hi i have some problems with the new framework of security of amanda

my server and my client is in the version 2.5.1p2

the amanda-client.conf on the client is this one

conf "int" # your config name
index_server "backup" # your amindexd server
tape_server "backup" # your amidxtaped server
#tapedev "" # your tape device
# auth - authentication scheme to use between server and client.
# Valid values are "bsd", "bsdudp", "bsdtcp" and "ssh".
# Default: [auth "bsdtcp"]
auth "bsdtcp"

when i run amrecover i got these results

amrecover -s backup
AMRECOVER Version 2.5.1p2. Contacting server on backup ...
[request failed: Connection refused]

on the server the debug file
amindexd.20070123151619.debug

amindexd: version 2.5.1p2
close debug file: Bad file descriptor

does someone knows how to solve the problem?
