SmartSniff v1.51 - Freeware TCP/IP Packet Sniffer
Description
SmartSniff is a network monitoring utility that allows you to capture TCP/IP packets that pass through your network adapter, and view the captured data as sequence of conversations between clients and servers. You can view the TCP/IP conversations in Ascii mode (for text-based protocols, like HTTP, SMTP, POP3 and FTP.) or as hex dump. (for non-text base protocols, like DNS)SmartSniff provides 3 methods for capturing TCP/IP packets :
- Raw Sockets (Only for Windows 2000/XP or greater): Allows you to capture TCP/IP packets on your network without installing a capture driver. This method has some limitations and problems.
- WinPcap Capture Driver: Allows you to capture TCP/IP packets on all Windows operating systems. (Windows 98/ME/NT/2000/XP/2003/Vista) In order to use it, you have to download and install WinPcap Capture Driver from this Web site. (WinPcap is a free open-source capture driver.)
This method is generally the preferred way to capture TCP/IP packets with SmartSniff, and it works better than the Raw Sockets method. - Microsoft Network Monitor Driver (Only for Windows 2000/XP/2003): Microsoft provides a free capture driver under Windows 2000/XP/2003 that can be used by SmartSniff, but this driver is not installed by default, and you have to manually install it, by using one of the following options:
- Option 1: Install it from the CD-ROM of Windows 2000/XP according to the instructions in Microsoft Web site
- Option 2 (XP Only) : Download and install the Windows XP Service Pack 2 Support Tools. One of the tools in this package is netcap.exe. When you run this tool in the first time, the Network Monitor Driver will automatically be installed on your system.
Notice:If WinPcap is installed on your system, and you want to use the Microsoft Network Monitor Driver method, it's recommended to run SmartSniff with /NoCapDriver, because the Microsoft Network Monitor Driver may not work properly when WinPcap is loaded too.
System Requirements
SmartSniff can capture TCP/IP packets on any 32-bit Windows operating system (Windows 98/ME/NT/2000/XP) as long as WinPcap capture driver is installed and works properly with your network adapter.Under Windows 2000/XP (or greater), SmartSniff also allows you to capture TCP/IP packets without installing any capture driver, by using 'Raw Sockets' method. However, this capture method has some limitations and problems:
- Outgoing UDP and ICMP packets are not captured.
- On Windows XP SP1 outgoing packets are not captured at all - Thanks to Microsoft's bug that appeared in SP1 update...
This bug was fixed on SP2 update, but under Vista, Microsoft returned back the outgoing packets bug of XP/SP1. - On Windows Vista with SP1, only UDP packets are captured. TCP packets are not captured at all.

Windows 7
http://www.microsoft.com/windows/windows-7/features/whats-new.aspx
Improved taskbar and full-screen previews
The taskbar at the bottom of your screen is what you use to launch programs and switch between them when they're open. In Windows 7 you can pin any program to the taskbar so it’s always just a click away, and you can rearrange the icons on the taskbar just by clicking and dragging. We’ve made the icons considerably bigger, too, so they’re easier to use. Hover over the icons and you’ll see thumbnails of every file or window that open in that program, and if you hover over the thumbnail, you’ll see a full-screen preview of that window. Move the cursor off the thumbnail and the full-screen preview disappears.

Move the cursor off the thumbnail and the full-screen preview disappears.
Jump Lists
With Windows 7, we focused on keeping the things you use most right in front of you. One example: The new Jump List feature. It's a handy way to quickly reach the files you've been working with. To see the files you've used recently, just right click on the icon on your taskbar. So right-clicking on the Word icon will show your most recent Word documents. Plus, if there are other files you want to keep handy, you can just pin them to the Jump List so they’ll always appear. That way, the documents you’re likely to want are just a couple clicks away.
Some programs, such as Windows Media Player, can pre-populate their Jump Lists with common tasks. For example, on the Jump List for Windows Media Player, you’ll see options to Play All Music or resume your last playlist. On the Jump List for Internet Explorer, you’ll see frequently and recently viewed websites. With some programs, you’ll even have quick access to tasks that, in the past, were only available from within the program, such as composing a new e-mail message.

Instant Search
To start, as you type a search request you'll immediately start seeing relevant suggestions from your chosen search provider, complete with images when available. The twist: search will also use your browsing history to narrow the suggestions. If you see what you're looking for, you can go right to the list without finishing the request.
Accelerators
There are online services you use all the time. Like mapping a location. With Accelerators, you can highlight a bit of information on any page, click on the blue Accelerators icon, and choose from a variety of relevant services. So if you highlight a street address and right click, the Live Maps Accelerator will show a map preview right there on the page. In addition to mapping, you’ll find Accelerators for e-mailing, blogging, searching, translating, and sharing information. Popular services including eBay and Facebook offer special Accelerators you can use with their sites.

Web Slices
A Web Slice is something you use when you need to track information on a website, but you don’t want to keep going to the site. Use a web slice for things like auction items, sports scores, entertainment columns, and weather reports. When the content you're watching changes, you’ll see it right away in the Web Slice in your Favorites Bar.
Better device management
One of the great things about PCs is how they let us use such a wide array of devices. In the past, you had to use several different screens to manage different types of devices. But With Windows 7, you'll use a single Devices and Printers screen to connect, manage, and use whatever printers, phones, and other devices you have on-hand.

HomeGroup
Today, you may have a network in your home that you use to share an internet connection. But it can be hard to share other things, like files and printers. Do you have one or more computers in your home but only one printer? If you’re like most people, when you need to print a file that’s on your laptop in your bedroom on the printer in your den, you probably e-mail the file from one PC to another or transfer it on a USB drive. And if you need to find a file but don’t know which computer it’s stored on, chances are you’re in for a long night as you traipse from PC to PC and search each one.
HomeGroup, a new feature in Windows 7, makes connecting the computers in your home a painless process. HomeGroup is set up automatically when you add the first PC running Windows 7 to your home network. Adding more PCs running Windows 7 to the HomeGroup is an easy process. You can specify exactly what you want to share from each PC with all the PCs in the HomeGroup. Then, sharing files across the various PCs in your home—and many other devices—is as easy as if all your data were on a single hard drive. So you can store digital photos on a computer in your den and easily access them from a laptop anywhere in your home. Similarly, once in a HomeGroup, the printer in your den is shared automatically with all of the PCs in your home.

Decide whether to join an existing network
Easily explore content on other devices on the network
View Available Network (VAN)
Windows 7 makes viewing and connecting to all of your networks simple and consistent. You'll always have one-click access to available networks, regardless of whether those networks are based on Wi-Fi, mobile broadband, dial-up, or your corporate VPN.

Oracle bought Sun
http://www.oracle.com/us/corporate/press/018363
Questions:
1. What do you think is the effect of Oracle buying Sun?
Oracle’s announcement yesterday that it plans to acquire Sun Microsystems for $7.4 billion or about $9.50 per share of Sun common stock in cash shocked much of the tech industry. Ellison and company are clearly looking at the possibilities of marrying key software to some of Sun’s key hardware on the database side.
An interesting note from a conference call question was that Oracle President Safra Catz said that Oracle believes it can run Sun at substantially higher margins. It is not clear exactly how Oracle could do that without cutting costs associated with Sun projects.
2. What do you think would Bill Gates do about this?
3. To you as a student using Java, how will this later affect your learning on the language?
