Disable ipv6 from uboot

How can I disable IPv6 in the kernel from uboot?  I am using a ZyXel NSA 320

Re: Disable ipv6 from uboot

That sounds like something you should ask on the uboot mailing list. I suppose not many here will be familiar with uboot.

Re: Disable ipv6 from uboot

I'm not sure if it's Ubuntu-related: http://www.wiki.xilinx.com/U-boot , more like ARM-related.

Re: Disable ipv6 from uboot

Moving to Other Architectures.  Unfortunately, U-boot is definitely in the realm of ARM.
this article may give some clues.  It is not obvious how to pass command line parameters in U-Boot, but maybe you could do what you need in /etc/sysctl.d/40-ipv6.conf.  Or, you could build a custom kernel that turns off that capability.

I had been looking at that link and there is a useful link from that page with instructions on how to disable IPv6 in the kernel using kernel parameters in various boot loaders, just not uboot.

I have found this article.  Looks like I just need to determine how to make them persist.

Re: Disable ipv6 from uboot

This looks promising.  I'll verify if I can disable IPv6 and mark the post appropriately.

help saveenv
saveenv - save environment variables to persistent storage

Usage:

Re: Disable ipv6 from uboot

bzhao,

Welcome to Arch Linux and thank you for a valid contribution to the thread.

As this thread is two years old, I am going to go ahead and close it.  I also will note that over the last couple years, the moderation team has decided that we should consider Arch Arm to be a separate distribution.  As we do with all other Arch based distributions, we suggest that topics regarding those distributions be handled by the respective forums.   As this thread has been around awhile, I consider it to be "grandfathered" so I will leave it in this subforum.  On the other hand, it is probably time to close it.
