FAQ for ALICE

To install an ALICE node, what operating system do I need?  
The installation process is currently tested on Linux. Installing a node on other operating systems may be possible but not officially supported yet.
Can I install an ALICE node on my laptop/PC?
No. It is not possible because a node run on a laptop/PC are likely to have much more downtime than one run on a server.
Is it beneficial to run more than one node on ALICE?
Although It is technically possible to run numerous nodes on ALICE, it is NOT beneficial and NOT recommended. No matter how many nodes you run on ALICE, you will not be able to run more than one node in the Canary Network. That is because in the Canary network, a mechanism will be applied to verify the uniqueness of each node's operator.
Do I also need to run a Shield Server after joining ALICE? 
No. Joining ALICE has nothing to do with a Shield Server. A Shield Server is a complementary security measure run by dApps. To get more information about the Shield Server, see here.
How long do I need to operate my ALICE node to be eligible for the node-drop on Pioneer?
The date of node-drop distribution and the Pioneer launch have yet to be announced. The rewards from the ALICE network will be distributed based on the nodes' uptime, so operators should maintain their nodes throughout.
How can I back up my node? 
Refer to this section in the GitBook.
How can I transfer my node to a different server?
To do so, one should first back up the node. The backed-up config file should then be transferred to a new server and restore the node.​
Where can I find the <server-ip> to check if the node has successfully been added?
<server-ip> is actually the public IP of the server that you have used to connect to your server and installed the node on. And if the node is run locally, the <server-ip> is 127.0.0.1 .
What is the difference between the node’s address and the staking address?
The node address is the address that your node uses to sign requests with. It is automatically generated by the node and its private key is held in the config file of the node. 
The staking address, on the other hand, is the address of the owner of the node which is used to stake tokens when adding the node to the network. It is generated by the owner's wallet (for example MetaMask), and its private key is held inside the wallet.
Why are the rewards shown on the dashboard increasing in spite of the fact that my node is down?
A "Liveness Monitoring System" will soon be added to the network. When it is run, offline nodes do not collect rewards anymore. 
Can the rewards shown in the dashboard be actually used? Are the rewards related to the node-drop incentive in the Canary network? 
No. The node running rewards shown in the dashboard are just test tokens and have nothing to do with the node-drop incentive; that is, they carry no real value but help developers make sure the system is operating accordingly. 
When I check the status of my node on the dashboard, why do I see "Loading" or "Offline" ?
This means that your node is not reachable by the network. This might be because
The node has not yet been added to the network. If you open http://<server-ip>:8000/status , and addedToNetwork is false, this means your node is not yet added. If you have a backup file, follow the instructions HERE to restore your node. Otherwise, follow the instructions HERE to add the new node.
The node is down. You can use the docker ps -a command in your server to check if muon-node, redis and mongo containers are up and running on your server. If they are down, you can start them by running the docker-compose up -d inside the folder where the docker-compose.yml is placed.   
The node has been run on a local computer that does not have a public IP address. To solve the issue, you should backup the node and restore it on a vps.
The firewall of the server that the node is running on blocked ports 8000 or 4000. You can use services like portchecker.co to check if these ports are open on your server. You can usually open these ports using: 
sudo ufw allow 4000/tcp 
sudo ufw allow 8000/tcp
Some service providers also enable users to configure the firewall from the dashboard they provide.
If none of the above seems to be your problem, you can join Muon Discord and be in touch with the tech team in the #dev-help channel.
I see the error TSError: ⨯ Unable to compile TypeScript in my node logs. How do I resolve it?
If the status of your node in the dashboard is OFF and when you run docker logs -f --tail 50 muon-nodeyou see the following error,
TSError: ⨯ Unable to compile TypeScript:
error TS2307: Cannot find module 'ipfs-core-types/src/utils' or its corresponding type declarations.
 You need to run the following commands in muon-node-js folder line by line in order to 
back up your node,
docker cp muon-node:/usr/src/muon-node-js/.env ./backup.env
and rebuild it,
docker-compose down --rmi all
git pull
docker-compose pull
docker-compose up -d
and finally restore it.
docker cp backup.env muon-node:/usr/src/muon-node-js/backup.env
docker exec -it muon-node ./node_modules/.bin/ts-node ./src/cmd keys restore backup.env
docker restart muon-node
If you encounter an error when running any of these commands, you should resolve it before moving to the next one. 
I encounter this error: 'compose' is not a docker command. How can I resolve it?
This shows your docker is old. To solve this, you need to follow the instruction in install docker engine to install the latest version based on your server's operating system.
How can I remove the node?
NB: Make sure to backup your node before removing it if you are about to transfer it to a different server or install the latest version.
The following commands can be used to remove the Muon node's docker containers and images:
docker stop muon-node redis mongo 
docker rm muon-node redis mongo 
docker image prune
 If you installed the node by cloning the muon-node-js repository, you can also remove the folder by: 
rm muon-node-js -rf
