Hi All,

I recently setup a Cent OS 7 server on my local network.

I'm trying to enable FTP, but struggling.

I followed this guide and everything seemed to work.  However I can't telnet to port 21 on the server.  Port 22 works.

Any suggestions?

if you do netstat -at do you see it listening on port 21?
is iptables running?

iptables is not running

Veeam Task Manager for Hyper-V

Task Manager for Hyper-V provides critical information that allows you to monitor Hyper-V performance by displaying real-time views of CPU and memory at the individual VM-level, so you can quickly identify which VMs are using host resources.

from all other PC's on the same network it fails.

There are no firewalls on the other PC's.

Most notable is the fact I can telnet from other PC's to SSH port 22.  So more than likely it is a setting on the Cent OS server.

Did you actually start the FTP server? (Assuming the port is open in the Firewall on the Centos server)

Yes the service is running.

The server says it's listening on port 21 and I can telnet to port 21 using localhost.

Are there any filters in CentOS 7 / VSFTPd that stops network connections?
