Server zu Server Dateitransfer Port?

Question

Ich verwende ein Bash-Skript (https://github.com/johnnywoof/FTP-Bash-Backup), um mein Debian-WWW-Verzeichnis auf einem FTP-Server zu sichern. alles lief gut, aber die Übertragung wurde von der Firewall blockiert. Das Skript verwendet jedes Mal einen separaten Port, damit ich nicht durch die Firewall entsperren kann. Gibt es eine Möglichkeit, einen Port anzugeben?

Der Bash-Skript

Wechseln Sie in dem passiven Modus:

Insert passive in einer neuen Zeile nach user Befehl.
