@tommaso.piccioli@isti.cnr.it @leonardo.candela@isti.cnr.it did you use ftp over TLS? The IIT people say that ftp over TLS is already enabled, while plain FTP is blocked,
Updated by Tommaso Piccioli over 2 years ago
You are right, it is working using ftp explicit over TLS.

I didn't manage to connect neither by using ftpes:// nor ftps:// (I'm using Filezilla)
In particular when using ftps:// I see

I just replicated the behaviour, trying from home. I'll ask the IIT people again.

I reopen the ticket because ISPC colleagues have been reported frequent disconnections using FileZilla
I have obtained the same problem using my PC connected to the ISTI network, after few minutes of usage:
Stato: Avvio download di /documents/2019/413302/info.txt Stato: Trasferimento file completato; trasferiti 276 byte in 1 secondo Stato: Disconnesso dal server Errore: Errore GnuTLS -15 in gnutls_record_recv: An unexpected TLS packet was received. Errore: Impossibile leggere dal socket: ECONNABORTED - Connessione interrotta Errore: Disconnesso dal server

I do not understand. If there were no file transfer in action, the disconnection is the expected behaviour.

It looks like an error caused by the filezilla client settings, it can use multiple simultaneous connections and there is an automatic timeout client-side, probably not acknowledge by the server, then the error, maybe due to some directory listing refresh. Next new connection from filezilla, trigged by a click on a directory or a upload/download request, will be succesfull if the password was saved.
It is possible to change timeout, number and frequency of retries and add a timestamp to the log.

@michele.artini@isti.cnr.it 5 minutes is the default timeout server-side for the idle connections, can we close this?

Mando una email per capire quale sia il problema ... รจ evidente che questo della disconnessione non lo sia ma lui ha parlato di problemi durante il download o l'upload.
