impossible to connect to FTP
Posted: 2020/06/17 03:19:32
I have tried unsuccessfully the connection via passive FTP to a VPS because when listing the directories the session is disconnected.
I am using firewalld in public area and I have allowed access to the ftp service with the command:
firewall-cmd --permanent --zone=public --add-service=ftp
firewall-cmd –reload
I have told me that I put in listening port 20 I have tried as much as port service without results
I would appreciate if you could give me an idea of what might be happening because I have verified that the ftp service is listening from the internet, so I rule out the firewall problem

I would appreciate if you could give me an idea of what might be happening because I have verified that the ftp service is listening from the internet, so I rule out the firewall problem
