I'm at this part of the docs. The node is running (left terminal in the image below), but now I'm trying to query the blockchain from another terminal and receive the error:

cardano-cli: Network.Socket.connect: <socket: 11>: does not exist (No such file or directory)

my two ubuntu terminals

I'm running the cardano node on a windows laptop inside an ubuntu terminal that I downloaded from the windows store (as recommended in the cardano docs here):

windows store

I think that maybe the two Ubuntu terminals are completely independent from each other and that's why the right terminal can't find the socket? I tried to install the cardano node on a raspberry Pi 4 also, so that I have a native environment, but the raspberry was just to slow for it...

EDIT: I have set the socket path now like this at the bottom of my ~/.bashrc file:

enter image description here

then restarted the terminal, but still I receive the same error.

  • have you mentioned the socket location when starting the node?

  • I have set the same socket path as I used in the cardano-node run command: export CARDANO_NODE_SOCKET_PATH="~/cardano-src/cardano-node/db/node.socket" My cardano-node run command looks like this: cardano-node run --topology ~/cardano-src/cardano-node/config-files/testnet-topology.json --database-path ~/cardano-src/cardano-node/db --socket-path ~/cardano-src/cardano-node/db/node.socket --host-addr 127.0.0.1 --port 3001 --config ~/cardano-src/cardano-node/config-files/testnet-config.json and the query command: cardano-cli query tip --testnet-magic 1097911063

  • when I run echo $CARDANO_NODE_SOCKET_PATH in my terminal, it gives me the correct path back: ~/cardano-src/cardano-node/db/node.socket

  • But when I run ls -al $CARDANO_NODE_SOCKET_PATH I receive the error: ls: cannot access '~/cardano-src/cardano-node/db/node.socket': No such file or directory

I have found the solution for myself on a Coincashew tutorial. https://www.coincashew.com/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node#2-build-the-node-from-source-code

Basically i executed this:

echo export CARDANO_NODE_SOCKET_PATH="$NODE_HOME/db/socket" >> $HOME/.bashrc
source $HOME/.bashrc

That rewired the node path to socket (on the place of node.socket). Don't know what is the real difference but this way worked while the 'node.socket' path don't.

I was having this issue while trying to get the Plutus PAB to connect to the node. I tried lots of solutions but didn't get it to work until I changed the "testnet/node.sock" in the config (testnet/pab-config.yml). Perhaps it needed to be relative?

plutus-apps/plutus-pab/test-node/testnet/pab-config.yml

...
nodeServerConfig:
  pscSocketPath: testnet/node.sock

When you are specifying CARDANO_NODE_SOCKET_PATH in these formats:

"$NODE_HOME/db/socket" you must use double quotes around it

~/cardano/db/node.socket you don't need to give double quotes around it

Alright, the problem were the quotation marks. In the docs they use quotation marks too:

export CARDANO_NODE_SOCKET_PATH="/home/user/cardano/db/node.socket"

But here the guy didn't use quotation marks: https://forum.cardano.org/t/cardano-cli-network-socket-connect-socket-11-does-not-exist/38987/7

So I tried it without it in my ~/.bashrc file: enter image description here

and it worked after re-starting the cardano-node and the second terminal: enter image description here
