Subject: net/ftp works manually, fails via cron

Hi all,

Ruby 1.8.2
Solaris 10, Linux 2.6.8

I'm experiencing something odd with net/ftp.  When I run the following snippet 
manually it works fine.  Running the same snippet under cron seems to fail.

I don't get any messages in the log file.  No indication whatsoever that there 
was a problem.  It's just that...nothing happens.  There is no file transfer as 
far as I can see when run via cron.

Any ideas?

Regards,

Dan

# ftptest.rb
require "net/ftp"
include Net

host     = "some_host"
log_file = "ftptest.log"

fh = File.open(log_file, "w+")

begin
    ftp = FTP.new(host)
    ftp.login("djberge", "xxxxx")
    ftp.chdir("local")
    ftp.gettextfile("text.temp")
rescue Exception => err
    fh.puts("FTP ERROR: #{err}")
    raise
else
    fh.puts("Got file")
end

begin
    ftp.puttextfile("upload_test.txt")
rescue Exception => err
    fh.puts("FTP ERROR: #{err}")
    raise
else
    fh.puts("Put file")
end

ftp.close
fh.close
