comment Why don't my server query the 2nd entry in my resolv.conf?
Our local resolver does work, does perform recursive lookups, and does cache the results. However, when I run namebench to compare the speed of a large number of lookups, the public DNS server outperforms it every time, as it already has a number of queries cached. The catch is, as you say, "lower latency responses after resolved domain names are cached." It's the "after they're cached" part that is causing the issue. Most of the domain lookups from our servers are first time lookups. That's why I'm (still) looking for a way to autoquery a 2nd DNS server after failing to resolve on the 1st.

Thanks, Daniel. This answers the question (and I will mark it as such). Do you know of a way to get the functionality I'm looking for? If nameserver #1 doesn't time out, but doesn't resolve, to query a subsequent nameserver?

It's not that the local DNS server is "too slow," it's that it's slower than the remote one based on a namebench test. It works, but I want things to work faster. :)

K - I'll test this out soon and mark it "accepted" when I confirm. Thanks. :)

comment How to Route Internal Traffic on a 2nd NIC without a Default Gateway
No, it's not currently set up like this yet - our ISP is migrating us to new IPs, so both NICs are busy servicing two different public IPs. Once the migration is finished, I wanted to set up the internal network. I'll give this a shot once the hardware is avail. Is it the NETWORK=192.168.1.0 that lets it work, even though the GATEWAY= is commented out?

Then what should the /etc/sysconfig/network-scripts/ifcfg-eth1 file look like? I tried testing this once before with the following settings, but could never get two test boxes to see each other: DEVICE=eth1 BOOTPROTO=static HWADDR=00:06:xx:xx:xx:xx IPADDR=192.168.1.5 NETMASK=255.255.255.0 ONBOOT=yes #GATEWAY= NETWORK=192.168.1.0 TYPE=Ethernet USERCTL=no IPV6INIT=no #PEERDNS=yes

comment Not sure how to handle routing with 2 NICs on 2 different subnets
I was hoping that was the case, but wanted to make 100% sure before trying anything on live servers. :)
