Thanks Bjørn for the reply. But with the grub command line, IPv6 option is not available i.e.* net.ipv6.conf.all.disable_ipv6* i.e. net.ipv6 itself is not available.
$ sudo sysctl net.ipv6 sysctl: cannot stat /proc/sys/net/ipv6: No such file or directory I want to enable and disable IPv6 when the Linux box is up and running. Sysctls worked but not for new namespaces. Is this a limitation of Linux? BTW, the value is still 0 for disable_ipv6 $ cat /sys/module/ipv6/parameters/disable_ipv6 0 Dheeraj On Tue, Jun 7, 2022 at 2:38 PM Bjørn Mork <[email protected]> wrote: > Dheeraj Kandula <[email protected]> writes: > > > Thanks Bjørn for your response.
