I setup vsftpd according to several tutorials that I've read.
It is configured for known users only.
I am able to login using a remote client.
In the client several directories are displayed.
Selecting a directory displays that directory's directories.

What is not being displayed are the files.

The files on the server have their read and execute permissions set.
The owner is root.
The group is somegroup
A user was created that will login to the server.
The user is assigned to somegroup.

What could be keeping the remote client from seeing the files?
