Tcp socket error

Ruby
1

I’ve had no problem with this program with windows 2000 and xp. However
I bought a computer and vista comes with it.

With Ruby 1.8.6-i386-mswin I get the following error:

require ‘net/ftp’

ftp = Net::FTP.new(‘ftp.nwlagardener.org’)
ftp.login(“nwlagard”,“*******”)

p ftp.status

ftp.chdir(‘web’)
p “dir changed”
p “------------”
files = ftp.list
files.each {|x| p x}
ftp.gettextfile(‘cis.html’,‘cis.html’)

ftp.close

ruby ftp_learn.rb
