This document describes the scenario where certificate on Video Communications Server (VCS) servers has been revoked and as a result the Graphical User Interface (GUI) is not accessible.
VCS with expired server certificate
In this scenario you would not have access to VCS GUI and an attempt to access the VCS through GUI will give you an error that the certificate of the VCS server has been revoked
To mitigate the issue you would need to revert to default certificates on the VCS. This will enable GUI access and then certificates will need to be re-generated.
You can achieve the above task in either of the two ways:
Use any SSH client and ssh to VCS using root credetials.
For versions prior to VCS 12.5(all 8.x versions), replace the existing certificates with the default certificates using the following commands:
~ # cp /tandberg/persistent/certs/server.pem.default /tandberg/persistent/certs/server.pem
~ # cp /tandberg/persistent/certs/privkey.pem.default /tandberg/persistent/certs/privkey.pem
~ # cp /tandberg/persistent/certs/ca.pem.default /tandberg/persistent/certs/ca.pem
~ # cp /tandberg/persistent/certs/client-ca.crl.default /tandberg/persistent/certs/client-ca.crl
~ # cp /tandberg/persistent/certs/policy-services.crl.default /tandberg/persistent/certs/policy-services.crl
~ # /etc/init.d/S80httpd restart
For version 12.5 the the defaults certificates dont exist anymore under:
~ # cd /tandberg/persistent/certs
~ # ls
You will not see the .default certs here.
You need to delete the server.pem and reboot the VCS which will revert the VCS to default certificates.
~ # rm server.pem
~ # reboot
