FTP: 450 Can’t Access File

I had this issue as well, and it was related to the data ports being selected by IIS. I set it up to use a specific port range but when my client tried to use passive mode it showed that it was using the wrong port.

This article describes the method for calculating which port it is using. e.g.

227 Entering Passive Mode (x1,x2,x3,x4,y1,y2)

The IP it would be using is x1.x2.x3.x4 and port (y1*256) + y2. I was seeing the wrong values for y1 and y2 so I had to restart "Microsoft FTP Service" to actually get it to recognize the values I had set in the FTP Firewall Settings in IIS.

Alright, I should have done this to start with:

FTPHOST="domain.com"
FTPUSER="xxxxxx"
FTPPASS="xxxxxxxxx"
MEDIAFILE=/path/to/something.enc
if [ -r $MEDIAFILE ]
# File seems to exist and is readable
then
ftp -n $FTPHOST <<END_SCRIPT
quote USER $FTPUSER
quote PASS $FTPPASS
cd backups
bin
put $MEDIAFILE something.enc
quit
END_SCRIPT
fi

I added the remote filename to put, and the bin command - tested and works - hopefully it helps.

Edit: I should explain - the put command will assume that the remote path is the same as the local path if a remote path is not specified (second parameter) - so without the remote path, the file was not found on the remote server.
