远程获取其他主机信息，适于远程主机管理（实际应用时添加必要的验证、加密、端口过滤等内容）。

server1:   srv1200read.pl  zclient2200.pl

server45: srv2200read.pl

server1监听1200端口，server45监听2200端口

server1向server45的2200端口发送消息，server45处理后向server1的1200端口返回处理后内容。

##srv1200read.pl 
use IO::Socket;
use IO::Select;
$socketread = new IO::Socket::INET (LocalHost => 'server45',
                              LocalPort => 1200,
                              Proto     => 'tcp',
                              Listen    => 5,
                              Reuse     => 1,
                             );
$read_set = new IO::Select;
$read_set->add($socketread);
while (1) {

        ($new) = IO::Select->select($read_set, undef, undef, undef);
