How to – use one dynamic portal for whitelisting and have it sync across an entire cluster<\/h1>\n\n\n\n

This article will go over a method I have recently come up with in order to have your agents sign in through one dynamic portal<\/a> and have their IP validated across all servers in the cluster.<\/p>\n\n\n\n

Step 1 – Generate a SSH key<\/h2>\n\n\n\n

In your linux cli simply type “ssh-keygen” and just press enter for all default values with no password as shown below<\/p>\n\n\n\n

\"ssh-keygen\"

Step 2 – copy the ssh key to the other servers you need it synced to<\/h2>\n\n\n\n

ssh-copy-id -i ~\/.ssh\/id_rsa.pub 192.168.80.121 (replace IP with the servers Ip’s as you do each one)<\/p>\n\n\n\n

Type yes and then enter the servers root password, do these steps for each server in your cluster<\/p>\n\n\n\n

Step 3 – rsync the Dynamic IP firewall list to the other servers<\/h2>\n\n\n\n

Replace the IP’s with each one in your cluster and repeat this step for each<\/p>\n\n\n\n
