hi again, with filezilla and winscp same thing happened. clients can't retrieve directory. directory is set to client0:web15 I dig some logs and found this; it seems like someting block retrieve directory?
This is usually that you need to set a passive port range, or that it is blocked in a firewall or needs forwarded in NAT. See here.
thank you very much. problem solved. but your link is broken here is the working link; https://www.faqforge.com/linux/cont...ange-in-pure-ftpd-on-debian-and-ubuntu-linux/
Sorry about the link, I'm on a smartphone and the page pulled up in Google's amp thing, so I tried to manually fix the URL back to the original.
