(usagi-users 02073) Problem about 6to4 tunnel.

[Tomofumi Hayashi <thayashi@xxxxxxxxxxx>]

Hi.

I try to make an IPv6 over IPv4 tunnel.
My linux box uses Kondara Linux 2.1 and usagi (20021209-snapshot) and it has
two network cards(eth0 and eth1). At first, I try to use it as only v6 host.

During the experiment, there are some problems.

bash-2.05$ iptunnel
sit0: ipv6/ip  remote any  local any  ttl 64  nopmtudisc
sit1: ipv6/ip  remote 150.65.236.22  local any  ttl 64
bash-2.05$ ifconfig sit1
sit1      Link encap:IPv6-in-IPv4
          inet6 addr: fe80::9641:2913/64 Scope:Link
          inet6 addr: fe80::c0a8:1/64 Scope:Link

IPV6ADDR=fe80::9641:2913/64
IPV6_AUTOCONF=yes
#(The machine "150.65.236.22" is a Solaris8 workstation)
-------------------------------------------------------

I try to send a ping to bloadcast address, but it failed. Then I delete the 
sit1 addr(fe80::c0a8:1/64), and it succeed. So, I want to change the addresses
 that sit1 binds in "/etc/sysconfig/network-scripts/ifcfg-sit1".

How to change the files ?

Thanks.
