How to run the server

First compile

make

then start the server

./RunServer start

to show the server's console

./RunServer show

to start the server in secure mode (both HTTPS and WSS)

./RunServer start --https

Before you can use WSS with a self-signed certificate, you need to browse to https://localhost:4444 and add it to the certificate exceptions of your browser.

Now you can navigate to localhost:8000 (https://localhost:4443 if https)

and submit a job as professor

File downloads

The flask server allows to use special tokens for file downloads.

Example: to create the token for file alabno/tmp/test.txt run script alabno/frontend/CreateDownloadToken with argument alabno/tmp/test.txt CreateDownloadToken will print to stdout the token that can be used to retrieve the file.

It's also possible to write the token to file with

./CreateDownloadToken alabno/tmp/test.txt --out /tmp/token.txt

To give users access to the file, use the link

http://localhost:8000/result/token

or

http://tc.jstudios.ovh:8000/result/token

replacing token with the token, and replacing https and ports with the correct combination.

A token will be valid only for a limited amount of time. By default this is 20 minutes.

User accounts and authentication

Imperial College LDAP authentication can be used to log in. This is enabled only when the server is started with --https.

If no --https is used, the client will not send any password back, and the server will only simulate user accounts. Logging in with any username that starts with A will authenticate an Admin, any username that starts with P a Professor, anything else becomes a Student.
