Hi,
I would like to disable ipv6 on my FC6 x86_64 with the kernel
2.6.18-ovz028stab031.1-smp

I try to set on modprobe.conf this alias
alias net-pf-10 off
alias ipv6 off

but if I try ifconfig
eth2 Link encap:Ethernet HWaddr 00:08:A1:3C:52:E7
inet addr:192.168.251.2 Bcast:192.168.251.3 Mask:255.255.255.252
inet6 addr: fe80::208:a1ff:fe3c:52e7/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

RX bytes:28980866 (27.6 MiB) TX bytes:28980866 (27.6 MiB)

It seems that ipv6 is active
Is it possible to disable it?
Thanks

Cristina

Hello,

As far as I remember on FC6 there is /etc/sysconfig/network file:

# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain

You can use it to trigger ipv6.

However, this operation, certainly will not remove "inet6 addr: ..." line from ifconfig output. It is ok: IPv6 support is compiled in OVZ kernels, but interface will use the protocol (IPv4 or IPv6) which user wishes! Wink

So this line shouldn't worry you.

HTH,
Vasily.

I set this options

[shaggycat@hn ~]$ cat /etc/sysconfig/network | grep NETWORKING
NETWORKING=yes
NETWORKING_IPV6=no
[shaggycat@hn ~]$

But, why some servises on HN bind from ipv6:

[shaggycat@hn ~]$ netstat -nl | grep LISTEN | grep -v unix
tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      
tcp        0      0 0.0.0.0:4000                0.0.0.0:*                   LISTEN      
tcp        0      0 10.0.10.3:4001              

.....

0.0.0.0:*                   LISTEN      
tcp        0      0 0.0.0.0:4662                0.0.0.0:*                   LISTEN      
tcp        0      0 :::22                       :::*                        LISTEN      
tcp        0      0 :::80                       :::*                        LISTEN      
tcp        0      0 :::959                      :::*                        LISTEN      
[shaggycat@hn ~]$

What's wrong?

Thanks.
