Hello,

Thanks for the suggestion. Unfortunately, that didn't fix it.

Hello,

I'm running a CentOS 5.6 server through linode. I am atempting to configure it for ipv6, previously this had been done though not by me on a ubuntu box so the hardware can take it. I've got an ipv6 tunnel through Hurricane Electric and at a shell prompt have done the following:

ifconfig sit0 up ifconfig sit0 inet6 tunnel ::IPV4 Address ifconfig sit1 up ifconfig sit1 inet6 add IPV6 Address route -A inet6 add ::/0 dev sit1

Testing that with a ping6 works fine. I then want it to persist across reboots. So I added the following to /etc/sysconfig/network:

NETWORKING_IPV6=yes       IPV6_DEFAULTDEV=sit1

and I made /etc/sysconfig/network-scripts/ifcfg-sit1

DEVICE=sit1       BOOTPROTO=none       ONBOOT=yes       IPV6INIT=yes       IPV6TUNNELIPV4=IPV4 Address       IPV6ADDR=IPV6 Address

Reboot the box, check sit1 and it has an ip address. Running that ping6 command says the network can't be reached. I have to take the interface down and rerun those above commands manually. I'd appreciate any suggestions.

Try adding TYPE=sit to /etc/sysconfig/network-scripts/ifcfg-sit1

Hello, Thank you for your response. The IPV4 endpoint address in ifcfg-sit1 is in fact the tunnel endpoint and not my system's address.

The output of ifconfig sit1 does in fact show the ipv6 addresses looks correct to me.

The output of ip -6 route | grep -v 'dev lo' shows ipv6 traffic going out sit1. I should probably mention I do not have any ipv6 firewall in place.

Thanks. Dave.

Looks good; I have the same.

   DEVICE=sit1
   BOOTPROTO=none
   ONBOOT=yes
   IPV6INIT=yes
   IPV6TUNNELIPV4=IPV4 Address

I have DEVICE=sit1 BOOTPROTO=none ONBOOT=yes IPV6INIT=yes IPV6TUNNELIPV4=remote_ipv4_address IPV6ADDR=my_ip6_address/netmask

Is the IPv4 address in the config above the IP address of the HE endpoint and _not_ your IP address? (In my case I have 72.52.104.74 for tserv3)

ifconfig sit1 should show something like sit1 Link encap:IPv6-in-IPv4 inet6 addr: your_ip6/metmask Scope:Global inet6 addr: fe80::link_addr/64 Scope:Link UP POINTOPOINT RUNNING NOARP MTU:1480 Metric:1 RX packets:756 errors:0 dropped:0 overruns:0 frame:0 TX packets:758 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:76421 (74.6 KiB) TX bytes:88155 (86.0 KiB)

Also check the output of ip -6 route | grep -v 'dev lo'
