When trying to FTP-in, facing this error ? :
=================
Status: Resolving address of xxxxxxxxxxxxxxx.com
Status: Connecting to xx.xx.xx.xx:21…
Status: Connection established, waiting for welcome message…
Response: 421 Too many connections (x) from this IP
ons (x) from this IP
=================
As the logs indicate, the limit for connections from the IP you are trying
to login has reached its maximum value.
Increase this from the configuration file, the value 'MaxClientsPerIP'
( if its pure-ftp ) or 'MaxClientsPerHost' ( pro-ftpd)
and restart the service.
Alternatively, you can also terminate the existing connections, if they are not in use.
# netstat -plan | grep :21 and kill the corresponding process
( # kill -9 PID )
