Hello folks,
I'm trying to setup an IPv6 address on my server, it's a simple box
with a nic connected to the internet, the housing facility provided
me
with a /64 matching my IPv4 address and told me to setup rtadv.
Quite easy I thought, looking at hostname.if(5), I added a simple
"inet6 alias 2001:41d0:2:1d4f::1 64" to my hostname.sis0, turned
rtadv
Upon reboot, ifconfig shows me
inet6 fe80::21c:c0ff:fe82:9213%sis0 prefixlen 64 scopeid 0x1
Another reboot without the "alias" flag in the hostname.sis0, and
ifconfig gives me the following result:
inet6 fe80::21c:c0ff:fe82:9213%sis0 prefixlen 64 scopeid 0x1
inet6 2001:41d0:2:1d4f::1 prefixlen 64
I made sure pf allows icmp6 through to get the gateway address, but
looking at my routing I suspected something was wrong.
Checking with rtsol I end up with the following result:
# rtsol -d sis0
checking if sis0 is ready...
sis0 is ready
send RS on sis0, whose state is 2
received RA from fe80::5:73ff:fea0:0 on sis0, state is 2
stop timer for sis0
there is no timer
The documentation of the housing facility tells me their routers
are
always on ::FF:FF:FF:FF:FF so I tried a ping6:
# ping6 2001:41d0:2:1F:FF:FF:FF:FF
PING6(56=40+8+8 bytes) 2001:41d0:2:1d4f::1 -->
2001:41d0:2:1f:ff:ff:ff:ff
^C
--- 2001:41d0:2:1F:FF:FF:FF:FF ping6 statistics ---
7 packets transmitted, 0 packets received, 100.0% packet loss
Most documents I found on the web focus on setting up things
through
tunnels as most providers still don't offer IPv6 connectivity yet.
What am I missing here?
The address you're trying to ping is outside of your subnet,
should it be 2001:41d0:2:1d4f:ff:ff:ff:ff ?
$ sipcalc 2001:41d0:2:1d4f::/64 | grep -A1 range
Network range - 2001:41d0:0002:1d4f:0000:0000:0000:0000 -
2001:41d0:0002:1d4f:ffff:ffff:ffff:ffff
netstat -rnfinet6 might give clues.
Thank you for pointing that out Stuart, it was of course the wrong
subnet, but as I figured a while later, the ipv6 configuration
was right, pinging with ping6 -I sis0 returned working replies
from both ipv6.google.com and some other addresses.
I'm not yet very familiar with all the IPv6 subtle changes but
working on it.
Regards.
