I found a really quick fix today for disabling ipv6 completely on Ubuntu 7.10 (not yet tested on previous versions). This might be of interest to some of you that have had networking problems, as I’ve heard disabling ipv6 at least within the browser has been a help here. This tutorial will disable ipv6 completely on the machine. At this point activating or disabling ipv6 probably wont make much of a difference as very few people actually implement or use ipv6. Unless you know you have a reason to need (or not need) this, you can probably safely leave it where it is.
Disabling ipv6 on Ubuntu 7.10
We’ll simply need to change a line in one of the configuration files that loads the ipv6 module to the kernel. As of yet I have not figured out a way to update this change outside of restarting the machine. If anyone has any suggestions on removing ipv6 “live” I would appreciate it.
Change the line is /etc/modprobe.d/aliases from:
alias net-pf-10 ipv6
alias net-pf-10 off
Again, at this point you’ll need to restart your machine for the change to take place. If anyone knows of a way to avoid the reboot I would appreciate it.
