Initialization Problems.

[kimichen13]

I am really interested in your idea of lobbyboy. But I know nothing about python.

So here is my problems during initialization, can you help me to figure it out?

1. I configure my own data_dir but service start with an error.
   obbyboy.utils: Error when reading available_servers.json, [Errno 2] No such file or directory: '~/Software/lobbyboy/data/available_servers.json'
   Even I create the available_servers.json file, it does not work. Until I write {} to the file.
   But I'm not sure if this is ok for the lobbyboy service
2. When I ssh with ssh Kimi@127.0.0.1 -p 12200, the logs shows an error below:

ERR [20211119-17:40:41.664] thr=123145413386240 paramiko.transport: Unknown exception: too many values to unpack (expected 2)

ERR [20211119-17:40:41.667] thr=123145413386240 paramiko.transport: ValueError: too many values to unpack (expected 2)

I did some research but it's really difficult for me to understand python.

So if you can give me a hand, that's would be nice.

Thank you.

hi @kimichen13 thanks for reporting this issue.

for 1: it is ok to see this error, because lobbyboy will start to clean up the spare servers (start a thread called server-killer) once it started. Because you don't have any servers yet so the db file is not exist. it is ok for this error. however, I have changed to log level into warning.

for 2: I think there might be extra space in your rsa key config: https://github.com/laixintao/lobbyboy/blob/1df9317202104872e69e2688816eea420fbb1130/lobbyboy/conf/lobbyboy_config.toml#L18
so the split failed.

but it is also a bug, we should only split the key once, but the current code is split twice. As its format should be sth like ssh-rsa AAAAB3Nz..., (only 1 space)

fixed here: 1df9317#diff-0ac1b5794560c86cf87d34d7bc30b18b0875d637c7dc9b1c596e6517d90b3a14L103

those patches were released to 0.2.4, cloud you please upgrade then try again?

This project might lack some tests, if you found anything abnormal, inconvenience, or if you have any issues, feedbacks, advice, feel free to file an issue here :)

Thanks for your reply.

After upgraded, I get lobbyboy-0.3.0.

1. Run lobbyboy-server -c config.toml, it gets an error:

Traceback (most recent call last):
  File "/usr/local/bin/lobbyboy-server", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.9/site-packages/lobbyboy/main.py", line 101, in main
    config: LBConfig = load_config(Path(args.config_path))

    return should_be(**value)
TypeError: __init__() got an unexpected keyword argument 'loadmodule'

2. I try to regenerate the configuration file with command lobbyboy-config-example > config.toml, but still get error below:

Traceback (most recent call last):
  File "/usr/local/bin/lobbyboy-config-example", line 8, in <module>
    sys.exit(print_example_config())
  File "/usr/local/lib/python3.9/site-packages/lobbyboy/scripts.py", line 6, in print_example_config
    with open(example_config_file, "r") as conf:
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.9/site-packages/lobbyboy/conf/lobbyboy_config.tom/conf/lobbyboy_config.tomll'

I just found that the last line of the error maybe a typo. The template file in your project is lobbyboy_config.toml, not lobbyboy_config.tomll.

However, I still cannot figure out the reason of the first error. Could you help me to solve it?

Thank you.

hi @kimichen13 thank you for your patience.
for 1, it's correct to configuration config, we've change some configuartions to make it easier to read for human.
for 2, this is indeed a typo error, we'll fix it.

thank you very much for your feedback.

[kimichen13]

Thanks. I manually replace the configuration file, it works.
