I currently purchased Synology's ds220+ model and am using it as a NAS Server.
The line is connected to the LAN port of the router to which the WAN line is plugged, and the end is connected to the NAS.
In this situation, I wanted to set up a NAS server to be used externally, not on a local network.
So I even set up WebDAV Server, DDNS, and port forwarding on the router.
To test this, I created a NAS server directory through RaiDrive in a Windows environment.
From the created directory, I tried to upload files to a folder with read/write permission and confirmed that it was working normally.
However, the problem occurred in MacOS.
In Finder, a server folder was created through the "Connect to Server" option, and a file upload was attempted, but an error such as the attached picture occurred in all types of files.
Could you tell me if there is a problem with the way MAC creates the server folder?
Idea: Your OS doesn't support SMB:
Download an FTP or SMB client. (FTP: E.g.: Filezilla)
Idea: A friewall is blocking it:
Check your anti-virus-program
Other Problem:
Use an USB Stick & NAS USB Copy
or upload it via DSM File Manager
Open NAS IP-adress via Safari/Firefox/Chrome
Log In
Open File Station / File Manager
Search folder
Click [Upload]
Choose the file from your PC

I have a NiFi instance running on my local Windows workstation.
I want to copy a flow file to a shared network drive: \\sharedpath\files\destination
I am able to use the PutFile processor to copy the file to C:\Temp\Files for example on my C drive.
But PutFile doesn't work with Windows shared network path such as \\sharedpath\files\destination.

I'm getting started with imx6 processors and the procedure involved to bring up the board is to flash u-boot kernel dtb and rootfs which is taken care of by mfg tools provided by nxp.
For creating a rootfs partition the command run is
mkfs.ext3 -F -E nodiscard /dev/mmcblk1p2
and for untaring the rootfs into this partition it is.
pipe tar -jxv -C /mnt/mmcblk1p2
I'd like to know the working of this, which kernel driver is being called for executing these commands?
My kernel version is 4.9.88.
I did find a few driver files related to mmc in the path
/drivers/mmc/core
but there is nothing related to filesystem reading or writing here.
Can anyone explain which driver files are used to create filesystems?
Creating the filesystem is done by the userspace program mke2fs (of which mkfs.ext3 is an alias) which is part of the e2fsprogs package. The kernel and drivers have no way of creating filesystems. Therefore, only the block driver for accessing the MMC device is involved, but no file system driver.
I have a device that saves screenshots when you put a flash drive with exFAT/FAT32 and a specific directory tree in its USB socket. I want to livestream these screenshots to other devices as fast as possible via ethernet:
device -> flash drive -> ethernet
So I tried an ARM device (Orange Pi Zero) with OTG support and g_mass_storage kernel module which emulates an USB flash drive via USB OTG:
g_mass_storage - To have your Pi Zero appear as a mass storage device
(flash drive), first create a mini filesystem in a file on your Pi
with sudo dd if=/dev/zero of=/piusb.bin bs=512 count=2880 and set it
up as a fat32 filesystem with sudo mkdosfs /piusb.bin. Then, when
enabling it, add file=/piusb.bin stall=0 onto the end, for example
sudo modprobe g_mass_storage file=/piusb.bin stall=0.
(from https://gist.github.com/gbaman/50b6cca61dd1c3f88f41)
Next I mounted the emulated flash drive for testing purpose on a Laptop (Linux Mint 18) and the flash drive file via sudo mount /piusb.bin /mnt/ on the ARM device. But when I add new files/directories in one system it doesn't appear on the other. I have to remount the device/file first to refresh the files.
So is it even possible to read (and stream) the written data at the same time on my ARM device with g_mass_storage? Or is there a better way to solve my problem?
You should try to remount it.
sudo umount /mnt/
sudo mount /piusb.bin /mnt/
I have a remote embedded system which it is telnet-able. How can I download a binary file from the host to it? I can read file from the system, but have no idea how to write to it.
you probably want to do this with ftp
If there is no ftp server on the target system try using kermit
