Hello Jamie,
A second thought, is IPv6 enabled on your frontend? Have you tried
completely disabling it?
Because in /opt/xcat/Sbin/xcatd I read the following:
my @clients;
if ($inet6support) {
@clients = gethostbyaddr($conn->peeraddr,AF_INET6);
} else {
@clients = gethostbyaddr($conn->peeraddr,AF_INET);
}
my $validclient=0;
my $node;
foreach my $client (@clients) {
$client =~ s/\..*//;
($node) = noderange($client); #ensure this is coming from a
node IP at least
if ($node) { #Means the source isn't a valid deal...
$validclient=1;
last;
}
}
unless ($validclient) {
close($conn);
next;
}
my $tftpdir = xCAT::Utils->getTftpDir();
eval {
alarm(2);
print $conn "ready\n";
Will look into this as soon as I can to confirm my idea: will disable
(if enabled) IPv6 on the frontend and the will also try to alter the
xcatd to avoid that AF_INET6 lookup.
Ciao,
Dario
