    AW: ProFTPd Threads (multithreading) ???

    Wie meinst du denn das? Das ProFTPd kann doch von Haus aus mehrere Verbindungen aufbauen, außer es gibt ein IP Login Limit. Ansonsten hängt das eher von deinem Client ab.

    Bevor man an Serverdiensten wie ProFTPD etc. heranwagt,
    sollte man ein solides Grundwissen von Linux haben.

    Welches du sicherlich nicht hast.
    Falls doch, Pardon.

    Vielleicht hilft dir das:
    Spoiler
    MaxInstances: Beschränkt die Gesamtzahl der Verbindungen

    MaxClients: Beschränkt die Anzahl der Verbindungen pro Server/virtuellen Host

    MaxClientsPerHost: Beschränkt die Anzahl der Clients die sich von einem Host anmelden können

    MaxClientsPerUser: Beschränkt die Anzahl der Verbindungen die gleichzeitig unter dem gleichen Usernamen aufgebaut werden können

    MaxHostsPerUser: Beschränkt die Anzahl der Rechner, von denen sich jemand mit dem gleichen Usernamen einloggen kann

    Und Google´n ist nicht schwer
