More on DRB & OpenSSL

[Nathaniel Talbott]

OK, I've tracked down my problem with DRb and OpenSSL a bit more; perhaps
someone can help me out now, as I'm quickly getting out of my league. Here
are test client and server scripts that will show the failure. To run them,
you'll need the latest DRb from ruby CVS
(http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/lib/drb) installed (and of
course the OpenSSL extension).

s.rb:

require 'drb'
require 'drb/ssl'

class Front
def small
puts "Called #small"
"Hi!"
end

def large
puts "Called #large"
"a" * 1000 * 500
end
end

url = ARGV[0] or raise "You must supply the url"
config = {
:SSLCertName => [ ["C","US"], ["O","someplace"], ["CN", "Temporary"] ],
:verbose => true
}
DRb.start_service(url, Front::new, config)
puts "Listening on #{url}"
DRb.thread.join

c.rb:

require 'drb'
require 'drb/ssl'

url = ARGV[0] or raise "You must supply the url"
DRb.start_service
front = DRbObject::new(nil, url)
puts "Connected to #{url}"
p front.small.size
p front.large.size

s.rb output:

ntalbott@proxytest:~$ ruby -vw s.rb drbssl://localhost:5777
ruby 1.8.0 (2003-08-04) [i386-linux]

If there's any other information I can provide, or anything else I can do to
help debug this, please let me know. Also, if there are other places I
should ask this question, please let me know that, too.

Thanks,

I've noticed that there is always a strange silence on DRb questions. I
wonder how many people really use it. I love it, well, I love what I
know about it. The docs seems a little hard to come by.

I scratched together some notes at:

http://www.eng.cse.dmu.ac.uk/~hgs/ruby/dRuby/

but I don't think I got everything right. Feel free to use this if
it is of any use at all. That's why I wrote it somewhere visible.

I've not got into SSL with this yet, I'm using SHA1's of
(nonce + passwd)s to authenticate messages at the moment.

This is something we should change -- anyone want to work on an
initially wiki-based (english) documentation of dRB with me? It's
something I could enjoy delving deeply into, and I think that some
extensions could be useful as well.

I'd host the wiki unless someone else really cares to -- I've a server
on a dual T-1 to offer, and a DS-3 coming in October. Bandwidth and CPU
are cheap ;-)

I think this'd be a very Good Thing, especially if it the DRB homepage
referred to it.

I'm happy to be a wikignome for it.
Cheers,
Euan
