# Using a remote node

In order to interrogate a node with cardano-cli and submit transactions to it with cardano-cli, cardano-cli needs to connect to its socket file. 

It is possible to use `socat` to connect to the socket of a remote node. For that, 2 things must be done:

* on the server running the node, where the socket file is, the following `socat` command must be executed:\
  `socat TCP-LISTEN:2010,reuseaddr,fork UNIX-connect:/opt/cardano/cnode/db/node.socket`\
  This command will create a TCP socket on the port 2010 (the port can be any available port), and will connect it to the cardano-node socket file (the path `/opt/cardano/cnode/db/node.socket` must be adjusted to point to the existing socket file).
* on the client, where the `cardano-cli` commands will be executed, the following command must executed:\
  `socat UNIX-LISTEN:/run/cardano-node.socket,fork,reuseaddr,unlink-early,user=<username>,group=<group>,mode=755 TCP:<server_ip_address>:2010`\
  The `/run/cardano-node.socket` is where the local socket file will be created. The \<username> and \<group> must be replaced with the username and the group of the user who will run the cardano-cli commands, the `<server_ip_address>` the must be the server's ip address or hostname, and the port 2010 must be the same port configured on the server.&#x20;

After doing this, the `CARDANO_NODE_SOCKET_PATH` environment variable must be set to the `/run/cardano-node.socket` file (the name that was used in the second command), and then cardano-cli can be used to interrogate the cardano-node.
