ich habe FTP über TLS eingerichtet, jedoch können sich nach längerer Zeit meine User nicht einloggen wegen einer Zeitüberschreitung der Verbindung. Selbst bei mir taucht das Problem auf, obwohl ich bis jetzt nach einem Reconnect immer reinkomme. Sind meine User jetzt einfach nur zu doof, oder hab ich in der Config was verwurstelt.
Hardware: AMD 5600+ Dual core,mit 2Gbyte Ram und 100Mbit Standleitung.
OS: Debian 4.0, kein xinetd, standalone server(xampp1.6.4)
