I have some questions about caching nameservers. My home PC is on dhcp that changes IP address every 12 hours. I also have registered at no-ip.org, so that I can connect from the PC at work using a named address. However nscd does not update its cache. I have set "positive-time-to-live" to "3600", but that doesn't seem to have any effect. I also set "persistent" to "no", so that restarting nscd DOES get the changed IP address. What is the difference of having caching-nameserver installed with named running and having nscd running in addition? There is also a problem with ssh, if nscd is off, but named running, logging in via ssh from my home PC to my work PC takes a long time (I presume, this is because of reverse DNS lookup). With nscd on, it is immediate. Has the caching-nameserver no effect at all? Regards -- Gérard Milmeister Langackerstrasse 49 CH-8057 Zürich
