the kernel is built against. According to the manual below the order
keyword in your /etc/host.conf file may be deprecated. Try strace ping
node01 to see which system call drops an error.

It seems to be the result of some sort of timing/race issue with the
network manager. Immediately after boot (and for at least several hours
thereafter) ping doesn't work. However, if the ethernet cable is
unplugged long enough for the network manager to drop the interface,
like 20 seconds, then plugged back in again, suddenly ping by name
works.
