Ipv6 Setup

11-03-2009, 18:58
I have tried setup up ipv6 on my system but am not getting too far - it seems to somehow resolve the dns request but the routing seems screwed. Anyone got any ideas?

The output of the kernel routing table is organized in the following columns

The destination network or destination host.

The gateway address or ‚*‚ if none set.

The netmask for the destination net; ‚‚ for a host destination and ‚‚ for the default route.

Flags Possible flags include
U (route is up)
H (target is a host)
G (use gateway)
R (reinstate route for dynamic routing)
D (dynamically installed by daemon or redirect)
M (modified from routing daemon or redirect)
A (installed by addrconf)
C (cache entry)
! (reject route)

Metric The ‚distance‚ to the target (usually counted in hops). It is not used by recent kernels, but may be needed by rout‚
ing daemons.

Ref Number of references to this route. (Not used in the Linux kernel.)

Use Count of lookups for the route. Depending on the use of -F and -C this will be either route cache misses (-F) or
hits (-C).

Iface Interface to which packets for this route will be sent.

MSS Default maximum segment size for TCP connections over this route.

Window Default window size for TCP connections over this route.

irtt Initial RTT (Round Trip Time). The kernel uses this to guess about the best TCP protocol parameters without waiting
on (possibly slow) answers.

HH (cached only)
The number of ARP entries and cached routes that refer to the hardware header cache for the cached route. This will
be -1 if a hardware address is not needed for the interface of the cached route (e.g. lo).

Arp (cached only)
