if you are running slitaz 3, installed linux-ipv6, you can use ipv6 on your computer.. but incoming packets are gonna mess if you dont enable bind ipv6 in the sysctl.

i explain : by default slitaz 3 doesnt handle ipv6. You can install it.

then you will see that only ping/icmp can reach your computer by ipv6, but ssh is not allowed on v6.

to fix this, just add in you /etc/init.d/local.sh :

    sysctl -w net.ipv6.bindv6only=1

with this, ssh should allow incoming ipv6 connections
