- Generate a key pair in a Linux/macOS machine using the following command:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
As an example:
test@Test:~/.ssh$ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/test/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/test/.ssh/id_rsa
Your public key has been saved in /home/test/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:bKjBUsUGea7BeoZ3deK9ZLOvQTR250pxyydJxfBQFco your_email@example.com
The key's randomart image is:

-rw-r--r-- 1 test test 748 Mar 14 07:48 id_rsa.pub - View generated id_rsa.pub file and get the long key in the middle. As an example:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDLHcZJ4PWKs0hvZYYLkXUwbeV5LdKmlR7eZFpRDa/9AeNb36vGodL3Ezo+3wGQ6tlDCM2UoonfU+Fkk8MhrCTqbJc2DDkhjXUOD+5HrRdDbfQtMTv6V3lMMk7U2w== your_email@example.com
- Go to the Service Gateway terminal via admin account.
- Input "enable" command to go to privileged mode.
- Add public key generated into Service Gateway:
configure verify cli support "put_long_key_in_the_middle_here"
As an example:
configure verify cli support AAAAB3NzaC1yc2EAAAADAQABAAACAQDLHcZJ4PWKs0hvZYYLkXUwbeV5LdKmlR7eZFpRDa/9AeNb36vGodL3Ezo+3wGQ6tlDCM2UoonfU+Fkk8MhrCTqbJc2DDkhjXUOD+5HrRdDbfQtMTv6V3lMMk7U2w==
- From the original Linux/macOS machine, SSH to the Service Gateway using the following command:
ssh sgowner@ip_of_service_gateway -i /Users/username/.ssh/id_rsa
- After logging in to the Service Gateway backend with Service Gateway owner, switch user to root using the command:
sudo su -
