Bug #8039

DRB/dRuby server throws an exception when probed on its port

Added by kimptoc (Chris Kimpton) over 6 years ago. Updated 11 days ago.

Description

I am not sure if this is a bug or a feature ...

When I use nmap to probe the port that the DRB server is listening on, it throws an exception.

Should the server be more resilient to this and/or have an option to restart itself automatically?

Or is the last code sample I give the suggested usage.

See this stackoverflow issue for sample code and little more info - http://stackoverflow.com/questions/15256619/druby-server-crashes-when-probed-on-the-port-its-listening-on?noredirect=1#comment21525295_15256619

Thanks,
Chris
