NetworkTopology - choose the right place in your network topology in order to get the required network traffic. Make sure you capture from a location in the network where all relevant traffic will pass through: In this step: Capture traffic that is not intended for your local machine. Make sure you've finished step 3 successfully! Step 4: Capture traffic destined for machines other than your own Try to capture using TcpDump / WinDump - if that's working, it's a Wireshark problem - if not it's related to libpcap / WinPcap or the network card driver.

If you still experience a problem after checking the above you may try to figure out if it's a Wireshark or a driver problem. Performance - what you can do if packet drops occur No traffic - make sure you don't capture on a "silent" network with no traffic on it (if you really don't have any traffic: using an internet radio is a simple traffic generator) Offloading - how your NIC might skew your capture VPN / (personal) firewall software) may cause trouble

InterferingSoftware - low level networking software (e.g. Promiscuous mode - try both on or off, whatever works NetworkMedia - there might be network media ( /Ethernet, /PPP, …) specific limitations NetworkInterfaces - make sure that you've selected the right interface Have a look at the captured packets and make sure you have captured both incoming and outgoing traffic before going to the next step! To avoid any side effects, don't use any shiny features like capture filters or multiple files for now.Īt least after stopping the capture you should see some network traffic now! The traffic to and from your local machine is obviously available independent of your network topology, so you don't need to worry about the topology for now.Ĭhoose the right interface to capture from (see /NetworkInterfaces) and start a capture. In this step: Capturing "your own local traffic" is the easiest way to successfully capture your first traffic. Step 3: Capture traffic "sent to" and "sent from" your local machine User's Guide about Time Zones your computer's time and time zone settings should be correct, so the time stamps captured are meaningful capture support is enabled / a capture driver is installed

CaptureSupport - your operating system must support packet capturing, e.g. special privileges allowing capturing as a normal user (preferred) or root / Administrator privileges CapturePrivileges - you must have sufficient privileges to capture packets, e.g. In this step: Setup the machine's configuration to be able and allowed to capture.

If you have to change network cabling to start a capture, ensure that you are allowed to do so! Network administrators and other people are usually not amused with re-arrangements to "their" network. In this step: Make sure you're allowed to do what you're going to do!Įnsure that you are allowed to capture packets from the network you are working on! For example, corporate policies or applicable law might prevent you from capturing on the network you're using! Step 5: Capture traffic using a remote machine.Step 4: Capture traffic destined for machines other than your own.Step 3: Capture traffic "sent to" and "sent from" your local machine.
