My /etc/hosts file looks like this;
======================================================================
::1                     localhost.adhost.com localhost
127.0.0.1               localhost.adhost.com localhost
10.211.1.105            bak-05.adhost.com bak-05
10.211.1.105            bak-05.adhost.com.

So why is amanda unable to resolve "localhost"?

TIA.
