Access as localuser not allowed from remoteuser@remotehost
There must be something wrong with .amandahosts configuration (or .rhosts, if you have configured --without-amandahosts).
First, if the USERNAME is not what you expect (i.e., not what you have specified in the --with-user flag, at configure time), check the inetd configuration file: you must have specified the wrong username there.
Make sure you specify the names exactly as they appear in the error message after the `@' sign in .amandahosts/.rhosts. You'll need a fully-qualified domain name or not, depending on how your client resolves IP addresses to host names.
Check that the hostname in .amandahosts/.rhosts is the same as the one in the error message.
Check the ownership and permissions of .amandahosts/.rhosts. Adjust it:
chown amanda:disk ~amanda/.amandahosts chmod 0600 ~amanda/.amandahosts
Check .amandahosts/.rhosts for proper lines, usually you need two for each client, one for the amanda-user (for amdump) and one for root (for amrecover/amrestore):
amandaclient.my.domain amanda amandaclient.my.domain root
