Hi all, new to the group and want to learn more about
IPv6 and need a little help. Here's where I am at:
First things first, running linux, here is output of
uname -a:
Linux metro 2.4.25-gentoo-r1 #1 Mon May 10 08:53:01
EST 2004 i686 AMD Athlon(tm) XP 2600+ AuthenticAMD
GNU/Linux
My firewall is disabled, and I am connecting to the
internet through a wireless router (Linksys BEFW11S4),
which is connected to a normal router (Netgear RP614)
connected to my DSL modem (Westell WireSpeed).
Kernel is compiled with IPv6 enabled and the command:
# test -f /proc/net/if_inet6 && echo "Running kernel
is IPv6 ready"
tells me my kernel is IPv6 ready. Now I have
installed all the ipv6 utils such as ping6, etc and
iproute2. Following along in the howto, I tried this
command to test:
ping6 -c 1 ::1
and I got the correct response, packet was not lost.
However, when I attempt this (for example):
ping6 -I eth0 -c 1 fe80::2e0:18ff:fe90:9205
I get 100% packet response when it finally quits
trying. I also tried 3ffe:b00:c18:1::10 and the same
response. In an attempt to see where the problem was,
I executed the command with strace appended to the
beginning of the command,
strace ping6 -I eth0 -c 1 fe80::2e0:18ff:fe90:9205
and here is the result (Long result, I believe the
relevant part is at the end, however I will include
the entire output)
----begin output----
