hello i was learning about ruby and on the book i am reading it shows
the part where i can create a chatserver with Gserver

well lookingon the internet shows the server code everywhere.

but when i am trying to do a chat client it always failed on me.
i wouldl ike that it works like a conection with telnet or with netcat.

here is the failling code:

require 'socket' # Sockets are in standard library

host = 'localhost'
port = 1234

while line = s.gets # Read lines from the socket
puts line # And print with platform line terminator
s.puts gets
end
s.puts "Connection close!!"
s.close


THANK YOU in advance

For me this code fails with this error:
test_socket.rb:6: undefined local variable or method `s' for
main:Object (NameError)

obviously, because you haven't assign anything to s. Do you have a
different version of your program, and what are the errors you are
getting?

Jesus.

I am sorry!!!

here is the failling code:

require 'socket' # Sockets are in standard library

host = 'localhost'
port = 1234

s = TCPSocket.open(host, port)

while line = s.gets # Read lines from the socket
puts line # And print with platform line terminator
s.puts gets
end
s.puts "Connection close!!"
s.close

Well i guess it works now, but there is a problem the code becuase the
cliente waits for the server to reply in order to place more data and
the other way around.

There is a way to be waiting both I/O and react depending on which was
activated with data?

I saw that Select might be an alternative but i havent found an example
that guide me through the SELECT options.

Thank you in advance!
