Carla: Help Requested : Server port is closed and Errno 111

Created on 25 Apr 2018  路  10Comments  路  Source: carla-simulator/carla

Hi,
I am trying to test client_example.py on my server. However, I received below messages only although I turned on the server using ~/UnrealEngine_4.18/Engine/Binaries/Linux/UE4Editor "$PWD/CarlaUE4.uproject" -carla-server command.

Error : ERROR: (localhost:2000) failed to connect: [Errno 111] Connection refused

At first, I thought that it was firewall problem but, I found that though I turned on the server, the port is not activated according to netstat -ano and nmap localhost -p 2000.

Could you help me solve this problem?

My server setting is like this

Meet same problem. Hope someone can help solve it. Great thanks.

I just checked the code for carla, find the error is raised in Pythonclient/carla/tcp.py, line 44:

except socket.error as exception: 45 error = exception 46 logging.debug('%sconnection attempt %d: %s', self._logprefix, attempt, error) 47 time.sleep(1)
For me, this socket.error is caused by fact that carla server is not listening at port 2000,
you could check whether server is listening or not by type

lsof -i:2000 in terminal, if your port is 2000.

I use word-port 2000 to start the server, then the problem is solved.

Hope it's useful for you.

@jackspp Thanks for sharing your experience. I think I also checked using nmap and netstat. It is still closed although I set port 2000 or other.

Does it work when you run the compiled version?

And just to make sure, have you pressed "Play" after opening the editor? It doesn't seem so in the log.

@nsubiron I am running on server. So I do not have play button. I succeeded one server using compiled version. However, I still fail to use source code version. In addition the other server does not work both compiled and soource code

jd730 picture jd730 on 30 Apr 2018

@jd730 The source code version by default launches the editor, not the game, you can compile a packaged version on a headless server using

$ export UE4_ROOT=/Path/to/UnrealEngine
$ ./Rebuild.sh --no-editor
$ ./Package.sh

@nsubiron Thank you for giving information.
Currently, I confronted CMake Error. I will resolve it later.

By the way, one server had same problem on issues(port does not open) although I used compiled version.

cf. CMake error is below.

CMake Error: The current CMakeCache.txt directory /home/jdhwang/t_carla/Util/Build/googletest-source/build/CMakeCache.txt is different than the directory /ho                                                                                me/jdhwang/carla/Util/Build/googletest-source/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you ar                                                                                e not sure, reedit the CMakeCache.txt
CMake Error: The source "/home/jdhwang/t_carla/Util/Build/googletest-source/CMakeLists.txt" does not match the source "/home/jdhwang/carla/Util/Build/googlet                                                                                est-source/CMakeLists.txt" used to generate cache.  Re-run cmake with a different source directory.

@jd730 If the port does not open in just one machine, it's probably an issue with the configuration of the machine, make sure too that no other application in that machine is using the same port.

About the CMake error, I see I made a mistake in the instructions I gave you above, should be _Rebuild.sh_ instead of _Setup.sh_ (already fixed it), sorry about that :confused:. The easy but long way to fix it is to remove the folder _Util/Build_ and run the setup again, full instructions

$ rm -Rf Util/Build
$ ./Setup.sh
$ export UE4_ROOT=/Path/to/UnrealEngine
$ ./Rebuild.sh --no-editor
$ ./Package.sh

Like you said, re-install worked although I used script of compiled version.
Thanks.

adding "-port=2000" helped
Thanks
