...good idea). How to disable ipv6 support in Centos 4.x Pick any method, a combo or all of them Method 1, add the line: alias net-pf-10 off to the /etc/modprobe.conf Method 2 Add to /etc/sysconfig/network file: NOZEROCONF=yes # Bonus: Disable the ugly generation of 169.254 zeroconf networks. NETWORKING_IPV6=no Note about method 2. I must mention the fact that I actually READ the entire ifup script and dependencies and I found that it calls at line 361: # if [ "${NETWORKING_IPV6}" = "yes" ]; then # /etc/sysconfig/network-scripts/ifup-ipv6 ${CONFIG} However adding the NE...

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 out all of the IPV4 lines in ifcfg-lo. Still have IPv4 on lo. How do I di...

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.

...r 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 GATEWAY=192.168.1.254 --8<----------------- NETWORKING_IPV6= -> I wonder if I can switch that to 'no', since I simple don't use IPV6.

...o solve. Every DNS lookup results in AAAA records being requested first before A records. As a result, this causes a large amount of unnecessary DNS traffic on the network. IPv6 has been completely disabled on these servers: /etc/modprobe.conf, ipv6 off and net-pf-10 off /etc/sysconfig/network, NETWORKING_IPV6=no lsmod | grep ipv6 shows the kernel module no longer loaded. Yet watching TCP dump shows that AAAA records are requested before A records every time a login is requested from one of our local machines to another. Is there some sort of configuration directive I can use to force IPv4 lookups...

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

I have a fairly vanilla install of Centos5 on a desktop box (with a Broadcom NetXtreme BCM5752 Gigabit NIC). When booting, the boot process hangs at "Applying ip6tables firewall rules" for 30-60 seconds before proceeding, which is annoying. I have not tried to turn off ipv6 networking. I guess I could, but is this slowness to be expected? Is it waiting for some ipv6 response?
