I can't get IPv6 routing to configure correctly despite everything I've read saying it should This is my network config on a fully-updated CentOS 5.8 system: # cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=my.hostname.com GATEWAY=aaa.bbb.ccc.ddd IPV6_DEFAULTGW=2a02:aaaa.bbbb::1 IPV6_DEFAULTDEV=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0

Hi there, While I was looking "how to disable ipv6 under centos" I have found a gazzillion pages about how to do it and some of then even list things that i am not sure where they came from, so for the record I list most of them here in case someone else need them. Some of the methods involved the direct modification of system scripts, and I am against that so I wont list them here

I thought I'd done that standard stuff /etc/modprobe.conf: alias net-pf-10 off alias ipv6 off /etc/sysconfig/network: NETWORKING_IPV6=no But on reboot I still see ipv6 entries against the eth devices, ipv6 module is still loaded, and sit0 tunnel is present. What needs to be done to disable ipv6? -- rgds Stephen

Hello, I am doing some tests with asterisk on a dual-stack environment. I have some doubts regarding asterisk binding addresses on a server with 2 network cards. According to asterisk documentation: /; With the current situation, you can do one of four things:/ /; a) Listen on a specific IPv4 address. Example: bindaddr=192.0.2.1/ /; b) Listen on a specific IPv6 address.

I want to seriously work with IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented

How about, in your /etc/sysconfig/network file adding or editing the line for IPV6 to be: NETWORKING_IPV6=no and then try a 'service network restart' and see what you get.

Hello, I'm running a CentOS 5.6 server through linode. I am atempting to configure it for ipv6, previously this had been done though not by me on a ubuntu box so the hardware can take it. I've got an ipv6 tunnel through Hurricane Electric and at a shell prompt have done the following: ifconfig sit0 up ifconfig sit0 inet6 tunnel ::IPV4 Address ifconfig sit1 up ifconfig sit1 inet6 add IPV6

If a site resolves to > only an AAAA record, then it's not reachable whatever we do. For me the code tries to reach the ipv6 address,

Hello, I use Samba AD in Version 4.8.3 and would like to run it on IPv4 und IPv6 in order to be able to have Samba acting as IPv6 DNS Server. However since I have problem with sysprep domain join as soon as Samba advertises its own Domain Controller Hostname as IPv4 and IPv6 address, I would like to tell Samba to run on both protocols but only resolve to an IPv4 address. So in short: When I

Sorry - that should be sysctl -w net.ipv6.conf.all.accept_ra=0 to disable that, not 1.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are

In dovecot conf, for submission relay, I've config'd submission_relay_host = lan.example.com submission_relay_port = 465 hostname -- not IP -- must be used, to inform relay for cert verification match. Here, host lan.example.com lan.example.com has address 10.0.1.47 lan.example.com has IPv6 address fd80:25:01::47 The receiving smtp relay listens only on IPv4 -- no

Hi, I'm currently reading chapter 13 of the RHEL Deployment Guide, and taking some notes. I have a few minor questions: /etc/sysconfig/network According to the doc: "This file specifies routing and host information for all network interfaces." Here's how mine looks like: --8<----------------- NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=fujitsu.zuhause
