How would I find out what port named runs on (so I could open that port

It normally runs on port 53, unhelpfully labelled "domain" in

I found it. It is port 53. Now I have a new problem. I tried to list
my DNS server (that I've been working on this week) as an optional third
DNS server for my domain at my registrar's website. I have a record for
ns.espersunited.com in my DNS setup on my server box. The problem is
that nobody knows who ns.espersunited.com is because my current DNS
hosting service (Yahoo SmallBusiness) doesn't allow entry of NS records
in their customer DNS settings and my registrar (1accredited.com) won't
accept an IP address as a nameserver. I might try listing
bullet.espersunited.com as a nameserver (ns.espersunited.com has a CNAME
record pointing to bullet.espersunited.com), but I'm not sure it will
work. Any suggestions of how to get my DNS server noticed
You can only run an externally visible DNS server on a *completely*
static IP. If you have a static IP for your server, you then have to ask
your domain registrar (for espersunited.com) to register your DNS server
with the name(s) you wish, I recommend keeping to the standard
nsX.domain. If you ever need to change the IP address for your DNS
server, you need to ask your registrar to do this.
Only once your DNS server is registered can you use it as a server for a
domain. Before you do any of this, however, I *strongly* recommend you
get very familiar with DNS and understand exactly what you are doing. I
cannot emphasize this enough, since if your DNS server is not running
properly you can become the target of various attacks and/or the
domain(s) you are servicing may start failing.
DNS isn't trivial.
HTH,
Chris
