I setup a testnet DNS seed using Pieter Wuille's bitcoin-seeder, with
some simple modifications for testnet. It's at
testnet-seed.bitcoin.petertodd.org I also created
static-testnet-seed.bitcoin.petertodd.org which currently has a single A
record pointing to a testnet node I'm running to bootstrap the seeder
itself.
Everything is running on a dedicated Amazon EC2 micro instance. Just
IPv4 is supported right now as EC2 doesn't support IPv6; even tunnels
are broken. I also haven't setup tor yet. I can do both if there is
demand.
I guess the next step is to create a new strTestNetDNSSeed in the
satoshi client, although it'd be better if at least one more person had
a testnet seed to include in the list. Probably best to leave IRC
enabled too.
Also, FWIW, it looks like the pnSeed list is way out of date...
Pieter: Have you written any start/stop/monitoring scripts for the
seeder? My mods are at git://github.com/petertodd/bitcoin-seeder.git in
the "testnet" branch. I'll send you a pull request once it's had some
testing.

How long do you plan to run this? Indefinitely [presuming there is
interest and users]?

Yes, IRC must remain enabled

Yes. Usually nanotube does the update when poked. That can happen,
or something different.
A nice alternative might be a simple script that transforms Pieter's
seeds.txt into pnSeed[]

Indefinitely. It's a pretty cheap thing to run, about $7.5/month. If
anyone else wants I can give them a machine image copy easily too.

seed.txt? You mean the dumpfile produced by bitcoin-seeder? That has
uptime info, although only a months worth if I understand it correctly.
pnSeed probably should be filtered with SORB's dynamic ip list or
similar too, and additionally add an expiry time. (1 year?)

Cool. ACK on adding your seed to the ref client.

Correct.

That's fine. The main point was to create something scripted and
repeatable. Then pnSeed[] becomes easier to maintain _and_ easier to
audit. Right now it is a bit opaque with a list of hex constants. A
script or makefile rule could do
cd src
../contrib/gen-seeds.py > seeds.h
and seeds might look like
#ifndef __SEEDS_AUTOGEN_H__ etc.
unsigned int pnSeed[] = {
0xABCD1234, /* IP addr 12.34.56.78 */
};
I think Satoshi liked them opaque and not easily searchable, so
printing the readable IP address in a comment may not be desired.
Anyway, that output would make updating the list more transparent and
easy to maintain.

It has information about all non-banned IPs that were ever connected to
succesfully. The connectability% is a decaying average, with a time
constant of up to a month, though.
I have a script ready which combines one or more seeds.txt's data into a
pnSeed[] array C source code, by the way. I'll add it to the repository.
