How To:Configure rsh authentication
Dumptype definition changes
Apart for specifying auth field in dumptype definition, it might be required to specified client_username and amandad_path fields. If the backup user name is different on the Amanda client, the user name is specified as client_username. If the location of amandad binary is different on the Amanda client, the location is specified as amandad_path field value.
For example:
define dumptype rsh_example { ... auth "rsh" client_username "amandabackup" amandad_path "/usr/lib/exec/amandad" ... }
