Kind of.
No zeroconf. For some reason. But at least ipv6 local-scope.
Used wireshark to capture dhcp probes to get MAC address.
Converted MAC address into IPv6 local scope address.
ssh ipv6%interface
and I am in!
Now to later do this later to the actual box rather than between two
notebooks. But it should work the same!

I have a headless system that I cannot connect to. So I was thinking
to put a direct connection to it and my notebook. Both ethernets
would use the zeroconf (169.254.0.0/16) addresses. I could then use
fping
fping -g 169.254.0.0/16
And SHOULD be able to get its address, and then SSH into the box.
I was under the impression that zeroconf did some rudimentary name
resolution, and you ought to be able to connect to hostname.local
(replacing "hostname" with the actual hostname).
It'd be a bit dopey if a zero-configuration scheme required you to
configure things...
I am doing a little testing, and zeroconf does not seem to be
working. I am seeing the link up light on my ethernet port. I am
seeing a local-scope v6 address, but no v4 address:
p6p1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::ea9a:8fff:fe8d:7b56 prefixlen 64 scopeid 0x20<link>
ether e8:9a:8f:8d:7b:56 txqueuelen 1000 (Ethernet)
RX packets 7 bytes 2130 (2.0 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 46 bytes 4948 (4.8 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Note that it is receiving packets from the other system. It also has
a local-scope ipv6 addr, but no zeroconf addr (both systems are Fedora
20).
So how do I start zeroconf? Of course on the other system, I can't do
that...
So given ipv6 local-scope, how do I learn the other system's addr.
Trying to figure out fping6. How do I restrict it to the desired
interface?
Any other thoughts? I can't get to the box to recable it and reboot
it (as that is the only way I can figure out for it to readdress eth0)
until this evening.
Only that: Are you on the same network? 169.254 connections can't be
expected to be reachable outside of their own net.
Crossover cable. Is that enough of a 'same network'? :)
And I have considerable routing and addressing knowledge. Besides
being one of the authors of rfc 1918, and worked on CIDR, here at IETF
I contribute to ipv6ops and ipv6man.
