![]() This is one way to make capture easier, by the way. ![]() I was able to read the file, as well as see the available capture interfaces: I ran Wireshark from the Terminal - sudo wireshark. This means that the file created will also be only accessible with elevated permissions. When dumpcap was ran, it was elevated - remember the sudo prefix. A problem appeared when I tried to open the file, however. The file that is captured is a PCAP-formatted entity, so it can be easily analyzed in Wireshark. In my case, the computer was connected to a wireless network, so I had to monitor the wlan0 interface. That will give you a list of registered interfaces. To make sure that you are capturing on the right one, use the ifconfig command. Depending on individual system configurations, there might be a different number of network interfaces. Open the Terminal (Ctrl+ALT+T) and type in dumpcap -i NAME_OF_THE_INTERFACE. So what are the options?įirst and foremost it is still possible to use the dumpcap tool. When Wireshark is running outside the administrative sandbox, without root permissions, it won’t allow the user to capture data on any of the registered network interfaces. With a little research, I found out that it is, in fact, a built in restriction. There are no interfaces I could capture data on. I downloaded Wireshark, but was greeted with this: Ubuntu is a new environment for me, and I figured that the actual capture process is set a bit differently. I worked with this kind of tasks on Windows, and got some pretty interesting results by sniffing Windows Phone, Xbox and Windows 8 traffic with Wireshark. ![]() ![]() Setting Up A Network Capture Box With Ubuntu And Wireshark It's easier than you think to set up a machine for network traffic capture and analysis.įor a college project I had to set up an Ubuntu box and work on a network analysis assignment. ![]()
