IPv6 disable

Some users might want to disable IPv6 on the system (if it’s not disabled in the image release). The best way to disable it on router. Nevertheless here is how to do it for one host by executing the following one-liner.

This adds ipv6.disable=1 to GRUB options, updates it and reboots

sed -i 's/^GRUB_CMDLINE_LINUX_DEFAULT=.*/GRUB_CMDLINE_LINUX_DEFAULT="text consoleblank=0 intel_pstate=disable net.ifnames=0 ipv6.disable=1 pci=noaer iommu=soft amdgpu.vm_fragment_size=9 radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1"/g' /etc/default/grub && update-grub && reboot

Run this from terminal or from web “Linux Shell”.
