Re: Malicious DNS request?
Hi, thanks for your help. I noticed that the requests of those non-exist domain name disappeared yesterday. But the NXDOMAIN record in named.stats keep increasing. ( see attachment) I'm using BIND9.2.5 & BIND9.3.1 on two Solaris box, each box has two CPUs installed. it's found BIND8.4.6 running on one CPU could reach the throughput of BIND9.*.* running on two CPUs. Could we improve server throughput or lower lower the effect of those requests on NXDOMAIN? Joe __________________________________________________ Do You Yahoo!?

yes. but "we" isn't nanog. can you take your bind-specific questions to a bind-related mailing list or newsgroup? www.isc.org has pointers. -- Paul Vixie
Has anyone had any experience using Network Mitigation devices like the Cisco Guard XT 5650? I am looking to install one in our network and would like to know if anyone has used the Cisco device? thanks
Do you have amny information about last Microsoft problems with security patches? We can see, how one of last updates broke MTU discovery (not totally, but it restricts number of discovered pathes so servers tsop working in a few days). And, amazingly, no one published this problem.
There is discussion on ntbugtraq http://www.ntbugtraq.com/default.aspx?pid=36&sid=1&A2=ind0505&L=ntbugtraq&T=0&O=D&F=N&P=192 ---Mike At 04:43 PM 17/05/2005, Alexei Roudnev wrote:
