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`:
```
lncli -n testnet getinfo

#### 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 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.
```
$ lnd --listen=0.0.0.0:9736
```
We can check it's listening on 9736 port using this command:
```
$ netstat -aon | grep 9736
tcp6 0 0 :::9736 :::* LISTEN off (0.00/0/0)
$
```
Now we can use `lightning-cli connect` command to reach node as a peer:
```
$ lightning-cli --network=testnet connect 0302d48972ba7eef8b40696102ad114090fd4c146e381f18c7932a2a1d73566f84@127.0.0.1:9736
{
"id": "0302d48972ba7eef8b40696102ad114090fd4c146e381f18c7932a2a1d73566f84",
"features": "02a2a1"
}
```
To check out:
```
$ lightning-cli --network=testnet listpeers
{
"peers": [
{
"id": "0302d48972ba7eef8b40696102ad114090fd4c146e381f18c7932a2a1d73566f84",
"connected": true,
"netaddr": [
"127.0.0.1:9736"
],
"features": "02a2a1",
"channels": []
}
]
}
```
On success, an object with a “peers” key is returned containing a list distinct objects. Object features are bit flags showing supported features (BOLT #9).
