I was going to try and use ruby to transfer files to an FTP site so I  
figured I would try some simple code in the irb.

ftp = Net::FTP::new(‘[my.url.com](http://my.url.com)’)  
ftp.login(‘login\_id’,‘login\_pass’,nil)  
ftp.chdir(‘data’)

all goes fine but at this point I have tried all of the following and  
get the same errors

files = ftp.list(‘data’)  
files = ftp.dir(‘data’)  
files = ftp.dir(dir = nil)  
files = ftp.nlst(‘data’)

Net::FTPPermError: 500 Invalid PORT command.

I know that there are files that should have been listed.

I have Googled the error and looked on the news group to get a solution  
and haven’t found one or was not smart enough to understand the one  
that was given.

Any help would be appreciated.
