FTP issues with Doorbell PoE
-
I have tried and tried to alter my text here but I cannot find wording that meets the "respectful guidelines". I totally don't know what it could possibly be that is wrong with my wording, but basically the FTP function does not seem to work. I tried to explain what I have done but the website does not permit me to do so.

@nick_26792935116 Don't include url as they are not allowed. Add spaces.
Try to install Filezilla or Cerberus ftp server on your PC. It should work. To troubleshoot capture traces through Wireshark. -
@joseph_1979 Thanks - hopefully I will be able to post this, although getting through the various filters has been problematic. I have a Doorbell PoE camera which I have set up to sync to a Synology box using FTP. The camera connects to the Synology and can write a file to it, so no apparent problems with authetication, but the file has zero bytes in it. Any ideas what might be causing this?

@nick_26792935116 I presume you have provided all the rights to the account. It seems it starts to write but is restricted. Would you be able to install wireshark and capture a trace? Use FTP and disable ssl on both cam and synology.
-
@joseph_1979 The user on the Synology box for the FTP transfers has full read/write access to the share, permission to use the FTP application, and no quota limiting it.
I can't write any more here without triggering the unsuitable content filter - why, I have absolutely no clue. -
@nick_26792935116 Try to disable ssl on Synology. You shouldn't have a trailing '/' at the end of the pathname.
Can you use Filezilla/Coreftp client and try to transfer from your PC to Synology using the cam account?
Any logs on Synology?
Did you upgrade the fw of the doorbell? -
@joseph_1979 There is no PC involved - just the doorbell camera straight to the Synology box over the internet. I get an error "450 Unkown error" when I use the Test function from the camera. Also of interest is that the camera has no problem creating date-organised folders on the FTP server (ie 2024 with 03 inside it and 06 inside that). The .txt file inside the last folder is zero bytes, though. The FTP log records the creation of the folders, and the user logging in successfully for the FTP transfer, but there is no record of the text file being written.
I have tried disabling SSL (ie switching off FTPS) but it makes no difference.
I have also tried changing the transport mode as there are suggestions this might help elsewhere on the web, but no joy. I am beginning to think that the FTP function is simply broken. It is frustrating because the folders get created OK, so this is working, but it just does not seem possible to transfer a file.
Just tried to post this and was denied because it has not been 1800 seconds since my last post - half an hour! Why are there such ridiculous constraints on using this board - it is almost unusable. Maybe that is the idea? -
@nick_26792935116 As you can see from screenshot below, cam starts with plain FTP and then asks for AUTH and ftp serve accepts it, it changes to FTPS using TLSv1.2.
Uh I cannot add screenshots.... Unbelievable.
Try to transfer file from your PC to Synology using the cam account.
Error 450........ like server cannot write in file. -
@joseph_1979 Yes, FW is at version v3.0.0.3215_2401262241
I have seen a couple of transfers be successful now, but it is totally random. It will work sometimes but then stop working with exactly the same settings. I do think there must be a bug in the FTP function which is causing the transactions to fail some of the time but not all the time.
Having to wait 30 minutes between posts is seriously doing my head in! I cannot wait any longer right now - I have other things to do so I will not be able to come straight back to you. -
@nick_26792935116 A wireshark trace will help.
Typical log on the FTP server side.

@joseph_1979 I have installed Wireshark on the Synology box but unfortunately I cannot work out how to capture the FTP traffic.
-
@nick_26792935116 There are lots of sites showing you how to capture traces on Wireshark. This site doesn't allow me to add any.

I'm writing to report an issue I'm encountering with the FTP function on your website. I've been trying to [describe your intended action using the FTP function, e.g., upload files, establish a connection], but I haven't been successful.
