I deploy a ftp server using VSFTPD, and trying to connect with it.
Then something weird appears, I can only see directories but no file.
I tried it using all kinds of my different physical machine and ftp client app, but it doesn't work.
For example, it is what I seen in ftp client:
ftp> ls
227 Entering Passive Mode (***,**,***,**,34,193).
150 Here comes the directory listing.

and it's what really in this folder:

Notice that LICENSE is in mod rwxrwxrwx, but it can't be seen either.
However, if I use SFTP instead of FTP, it will be fine.
Is it anything wrong with VSFTP? I didn't change any config of it, except of user list(allowing root user) and pasv port(8888-8899).
Firewall: disabled; CentOS: CentOS Linux release 7.9.2009 (Core); VSFTPD: vsFTPd 3.0.2
Oh! I found what's wrong.
I'm using SELinux, so it block some of ftp access.
I just need to shut it down.
