Hi,

I found the solution for those who tried all the alias stuff and none of it worked.

Goto the menu System->Administration->network

Once the network tool loads, goto the Hosts tab.

CHANGE ALL the ip6 text to ip4

Close and then ping something on the network, it may take some seconds to readjust itself.

Thanks.

I’m having the same problem with IPV6 in use,

Jeff Schroeder, could you give us a step by step guide for us newbie linux users, thx
(ie ” you have to stop your networking, unload ALL related networking modules, and finally ipv6.

Then you can modprobe them all again (sans ipv6) but it is much easier to just bounce the box.”)

For me disabling IPv6 on Gutsy disables all networking. I still have a v4 address, but can’t connect to anything except localhost.

I also needed to do the blacklist in order for it to work. I’m on 64 bit Ubuntu Gutsy. It looks like the original steps (modifying /etc/modprobe.d/aliases) disabled ipv6 on my wired connection (eth0), but not on my wireless (wlan0). Blacklisting disables both, and now I can connect fine.

only this one worked on Ubuntu 7.10 aka Gutsy add the following line to /etc/modprobe.d/blacklist :

blacklist ipv6

I’ve tried all of the above and it is still there. Blacklisted it removed/changed in /etc/modprobe.d/aliases and rmmod -f ipv6 etc. It depends on:

ipv6 317192 17 nf_conntrack_h323

Seems it won’t go away. Hopefully vmware 2 will still work.

I’m using 64bit Kubuntu.

Maybe it would be worth mentioning why this “workaround” has any effect at all on some systems… and what the real solution should be.

I used to disable IPv6 on Fedora the same way. However, on Ubuntu, I just add the following line to /etc/modprobe.d/blacklist:

blacklist ipv6

I thought this was the “right” way to do it (not sure where I got that idea), but I doubt there really is any such thing…

# On lines that start ‘alias net-pf-10′, find ‘ipv6′ and change it to ‘off’. (for those who don’t know)
sudo sed -i ‘/net-pf-10/s/ipv6/off/’ /etc/modprobe.d/aliases

Since the ipv6 module is going to complain about being “in use” if you try to force unload it, you have to stop your networking, unload ALL related networking modules, and finally ipv6.

Then you can modprobe them all again (sans ipv6) but it is much easier to just bounce the box.

What about?

rmmod ipv6
