fedora real disable ipv6 and disable sit0

[ssb]

Hello,

I am trying to disable ipv6 and ipv6 tunnelin ipv4 - sit0 inteface

But boot log shows
ip6_tables: (C) 2000-2006 Netfilter Core Team
IPv6 over IPv4 tunneling driver

are these modules loadings? how to disable it ?

And yes, i think that ip6 is on ...

$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 6c:f0:49:7d:e7:97 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.4/24 brd 192.168.1.255 scope global eth0
3: sit0: <NOARP> mtu 1480 qdisc noop state DOWN
link/sit 0.0.0.0 brd 0.0.0.0

I am tried with

blacklist ipv6

and into a file in modprobe.d directory with :

install ipv6 /bin/true

alias net-pf-10 off
alias ipv6 off

and no results

help

Looks to me as if this is the ipv6 iptables firewall. You can confirm this by running ckconfig --list. If my guess is true, you would see two iptable firewalls, one for ipv4 and another one for ipv6. If you don't need the ipv6 firewall you can disable the service.

I got firewalls disabled:

ip6tables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
