Failed to Run Judge

[joonas-yoon]

i'm working on Ubuntu-16.04-LTS (64bit) i tried to run a judge (is it instance?), and followed guide on docs. but i can not find details about this on docs.

First, run server with python manage.py runserver 0.0.0.0:5000 in site/. and then dmoj localhost -p 5000 -c judge/config.yml

i got error messages under.

(dmojsite) joonas@joonas-ubuntu:~$ dmoj localhost -p 5000 -c judge/config.yml

what do I have done wrong? please help.

Check BRIDGED_JUDGE_ADDRESS in local_settings.py. There is a port where judge can actually access.. I guess. And Check if python manage.py runbridged is runned by supervisor.

ps. I think we have same goal. I hope we help each other.

[joonas-yoon]

thx for your reply. but it still isn't working. I used a port 5000 for server(site), and 5001 for bridged judge.

And more, server logged following messages when I tried to run a judge.

I changed encoding utf8 from ascii but it has problem too. I think it has a problem with zlib_~~ on packet.py or something else.

How can I check if python manage.py runbridged is runned by supervisor?

I just typed a command $ python manage.py runbridged on prompt, but nothing happend. 😢 After type that command, prompt keep waiting (or running) with nothing.

The bridge is supposed to always run alongside the site, so runbridged should be executed in the background. Otherwise, judges can't connect to it.

[joonas-yoon]

excute in background, but still not working with same error messages. I guess that is not problem by runbridged

It helps if you connect the judge to the bridge IP and port... Instead of trying to edit the code when you don't even know what it does...
