Disable ipv6 in linux

Ipv6 is designed to address ipv4 address insufficiency. Many IDC vendors are now using ipv6, but sometimes we do not need ipv6. How can we disable it?

. Modify the corresponding Nic of/etc/sysconfig/network and append the following:

The Code is as follows:	Copy code
NETWORKING_IPV6 = no

2. Modify/etc/hosts and comment out the local host name resolution in ipv6:

The Code is as follows:	Copy code
#: 1 localhost localhost6 localhost6.localdomain6

3. Create the file/etc/modprobe. d/ipv6off. conf (name as needed)

Note: The/etc/modprobe. conf file is missing after RHEL6.0.

The Code is as follows:	Copy code
Alias net-pf-10 off Options ipv6 disable = 1

4. restart the system and then confirm:

The Code is as follows:	Copy code
[Root @ test ~] # Lsmod | grep-I ipv6 [Root @ test ~] # Ifconfig | grep-I inet6

If the execution results of the preceding two commands are not displayed, ipv6 is completely forbidden.

Others:
In the method of not loading the ipv6 module, someone may set it like this:

The Code is as follows:	Copy code
Alias net-pf-10 off Alias ipv6 off Options ipv6 disable = 1

Although ipv6 is not loaded after the system is restarted, in some versions, when we restart the network, the following error occurs: FATAL: module off not found.

RedHat 5.x

To disable IPv6 in a virtual machine running RedHat 5.x:
1. Log in as root or superuser. www. bKjia. c0m

2. If the/etc/sysconfig/network file contains the line NETWORKING_IPV6 = yes, change the line:

NETWORKING_IPV6 = no

 

3. In the file/etc/modprobe. conf, add this line:

Options ipv6 disable = 1

 

4. Save the file and reboot the system.

After you disable IPv6, you should be able to install and configure VMware Tools successfully.
