We've found one system communicating with the oddly-named '', for instance. Our test laptop occasionally tried to access '', for instance, but as we had the excellent password manager Dashlane installed, that wasn't a surprise.ĭon't recognise the domain? Search for it at Google. Scroll down SmartSniff's capture list and check the domains in its 'Remote Host' column for anything you recognise. But it does give you several ways to figure out more of what's going on. SmartSniff can't associate network traffic with a process, so you're not able to see which application is responsible for any particular internet activity. (Image credit: ) What's using your connection. And SmartSniff has some handy tools to help. What's more interesting is figuring out what all this activity means, what's really going on. You've probably not downloaded SmartSniff just to count packets, though. Our test laptop had Outlook installed, and SmartSniff captured IMAP exchanges, POP3 and more. We saw a lot of conversations with remote websites, but that's just the start. Scrolling through the list gave us more of a feel for what's happening. We closed all browsers on our test system, set SmartSniff running, and in 10 minutes it captured 5,600+ packets across 165 'conversations' (separate exchanges between a process on our PC and a network or internet resource.) To get started, leave SmartSniff running for a few minutes and see just how much network activity your PC has going on in the background. ![]() There's a lot of detail here, but if it's more than you need, click View > Choose Columns and clear the checkboxes for anything you don't want to see. When everything is running smoothly, you'll see internet packets sent by your device, along with their remote IP address and host or domain name, protocol (UDP or TCP), the connection type (HTTP, HTTPS, IMAP, POP3 and others) and a lot more. And if there's still no luck, could you have chosen the wrong adapter? Click Options > Filter Option to check, or maybe try something else. If this doesn't seem to be working, try launching a browser to give the app something to display. You can control this from the toolbar by clicking the green Record button to start capturing traffic, or the red Stop button to, well, stop. Setup complete, SmartSniff should open its main window and begin displaying any network activity. Network traffic can include sensitive data such as usernames and passwords (Image credit: ) Using SmartSniff to monitor Internet traffic To monitor our Wi-Fi traffic we just had to choose the connection name 'WiFi', for instance, while our ethernet adapter was called, you've guessed it, 'Ethernet.' ![]() Our test laptop had lots of these, but most of them could be ignored (anything with a 0.0.0.0 IP address), and the 'Connection Name' column should tell you which adapter to use. Next, choose the network adapter you'd like SmartSniff to monitor. Leave the default 'Raw Sockets' option selected for now (ignore the 'Windows 2000/XP', it also works on everything up to Windows 10.) The first time you launch SmartSniff, it asks you to choose a Capture Method. If you're not sure which version you need, grab the installer. Just download and unzip it, then run the SmartSniff executable, smsniff.exe. ![]() If you're running a modern Windows 10 PC then the 64-bit version is best. Scroll to the bottom of the SmartSniff website page and you'll find it comes in three download flavors: a plain ZIP file, a 64-bit build, and a version with an installer which covers everything.
