Further for your knowledge:
In the Internet Protocol Version 6 (IPv6), the address block fe80::/10 has been 
reserved for link-local unicast addressing. The actual link local addresses are 
assigned with the prefix fe80::/64 which is what you see on your wireless 
interface.
With this link local addresses you will not be about the reach your vps. You 
may need to look into Tunnel Broker services. Check out:

if  is not in your local network, you will either need
a tunnel or connectivity from your ISP to get IPv6. So this:

is indeed the problem.

Best,

Yes. 

You need to native IPv6 from your ISP, or an IPv6 tunnel from one of
the many brokers available on the net. 

Google for "ipv6 tunnel broker" if your ISP is not providing native
access.

Yes, you only have link-local connectivity, you either need to ask your ISP 
or set yourself up with a IPv6 tunnelbroker, I highly recommend the folks over
at HE (http://tunnelbroker.net/).

ssh user@ipv6 address, connect: Network is unreachable

2013-07-23 Thread basti 
Hello,

I have a vps host which has only an ipv6 address.
I try ssh user@ (or ssh -6 user@) but get
the following:

ssh: connect to host  port 22: Network is unreachable

ping6 google.com is the same

connect: Network is unreachable

my config:
