Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
So generally it seems impossible to have both DNS seeds running on same IP address. Too bad. Ok, I'll switch to serving only testnet DNS on this server for now, as this seems to be a much bigger problem than mainnet. Later I might buy second IP to setup mainnet DNS also.

We'd used an approach like that previously and I believe it produced fairly bad load imbalances, especially since some resolvers only pass on a single result.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
A simple hack would be to crontab up a couple of dig scripts that every minute 'dig' (dig's output is in bind zonefile format) the bitcoin-seed and write the results to two zonefiles that bind can then serve. Basically dig @127.0.0.1 -p 5353 > zonefile1.zone dig @127.0.0.1 -p 5354 > zonefile2.zone pkill -HUP named Ugly, but should work.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
I maybe have made this suggestion in the past, but why don't we teach the seeder (or maybe even plain bitcoind) how to write a zone file and then use matured DNS servers to serve this zone? I admit I never ran my own DNS so I'm not sure if that can work -- but to me it sounds like the easiest approach plus everyone can just use stock server software.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
I don't think it would be too hard to add support for a option to the seeder "for non-matching requests, forward to other DNS server at IP:PORT", so you could cascade them.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
No, I don't think so. The problem is the 'aa' flag is missing (see the 'flags' section in dig). Perhaps if you could suppress the authority records the recursor would give up and just accept the non-authorative answer, but that isn't a good solution even if it might work for some resolvers.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
Hi Alex, I think the problem is with my suggestion to use bind forwarding.. basically bind is stripping off the authorative answer bit in the reply.. this causes the recursor to go into a loop chasing the authority server which again returns a non-authoritve answer with itself as the authority again. I'm not sure if this can be fixed without hacking the bind src, so maybe it wasn't such a great suggestion in the first place. Basically I think if bind was returning authorative answers it would work, but I can't see any way to make that happen in the bind configuration.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
Hi Peter I've setup DNS seeds myself a week ago, at testnet-seed.alexykot.me and bitcoin-seed.alexykot.me, but there is a problem with DNS settings that we with Andreas couldn't sort out quickly. The problem itself is that I can reach my nameserver and get dnsseed response if I query it directly with dig @node.alexykot.me testnet-seed.alexykot.me dig @node.alexykot.me bitcoin-seed.alexykot.me But when I try nslookup testnet-seed.alexykot.me - it fails. I guess the problem is in my DNS settings but I can't figure out what is it. S o could you share how you configured DNS for your seed to help me debug mine ?

Can you verify if your copy of the seeder contains the commit 8dcc006e6256cb746c2b025daf3df41baa26353e ? It fixed a bug that has exactly the symptoms we currently see. I wonder if the restart of your server actually changed/fixed anything. If you got a SERVFAIL this may be because you were traveling through parts of the world that can't reach your server.

Re: [Bitcoin-development] testnet-seed.bitcoin.petertodd.org is up again
You're very quick to point at others. Especially since they run software that had the time to mature for about 30 years, and the protocol didn't really change since then... The last time it didn't work, the bug -- non RFC-conformance -- was on the bitcoin seeders side. ISPs do weird things with DNS, but usually they stay within the RFC. Anyway, without logs we don't have a chance to debug this issue. Any chance you could add simple logging to the seeder? DNS via HTTP? Never heard of that, at least it sounds weird as well.

There are no logfiles for DNS requests. I just checked on EC2 and my cellphone internet connection here in Tel Aviv; both work fine. My best guess is that your DNS resolver locally or at your ISP is unable to deal with the fact that the second DNS seed serving the domain testnet-seed.bitcoin.petertodd.org happens to be down right now. Note that some ISP's appear to both run buggy DNS servers, and redirect traffic meant to go to Google's 8.8.8 and 8.8.4.4 DNS servers to their own servers.

FWIW That said, keep in mind the github discussion(1) that was had: if all the DNS seeds being down breaks your application, your application is broken and insecure. The only exception is initial startup, and even then you should have fallbacks such as hardcoded node lists and manual peer entry. If for some reason you really do need instant startup, run your own centralized high-availability/low-latency nodes; either way you're depending on a centralized resource. 1) https://github.com/bitcoin/bitcoin/pull/4203 -- 'peter'[:-1]@petertodd.org signature.asc Description: Digital signature -- "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
