I am extremely sorry that I have posted two OT messages today as the lists are my only sources of quality advice. If there are other security mail lists for these types of questions, kindly let me know. Thanks for your understanding in advance. One of our customers insisted us to open up port 4000 to allow them to transfer/monitor/use TCPDUMP. We hestitated. He threatens not to do business with us! Any security advice about TCPDUMP is greatly appreciated. Best regards, Ivan - [To unsubscribe, send mail to [EMAIL PROTECTED] with "unsubscribe firewalls" in the body of the message.]
