Re: Unable to resolve DNS host

If your backup client hostname is not resolvable via DNS then you will need to add a hosts file entry (on the Master Server and also on any Media Servers) for the backup client, and then issue the command:   bpclntcmd -clear_host_cache    on Master Server and all Media Servers.

Unfortunately we know nothing at all about your environment, so I think it might be best if you start here:

Resolving network communication problems with UNIX clients

...and posisbly other sections of the NetBackup Troubleshooting Guide.

Gosh.  I've only had a quick scroll through, but IMO I cannot see anything specifically Unix about the content at that particular link, and so, IMO I would think that the steps will also be appropriate for Linux.
