Ipv6 configration error

[DeSync]

I am able to ping my gateway but when i try to ping a site like he.net i get the following error

[root@cosmo ~]# ping6 he.net
connect: Network is unreachable
[root@cosmo ~]#

Try changing the default route from using ::/0 to 2000::/3

[DeSync]

How would i do that sir?

How would i do that sir?

Assuming you are using Linux, it depends on which commands you used to bring up the tunnel, you'd change "::/0" to "2000::/3"

so

Code Select Expand

route -A inet6 add ::/0 dev sit1
becomes

Code Select Expand

route -A inet6 add 2000::/3 dev sit1

or

Code Select Expand

ip route add ::/0 dev he-ipv6
becomes

Code Select Expand

ip route add 2000::/3 dev he-ipv6

remember to delete the default route first before changing it.

what does he-ipv6 represent and i used this code for my route. if it helps so you know what i have to do and i am using linux.

Sorry if you think im stupid im just new :P

I used the linux-net-tool config on site and this is the lasst line in it
route -A inet6 add ::/0 dev sit1

How would i change that to whats the root delete command and add for new one.

Thanks!

use

Code Select Expand

route -A inet6 del ::/0 dev sit1
route -A inet6 add 2000::/3 dev sit1

Works! Thank you very much sir!

One more question. Now how would i go about adding ipv6 ips that i can use?

[DeSync]

My details are:

Routed /48: 2001:470:b8c7::/48 
Routed /64: 2001:470:1f0f:302::/64

Can you give me a example on centos how i would add a ipv6 ip

Thanks sir!

[broquea]

well with ifconfig

Code Select Expand

ifconfig eth0 inet6 2001:470:1f0f:302::1/64
ifconfig eth0 inet6 2001:470:1f0f:302::2/64

etc....

Also you'll have to edit any interface configuration files/scripts so that the machine automatically brings up interfaces with the IPv6 addresses, as well as the tunnel interface, when/if it reboots.

Lots of documentation on that for the various Linux distros via Google search.

For example on centos would this work

ip addr add 2001:470:b8c7::17 dev eth0

For example on centos would this work

ip addr add 2001:470:b8c7::17 dev eth0

ip addr add 2001:470:b8c7::17/64  dev eth0 (which assumes you are using the 2001:470:b8c7:0::/64 block out of your /48)

Ok now im trying to get my ipv6 ip DNS to where i can use it for irc.

I went to freedns.afraid.org and it asked for my ipv6 subnet i put 2001:0470:1f0f:302::/64

Now i am adding a record and it says 2001:0470:1f0f:302:blank hostname

Did i do something wrong and everytime i enter a record it says invalid i want to be able to reverse dns 2001:0470:1f0f:302::13 what would be the subnet and the record for me to be able to reverse dns 2001:0470:1f0f:302::13

I'm not really familiar with their service, so hopefully someone on the forums can point you in the right direction for using them.

[broquea]

Ok so I made an account out of boredom, and the problem is easy.

They want the 3 sets of zeroes before your 13, so in their form, put: 0:0:0:13 (or 0000:0000:0000:0013)

I am currently working on a dutch version to show how to configure it the native centos/fedora/redhat way and will then also publish an english version once I am done.
