Created attachment 116236 [details] The no transfer timeout error while trying to send keepalive. Hello, I would suggest to ignore ftp no transfer timeout error: "FTP 421 No Transfer Timeout (300 seconds)". This is an error that occurs whenever you try to keep alive an ftp connection without transferring any data. It's a bit annoying to receive this error and I think there is no reason to report it to the user with an alert message window. I would suggest to just write it on the output log and close the connection.

Will try to have a look at it. Thanks for reporting.
Hi, Probably another solution could be closing ftp connection after a timeout if the keep alive option is not set, so that we can close the connection without errors before the remote server does. Bye, Gianni
Very similar to issue #203987 but apparently its fix does not work for all servers :) Now, after every 10th NOOP command PWD command is send. Do you think whether there is a better command to be send to the server (instead of the PWD command)? If not, I will do what you suggest - just disconnect and add a message to the log. Thanks for reporting.
Fixed. Feel free to verify and reopen if you have a better idea (e.g. what command should be send to the server to avoid this error). Thanks. http://hg.netbeans.org/web-main/rev/a4a6221987a2
