There are two ways to disable overlay-scrollbar in Wireshark, depending on how you launch Wireshark on your desktop. It is known that Wireshark's UI, especially run under Ubuntu desktop, sometimes hangs or freezes with the following errors, while you are scrolling up or down the packet list view, or starting to load a pre-recorded packet dump file.Īpparently this error is caused by some incompatibility between Wireshark and overlay-scrollbar, and has not been fixed in the latest Ubuntu desktop (e.g., as of Ubuntu 15.04 Vivid Vervet).Ī workaround to avoid this Wireshark UI freeze problem is to temporarily disabling overlay-scrollbar. Wireshark allows one to capture live packets and browse their protocol headers and payloads via a convenient GUI. This tool is popularly used by network administrators, network security engineers or developers for various tasks where packet-level network analysis is required, for example during network troubleshooting, vulnerability testing, application debugging, or protocol reverse engineering. Wireshark is a GUI-based packet capture and sniffer tool.
