Question

我使用bash脚本（https://github.com/johnnywoof/FTP-Bash-Backup）将我的Debian www目录备份到ftp服务器。一切顺利，但转移阻止防火墙。该脚本每次都使用单独的端口，因此我无法通过防火墙取消阻止。有没有办法指定端口？

Bash脚本

# FTP server settings
USERNAME=""
PASSWORD=""

backup_remote_file_name="$timestamp.tar.gz"
backup_file="$TEMP_BACKUP_STORE/$backup_remote_file_name"

echo "Removing files older than $MM $DD"

lista=( $listing )

    #echo Date ${lista[`expr $FNO+5`]} ${lista[`expr $FNO+6`]}          File: ${lista[`expr $FNO+8`]}

    if [ ${lista[`expr $FNO+5`]}=$MM ];
    then
        if [[ ${lista[`expr $FNO+6`]} -lt $DD ]];
        then

echo "Deleting temporary files..."
rm $backup_file
echo "Backup complete."

切换到被动模式：

在passive命令后将user插入新行。
