Hallo,
ich benutze proftpd in Verbindung mit MySQL.
Wenn sich die User einloggen und etwas hoch oder runterladen kommen nach wenigen Sekunden Fehlermeldungen wie diese:
"421 No Transfer Timeout (600 seconds): closing control connection."
oder
"maximum connections per site reached"
je nach client.
Woran kann das liegen?
Meine Konfigurations-Datei von proftpd:
# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use. It establishes a single server
# and a single anonymous login. It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.
