. The iPhone lets you configure multiple accounts up on the device and you will want to ensure you can easily identify each one to avoid confusion.

  Tap Save when you have entered all the above information.

• On the next screen, select IMAP or POP, depending on what information has been supplied to you by the Exchange server administrator. Enter the following for both the Incoming Mail Server and Outgoing Mail Server:
  Host name – enter the name of the secure email server, e.g. mail.securedomain.com.
  User name – enter your complete email address for Exchange account.
  Password – enter the password for the Exchange account.

  Tap Save again after entering all the above information. You are returned to the Mail, Contacts and Calendars screen. Tap the newly created mail account.

• At the bottom of the screen, locate and tap Advanced. It might be necessary to ensure the folders on the server are correctly mapped with those on your device (sometimes differences in naming conventions, such as Deleted  and Trash, can cause problems).
• Select Mailbox Behaviours and check the folder names in bold are mapping to the folder names in blue. If there are any mismatches, tap the arrow alongside the blue folder name and select the correct folder to map it to.

  You should now be able to receive email sent to your Exchange account on your iPhone. You can test this has been set up correctly by sending yourself an email from your computer. If your Exchange server supports Push notifications, the new email will arrive on your computer and iPhone almost simultaneously.

Tips & Advice

• If your iPhone is set up to send and receive confidential business emails, ensure you use appropriate security measures. Keep the handset locked with a PIN when not in use.
