You are ready to setup your Node's wallet which will be done directly on our instance.
Log into your node
From your local system, log into your cloud instance's terminal as nodeadmin using your Apple terminal, Window's PuTTY, or your terminal application of choice.
Bring our Node up to date
sudo apt -y update && sudo apt -y upgrade
You will be prompted for your nodeadmin password.
Your screen will not react and your password will not show as you type.
[...] in the output command examples means that there is a bunch of output that has been redacted to eliminate confusion.
[sudo] password for nodeadmin:
Create Tessellation directory
Create a directory in your user's home directory to hold some
Let's remind ourselves what our Node's external IP address is (copy it for later).
curl -s https://ipv4.icanhazip.com/
It is NOT RECOMMENDED to use a p12 file that is already in use for other purposes. You should create a new clean p12.
If you still insist, and you have an existing .p12 file, you can
SFTP the file over to your Node.
Transfer existing P12
Place your existing
.p12 file in your

Do not use the same passphrases of existing Nodes on Constellation, or any other Nodes from other projects. This is dangerous and bad practice.
You need to store your
lose your p12 credentials, there is nothing that can be done.
Click here to get an explanation of passphrases verses passwords.
We now need to create our passphrase for our
.p12 wallet on our
Our passphrase should be at least
10 or more characters.
Do not use the same passphrase (or other details) in the example below 👇! But, you can use something similar to the example below 👇
Create environment variables
We need to create some environment variables that will be used during the lifetime of the node. We will create a bash script for this purpose, and give it the name cn-node. We will come back to this script to update it later on during our configuration process.
For ease of usage, we will use Linux Nano Editor for this process, if you are a more advanced user, you can use Vim, or any other editor of your choice.
sudo nano /usr/local/bin/cn-node
How to use the
nano text editor is out of scope of this document; however, you can read up on how to create, edit and save a document at this link: How to Use Nano, the Linux Command Line Text Editor
You will need:
external IP addressof your Node. (Marked down at the beginning steps above 👆)
- You will create a
namethat you would like to call your
- You will create a
passphraseyou came up with using requirements above 👆.
- You will create an
aliasthat you would like to use against your
.p12file and the life of your Node. Your alias is public facing.
The Key passphrase
CL_KEYPASS has been changed to
CL_PASSWORD, for the .p12 creation process.
Do not use the same passphrase, alias, or p12 files name as in the examples here.
We have created our Node with the nodeadmin username. If you agreed and used the same, that is the only variable that should be kept the same as the examples below.
Environment variables chart
|Node Username||nodeadmin||If you used this |
|CL_EXTERNAL||126.96.36.199||Our Node's remote |
|CL_KEYSTORE||myconstellation.p12||This will be placed at the end of the path |
|CL_KEYALIAS||myConstellationAlias||Do not use this example, come up with your own.|
|CL_EXTERNAL||188.8.131.52||Our Node's (remote) |
MainNet 2.0 Dual Layer Requirements
|CL_L0_PEER_HTTP_HOST||IP address||This is recommended to be your Node's |
|CL_L0_PEER_ID||abcde...abcde||The Node ID of the Node you will be linking with on Layer0.|
|CL_L0_PEER_HTTP_PORT||9000||The public port of the Node you are linking to through Layer0.|
Create bash shell script
text file that will be saved as a bash shell script. When executed this will add some environment variables to your local environment where the script was run, these environment variables are ephemeral per user session.
This process may be deprecated in the near future; however, it is good to have in place for now.
You can use a text editor that comes standard with most flavors of Debian
Change directories to

cn-node file as super user (sudo)
Nano Quick Notes
sudo nano cn-cnodewill start the program
- use your keyboard arrows to navigate (not your mouse)
- ctrl-o command-o (letter o) will save the contents of the file
- give the file a name (
- ctrl-x command-x to exit the editor
Add the following to our
cn-node text file
When your file looks mostly similar to the above 👆. You will use Nano Quick Notes above 👆 to save the file out.
We want to make this file executable.
sudo chmod +x /usr/local/bin/cn-node
Run bash script
Run the bash script we just created by sourcing with the

In this example we are connecting to testnet
Let's check that the environment variables were added to our current shell environment. Your results may not be the in the same order, this doesn't matter.
env | grep CL_
Create a temporary env variable
We do not want to have our p12 passphrase added to a static plain text file. Our p12 file is our private key file that stores valuable information. If the passphrase is exposed, you can have access to the MainNet, State Channel, TestNet, etc. compromised, including access to wallets. This is a bad idea.
Instead, we will create a temporary environment variable prior to building our p12 file. The export we do below will only survive the current working session, and it will be lost after we log out.
Please be sure to follow the passphrase guidelines above 👆 and place your passphrase between the
Create your .P12 file
Change directories to our dedicated tessellation folder.
Generate your P12 private key
We will not use the
sudo command here. This will create our
p12 file with the ownership belonging to
java -jar /var/tessellation/cl-keytool.jar generate
Verify P12 file
Let's verify that we have a .p12 file.
DO NOT WORRY
The size and dates may not match, this doesn't matter.
The 2 l are the lower-case letter
L not the number 1 (ls -l)

Change the permissions of this file so only you can read and write to it.
chmod 600 ~/tessellation/myconstellation.p12

After a good amount of work and effort, we have our
