I took another look at your smb.conf for the non working machine and
saw that I missed something.

You might want to read the section on 'hosts allow' in 'man
smb.conf'.

This parameter expects either a name or IP and defaults to 'hosts allow
=' , that is nothing after the '=' and this means that no hosts are
denied access. Do do you have a computer called 'ALL', because that is
the only computer that will be allowed access.

Thanks - I changed "hosts allow = ALL" into "hosts allow =
192.168.0.0/255.255.255.0" and restart
smb service.

But as before:
root at fileserver:~# smbclient -L athlux
lpcfg_do_global_parameter: WARNING: The "encrypt passwords" option is
deprecated
lpcfg_do_global_parameter: WARNING: The "domain logons" option is
deprecated
protocol negotiation failed: NT_STATUS_CONNECTION_RESET

I don't believe it is the samba configuration because I have a similar issue
with NFS.
"showmount -e athlux" on athlux lists the NFS shares
"showmount -e athlux" on fileserver returns "clnt_create: RPC:
Unable to receive"
athlux can can mount both, nfs-shares as well as samba-shares from athlux and
from fileserver.
But fileserver can't mount anything from athlux

I can ssh into both machines as I like. So network configuration must be ok.
"iptables -F" disables
my firewall.
Maybe there is an service, used by both, samba as well as nfs but not from ssh.
This service could
be broken?
