The description for `-node` was separated by tabs instead of spaces,
causing it to be incorrectly aligned.

Sean Chittenden c0046e0f30 Acknowledge that we're using GNU make's dialect and rename appropriate 
Makefiles to GNUmakefiles so that non-GNU make(1) will error out.  This
should be a transparent change to the universe of people using GNU make.

sean- e68477688e Merge pull request #1675 from hashicorp/d-dnsmasq-reverse-dns 
Iterate on the DNS forwarding docs
 2016-02-02 15:14:37 -08:00
Sean Chittenden c1c3daed9a Iterate on the DNS forwarding docs 
Specifically:

* add Dnsmasq examples for reverse DNS for most of the RFC1918, 5735, and 6598 netblocks.
* Highlight some example options for dnsmasq that are probably of interest.
* Add a small section on reverse DNS testing
* Break out BINDs troubleshooting with Dnsmasq's troubleshooting

Not an exhaustive sweep, but should be helpful when introducing consul to new environments.

Sean Chittenden ef8bbca48f Continually rebalance client connections 
Introduce a low-level background connection expiration mechanism wherein connections will be recycled periodically based on the size and health of the cluster.

For the vast majority of consul users, this will mean an average connection age of 150s.  For 10K node clusters it will take ~3min for clusters to rebalance their connections.  In the pathological case for a 100K cluster where 99K clients are in the minority talking to 1x server it will take ~26min to rebalance all connections.

It's possibe for clients recovering from a parititon to become fixated on a single server until the server or agent is restarted.  This is of particular interest to long-running environments with stable agents, where `allow_stale` is true, and partitions occur periodically.

Sean Chittenden b216d4c11f Rename clientRPCCache to clientRPCConnMaxIdle, change value 
Increase the max idle time for agents talking to servers from 30s to 127s in order to allow for the reuse of connections that are being initiated by cron.

127s was chosen as the first prime above 120s (arbitrarily chose to use a prime) with the intent of reusing connections who are used by once-a-minute cron(8) jobs *and* who use a 60s jitter window (e.g. in vixie cron job execution can drift by up to 59s per job, or 119s for a once-a-minute cron job).

Sean Chittenden 893f91b0d5 Always seed math/rand on consul startup 
Required for jitter calcs.  This could be done in consul/agent, but this makes it clear it is done only once process-wide.

Sean Chittenden c470553b6b Factor out duplicate functions into a lib package 
Consolidate code duplication and tests into a single lib package.  Most of these functions were from various **/util.go functions that couldn't be imported due to cyclic imports.  The consul/lib package is intended to be a terminal node in an import DAG and a place to stash various consul-only helper functions.  Pulled in hashicorp/go-uuid instead of consolidating UUID access.

Jamie Kelly 08eefe7c31 Edit intro to present Consul instead of Terraform. 
As this is Consul, not Terraform, it makes sense to use Consul in this intro instead of Terraform.
