Error code 48
Dear All, I add new unix client on the NBU console, and test the backup, but the client hostname could not be found (48), then I already add the host name on the media server, master server, run th...
Have you validated full forward and reverse resolution from the client, too? My guess is you're having an issue at the client, not the Master, but also double/triple check the hostname as it appears in the UI. I've fat-fingered many client names in the console and gotten it right when troubleshooting, and spent many hours banging my head against that simple wall.
Also, are you using long or short name? I have seen issues in environmental DNS where some DNS servers return a different result based on long or short name when one server in the environment doesn't respond correctly. Might be a long shot, but doing a dig on each name server the Master is configured is a good troubleshooting step.
I 'm follow the existing NBU Client as the example for the client fqdn hostname.
I'd go back to the very beginning to troubleshoot this.
Start with the operating system. Can the Master ping short and long name of the client? Can the Media ping short and long name of the client? Can the client ping short and long name of both Master and Media?
Can Master, Media and Client all resolve the reverse DNS of each other?
Can the Master ping short and long name of the client? yes it can
Can the Media ping short and long name of the client? yes it can
Can the client ping short and long name of both Master and Media? yes it can
And reverse lookup with the IP address of the client?
