Refer to the following part of code in credentials.pm. You can get more
messages in the /var/log/messages on you xCAT MN. xCAT is trying to send the
file /etc/xcat/hostkeys/ssh_host_dsa_key to compute node. This file is
generated during install xCAT. Could verify this file is existed?
} elsif ($parm =~ /ssh_dsa_hostkey/) {
`logger -t xcat -p local4.info "credentials: sending $parm"` ;
if (-r "/etc/xcat/hostkeys/$client/ssh_host_dsa_key") {
$tfilename="/etc/xcat/hostkeys/$client/ssh_host_dsa_key";
} elsif (-r "/etc/xcat/hostkeys/ssh_host_dsa_key") {
$tfilename="/etc/xcat/hostkeys/ssh_host_dsa_key";
} else {
push @{$rsp->{'error'}},"Unable to read private DSA key from
/etc/xcat/hostkeys";
`logger -t xcat -p local4.info "credentials: Unable to read private
DSA key"` ;
next;
}
} elsif ($parm =~ /ssh_rsa_hostkey/) {
`logger -t xcat -p local4.info "credentials: sending $parm"` ;

} else {
push @{$rsp->{'error'}},"Unable to read private RSA key from
/etc/xcat/hostkeys";
`logger -t xcat -p local4.info "credentials: Unable to read private
RSA key"` ;
next;

}

Hallo,
i am very pleased with xCAT in general and only have a small problem, which i
could work around, but id rather it worked as intended.
I have a bunch of diskless nodes, which i manage and everything is working as i
wish apart from the host key transfer. the xcat.log on the nodes shows the
postscript "remoteshell" takes about 20 min to execute
and if i have a look at the log on the managing node i get this

which looks like the node cannot access the keys and after the 10 tries it
generates a new key.
This is very unfortunate and i am out of guesses, where this problem originates
from.
Could you give me a hint!?
