To run a multinode testnet, after starting a leader node, spin up some validator nodes:
```bash
$ ./multinode-demo/validator.sh ubuntu@10.0.1.51:~/solana #The leader machine
$ ./multinode-demo/validator.sh ubuntu@10.0.1.51:~/solana 10.0.1.51

As with the leader node, you can run a performance-enhanced validator fullnode by adding
`--features=cuda` to the line that runs `solana-fullnode` in `validator.sh`.

### Daemon support
The snap supports running a leader, validator or leader+drone node as a system
daemon.
Run `sudo snap get solana` to view the current daemon configuration, and
`sudo snap logs -f solana` to view the daemon logs.
Disable the daemon at any time by running:
```bash
$ sudo snap set solana mode=
```
Runtime configuration files for the daemon can be found in
`/var/snap/solana/current/config`.
#### Leader daemon
```bash
$ sudo snap set solana mode=leader
```
If CUDA is available:
```bash
$ sudo snap set solana mode=leader enable-cuda=1
```
`rsync` must be configured and running on the leader.
1. Ensure rsync is installed with `sudo apt-get -y install rsync`
2. Edit `/etc/rsyncd.conf` to include the following
```
[config]
path = /var/snap/solana/current/config
hosts allow = *
read only = true
```
3. Run `sudo systemctl enable rsync; sudo systemctl start rsync`
4. Test by running `rsync -Pzravv rsync://<ip-address-of-leader>/config
solana-config` from another machine. If the leader is running on a cloud
provider it may be necessary to configure the Firewall rules to permit ingress
to port tcp:873, tcp:9900 and the port range udp:8000-udp:10000
To run both the Leader and Drone:
```bash
$ sudo snap set solana mode=leader+drone
```
#### Validator daemon
```bash
$ sudo snap set solana mode=validator
```
If CUDA is available:
```bash
$ sudo snap set solana mode=validator enable-cuda=1
```
By default the validator will connect to **testnet.solana.com**, override
the leader IP address by running:
```bash
$ sudo snap set solana mode=validator leader-address=127.0.0.1 #<-- change IP address
```
It's assumed that the leader will be running `rsync` configured as described in
the previous **Leader daemon** section.
