I just updated the DNS record (ns1
, ns2
, ns3.myhostingcompany.com
) for a site I've got hosted, but I still get the domain registrar parking page.
I'd like to see if the problem is Ubuntu's cached DNS records.
Is there a way to clear Ubuntu's DNS cache? (if such a thing exists?)

Look at Mike Shultz' answer.
For 11.10 and below
Ubuntu doesn't cache dns records by default so unless you've installed a dns cache there isn't anything to clear.
DNS records are likely cached by your provider's DNS servers so if you want to check if the DNS changes you made were successful you can interrogate a DNS server from your domain hosting service with dig:
dig -t a ns1.myhostingcompany.com @domain_registrar_dns_server
It you want Ubuntu to start caching dns I recommend installing
pdnsd
together withresolvconf
.nscd
is buggy and not advisable.
