DNS Port 53 question


#1

Good day

Is there a way for activating the product without contacting the DNS Server port 53?

Thank you

Hello

That depends on whether it’s a physical or a virtual EH appliance.

For the physicals yes but for the virtuals it’s a no.

The EH licensing verification is done via DNS queries / responses so the EH virtual appliance needs to be able to query d.extrahop.com where it will check it’s license via querying a number of TXT records, if it can then the licensing will fail and the virtual EH appliance will stop capturing new data.

If you cannot allow this to happen then a possibility would be to use the ECM for this but then the ECM would need DNS access to d.extrahop.com so it can do the license verification on behalf of the virtual EH appliance.

Does this makes sense?
