Rclone serve FTP failing

Help and Support
1

Been trying to use the Rclone FTP serve command (rclone serve ftp) with a Java application I use.

Command I’m using:

rclone serve --user=$USERNAME --pass=$PASSWORD --addr=$HOSTNAME:$PORT ftp -v gcrypt:/other/backups/

Log from -v option.

The application connects, “uploads” the backup, and considers it a success even though it failed. Any ideas what I’m doing wrong?

sounds like you’re using the PORT when you should be using PASV in the client java application. Is there a NAT or firewall between the FTP and the java app?

dial tcp 172.18.0.2:33894: connect: connection refused

Probably yeah. I’ll look more into it. :confused:

4

you should be able to specify the transfer type in the application to PASV which will connect through the NAT/FIREWALL.

Problem is it’s a Minecraft Java plugin and I don’t feel like changing the source lol. Don’t worry about it.
