FTP Access Denied When Attempting to Transfer Files

Permission is, as usual, a double-edged sword. It happened when I tried to transfer files to a remote Linux server.

Problem

I created a directory on the remote server and attempting to transfer files via FTP client but got an access denied error. It is weird because I do login using the same account and thus as the owner of the directory.

Solution

The one that solves the problem in my case is by changing ownership of the folder recursively (-R option) and use name of the user as group name such as:

sudo chown -R <user>:<user> <directory>
