We currently have 1 live WingFTP server up and running on Ubuntu 10, this server has some NFS shares that are mounted to the server and WingFTP is controlling FTP access to these shares, this is working just fine.
We're currently installing a second WingFTP server that is going to be serving FTP access to the same shares. For testing I currently have it running with the same settings as the one that's working, but whenever a user tries to connect who should have access to one of the nfs shares, the user gets this error when they try to connect:
530 PASV command unavailable due to EPSV ALL request be sent. Please reconnect using PASV.
As a test I even cloned the current functional server, and this server gets this error as well. It almost seems as if having 2 WingFTP servers trying to serve up the same NFS shares doesn't work.
Does anyone have any experience with the error above?
