Titel: Pro FTPD starke Verbindungsprobleme Beitrag von: ReneAlsGast am 28. November 2005, 23:42:18 Seit einiger Zeit, kämpfe ich mit dem Problem, dass ProFTPD vom Server meistens schlecht erreichbar ist, dies läuft so ab:
Pro FTPD meldet sich FTP Client von mir sendet Username Paßwort Und nun wird die Verbindung zurück gesetzt(das Problem besteht aber nicht nur an meinem PC und nicht nur in meinem Netzwerk) Paßwort ist übrigens nicht falsch Wenn ich z.B. in WS FTP LE einstelle, es soll bis zu 20mal versuchen zu connecten, kanns sein, dass beim 14. Connectversuch alles normal geht. Serverlogs sagen dazu nichts besonderes- ein normaler Verbindungsversuch einfach Hier mal ein Logauszug mit 3 fehlerhaften Versuchen(wobei es eigentlich mehr waren) Zitat alster079 [18752] 213.163.236.36 [28/Nov/2005:21:06:33 +0100] "USER payne" 331 alster079 [18753] xxxxxxx [28/Nov/2005:21:06:34 +0100] "USER payne" 331 alster079 [18754] xxxxxxxx [28/Nov/2005:21:06:35 +0100] "USER payne" 331 alster079 [18754] xxxxxxxx [28/Nov/2005:21:06:35 +0100] "PASS (hidden)" 230 Beim letzten Versuch mit dem Code 230 klappte es. Und achja, die detaillierteren Logs sagen auch nichts wichtiges.

Habe Debian Sarge, ProFTPD als Debian Paket Die aktuelle Stableversion.. Titel: Re: Pro FTPD starke Verbindungsprobleme Beitrag von: stonki am 29. November 2005, 10:57:56 Debug Log. Sonst wird das nichts.
