Title: Are there any solutions to identify relay-ip of  one tx like blockchain.info 

Often see on blockchain.info But cannot get through bitcoind

Thats the IP of the node that first informed blockchain.info about the transaction in question. The chance that its the node that created the transaction is very slim. In fact the node that broadcasts a transaction to the network for the first time might not belong to the person that created the transaction or own the private keys in question. E.g. I broadcasted a transaction for someone yesterday. That person had trouble accessing their wallet. Even if you would have caught the IP address for that transaction, it would have been my IP address and not the IP-address of the person that owns the bitcoins in question.

tl;dr: Its basically useless information.

bitcoind does not track or store this information as far as I know of.  I'm not sure why you would want to know which of your peers told you about a transaction, but if it is important to you for some reason, you'd have to modify your own copy of the program and rebuild the software to take note of and store the information for your own use.

Thanks. I just want to know the information about nodes connected.

Will this relay IP gives some location information of the person who created the transaction? Some users are using tor just to hide that IP, are they wasting their effort?

No.  It will only tell you which of your peers relayed the transaction to you.  It won't tell you who they got it from, or who created it.

That depends on what other steps they are taking to protect themselves.  TOR doesn't magically hide your IP if you make mistakes that leak your IP outside of TOR (or through TOR).

If they're using Tor just to hide their IP address, then yes, because that's not Tor is for. The IP address itself is irrelevant and doesn't prove anything. However, someone with full access to your network connection (your ISP, the NSA, etc) can see if you sent a transaction that you didn't already receive from another peer, which proves that transaction is yours and you're not relaying someone else's transaction. Tor protects against this, and this is the reason people (should) use Tor. IP addresses have nothing to do with it.

Thats not necessarily true. I could potentially create a signed transaction and send it to e.g. Danny via PM/(Snail)mail/SMS/OTR/DVBT/etc. for broadcasting. Or - even easier - broadcast it from a public WiFi at a remote coffee shop in my city. There are several miners and services that allow you to push a TX via their node.

If you just want information about the nodes your node is connected to you can use getpeerinfo it will include IP addresses.

Thanks. I just want to know the information about nodes connected.

Code:

bitcoin-cli getpeerinfo

wil tell you which nodes are connected to your node (including their ips).

Yes, relay ips are just peer ips.
