When I try to do a simple syn flood attack on localhost, just to get an idea of how hping works, I keep getting this error:
[main] no such device
I don't quite understand what it means or how to fix it. Any help?
Again, I'm using the native win32 hping2.

Please suggest to resolve this problem. I checked and found that .netCore upper version not support to old version code.

I'm running Appium 24/7 on a Windows machine to perform automated tests. I'm running these tests via AVD on an emulator with Android 10. For my test, I give the correct Capabilities and runs functionally great. But after a few hours/days I get the follow error:
UnknownError: An unknown server-side error occurred while processing the command. Original error:*Cannot find any free port in range 8200..8299}. Please set the available port number by providing the systemPort capability or double check the processes that are locking ports within this range and terminate these which are not needed anymore at getResponseForW3CError at asyncHandler.
When my code is executed, I make sure the finally in try executes the AppiumDriverLocalService.stop(); method to kill Appium. My feeling says this does somehow not free up any ports for UIAutomator2 (which you can configure, but I have not configured, through systemPort capability.
} finally {
driver.closeApp();
service.stopServer();
System.exit(0);
}
Why does Appium not free up any ports for UIAutomator2 in the range 8000-8299 after stopping the service?
Android Debug Bridge version 1.0.40
Appium version 1.20.2
Android 10
PS I know of the adb command adb -s $UDID forward --remove-all but does this solve the real issue, I don't want to execute a Java Process each time
Update - Fix 2-3
I have fixed the issue by changing the finally clause to execute the following methods in order:
} finally {
AndroidDriver.quit();
AppiumDriverLocalService.stopServer();
In order to free up the port 8200..8299, AndroidDriver must be quit as UIAutomator2 is linked to this. The AppiumDriverLocalService will kill/forward/free this port and UIAutomator2, after this I can freely stop the server:
[ADB] Removing forwarded port socket connection: 8203
This issue is a good example of your problem. As you can see, Appium team is closing it as a Not A Bug.
Reason is obvious: Appium is not responsible for managing ports, it relies that your system has some free in required (by Appium code) range.
systemPort is used to connect to appium-uiautomator2-server, by default is 8200. Basically Appium selects one port from 8200 to 8299 for appium-uiautomator2-server. However, when you run tests in parallel, you must adjust the port to avoid conflicts. If you are not, you should be safe in 99% cases with the default.
Restart the system (assuming it will clear ports) and run tests. Check Appium server logs for any errors on closing session. It could be that issue is related to ADB setup or permission issue, and UI2 server is not stopped properly.
If so, port remains in use. And it is not Appium to deal with cleanup. I'm not sure that adb command you mentioned is a good 100% guaranteed way to do it.
I would just add a shell script that is executed before Appium server start to clean ports in 8200-8299 range and forget this problem.
killall -9 node - to kill all appium running internally and at root level
and adb kill-server - to kill the abd server by running this it resolved the above issue for me , hope may help someone
I'm trying to use the Thingsboard gateway to connect to a PFC200 PLC, which is running Codesys. I can't get the Gateway OPC-UA extension to connect.
The name 'pfc200' resolves OK in a terminal (ping pfc200) and port 4840 is open, but when I start the gateway, the gateway crashes with the Java exceptions listed in the log file. (snippet below)
I'm using the debian distribution from gitub; version 1.2.1 on a 64 bit Mint VM running under virtualbox. The name 'pfc200' is listed in /etc/hosts. I added a DNS name in my server, which also failed. Note: I still haven't figured out the proper Application URI. But .. I'll open another topic for that issue.
Thanks for any help.
Snippet from /var/log/tb-gateway/tb-gateway.log:
2017-11-04 10:27:39,602 [main] INFO o.t.g.e.opc.OpcUaServerMonitor - Initializing OPC-UA server connection to [pfc200:4840]!
2017-11-04 10:27:43,125 [main] ERROR o.t.g.e.opc.OpcUaServerMonitor - OPC-UA server connection failed!
java.util.concurrent.ExecutionException: java.nio.channels.UnresolvedAddressException
at java.util.concurrent.CompletableFuture.reportGet(CompletableFuture.java:357)
I used the free UAExpert tools to test the URI. After successfully testing my connection there to a Raspberry Pi running Codesys as an OPC Server I then used that URI in my JSON file for the gateway. You can get this from the properties of the connection in this software. This information should get you past that part:
You can also try typing in the IP address in the URI like this:
2018-02-13 17:54:44,267 [main] INFO o.t.g.e.opc.OpcUaServerMonitor - Initializing OPC-UA server connection to [192.168.1.29:4840]!
I'm using the simulator (iOS 9.0).
I’m running the command: device_target=UDID cucumber
The simulator starts and the app is loading, but then the console hang for few min until time out.
I have the same issue when I run it manually in the console:
calabash-ios console
start_test_server_in_background
The error that I get is:
#<RuntimeError: Timed out connecting to Calabash server after 10 retries. Make sure it is linked and App isn't crashing>
RuntimeError: Unable to make connection to Calabash Server at http://localhost:37265/`
Make sure you don't have a firewall blocking traffic to http://localhost:37265/.
running the command curl http://localhost:37265 and get the error - curl: (7) Failed to connect to localhost port 37265: Connection refused
what I’m missing?
(the app developed in Xamarin)
device_target=UDID cucumber
This is not doing what you expect. Calabash responds to DEVICE_TARGET not device_target.
My best guess is that you need to check whether your .app is linked with Calabash.
Please see these two pages:

When I start Phusion Passenger Standalone web server (version 5.0.2), I see the following error in the log (even though everything works fine otherwise):
ServerKit/Server.h:892 ]: [Client 1-1] Disconnecting client with error: client socket write error: Broken pipe (errno=32)
Any idea what might be causing it?
Note: I start the server with foreman start and I stop it with control-c.
Passenger author here. Actually, the issue maxd linked to has got nothing to do with it.
The "Disconnecting client with error: client socket write error: Broken pipe" is a harmless informational message. It's quite normal, but I forgot to give it a lower logging level. I will do that in the next release. You can safely ignore this message. Nothing bad is going on.
