Monitor and save your network traffic

SmartSniff is a tiny packet sniffer which tries to capture and display the TCP/IP packets that pass through your chosen network adapter.

The program can work with Microsoft Network Monitor Driver and WinPcap, but can also work with raw sockets if you've nothing else installed.

To get started, open the program, click the green "Play" button on the toolbar and select the network adapter to use.

Any background network packets will be captured and various details displayed: protocol, local and remote addresses/ ports/ hosts, service name, data size, capture time, local and remote MAC address, local and remote IP country, and more.

Send an email, open a browser, visit a website or two and more traffic details should appear.

Once you've finished, click "Stop" to stop capture.

Browse down the list to look for interesting packets, perhaps based on the remote host name. Click on any item and the lower pane shows you its contents in either text or hex form.

If this was a POP3 packet, for instance, you might see user names and passwords travelling over the network in plain text.

Browsing down the list, we noticed an odd host name we didn't recognise, clicked the packet and found text showing it related to our antivirus package.

There are a huge number of display and capture options, including the ability to filter traffic by protocol and port.

You can also export the table as an HTML report, or save the captured packets for analysis somewhere else.

Version 2.26:

- SmartSniff now automatically loads the new version of WinPCap driver from if it's installed on your system.
- SmartSniff now tries to load the dll of Network Monitor Driver 3.x (NmApi.dll) according to the installation path specified in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Netmon3. This change should solve the problem with loading the Network Monitor Driver 3.x on some systems.


An excellent packet sniffer, compact, portable and highly configurable.

WhatsApp Messenger 2.17.61

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.17.61

- Search messages within a specific chat: Open any chat, tap the chat name at the top to go to Contact Info/Group Info, and then tap Chat Search.
- Design improvements for iOS 11.
- Post text-only updates to your status and they'll be visible for 24 hours. Just tap the pencil icon in the Status tab, type what you'd like to share, and pick a background color or font.
