I don't know what's your intent for this.Do you mean when there's a connection to this host,it should open a port to accept the connection,at other time it shouldn't open that port?AFAIK,this is impossible.Though using some tools like PF port forwarding or LVS,you can't see the ports opened on a host but they are really on there,it's nothing you wanted here. Instead you can always open a port on the host and accept the connection,but use firewall (like iptables) to filter the info you wanted and drop the info you unwanted. Opening a port generally need to build a socket server.In perl it's easy to do,see 'perldoc IO::Socket' for the description. -- Jeff Pang <[EMAIL PROTECTED]> http://home.arcor.de/jeffpang/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
