don't get it.. blocks?   the relay always sends me transactions after i've already received them, so it's essentially wasting bandwidth
Your Gangnam-nodes are also a relay-network Smiley

Oh, yah, I realized that.  I figured turning it off would save some bandwidth, at least.  Everything is running with the updated code now, though I still wish there was a way to set it to blocks only.. don't need transactions relayed to any of my nodes, really.
THat would entirely defeat the purpose...you cant compress without pre-relaying.

This seems to be relaying massive amounts of dust transactions, I had over 25000 stored.

Had to turn it off.  Now debug.log is getting spammed with

and a good 50% or more of my peers are sending me an inordinate amount of data

This is not specific to the relay network, this was just someone flooding the Bitcoin network with lots of transactions. The relay network, at least, will no longer do this.

can't be stopped, unless I go through and start firewalling every single one of those nodes.  That's on one of my 100mbit connections too, which is why it only has 100 connections.  I've seen 50MB/s receive amts on 1Gbit

ed:   someone with several thousand $'s to waste could easily get some 10Gbit dedicated lines, and just flood everyone out with trash transactions.

ed2: and i suppose I should point out that this would be different from a typical DoS attack in that they'd have hundreds, or a thousand or two or three helpers, all transmitting as many of those transactions as their bandwidth could handle (turning it into a DDoS, with the quickness!)...   ed3 (last one I hope, wtf):  I've considered upping the minimum version level of connections...  that would get rid of 99%, just the 1% malicious would remain

lol, is your libc REALLY broken??? I'm really not sure how thats possible...is this reproduceable?

 Cheesy I'm buggered if I know - it only happened the once too, so not reproducible I'm afraid.

Can you try with connections to the relay network blocked (I'm assuming this happened when you couldn't connect to any servers)?

I still get a warning when compiling the latest version, but it does run now. I'm still getting plenty of this:

Code:
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)
Its having trouble connecting to your local bitcoind it looks like? Anything in your debug.log?

Thanks for adding the extra info to the web page Matt. I'm sure the attack situation must be wrecking your head somewhat, especially with noobs like me constantly asking silly questions!  Cheesy  Your work is very much appreciated, & I for one will be throwing a tip or two your way as & when I can - thanks again  Smiley

Seems I'm back to only sending (on west) and rarely getting txns back.
The rare Received ones are always just after, and the same size as, so most likely the same transactions as, the non "(out-of-band)" that it says I send.
This is largely expected. When you're sending out-of-band it means you're running an unmodified bitcoind (more on that later). The send/receive is the same as before, you're echoing the server's sent txn (the printing of what is happenning is out of order, I fixed that now). However, the server is now sending transactions less often (only when its view of what the next few blocks should be changes, instead of on each new transaction).

What are these?

Code:
Sent transaction of size 226 (out-of-band) to relay server

out-of-band transactions are transactions sent but not assumed to be in the next block (ie they will not be compressed if they do appear in the next block). More to come on the website soon.

Oh, and I added a donation address to cover the 45USD/month I'm currently shelling out for the servers :p (1NRuqMJAzUGwvFigukLa3UZqcJXix1dETM, feel free to check that address' balance and only donate if the server costs havent already been covered, though if its usually over I'll invest in more servers)
Just updated my main node from the Jul-4 version to now.

All running OK now.

The Jul-4 version regularly disconnects/reconnects and doesn't send block notifications to bitcoind because of that ... so I'd guess update it is necessary.

Sorry for the lack of replies, I've been heads-down rewriting the way transactions are handled to work in cases where mempools are reasonably large. That seems to be working now (though much tweaking remains to be done to make it perform well). There is also a new node in Tokyo (you may want to restart your client to auto-detect if its closer for you, or if you had already been connecting to the jpy hostname, you should already be using it).

I'm gonna try to be better at keeping an updated news section in on http://bitcoinrelaynetwork.org, so keep an eye there as things get updated. There will be new operating instructions due to the changes (though if you ignore them things will still work, and probably just as effeciently unless you're using strange transaction policy).

edit: I fixed it by disabling it attempting to build that file since it's not even included in my binary. Probably shouldn't build all the assembly files unconditionally.
I did this on master now.

He changed the parameter order ...

You now should just:
./relaynetworkclient 127.0.0.1 8333

You can specify which server to use on the end, but it will automatically choose one if you don't, by running a ping test to find the closest.

Edit: note the relay isn't responding at the moment at all ...

Hmm seems like the relay is pretty much overloaded and not doing it's job at all today.
One of my nodes is permanently sending tnxs to it, getting disconnected every few minutes, and never getting any blocks from it.
Oh well.
Isn't the relay network just for blocks? If not why isn't it?
Because a block needs all the transactions it contains to be able to verify it.
So the relay client has all those transactions, so when a block shows up it can send the block and all the transaction required to the bitcoind ... which is a local network transfer and thus VERY fast.
But it seems like receiving all tx from all nodes is to much for the relay servers to handle. I don't get why not simply focus on blocks. No one cares if a tx needs a few seconds extra till it gets to the miner (tx relay only through p2p network). Since the relay server doesn't verify the tx in a block there is no advantage in pre verifing the tx (signature cache).
When the relay servers receive a new block it cointains all tx. Or does the server only receives the block header an all tx hashes?

Hmm seems like the relay is pretty much overloaded and not doing it's job at all today.
One of my nodes is permanently sending tnxs to it, getting disconnected every few minutes, and never getting any blocks from it.
Oh well.
Isn't the relay network just for blocks? If not why isn't it?
