I’m trying to start up webrick on my NT box.

irb(main):003:0\> s = WEBrick::HTTPServer.new(:Port =\> 4567)  
Errno::EBADF: Bad file descriptor  
from c:/ruby/lib/ruby/1.8/webrick/log.rb:40:in `write' from c:/ruby/lib/ruby/1.8/webrick/log.rb:40:in`\<\<’  
from c:/ruby/lib/ruby/1.8/webrick/log.rb:40:in `log' from c:/ruby/lib/ruby/1.8/webrick/log.rb:85:in`log’  
from c:/ruby/lib/ruby/1.8/webrick/log.rb:51:in `info' from c:/ruby/lib/ruby/1.8/webrick/server.rb:55:in`initialize’  
from c:/ruby/lib/ruby/1.8/webrick/httpserver.rb:24:in `initialize' from (irb):3:in`new’  
from (irb):3  
from :0  
irb(main):004:0\>

I’ve tried a few other port numbers picked at random, but no joy. I also  
get a similar problem if I just try to open up a TCP socket, so this  
seems related:

irb(main):006:0\> s = Socket::TCPServer.new(45673)  
Errno::EBADF: Bad file descriptor  
from (irb):6:in `write’  
from (irb):6  
from :0  
irb(main):007:0\>

Could anyone suggest what the problem is?

Thanks,  
Benjohn

Oddly, none of this happens when I run directly from irb (I’ve not tried  
a stand alone script). I’ve only encountered it when I’m using the fxri  
interface, so I’m just using the vanila comand line.

Strange.

Thanks,
