How can I tell what process is sending packets from a particular port (udp/55613)? X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 30 Apr 2006 20:52:08 -0000 Dear FreeBSD, I see outbound packets from udp/55613, one every 5 seconds, to a single non-routable (10....) IP, with destination port increasing by 1 with each packet, with expected ICMP Destination net unreachables from an upstream router. AFAIK, there's no reason for this and I don't like it - how can I tell which process is sending the packets? With thanks in advance, boink
