Per one of the threads in this forum, I modified /etc/e-smith/templates/etc/proftpd.conf/template-begin to change a couple parameters. Before I did, I made a backup copy of the template file.
I changed the ServerName string, MaxClients from 10 to 5 for Anonymous access.
Then I saved it, and signalled a console-save event. I reboot, and FTP would not work.
So I copied back the original template file, console-saved... reboot... and STILL, "connection closed by remote host" by both the outside and inside IP addresses.
How can this be?
