Disable ipv6 in ubuntu?

ksgill · 05-24-2005, 12:31 PM

Hi,

My internet is extremely slow and I think the problem lies with ipv6 protocol that it uses. My /etc/resolv files has the correct name server and domain information. I remember disabling ipv6 in suse by modifying the /etc/modprobe.conf file.. how do I do that in ubuntu ? Does someone have any other suggestions? My suse comp. uses the same internet connection and works fine while ubuntu is awfully slow.

Thanks in advance.

U can disable it with modconf(man modconf).

i don't know what an ubuntu is but ..........
you might be able to undo ipv6 with
alias net-pf-10 off
in /etc/modprobe.conf

Code:

alias ipv6 off
alias net-pf-10 off

that's what I have in modprobe.conf. Not sure if it works properly though. I also added this to /etc/resolv.conf

Code:

nameserver 4.2.2.2

makes web browsing really quick

Cheers!

There is no modconf in ubuntu (it's a debian based distro)

Code:

root@ubuntu:/home/gill # modconf
bash: modconf: command not found
root@ubuntu:/home/gill # man modconf
No manual entry for modconf

I also pointed out in my first post that this distribution does not have /etc/modprobe.conf

Any other ideas folks.. it's really annoying

Alright, finally figured it out. The file in ubuntu that needs to be modified is /etc/modprobe.d/aliases and you need to turn off aliases net-pf-10 off to disable ipv6. I dont even know why every distribution is turning on ipv6 by default. It is not a standard right now..will be sometime in the future. One of the most annoying things for someone who doesnt know about it

Does disabling ipv6 in your browser do the same?

In Firefox for example:

Yes!

This really worked well for me. I advise everyone to use it.
