Dear NSD users, Here is the release candidate for NSD 3.2.15. This comes with ILNP support, NSD-RRL and different TSIG initialization (it fails if it can't find no suitable algorithms, instead of can't find 'one of the'). Plus some bugfixes. The NSD-RRL implementation is based on the work by Vixie and Schryver. However, because of the code-diversity argument that is at the basis...

...advise how to use Response Rate Limiting on a server which has multiple NSD server processes (nsd.conf server section has server-count > 1). We have a problem with NSD v3.2.16 repeatedly unblocking and blocking again a single source which is flooding positive queries at a ~steady 700 qps rate. rrl-ratelimit setting is the default 200 qps. The unblock-block happens multiple times a minute. This is causing false negatives: NSD bursts out 200 responses on every unblock: Nov 6 10:11:18 dnstest1 nsd[6881]: ratelimit block demo.funet.fi. type positive target 193.166.5.0/24 query 193.166.5.1 NS...

I can't seem to find anything clear on this, but is the C7 version of BIND 9.9 built with Request Rate Limiting? -- Mark Haney Network Engineer at NeoNova 919-460-3330 option 1 mark.haney at neonova.net www.neonova.net

Hello, Lutz Donnerhacke implemented DNS-Dampening. http://lutz.donnerhacke.de/eng/Blog/DNS-Dampening The implementation is available as patch for BIND9 only. He told me that there is an other method preferred by the nsd developer. It's called "Response Rate Limiting". May one describe the idea behind rate limiting and compare it with Lutz' solution? Thanks. -- Andreas

The command "smbclient -L localhost -U%" shows the right info. I'm doing something wrong?. C...
