Happy new year 2011!

Happy new year 2011 to everybody ! and to start this new year, here is a small IPv6 tips to discover all IPv6 machines in a network :

# ping6 ff02::1%eth0

or

# ping6 -I eth0 ff02::1

according to the ping6 version.

This will return IPv6 addresses of all machines connected on the said interfaces. For instance :

64 bytes from fe80::4261:86ff:fe00:5a6: icmp_seq=1 ttl=64 time=0.016 ms

In order to connect to it with ssh, it’s all easy :

$ ssh root@fe80::4261:86ff:fe00:5a6%eth0
