Technical Tip: Remote shell functionality in on-premises environments was disrupted due to certificate expiration

To deploy the fix of replacing the expired Remote Shell certificate,  follow the steps below:

1. Deliver the 'RSHELL_CERT.tar' file, which can be provided by TAC upon request, to the THR machine.
2. Log in to the THR machine using SSH and extract the RSHELL_CERT.tar file:

tar xvf RSHELL_CERT.tar

3. Change directory to the 'remote_shell_cert ' folder:

cd remote_shell_cert

4. Execute the script for replacing the certificate in the 'remote shell' deployment:

bash replace_cert.sh

5. Wait for the output:

Patching Remoteshell secret...
secret/edr2-onprem-remoteshell-certs patched
Restarting Remoteshell deployment...
deployment.apps/edr2-onprem-remoteshell restarted
Successfully patched secret and restarted deployment.

6. Make sure that a new 'remoteshell' pod has been created using the command:

kubectl get pods -n edr2-onprem

7. Validate that the remote shell functionally to the collectors is available again.
