However, as tomcat attach by default only to 127.0.0.1 address, you already know what the ip of command sender is. It's 127.0.0.1, aka localhost.
You can write a standalone application that listen to :8005 but does not respond, in the hope that sending process will be stuck waiting for acknowledgement of shutdown. Then immediatly issue a netstat to see which applications are connected where. As someone suggested, logging info from iptables can be usefull, but i don't know iptables in details :) > As for the second bit--I installed tomcat myself. > >> From: David Delbecq <[EMAIL PROTECTED]> >> Reply-To: "Tomcat Users List" <users@tomcat.apache.org> >> To: Tomcat Users List <users@tomcat.apache.org> >> Subject: Re: Tomcat mysteriously shuts down >> Date: Thu, 15 Feb 2007 14:08:33 +0100 >> >> Normally, tomcat shutsdown is a localhost running application sends a >> shutdown command to the localhost server command port (8005).
