Client configured for auth=bsd while server requested 'bsdudp'

This article is a part of the Troubleshooting collection.

Problem

Authentication on the client and server does not match. The error message will display which authentication protocol is configured on server and the client.

Solution

• Authentication on the client and server should match for both backup (amdump(8)) as well recovery (amrecover(8)) process.
  • Fix the authentication value on in the xinetd configuration on the Amanda client; or
  • Fix the authentication field in the dumptype definition (in amanda.conf(8)) on the Amanda server

You can test a client's configuration from the server with amservice(8) in Amanda-2.6.1 or higher.

 amservice clienthostname auth noop </dev/null

where auth is the authentication you have configured on the client. If this displays a line beginning with "OPTIONS", then the client is configured correctly, and you should check your dumptype on the server. Otherwise, check the configuration on the client.
