Game server fails to start on Debian

[prockallsyms]

Hi! So last night I gathered the relevant files from the repository, pwn3 website, and docker to use docker-compose to setup the repository. Running the docker-compose binary doesn't fail, however there is a problem with the setup scripts that causes the game server to fail to boot, and exit with code 139:

I fixed it. I'll make a resolution pull request. Although I'm not sure if it's going to work for other OSs.

host:~/PwnAdventure3/client/PwnAdventure3_Data/PwnAdventure3/PwnAdventure3/Binaries/Linux$

did you execute the server on your host system?

I guess your permissions are now all screwed up, but at least it's working :D But if you want you could purge the whole docker stuff again and start fresh.

If the issue reappears you could do this troubleshooting: docker exec -i -t pwnadventure3_game_1 /bin/bash to get a bash shell inside the container, then do:

cd /opt/pwn3/client/PwnAdventure3_Data/PwnAdventure3/PwnAdventure3/Binaries/Linux/
su pwn3
./PwnAdventure3Server

Does this also crash with a segfault? If it crashes can you install strace inside this container and then start the server (as pwn3) with strace ./PwnAdventure3Server

[bennieboj]

Whatever happens inside your docker container should just work.

You should not execute the client you placed next to the docker-compose.yml on your debian host system since this one is used while running the live game server. It's better to make a copy instead. Could this be the reason for the permissions issues?

I suggest you download it all again and start from scratch. Could you please provide the logs of the docker-compose up command?

[prockallsyms]

Yeah. My host machine is down because of a partitioning error I made, but once I figure out how to fix it I'll post the logs.

[videlanicolas]

This happens because pwn3 has no write access to /opt/pwn3/server/creds, there is a step in the master server shell script where it writes the creds in that file. Sending a pull request to fix this.

Got a shell in the docker container and ran it with strace, the tail end yielded the following:
