So your hostname should lookup to an address that contains a valid hostname for the client/server. All of our servers provide backups for two physically disparate networks. We manage this currently by creating entries in hosts files for servers that need backups (uggg...), though I want to move it all to DNS. If you ever get confused about what entries should exist, the easiest way to figure it out is to run amcheck and see what it complains about! Usually you'll get something descriptive like "10.0.0.2: No such host", and then you'll know you need to configure a name. > No second NIC, then what about additional IP addresses on the same NIC? > Those should be associated with their own hostnames also.

Virutal server host
Running Amanda 2.4.5p1 on a Solaris 10 Sparc. Has anyone tried to used a virtual host name for the backup server? This would be an easy way to move the amanda server to another host. All that would be required is that you add the server name as a virtual host name and you should be back in business. The problem that I see is that sometime the real name gets returned on certain request. Just wondering if someone has done it and if so was there something special that you had to do?
