In general your DNS servers should not serve domains other than those they are authoritative for.
If you are using Bind (eight and above?) you can use the allow recursion option to limit recursion to friendly ip addresses. For example:
acl our-nets { XXX.XXX.XXX.0/24; }; options { allow-recursion { our-nets; }; } Upgrading the latest BIND version is strongly recommended. bind reference manual: http://www.nominum.com/content/documents/bind9arm.pdf Marlon.Richards () Windalco com wrote:
Hi guys. I know this is the SNORT mailing list but i am just wondering if i could get some help here. I found that my DNS server is being asked to make numerous resolutions of darkprofits.com and darkrpofits.net. None of my internal clients are making these requests. My Sniffer shows me that the requests are being made from outside my network and that my DNS server is making a request for this domain to external hosts. Does anyone know where this may be coming from and how to stop it? ==================================== Marlon Richards Communications Engineer West Indies Alumina Company Kirkvine Works Jamaica Tel#: 876-961-7434 Fax#: 876-961-7464 Email: marlon.richards () windalco com ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
