 |
|
Im having problems with radvd, I simply cant use Ipv6 on my Windows2000 box inside the LAN thru the gentoo router. I compiled these Networking options into my kernel (2.4.20 vanilla source):
| Quote: | # Networking options
#
CONFIG_PACKET=y
# CONFIG_PACKET_MMAP is not set
CONFIG_NETLINK_DEV=y
CONFIG_NETFILTER=y
# CONFIG_NETFILTER_DEBUG is not set
# CONFIG_FILTER is not set
CONFIG_UNIX=y
CONFIG_INET=y
CONFIG_IP_MULTICAST=y
# CONFIG_IP_ADVANCED_ROUTER is not set
# CONFIG_IP_PNP is not set
# CONFIG_NET_IPIP is not set
# CONFIG_NET_IPGRE is not set
# CONFIG_IP_MROUTE is not set
# CONFIG_ARPD is not set
# CONFIG_INET_ECN is not set
# CONFIG_SYN_COOKIES is not set
# IP: Netfilter Configuration
All "yes"
# IPv6: Netfilter Configuration
All "yes"
|
I emerged radvd 0.7.2 and configured it like this :
| Quote: | interface eth1
{
AdvSendAdvert on;
prefix 2001:08e0:abcd:17e::/64
{
AdvOnLink on;
AdvAutonomous on;
};
};
|
I got 2 eth cards, eth0 is for internet (cable modem attached) , eth1 is internal LAN. Ipv6 configuration is set by following :
| Quote: | LOCAL4=194.249.35.3
REMOTE4=212.25.25.23
LOCAL6=2001:08e0:abcd::5fa/126
REMOTE6=2001:08e0:abcd::5f9
ip tunnel add tunnelbroker mode sit local ${LOCAL4} remote ${REMOTE4}
ip link set dev tunnelbroker up
ip link set mtu 1280 dev tunnelbroker
ip tunnel change tunnelbroker ttl 64
ip -6 addr add ${LOCAL6} dev tunnelbroker
ip -6 route add 2000::/3 via ${REMOTE6} dev tunnelbroker
ifconfig eth0 inet6 add 2001:08e0:abcd:17e::1/128
|
Ipv6 forwarding is enabled in /etc/sysctl.conf :
net.ipv6.conf.all.forwarding = 1
Now, when I start radvd, it runs normally, radvdump gives me this info :
| Quote: | Router advertisement from fe80::e0:4cff:fedd:3358 (hoplimit 255)
Received by interface eth1
# Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump
AdvCurHopLimit: 64
AdvManagedFlag: off
AdvOtherConfigFlag: off
AdvHomeAgentFlag: off
AdvReachableTime: 0
AdvRetransTimer: 0
Prefix 2001:8e0:abcd:17e::/64
AdvValidLifetime: 2592000

AdvOnLink: on
AdvAutonomous: on
AdvRouterAddr: off

My Win2k box has MS Ipv6 stack installed, I downloaded it from www.hs247.com (Sp3 Fix). When I run "ipv6 if" it lists my devices as following (I'll skip the Tunnel Pseudo-Interface and Loopback Pseudo-Interface) :
| Quote: | C:\>ipv6 if
Interface 4 (site 1): Local Area Connection
uses Neighbor Discovery
link-level address: 00-50-bf-7a-54-39

As you can see, the Interface 4 has "uses Neighbor Discovery" option and has already a Ipv6 ip using my prefix (preferred address 2001:8e0:abcd:17e:250:bfff:fe7a:5439), as i marked that with bold.
The problem is when i try to ping6 from the win2k box, it wont work:
| Quote: | C:\>ping6 www.kame.net
Pinging apple.kame.net [2001:200:0:4819:210:f3ff:fe03:4d0] with 32 bytes of data
:
Request timed out.
|
If i check the /var/log/syslog i can see a error msg that repeats from time to time, starting when i run the ping6 from win2k :
Mar 9 17:15:47 linuxdog radvd[16829]: version 0.7.2 started
Mar 9 17:23:26 linuxdog kernel: ndisc_send_redirect: not a neighbour
Mar 9 17:25:35 linuxdog last message repeated 9 times
I have searched on google about this problem, but didnt found a solution for now ... I hope that someone here could help me .
Thanx in advance. |
