disable ipv6 modules

mobidyc — Wed, 12 Aug 2009 11:31:31 GMT

Hello,

I want to disable IPv6 on my servers.

If i try to disable the ipv6 module:
# kcmodule ip6=unused
* The automatic 'backup' configuration has been updated.
WARNING: The module 'ip6' could not be set to unused state, because
another module depends on it.
Module State Cause
ip6 static depend

the dependency is "interface HPUX_11_23:1.0"
# kcmodule -v ip6
Module ip6 [4A730866]
Description IP IPv6 Driver
State static (to resolve dependencies)
State at Next Boot static (to resolve dependencies)
Capable static unused
Depends On interface HPUX_11_23:1.0

what is this interface ?
how can I disable this dependency ?

Thanks for your help.

Cheers,
Cedrick Gaillard

Shalom Cedrick,

A reboot is required to make this change.

After reboot I believe your changes will work.

I think disableling, turning off IPv6 in HP-UX is not possible. You can choose not to use it, but it goes that far...

Look at this topic:

Shalom Steven,

the error message indicates the driver can not be in unused state because of a dependency, a reboot wil change nothing (i know, i tried).

when a reboot is required, this kind of message appears:
# kcmodule mip6mod=unused
NOTE: The configuration being loaded contains the following change(s)
that cannot be applied immediately and which will be held for
the next boot:
-- Moving a module into or out of static state requires a kernel
rebuild.
* The automatic 'backup' configuration has been updated.
* Building a new kernel for configuration 'nextboot'...
* Adding version information to new kernel...
* The requested changes have been saved, and will take effect at
next boot.
Module State Cause
libmip6 (now) static depend
(next boot) unused
mip6mod (now) static best
(next boot) unused

Chers,
