How to connect to a ZCC via SSH and perform connectivity troubleshooting steps
Viewed 1539 times
A Zerto administrator may require ZCC access to perform network troubleshooting between tenants and cloud sites. For this reason, we are providing an SSH key for customers to access the ZCC via SSH.
** Note: This KB applies to newly deployed ZCCs from Zerto version 7.0 and newer, and not existing ZCC that were installed prior to version 7.0.**
Starting from Zerto version 7.0, the Zerto Virtual Replication installation folder will contain a sub-folder called “Secrets”. Please note that only a user account with administrative access on the ZVM server can access this folder.
The "Secrets" folder will contain a file named "ssh.ppk" which can be loaded into PuTTY to securely connect to the ZCC via SSH as the "root" user (no password required).
To connect to the ZCC, follow these steps:
Once you have located the "ssh.ppk" in the "Secrets" folder, open PuTTY which is also located at the ZVR installation folder, and navigate to the "Auth" menu (Connection -> SSH -> Auth).
Click on the "Browse" button and load the SSH key file into PuTTY.
Navigate to the "Session" menu, enter the ZCC’s IP address in the "Host Name (or IP address)" bar, and click "Open".
Click Yes on the host’s SSH fingerprint alert
Use "root" as the username and press "Enter"
You should be now logged into the ZCC.
From the VRAs to the ZCC: First, use the following ZCC command to view the VRAs<-->ZCC port forwarding rules:
- Type: iptables-save > iptables.txt
- Type: less iptables.txt
Then, connect to at least one VRA (following the KB: "Connecting to a VRA via SSH") on the Cloud's site and one VRA on the Tenant's site and check the connection to the ZCC's cloud facing NIC and customer-facing NIC respectively via continuous ping and Telnet over the ports specified in the iptables.txt file for each VRA.
