Disable IPv6 via command?

[peet1]

Is there a simple command to disable ipv6? It seems to like to turn itself back on from time to time and I'd just like to set up a simple script to see if it's enabled, turn it off, then restart a process.

Thanks in advance for any help.

Cheers.Peet

You just disable it from the network settings wheel in the web ui.

I've never seen it come back on.

As @StephenB said, it's actually better to do this type of configuration via the Web UI. This is also because most config parameters are stored in a database and frequently reapplied to the actual configuration files. So your modifications via CLI may get overwritten by the values from the database (as defined in the Web UI).

Thanks guys. I understand what you are saying, and I guess I just wasn't as clear as I should've been.

What I am looking for is a way to call the same sub system that is called by frontview so that my settings don't get stomped on by ReasyNAS OS.

I'll keep poking a stick at it. If anyone has any advice to achieve this, it would be greatly appreciated.

It is possible that it's something I've done that turns it back on. But another part of what I need is a reproducable environment across multiple NAS's that doesn't require me to touch every one.

Thanks.Peet

You could try

1. sysctl -w net.ipv6.conf.all.disable_ipv6=1
2. sysctl -w net.ipv6.conf.default.disable_ipv6=1
