Generally: No. Only in very limited cases, when the applications provides a state table sync. This is the case i.e. for iptables firewalls and ipvs load balancers. In some cases the tcp stack can recover the connection and some times the applications can recover (FTP, downloads in HTTP, ...) or just retry. But in most cases the users will have to press "reload" or something comparable. -- Mit freundlichen Grüßen, Michael Schwartzkopff -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64, +49 (162) 165 0044 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
