The db file contains a script to set up the database, so use it with your favorite RDBMS. If you’re content with defaults (SQLite), then simply run this:

sqlite3 ket.db < db

There are two ways the script can authenticate to the website: cookie and password. If you don’t want to leave the password in your shell history, then using the cookie is preferable. All you need to do is log in with your browser and extract the value of the CMSSESSID520b200f cookie and pass it to the script via the --cookie option:

scrape.py --category=B --cookie=<COOKIE>

If you don’t care:

scrape.py --category=B --password=<PASSWORD>
