Good day all- I have now upgraded to Bind9 9.4.3-P3 due to the DoS vulnerability (< http://lwn.net/Articles/344008/rss >). However this upgrade has not "cured" the fact that approximately on July 27, 2009, my Bind9 prior version in that server stopped resolving domain names with rDNS 74.208.x.x --without any obvious reason. As a matter of fact, from within that server environment I am not able to ping domains within that IP block. Performing an intensive nmap scan of one IP in that domain, saving the results into an XML file, and subsequently feeding that file to zenmap (< http://nmap.org/zenmap/ >) shows a broken connection from this particular server to the IP in the 74.208.x.x block. nmap -T4 -A -v -PE -PS22,25,80 -PA21,23,80,3389 -oX nmap_74.208.x.x.xml 74.208.x.x As a result I have added an OpenDNS name server to fulfill the role of slave since the issue appears to be local to the server. Any ideas/suggestion on what may be causing this issue will be welcomed. Thanks in advance for your consideration. -- Jose R R http://www.metztli-it.com --------------------------------------------------------------------------------------------- IBM Lotus Symphony supported on GNU/Linux, Mac OS, and Windows. --------------------------------------------------------------------------------------------- Daylight Saving Time in USA & Canada starts: Sunday 08 March 2009 --------------------------------------------------------------------------------------------- -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
