I’m starting a new thread, because, my problem appears even in the  
simplest try of RUBY’s ftp.

Here’s a simple attempt to just ftp a file over to one of our UNIX  
servers here at my company. It’s left hanging after the last “end” and I  
have to kill the shell.

C:\workflows\graphics\OneVision\MPC\indexes\6x9\>irb  
irb(main):001:0\> require ‘net/ftp’  
=\> true  
irb(main):002:0\> ftp = Net::FTP.open(‘[quark.bna.com](http://quark.bna.com)’) do |ftp|  
irb(main):003:1\* ftp.login(‘user’,‘passw’)  
irb(main):004:1\> ftp.chdir(‘/home/pb4072’)  
irb(main):005:1\> ftp.putbinaryfile(“lrr095.pdf”)  
irb(main):006:1\> end

Is RUBY’s ftp reliable? Or, what am I doing wrong??

Thanks.

I tried this sequence on my system and it worked:

thor:~ wfs$ irb  
irb(main):001:0\> require ‘net/ftp’  
=\> true  
irb(main):002:0\> ftp = Net::FTP.open(‘thor’) do |ftp|  
irb(main):003:1\* ftp.login(‘user’,‘password’)  
irb(main):004:1\> ftp.putbinaryfile(‘sorted.txt’,‘sortedXmit.txt’)  
irb(main):005:1\> end

the file I used is quite small so the code completed quickly. and I  
verified that the file was transmited.

I am on Mac OS X 10.4.6 with ruby 1.8.4

- you may need passive

- you may not be logging in

- either way you will see what’s happening by doing

here are three commandline scripts i used daily moving tens of thousands  
of  
files around, usage is obivous, never had an issue with any of them:

harp:~ \> ftpls cf0  
drwxrwsr-x 3 457 11111 45056 Apr 20 17:43 cf0-0  
drwxrwsr-x 2 457 11111 954368 Apr 20 17:42 cf0-1

## harp:~ \> ftpput a.rb cf0://cf0-0/

- “/cf0-0/a.rb”

## harp:~ \> ftpget cf0://cf0-0/a.rb

- “./a.rb”

note that you can also use ftp://cf0/cf0-0/a.rb syntax and that any path  
with a  
trailing slash on the command line is interpreted as a directory.

here are the scripts.

```
 harp:~ > cat ftpls

   unless uri =~ %r/^ftp/
     host, path = uri.split %r|:/+|o

   else
     URI::parse uri
   end
 end

 abort "#{ $0 } uri [uris]+" if ARGV.empty?
 user = ENV["FTP_USER"] || "anonymous"
 password = ENV["FTP_PASS"] || ENV["FTP_PASSWORD"] || "removed_email_address@domain.invalid"

 while((uri = ARGV.shift))
   uri = uriparse uri
   Net::FTP.open(uri.host) do |ftp|

good luck.
