piper:~|master|% ssh mother uname -a
Warning: Permanently added the RSA host key for IP address '2001:a60:f069:0:204:4bff:fe80:8003' to the list of known hosts.
Linux mother 2.6.18-6-k7 #1 SMP Fri Jun 6 22:56:53 UTC 2008 i686 GNU/Linux
This is weird, since I meticulously added the IPv6s of all my hosts
to the known hosts file:
piper:~|master|% grep 204:4bff:fe80:8003 .ssh/known_hosts

The problem is simply that I entered the shortened, RFC-compliant
version, which simply leaves out complete octet pairs of zeroes:
2001:a60:f069::204:4bff:fe80:8003
^v
vs. 2001:a60:f069:0:204:4bff:fe80:8003
OpenSSH's client seems to be unable to deal with this, which is
a bug, since the shortened version is defined in the standard.
