You'll be waiting a long time for an answer, Quanah no longer works for Zimbra.My advice would be to use a DNS server & caching Resolver separate from your ZCS server.Ace Suares wrote:Qanah, what is your take on this?

Re: After upgrade to 8.8.8 DNS-cache does not work when zimbra down
In the backup script I put the following:
/etc/init.d/zimbra stop > /dev/null
#
# Kill leftover Zimbras
#
pkill -9 -u zimbra
echo " - Server Down: `date +%T`"
# Stupid DNS cache
su - zimbra -c 'zmdnscachectl start'
#
# Save ldap database, that would be 80GB otherwise.
#
su - zimbra -c '/opt/zimbra/libexec/zmslapcat /opt/zimbra/data/ldap/mdb/'
Now it works again as it should. Not very elegant. How can shutting down the Zimbra server take down the dns cache of the whole server. Not good.

It's not meant to be the DNS cache for the whole server unless you designate it as such, as I've already said, you should use a separate DNS server & caching Resolver if you want your server to work if dnscache goes down for any reason..Ace Suares wrote:Now it works again as it should.

So on what port and IP should that other DNS server run?
Re: After upgrade to 8.8.8 DNS-cache does not work when zimbra down
If you're use another DNS instead of dnscache then I'm assuming it would be on another server on your LAN, would that be the idea? If that's what you're doing then it 's just the same port as usual i.e.53 and obvious you'd need it's IP specified via dhcp or manually on every other machine on your LAN.
