I used shooting_star to create an Chat Application. Ref:- http://github.com/genki/shooting-star Following are the REQUIREMENTS of the shooting_star

• Linux or xBSD OS having epoll or kqueue.
• Increase ulimit of nofile up to over 100,000. (edit /etc/security/limits.conf file.)
• prototype.js 1.5.0+
• Ruby 1.8.5+
• Ruby on Rails 1.2.0+

My Local Configuration are

O.S >> Linux
Ruby >> ruby 1.8.6 (2009-08-04 patchlevel 383) [i386-linux]
Rails >> 2.3.4
shooting_star >> 3.2.7
prototype.js >> 1.6.0.3

My Server Configuration are

O.S >> Linux
Ruby >> ruby 1.8.6 (2009-08-04 patchlevel 383) [x86_64-linux]
Rails >> 2.3.4
shooting_star >> 3.2.7
prototype.js >> 1.6.0.3

I just want to know what is the problem why it's not working on server if everything is fine in local.

If the above code is relying upon the built in Ruby Digest library and not a custom MD5 library the authors wrote themselves, it should be more like:

MD5.hexdigest("event-init-flash-#{Asteroid::now}")

The MD5.new method takes no parameters. If this isn't your code, you might want to file a bug report.
