"selfcheck request timed out" problem !!

Hi,
I have this problem that's getting me mad!

Amanda used to work very fine between the backup server (gentoo/ Amanda installed through "emerge amanda"), and my personal pc (ubuntu/ Amanda installed through "apt-get install amanda-client").
Now we have moved the backup server to a different network zone and now the Amanda client is installed on a server on the same zone (no firewall). The client has gentoo installed, and since there's no amanda-client in gentoo portage amanda is installed (client with server) "emerge amanda" < I'm not sure if this can cause problems >.

The situation right know is as the following:

The backup server:
---------------------
$ hostname -f
backup.xxxx.com

/etc/amanda/amandahosts:
auth02.xxxx.com root

/etc/amanda/daily/disklist:
auth02 /etc comp-user-tar

/etc/xinetd.d/amanda:
service amanda
{
        disable         = no
        socket_type     = stream
        protocol        = tcp
        wait            = no
        user            = amanda
        group           = amanda
        groups          = yes
        server          = /usr/local/libexec/amandad
        server_args     = -auth=bsdtcp amdump amindexd amidxtaped
}

cat /etc/services | grep amanda
amanda          10080/tcp                       # amanda backup services
amanda          10080/udp
kamanda         10081/tcp                       # amanda backup services (Kerberos)
kamanda         10081/udp
amandaidx       10082/tcp                       # amanda backup services
amidxtape       10083/tcp                       # amanda backup services

The client:
------------

hostname -f
auth02.xxxx.com

/etc/amanda/amandahosts:
backup.xxxx.com amanda

/etc/xinetd.d/amanda:

service amanda
{
        socket_type     = dgram
        protocol        = udp
        wait            = yes
        user            = amanda
        group           = amanda
        groups          = yes
        server          = /usr/libexec/amandad
        server_args     = -auth=bsd amdump amindexd amidxtaped
        disable         = no
}

cat /etc/services | grep amanda
amanda          10080/tcp                 # amanda backup services
amanda          10080/udp
kamanda         10081/tcp                 # amanda backup services (Kerberos)
kamanda         10081/udp
amandaidx       10082/tcp                 # amanda backup services
amidxtape       10083/tcp                 # amanda backup services

Now when:
backup ~ # su - amanda -c "/usr/sbin/amcheck daily":

WARNING: auth02.xxxx.com: selfcheck request timed out. Host down?
Client check: 1 host checked in 29.999 seconds, 1 problem found

What do you suggest? I tried a lot but couldn't get it to work, is there something missing on the client? Something wrong? Is it a problem with amanda service? Maybe a permissions problem?

Thanks in advance
