Subject: net-smtp timeout error

Hi,

Ruby 1.8.6-p114
RHEL 3

I've got two RHEL3 boxes, alpha and beta. On the alpha box, the
following script works fine. On the beta box I get a timeout error
with the same script. What's happening?

require 'net/smtp'

host    = 'mailhost.foo.com'
port    = 25
to      = 'some_user@foo.com'
from    = 'httpd@foo.com'
subject = 'test'
body    = 'hello world'

Net::SMTP.start(host, port, host){ |smtp|
   smtp.open_message_stream(from, to){ |stream|
      stream.puts "From: #{from}"
      stream.puts "To: " + to.to_a.join(', ')
      stream.puts "Subject: #{subject}"
      stream.puts
      stream.puts body
   }
}

Result:

/usr/local/lib/ruby/1.8/timeout.rb:54:in `new': execution expired
(Timeout::Error)
        from /usr/local/lib/ruby/1.8/net/protocol.rb:206:in `old_open'
        from /usr/local/lib/ruby/1.8/timeout.rb:56:in `timeout'
        from /usr/local/lib/ruby/1.8/timeout.rb:76:in `timeout'
        from /usr/local/lib/ruby/1.8/net/protocol.rb:206:in `old_open'
        from /usr/local/lib/ruby/1.8/net/smtp.rb:393:in `do_start'
        from /usr/local/lib/ruby/1.8/net/smtp.rb:378:in `start'
        from /usr/local/lib/ruby/1.8/net/smtp.rb:316:in `start'
        from smtp_test.rb:12

I did validate that the /etc/resolv.conf and /etc/protocols files were
the same on both boxes.

This some sort of sendmail config issue? If so, any ideas what it
might be?

Regards,

Dan
