[LDM #ILT-461435]: No LDM access after hardware change

The error messages mean that the one machine can't reach the other
for some reason.  It could be that it can't translate the hostname
to an IP address, or that something (e.g., iptables) is not allowing 
packets through.  I suspect that the one system can't even ping(1)
the other.

Do you have a system or network administrator who could help?
