It seems, that my backup node tells the primary to shutdown the services for an
take-over; But the primary node reactivates himself and sends arp broadcast!

Any suggestions why my backup wants to takeover and the primary don't give
control away!? This effect is written in the troubleshooting FAQ, but there is
no hint to get it work.

Alternatively you can tweak your hosts.allow, and you hosts file to allow
access.
make sure that the relevant machines in the cluster have local IP entries
in you /etc/hosts file, and are allowed in /etc/hosts.allow
The problem that I had was the inability to resolve host names for machines
within a NAT cluster because of their local only IP address. The minute
timeout is a "typical" name lookup timeout.
I don't know if this is entirely relevant.... I lost the previous setup
description e-mails. But I do know that disabling tcp wrappers is not
necessarily the right solution as it will disable logging and allowed IP
security checks. I have a NAT cluster running FTP and telnet and ssh, all
tcp wrappered with no access delays / problems.
