Ok, I'm stuck here, getting still the same error when I do
oscar-config --bootstrap
...
====> in Database::update_table SQL: UPDATE Clusters SET

You can see he finds the headnode interface and the oscar_server correctly.
What is happening in
/usr/bin/set_node_nics
and what do I need the "surmised networks" for at this place?
The code that doesn't give the wanted results is:
# find out what we think the attached networks are based on
# the network interface settings for this machine
my %surmised_networks = ();
my $public_network_index = 1;
my $private_network_index = 1;
foreach my $nic_name ( keys %$ifconfig_nics_ref ) {
my $nic_ref = $$ifconfig_nics_ref{$nic_name};
# figure out a reasonable network name
my $network_name;
if ( exists $$nic_ref{rfc1918} && $$nic_ref{rfc1918} ) {
if ( $num_private > 1 ) {
$network_name = "private$private_network_index";
$private_network_index++;
} else {
$network_name = "private";
}
} else {
if ( $num_public > 1 ) {
$network_name = "public$public_network_index";
$public_network_index++;
} else {
$network_name = "public";
}
}
# set up the command to create this network
my %network = ( 'name' => $network_name,
'base_ip' => $$nic_ref{base_ip},
'high_ip' => $$nic_ref{high_ip},
'netmask' => $$nic_ref{netmask},
'rfc1918' => $$nic_ref{rfc1918} );
$network{ broadcast } = $$nic_ref{ broadcast }
if exists $$nic_ref{ broadcast };
$network{ gateway } = $$nic_ref{ gateway }
if exists $$nic_ref{ gateway };
$surmised_networks{ $network_name } = \%network;
}
if (keys(%surmised_networks) == 0) {
die "ERROR: Impossible to detect attached networks";
}
Can I just skip the an comment the line that gives the error?
Thanks for any hints,
Jan.

Ho, it seems that you're using a buggy oda package.
/usr/share/oscar/prereqs/oda/etc/mysql.cfg should point to
mariadb-server for centos- entry.
Thanks to you I4ve seen some typos errors in this file, so I'm
updating the package now. Should be available in less than 30 minutes.
Could you try doing:
yum update
and check that /usr/share/oscar/prereqs/oda/etc/mysql.cfg is now correct.
As for the othe issue, it's strange.
There is a know bug in the /etc/hosts update routing that put
oscar_server and nfs_oscar host aliases on all configured IPs (public
and private which is wrong. It should only put the alias for the
OSCAR_INTERFACE ip. (I need to correct this).
This file is updated more than once, so check that /etc/hosts has
oscar_server and nfs_oscar only set for one unique IP.
Aside that it should work eventhough the aliases are "bad" (underscore
char is not allowed for hostnames). I'll fix that in a later version.
feel free to add oscar-server and nfs-oscar and pbs-oscar (keeping
oscar_server, nfs_oscar and pbs_oscar for now)

What is going wrong?
Additional information:
Two NICs, one for the local, private cluster network which I used in
oscar.conf as OSCAR_NETWORK_INTERFACE.
Another NIC for communication with the internet.
Dowload of packages worked fine, the system seems to know what to use.
/etc/hosts:
