According to Greek myth, malicious goblins called Kallikantzaros played troublesome pranks during Christmas time. What did the Greeks do to keep these lore-based creatures away?

It was said that Kallikantzaros came during Christmas time through the chimney or the front door. So to discourage these pranksters, the Greeks would leave a colander on their doorsteps to distract the Kallikantzaros and keep a fire burning all night to keep the little goblins from entering through the chimney.
