FTP: 451 aborted, can't open file

Post by trisonic »

I have some issue with my remote ftp.

It works perfeclty with FileZilla but I can't connect with syncback pro.

I don't know if i'm missing something but this is weird:

This is the output log from FileZilla.

It seems that the ftp server (it's an instrument) use LIST instead of MLIST.
But it still not working if I change the options to use LIST instead of MLIST.

I can't understand why the ftp client of syncback pro do this command:
STOR XXXX.file

with random file...

Code: Select all

Re: FTP: 451 aborted, can't open file

ok, i got the problem:

i don't have permission on the root directory /
but i have alle permissions in one of the subdirectory: /CRD
in that subdirectory there is all the data data i need to backup/manage.

how can i set the "working directory" to /CRD instead of root directory?

syncaback can't perform the ftp test on the root directory because I don't have permissions...

I have changed the working directory by inserting manually in the source tab.

Now it "works" but........... i have issue with the LIST command.
I can't see anything with syncaback... i have disable MLST and used alternative file parser but... nothing.

The ftp server is a datalogger with a ftp built in: https://www.campbellsci.com/cr3000

The strange thing is that with FileZilla i can browse and create/delete file in the ftp directory.
But I have issue with syncback.

What can i do to allow syncback to work properly with this ftp server?
