Below is the result of a 10 minutes hack to create a simple HTTP-connect
tunnel. I’m not closing sockets since I assume that at some point one end
will close its connection and the thread will die with some exception
such as Errno::EPIPE, Errno::EHOSTUNREACH or EOFError, so that the
sockets are GC’ed (and closed) some time in the future.
Is this assumption correct?
require ‘socket’
port = (ARGV[0] || 6666).to_i
server = TCPServer.new(‘localhost’, port)
puts “Binding to #{port}”
while ( session = server.accept )
Thread.new(session) do |s|
line = s.readline(“\r\n”)
break unless line =~ /CONNECT\s+(.+):([0-9]+)\s+HTTP/1.(?:0|1).*/
_host, _port = $1, $2
while line != “\r\n”
line = s.readline(“\r\n”)
end
out = nil
begin
out = TCPSocket.new( _host, _port.to_i )
rescue
s.print “HTTP/1.0 500 Connection could not be established\r\n\r\n”
break
end
s.print “HTTP/1.0 200 Connection established\r\n\r\n”
loop do
ready = select [s, out]
ready = ready[0]
ready.each do |x|
case x
when s
data = s.sysread(512)
out.syswrite data
when out
data = out.sysread(512)
s.syswrite data
end
end
end
end
end
