Disable IPv6 and Enable IPv4 in Red Hat Linux
check “disable_ipv6″ file to check if IPv6 is disabled,enter:
[root@devops ~]# cat /proc/sys/net/ipv6/conf/all/disable_ipv6
0
if you get “0” value, it means that IPv6 is enabled and “1” means it is disabled.
How to Disable IPv6 in linux system?
vim /etc/sysctl.conf
Adding the below lines into that file:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
Save and close that file, then restart sysctl with the following command:
[root@devops ~]# sysctl -p
Now you can rerun the “ifconfig” command to check if IPv6 lines have been removed.
To Enabled IPv4
Edit “/etc/sysconfig/network-scripts/ifcfg-eth0″ file, which is your defualt first NIC configuration file.
If you are using DHCP server to take IP then, edit it like this;
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=”yes”
BOOTPROTO=”dhcp”
Save & restart networking service,
#service network restart OR
#/etc/init.d/network restart
