Turn off IPv6

[Brad_G]

We recently had a configuration change to our AD domain controllers which has caused an issue with our 10.5 clients.

I'm looking at an easy way with Casper to turn off IPv6 on the 10.5 clients.

If I take the /Library/Preferences/System Configuration/preferences.plist file from a machine I turned IPv6 off I also get the computer name and other unwanted data. Has anyone tried this before? I'm not a script guru so I haven't ventured down that path.

This will be a temporary fix as we're updating the OS for out fall semester.

Thanks for any suggestions or pointers.
Brad

Have a look at man networksetup.

I think this will work;

#!/bin/sh

sudo networksetup -setv6off Ethernet

But test test test.

I had to do that recently due to our Meru wireless controllers having issues with ipv6 enabled.

You have to disable it on each interface.. So my script is:

#!/bin/sh

# ipv6-off.sh
#
# Disable IPv6 on all interfaces.
#

/usr/sbin/networksetup -setv6off "Built-in Ethernet"

/usr/sbin/networksetup -setv6off "AirPort"

/usr/sbin/networksetup -setv6off "Ethernet"

/usr/sbin/networksetup -setv6off "Ethernet 1"

/usr/sbin/networksetup -setv6off "Ethernet 2"

This command disables IPv6 on all the active network interfaces.

networksetup -listallnetworkservices | sed "1d" | while read output ; do networksetup -setv6off "$output";done
