Better way: Install Wireshark, if you haven’t already.Doing so provides full root privileges to both ostinato and drone which is unnecessary and insecure. Easy way: Use sudo /Applications/Ostinato/Ostinato.app/Contents/MacOS/Ostinato.Mac OSX: There’s an easy way and a better way.After doing that you can run ostinato as a normal user Better way: Do a one-time privilege assignment.Doing this provides full root privileges to both ostinato and drone which is unnecessary and insecure. Easy way: If your distro supports sudo use sudo ostinato, otherwise become root by doing su and then run ostinato.Linux: There’s an easy way and a better way.Ensure that drone is running with required privileges.Check that ports are not administratively disabled.Verify that the port group status is “connected” (the port group icon is green).If drone is not running, try running drone manually. If yes, try reconnecting to the port group (File | Connect Port Group) - make sure that the firewall is not blocking TCP port 7878. I cannot connect to the port groupĬheck if drone is running. See I cannot connect to the port group Q. After starting Ostinato, the port group status is disconnected (the port group icon is red) Note: Although Drone can be invoked without sudo or as root, it will run with the privileges you assigned to it by one of the above methods. Post this setup, you should be able to run Ostinato/Drone as a normal user without using sudo or as root. Run the following via sudo or as root -Įither of these methods, need to be done only once. If you are using Linux, and your distro provides the setcap utility to set capabilities, you can assign just the required network privileges to the drone binary instead of full root privileges. You can find the path for your system by running which drone after installing the package. Please use the path appropriate for your system when running these commands. Some distros may install it at /usr/local/bin or /bin. The below commands assume drone was installed in /usr/bin. Only the drone agent requires special privileges, not the controller (See Controller-Agent Architecture). I don’t like running Ostinato/Drone as root. You have WinPcap installed (Windows Only).The drone executable is in the same path as ostinato.When I run ostinato, it does not start drone (the server) automatically The fix is simple - just add C:\windows\system32\Npcap\ to your system PATH. If you have npcap installed in native mode, the DLLs are installed into C:\windows\system32\Npcap\ instead of the standard system DLL directory C:\windows\system32\ If you do, check the location of wpcap.dll and packet.dll. Ostinato on Windows does not start because wpcap.dll or packet.dll is not foundįirst make sure you have npcap (or winpcap) installed. Where do I get answers regarding the Ostinato Python API? How do I see debug console logs on Windows platforms? Why isn’t my PCAP file imported correctly? Ostinato shows a “diff” after import Can I save/restore streams across Ostinato sessions? ![]() ![]() When I try to view the capture buffer, Wireshark gives me an error “The file could not be opened: Uncompression error: buffer error”. Why does my DUT show incoming traffic rate less than the outgoing rate shown by Ostinato? What is the maximum transmit rate that Ostinato supports? On starting Ostinato/Drone, I get an error “bound address is already in use”. ![]() Ostinato on Windows does not start because wpcap.dll or packet.dll is not found
