Share a local folder on LAN without Sambashare?

Sharing a folder on Windows is a trivial matter. Sharing a folder on linux appears to be done only using Sambashare. At least, every guide I've found is using this approach. It's quite terrible, requiring config files, user groups, additional packages etc. Is there a way to share a local folder without this program? Right now, it seems to be easier to upload things to the cloud to transfer files between two linux computers on a LAN.
