hallo,
ich habe schon Jahre mit folgendem Problem zu kämpfen. Da ich meinen vserver (debian 9) Letzens komplett neu aufgesetzt und das Problem immer noch besteht, mache ich jetzt diesen Thread auf.
Ich habe auf dem Server eig. nur Froxlor laufen für mehrere Webseiten und Datenbanken. für FTP nutze ich propftd. eingerichtet habe ich den proftpd Server quasi per copy & paste über die Konfiguration in Froxlor, da stehen alle Befehle drin die man auszuführen hat. Hier der Inhalt:
apt-get install proftpd-basic proftpd-mod-mysql
/bin/nano /etc/proftpd/create-cert.sh
chmod 0700 "/etc/proftpd/create-cert.sh"
chown root:0 "/etc/proftpd/create-cert.sh"
/etc/proftpd/create-cert.sh
rm -f /etc/proftpd/create-cert.sh
mv "/etc/proftpd/proftpd.conf" "/etc/proftpd/proftpd.conf.frx.bak"
/bin/nano /etc/proftpd/proftpd.conf
chmod 0600 "/etc/proftpd/proftpd.conf"
chown root:0 "/etc/proftpd/proftpd.conf"
mv "/etc/proftpd/modules.conf" "/etc/proftpd/modules.conf.frx.bak"
/bin/nano /etc/proftpd/modules.conf
chmod 0644 "/etc/proftpd/modules.conf"
chown root:0 "/etc/proftpd/modules.conf"
mv "/etc/proftpd/sql.conf" "/etc/proftpd/sql.conf.frx.bak"
/bin/nano /etc/proftpd/sql.conf
chmod 0600 "/etc/proftpd/sql.conf"
chown root:0 "/etc/proftpd/sql.conf"
mv "/etc/proftpd/tls.conf" "/etc/proftpd/tls.conf.frx.bak"
/bin/nano /etc/proftpd/tls.conf
chmod 0644 "/etc/proftpd/tls.conf"
chown root:root "/etc/proftpd/tls.conf"
Problem ist, dass wenn ich größere Dateien kopiere die Verbindung einfach abbricht vom Server. es kommt mir so vor wie wenn er die Verbindung immer nach X Megabyte verliert. wenn ich ab und zu kleine Dateien ändere (im editor geöffnet, Änderungen speichern und direkt hochladen) ist die Verbindung lange am laufen, verbinde ich mich frisch und kopiere direkt Ordner mit vielen großen Dateien lokal auf den PC, wie beispielsweise das phpMailer-Paket, dauert es keine 10 Sek. bis er mitten beim Kopieren die Verbindung verliert.
Was kann das sein ? Wie kann ich das troubleshooten?
im proFTPD log steht nicht dazu:
Danke!
