Hello Travis,

 

Install and/or Run IPTRAF if you have it, otherwise use tcpdump and "home" in on the port/source ip. Then ask you ISP to block them

 

Cheers,

 

Pieter

Subject: Unidentified Network Traffic

I have a DSL Internet connection at location A.  I have static public IP's that are routed to location B through an ISDN line.  Location A uses a DSL router that is connected to a Red Hat PC that sends traffic to and from location B via an ISDN modem.  There is something going to one of my ip addresses at location B from the Internet.  It constantly sends whatever it is from the Internet.  How can I figure out where this is coming from so that I can stop it?  It is so bad that it floods the ISDN router at location B and stops all traffic, except the unknown traffic, from passing through.

 

Thanks for you help,

Travis
