 Posted: Sun May 09, 2010 7:09 pm Post subject: ssh over ipv6? |
 |
|
Somewhat naively I thought I could just ssh to IPv6 adresses just like IPv4.
Why does
ssh IPv6
yield
"Network is unreachable"?
Ifconfig shows I have a IPv6 adress myself, and I think I have the necessary support:
| Code: | ~ # zcat /proc/config.gz | grep IPV6
CONFIG_IPV6=y
# CONFIG_IPV6_PRIVACY is not set
# CONFIG_IPV6_ROUTER_PREF is not set
# CONFIG_IPV6_OPTIMISTIC_DAD is not set
# CONFIG_IPV6_MIP6 is not set
CONFIG_IPV6_SIT=y
# CONFIG_IPV6_SIT_6RD is not set
CONFIG_IPV6_NDISC_NODETYPE=y
# CONFIG_IPV6_TUNNEL is not set
# CONFIG_IPV6_MULTIPLE_TABLES is not set
# CONFIG_IPV6_MROUTE is not set
# CONFIG_NF_CONNTRACK_IPV6 is not set |

I've never used ipv6 myself, but 'network unreachable' probably means here you're missing a default gateway. Could you show us your network configuration as well as what you're trying to do?

And right you are. Turns out my ISP doesn't support IPv6 at all because "we have enough IPv4 adress-space, and see no economic motive for IPv6".
I just checked that eth0 had a "inet6 addr", and it does, so I thought I was ready to go.
What I am really looking to do is to make my webservers visible in IPv6-space, this makes it more complicated to verify that I get it right. |

If you system has support for IPv6, the you probably have a "local" IPv6 address, attached to your nic,
as in you did not get it from the DHCP-server so you system gave you one .... (the same goes for IPv4)
It does not have to be very complicated at all actually.
Go get your self a ipv6 tunnel at www.tunnelbroker.net
It's free and pretty easy to set up.
