I'm replacing a DNS cache machine in my environment.
The old machine is still up while I make sure nothing's pointed at it.
The new machine is up and my toasters are pointed at it. That is to
say, /etc/resolv.conf on my toasters only has one entry and it points to
the new machine.
Toasters run CentOS 5.4 32-bit. DNS resolution is working on the
toasters and I have verified that they are talking to the new cache
machine by looking at logs.
My issue is that something in DCC still wants to go to the old cache
machine for DNS. This seems to happen only when DCC refreshes it's info
about what DCC servers to connect to, like when I reboot a toaster.
I've been dredging through DCC documentation and Google but I can't find
anything that would indicate that DCC maintains a separate list of DNS
servers for name resolution.
If I remember right I had to compile DCC to install it because it's not
distributed as a package for CentOS, so my wildest guess is that the DNS
server info was hard-coded into the executable at compile time.
Does anyone have a more sane suggestion?
