Subject: Re: Ruby Newbie's Question: Sockets - searching for equivalent to a perl  programme

Thanks Guy,

now, while the perl programme works perfectly fine, I have difficulties
with the TCPSocket version. I tried:

irb(main):029:0* t=TCPSocket.new('localhost',8530)
#<TCPSocket:0x163000>
irb(main):030:0> t.addr
["AF_INET", 61501, "127.0.0.1", "127.0.0.1"]
irb(main):031:0> t.peeraddr
["AF_INET", 8530, "127.0.0.1", "127.0.0.1"]
irb(main):032:0> t.puts("#$(netutl-client-msg-header
netutl-client-msg-type/gui-blocking \"Perl client\")\r\n")
nil
irb(main):033:0> t.puts("(ivel-window-get-active-vref)\r\n")
nil
irb(main):034:0> t.gets
Errno::ECONNRESET: Connection reset by peer
	from (irb):34:in `gets'
	from (irb):34
irb(main):035:0> 

I also tried recvfrom instead of gets, no matter how, each time the
connection gets reset. 
The I replaced 'localhost' with the servers actual IP address, getting
the same result.

The perl programme always gets a correct answer from the server.
