While setting up an ntp client/server, I found a weird error where the client cannot check it's own time.
I have traced this back to the fact that all of these commands time out:
ping localhost ping 127.0.0.1 ping 127.0.1.1 ping hostname ping 192.168.0.x
My hostname is set in /etc/hostname and is the same as my /etc/hosts file, which looks like this:
127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 127.0.1.1 hostname
I can't see any problems here.... The hostname is also unique for the network which is unmanaged and uses static IPs instead of dhcp.
