Eventmachine talk - Jul 2008 - local source port/address bind()ing for TCP

Hi there,

I''ve been digging around the code extensively and I can''t seem
to find
a way to bind EventMachine''s TCP client on a specified local port and
interface.

Am I missing something here?

As a point of reference, this ruby snippet works just fine (and
illustrates the basic idea):

-snip-

$ ruby << _EOF_
require ''socket''
sd = Socket.new( Socket::AF_INET, Socket::SOCK_STREAM, 0)
sd.bind( Socket.pack_sockaddr_in( 9999, "127.0.0.1" )  )
sd.connect( Socket.pack_sockaddr_in( 8888, "127.0.0.1" )  )
sd.write("hi there\n")
sd.close

_EOF_

-/snip-

-snip (Consider this the "Server" I want to talk to)-

$ nc -v -l -p 8888
listening on [any] 8888 ...
connect to [127.0.0.1] from localhost [127.0.0.1] 9999
hi there

-/snip-

In short, ''bind'' only really seems to get exposed by
EventMachine for
UDP datagram sockets. I need to do this sort of thing with TCP to
speak a particular protocol through someone''s paranoid firewall.
It''s
also an option I''d really like to support in some generalized network
testing tools I''m writing around evma.
