Help - Linux?

[Knute Johnson]

Would somebody please try this on Linux for me. It works fine on
Windows but hangs on Fedora.

Thanks,

#!/usr/bin/ruby

require 'net/ftp'

def getMetar(id)
metar = Array.new
i = 0
ftp = Net::FTP.new('tgftp.nws.noaa.gov')
puts ftp.login
puts ftp.sendcmd('PASV')
ftp.chdir('/data/observations/metar/stations')
ftp.gettextfile("#{id.upcase}.TXT") do |line|
metar = line
i = i + 1
end
ftp.close
return metar
end

puts getMetar("KBFL")

Thanks very much, any ideas why it doesn't for me?

Not a clue, I'm afraid. You'll need to dig deeper into what's happening on
the network, probably.

Cheers,

Step one: install a command line FTP client. I use "lftp", but there are
others. Then type

lftp tgftp.nws.noaa.gov
lftp tgftp.nws.noaa.gov:~>

If you don't get that prompt, there's something disconnected between
your client and the server. You'll need to talk to your network
adminstrator to diagnose what's broken.

But if you *do* get the prompt, the network is working but the Ruby
client isn't. There's probably something wrong with your Ruby
installation. Reinstall Ruby. Try again

I ran this script:

true && (
set -x
cat /etc/issue.net
ruby -v
cat ftp.rb
/ftp.rb
) >& output.txt

Here's the content of output.txt:

The command line client works just fine. I removed and reinstalled ruby
and the problem still exists. Is there some library I have to install
too for the FTP class?

OK, so it's not a Linux problem it's my Linux problem.

You might want to "gem install ruby-debug", put this at the top of your
program:

require 'ruby-debug'
Debugger.start
debugger #start irb

...and then use "s" to step through each line and see exactly
where the hang-up is. Might be a threading issue.

Les:

I tried this but get the following error

metar.rb:6:in `require': no such file to load -- ruby-debug (LoadError)
from metar.rb:6

There is no ruby-debug package that I can find for Fedora. I tried
loading rubygems.noarch but that didn't help. There has to be something
simple I'm missing here, I just don't know what it is.

Thanks,
