Re: [Oscar-devel] dnsmasq

[Jeremy Enos]

I like this idea... I remember trying to find a piece of software w/ this functionality. However, I also remember serious performance considerations in having a local /etc/hosts for MPI purposes. I could try to dig up details if you're interested. But the resulting action was having an /etc/hosts file on each compute node to prevent it from hitting a DNS server to find out about fellow nodes.

Basically, it reads /etc/hosts on the node it is run, and serves dns queries
(forward and reverse) from it.  If a query for something not in /etc/hosts
is asked for, it goes just proxies the query out.  It has lots of good
features in it, but mostly, it would mean *not* having to propogate
/etc/hosts to every host every time something changed.  This would be
goodness IMHO.

There is no silver bullet.  Plus, werewolves make better neighbors than
zombies, and they tend to keep the vampire population down.
