Now notice no outgoing DNS traffic.
If you want to be certain 'nscd' is doing the caching, stop it, then repeat the exercise and notice outgoing DNS traffic on every ping command.
It would not work in any of my system, I have always set a DNS cache server. Previously I used bind, now I use dnsmasq.
I would have to disable that and reconfigure my network.
Hmm, without knowing your config, you still ought to be able to see/tcpdump the DNS traffic somewhere. If dnsmasq is accessed via 127.0.0.1, just run tcpdump on 'lo'.
If dnsmasq doesn't run locally, run tcpdump on whichever interface is used to access it.
Carlos's point is that nscd might not be doing the cacheing on his network because he is explicitly running some other services to handle this, and therefore his results would prove nothing about nscd. I don't think he meant that the actual commands wouldn't work. Your tests work for me, but I too have no idea who is doing this caching, as nscd -g shows no difference comparing before or after, and cache hit rate remains 0. I run bind as well, on my gateway box, so it might be in there. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
