Command for assigning IPv6 address and MAC address on the interface

mac address on a interface.

man ifconfig
man 8 ip

Please can you elaborate ? How do you see it does not work ?

Yes, it works for me. You can also assign an IPv6 address with the 'ip'
command from the iproute/iproute2 package :

ip -6 address add 2001:0db8:0:f101::1/64 dev eth0

Note that the 2001:0db8::/32 range is to be used for documentation
purpose only. If you do not have a global prefix you can create and use
a prefix in the unique local address range (ULA, cf. RFC 4193). A
generator is available at <http://www.kame.net/~suz/gen-ula.html>.

Hi,
I got the error
"No support for INET6 on this system."


Thats why I was wondering if the command was wrong
Cheers

What distribution are you running? RH9 or older?

It seems that the kernel or maybe the glibc lacks IPv6 support. What is
the distribution (name and version) ?
Maybe the ipv6 kernel module was not loaded. Try to manually load it
with the following command :

modprobe ipv6

I tried out
modprobe ipv6

I get the error

FATAL: Module ipv6 not found

What is the output of
grep CONFIG_IPV6 /boot/config-$(uname -r)
or
zgrep CONFIG_IPV6 /proc/config.gz

You did not answer about the distribution name and version.

Your problem is that you don't have IPv6 support. Make certain that it is
compiled into your kernel AND into net-tools.
