can NOT sync in testnet #281

Open bxlkm opened 5 years ago

bxlkm commented 5 years ago

Hi,

When I start a namecoin node with testnet=1, it seems it can't find a valid peer to sync. So is this testnet chain still valid? or if anyone could provide me a valid node, that will be great! VERSION: 0.16.3

2019-02-13 07:31:26 0 addresses found from DNS seeds 2019-02-13 07:31:26 dnsseed thread exit 2019-02-13 07:32:19 Adding fixed seed nodes as DNS doesn't seem to be available.

Thanks!

You can use addnode namecoin-cli addnode testnet.node.ip.address add

testnet.namecoin.org
31.45.121.24
45.33.65.68
51.68.251.200

Last one is mine :)

I`m not aware about dns-seeder for namecoin, it would be best option to run one.

We do have multiple seeds for mainnet, and they seem to be working (just did a quick test). For testnet we have one (dnsseed.test.namecoin.webbtc.com), which seems to not work. I'm happy to add more if someone is willing to run testnet seeds.

@domob1812 you probably need point some peers that seeder can start with, we also need add it (seeder) to code.

Not sure what you mean - the seeders (for mainnet) are working fine, and are in the code: https://github.com/namecoin/namecoin-core/blob/69e327b36b89c64059ad529ea9867fd1577dbf35/src/chainparams.cpp#L156

For testnet, we do have a seeder in the code as well, but it seems to not be working. I cannot fix that, as I'm not the one running it. But if you or anyone else is willing to run a testnet seeder, I'm happy to add it in the code as well.

Rav3nPL commented 5 years ago

@domob1812 sorry, I was sure that this testnet seed is yours :)

domob1812 commented 5 years ago

For those who come here in hopes of getting up a testnet node, I've also set up one now that can be used as addnode: 51.75.22.122

We really should set up a working seed for testnet, but I don't have any servers available for that myself at the moment.

This is my current addnode list for testnet:

addnode=testnet.namecoin.org addnode=31.45.121.24 addnode=45.33.65.68 addnode=51.68.251.200 addnode=38.133.141.29 addnode=51.75.22.122

domob1812 commented 5 years ago

FYI, the just released version 0.18.0 schedules a softfork (BIP16, CSV and segwit, see #239). On testnet, this will activate at block height 232,000, which is rather "soonish" (but it depends on mining activity, of course). So please everyone running testnet nodes update so that we can hopefully see all working well on testnet before the mainnet activation.

while I try addnode 51.75.22.122 it seems dose not work anyway, by the way ,my node at Hong Kong

I've checked the chaininfo after a night ,it synced up to 23097 blocks~~

blocked in 233225 for a long time

domob1812 commented 4 years ago

Interesting, my own testnet node as well. Perhaps some nodes have not updated for segwit and are thus producing an invalid (longer) chain? I've not looked into that, though, so this is just a vague guess.

yanmaani commented 3 years ago

Resolved? New testnet seed was added.
