– When trying to FTP, do you face 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(x)
-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‘ ( pure-ftp ) or ‘MaxClientsPerHost‘ ( pro-ftpd ) and restart the service.
Alternatively, you can also terminate the existing connections from the IP, if they are not in use.
# netstat -plan | grep :21 | grep 'IP'
# kill -9 PID ( <- kill the corresponding process )
