Dateien werden vollständig gesendet, aber nicht vollständig auf dem FTP-Server (Proftpd) empfangen.

Ich habe versucht, Proftpd zu verwenden, um einen FTP-Server auf einem alten Laptop einzurichten, den ich habe. Nach dem erfolgreichen Einrichten des Servers und der Benutzer ist mir jedoch aufgefallen, dass ich die Datei immer von einem anderen Computer in voller Größe auf den Server hochladen kann, es sei denn, die Datei ist klein genug (etwa 50 KB). Die tatsächliche Datei, die auf dem Server empfangen wird, ist jedoch immer einige Kbs kleiner als die ursprüngliche Dateigröße. Dies ist das erste Mal, dass ich einen Server einrichte, und ich habe keinerlei Erfahrung mit FTP-Servern oder Servern im Allgemeinen. Ich habe versucht, die Konfigurationsdatei so gut wie möglich einzurichten, aber aufgrund meiner Situation habe ich wahrscheinlich hier oder dort etwas vermisst. Hier sind die Inhalte der Datei proftpd.conf.
