Can't LIST -A but can write
Posted: 2022-05-23 22:45
Hi guys,
I have a php script which does a site backup. It doesnt support sftp only ftp.
What it does is, connects to the ftp, creates a file called "is_it_writable" which succeeds as I can see the file get created in its virtual root, but then it does a "LIST" and "CWD" looking for that file and filezilla responds with a 550. The script fails saying it doesn't have write access to the directory. Full log below.
I am behind a router and I have specified custom port list, which are all forwarded on the router, and I can see the incoming connection via wireshark on the ephemeral port so it seems like everything is working in that sense.
Its filezilla 1.4.1. The user has full read+write access to the directory
