Now that we have funded our c-lightning wallet we will get information about remote node to start creating channel process. On LND nodes you can get information about your node using `lncli -n testnet getinfo`: Now that we have funded our c-lightning wallet we will get information about remote node to start creating channel process. Using `lightning-cli --network testnet listchannels` command you can list all active channels and select one remote node and it's public key:

#### Connect to remote node #### Connect to remote node
The first thing you need to do is connect your node to a peer. This is done with the `lightning-cli connect` command. Remember that if you want more information on this command, you should type `lightning-cli help connect`. The connect RPC command establishes a new connection with another node in the Lightning Network. The first thing you need to do is connect your node to a peer. This is done with the `lightning-cli connect` command. Remember that if you want more information on this command, you should type `lightning-cli help connect`. The connect RPC command establishes a new connection with another node in the Lightning Network.
To connect your node to a remote peer you need it's id that represents the target node’s public key. As a convenience, id may be of the form id@host or id@host:port. In this case, the port parameter must be changed due we're running two nodes on the same machine, c-lightning node it's running on 9735 default port and we've started LND node on 9736 port with this parameter. To connect your node to a remote peer you need it's id that represents the target node’s public key. As a convenience, id may be of the form id@host or id@host:port. Using `lightning-cli help listnodes` command you obtain all nodes available on the network and choose one.
``` ```
lnd$ lnd --listen=0.0.0.0:9736 c$ lightning-cli help listnodes
``` ```
We can check it's listening on 9736 port using this command: Output
``` ```
c$ netstat -aon | grep 9736 {

Now we can use `lightning-cli connect` command to reach node as a peer: We've selected node with public key 0302d48972ba7eef8b40696102ad114090fd4c146e381f18c7932a2a1d73566f84 and we'll connect as a peer with `lightning-cli connect` command:
``` ```
