#12615 closed Feature request (rejected)

Feature Request: provide a milllisecond delay parameter to session termination after 'Goodbye.'

Reported by: Steve Fox Owned by:
Priority: normal Component: FileZilla Server
Keywords: goodbye. Session destroyed Cc: Steve Fox
Component version: 1.1.0 Operating system type:
Operating system version: Server 2012r2

Description

We have a contact using a 'slow' system that sends us small EDI files and after our upgrade to 1.1.0 started to received errors at the end of the session.

We suspect that during the session termination protocol Filezilla closes the socket quickly - creating a socket termination error on their side because they are still processing the 'Goodbye.' acknowledgement

Would you please consider adding a timeout value in MS (up to say, 5000 or more) in the configuration to allow for the client to process and disconnect from their side prior to the session destroy? Everything still works, but it generates a non-critical error for each session
Thanks

There is no need to send a QUIT command, you can just close the connection outright. As per specification, closing it without QUIT is equivalent to ABOR+QUIT.

Furthermore, according to the example at https://datatracker.ietf.org/doc/html/rfc959#section-7 a reply to QUIT is not needed.
