Should I be able to stop a drb server that ends with
DRb.thread.join
by hitting Ctrl-C?
http://segment7.net/projects/ruby/drb/introduction.html says that should work.
It's not working for me.
Maybe there's additional code I need to add to enable that.

What platform? Is you DNS working? DRb performs a DNS lookup to discover your local hostname.
$ cat simple_server.rb
#!/usr/bin/env ruby -w
# simple_service.rb
# A simple DRb service
# load DRb
require 'drb'
# start up the DRb service
DRb.start_service nil,
# We need the uri of the service to connect a client
puts DRb.uri
# wait for the DRb service to finish before exiting
DRb.thread.join
$ ruby -v simple_server.rb

Yes. I verified that by doing a ping from a command prompt on a known
URL. It pinged the correct IP address.

I ran your code and was not able to break out with a Ctrl-c.
Could this be a Windows-specific problem?

I think it is -- I seem to recall being annoyed by this before.
I believe I ended up starting another thread that would do a 'gets'
or something and then kill the other threads after it saw the user
hit the keyboard.
This may also be problematic if e.g. you first hit some other key
besides enter -- I think that cause(s|d) problems.

Try Ctrl-Break.
If that doesn't clear it, Ctrl-c now should.
(Ctrl-Break-c and Ctrl-c-Break alternatives often work.)
Can't point you to an explanation, sorry.

You need to also verify that forward and reverse DNS for your machine are both set up.

Did you get the druby:// line?

The example code doesn't use gets, so I think it is somewhere else.

Yes. It output "druby://volkmann:1081".
"volkmann" is my host name.
Ctrl-Break works for me, but not Ctrl-c.

I'm at a loss then. You'd have to look inside the process and see what its stuck on.

You must be using MSVC-compiled ruby, right?
The reason is ruby doesn't enable handling of ctrl event in
win32 (would need to be corrected).
Ctrl-Break works for you because win32 installs a default handler for
ctrl-break which would kill the process.
But there is no default handler for ctrl-c.
http://www.thecodeproject.com/win32/console_event_handling.asp
There is also a MSDN link I'd like to show here that describes that
ctrl-break has a default handler and ctrl-c doesn't, but I couldn't
find it.

I haven't really followed this thead, but this message prompted me to dig out some 20-year-old Turbo C code for an ancient DOS application. As I recall, ctrl-c interrupt had to be explicitly enabled.
The code I found called setcbrk(1) to enable trap on ctrl-c. Don't know if MSVC has (or requires) an equivalent.
