Server lahm - FTP, HTTP und Co...
Posted: 2008-12-14 20:12
Ich möchte gern den ProFTP Daemon absichern. Soweit so gut, doch in der Standardkonfiguration wird der Server bei jenden FTP-Download geblockt. Sprich er reagiert erst wieder flüssig wenn der Download/Upload fertig ist. Nach ein paar Recherchen habe ich die Config etwas angepasst. Jedoch kann ich mich jetzt nicht mehr einloggen :?
Hat jemand eine gute Config die alles abdeckt, funktioniert und den Server nicht lahm legt?
PS: Wenn jemand für DTC vsftpd zum Laufen bekommt bin ich gern für eine Lösung ansprechbar. pure-ftpd kann ich nicht gebrauchen da dort nur max. 4GB Dateigröße unterstützt wird (jedenfalls kenn ich keine Option die das ausstellt).
Bye, TDS.
