I have spent several hours trying to workout why drb ruby will not allow  
a remote pc to connect to my server to pull objects…  
Here’s where I stand with the problem:  
Debian server is on 192.168.0.2 running ruby 1.8.2  
Windows client is on 192.168.0.37 running ruby 1.8.4  
I know the versions are different, but I’m worried that updating Debian  
might break some packages… I’m still looking into that part… if I  
could at least get it to connect I would be happy

run drbtest.rb on debian server, do the following tests,  
run drbclient from debian server: connects  
run drbclient from a windows machine: does not connect  
run telnet to the drb port on debian server: does not connect  
run telnet to the drb port, but have netcat running: connects

for some reason I can’t get access to that port from another machine  
with ruby running. I have tried to create an ACL list, but it doesn’t  
seem to help. If anyone can point me in the direction of documentation,  
or a code snippet that might fix the problem, it would be greatly  
appreciated.

## Server code snippet:

require ‘drb’  
require ‘drb/acl’

class TestServer  
def doit  
“Hello, Distributed World”  
end  
end

acl = ACL.new(%w[deny all  
allow 192.168.0.\*  
allow localhost  
allow 127.0.0.1  
] )

DRb.install\_acl(acl)

aServerObject = TestServer.new  
DRb.start\_service(‘druby://cindy:88585’, aServerObject)  
DRb.thread.join # Don’t exit just yet!

## Client code snippet:

require ‘drb’  
DRb.start\_service()  
obj = DRbObject.new(nil, ‘druby://cindy:9999’)

# Now use obj

p obj.doit

What error message are you getting when you try to connect to the  
server? I remember I had a similar problem a while back. It turned out  
to have something to do with not having the correct config in my  
/etc/hosts file, I think. In other words, it wasn’t a drb problem, but  
something with how the network addresses were getting resolved.

Sorry I can’t remember more. I think I remember someone having a  
similar issue a few months ago on this list, so you might want to search  
the archives.
