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
( 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 )
