Re: How-To: Disable IPV6 to speed up Internet.
i do make backups regularly. i have yet to figure out how to get my OS "the way I want it," despite pouring hundreds of hours trying to figure it out. Instead I have settled for getting it mostly functional with regular backups and a harried frenzy whenever something seemingly straightforward gets in the way. For example, it took me (brand new to linux) a little under a week to figure out how to even make and restore a backup. still not even sure i've got the whole "dereference vs no-dereference" thing sorted out ... and you think it's even documented? yes there are exhaustive, cryptic, and circular references to lots of stuff in the man entries pages... mostly useless unless you already understand the jargon.
anyway, you're right it's off-topic and i guess i'm just venting.
cheers
Re: How-To: Disable IPV6 to speed up Internet.
Disabling IPv6 has just done wonders to Azureus for me. I struggled to connect to any peers, each connection seemed to time out and I'd only manage a trickle from them with EVERY torrent I tried (easily 50 or so, all well seeded). I added 'blacklist ipv6' into /etc/modprobe.d/blacklist and rebooted. [Running Edgy]
Instantly I could see the difference. I am now saturating my available bandwidth. 8)
Firefox seems to have become much snappier too. I'm hoping this may also have sorted my MSN troubles as messages were being dropped all the time in any client I used. Here's hoping. I assume this all more than pure coincidence!
Thanks!
Re: How-To: Disable IPV6 to speed up Internet.
I just wanted to say thanks for all the good info. regarding the IPv6 slow down issue. I got version 6.06 LTS running fast by changing the IPv6 line in the "aliases" file. Previous methods didn't seem to work.
There is also an interesting article about IPv6 on the MS site at -
http://www.microsoft.com/whdc/device.../IPv6_IGD.mspx
Does anyone know of an equivilant Linux article in this same area? In my view, the U.S. needs to get to IPv6 ASAP. The Telco crap where they want you to use DHCP and then lease you an IP address for 15 minutes to a day and then it's gone is stupid. I already have several internal devices where I'm at that I would like to have static IP addresses for so they can be reached easily and directly from the Internet. The Telcos where I'm at either don't offer them or want big bucks for them. 2 to the 128th power, the last time I calculated, equates to approx. 6.2 times 10 to the 25 power for every sq. ft. on the planet.
I guess if you make everyone think the supply is limited, you can charge more.
Thanks Again :-)
Re: How-To: Disable IPV6 to speed up Internet.
Ok guys, i've followed all your instruction an modified IPv6 lines in modprobe, but still the command
ip a | grep inet6
returns me some output, sign that IPv6 is still enabled.
Then, what can i do now?
Re: How-To: Disable IPV6 to speed up Internet.
I just started using Linux (Ubuntu 6.10)and I couldn't get any app to connect to the Internet. Disabling ipv6 using "blacklist ipv6" as described on this thread worked for Firefox but not for Synaptic. But then I followed the instructions on http://ubuntuforums.org/showthread.php?t=282034 using that OpenDNS service, and everything seemed to work fine. Now I just re-enabled ipv6 everywhere and everything still works! So maybe, as some posters have said, the problem is not in ipv6 per se. For me at least, it seemed to reside on the DNS service I was using.

If you get errors doing this, you should
sudo gedit /etc/modprobe.d/blacklist
then insert this line:
blacklist ipv6
This works for me in 6.10 Edgy
Re: How-To: Disable IPV6 to speed up Internet.
I seem to be having a problem trying to speed-up Firefox. the following is what I have tried so far with the result. Have I done this correctly? Any help is greatly appreciated.

Re: How-To: Disable IPV6 to speed up Internet.
To disable IPv6 in Firefox
1. Type about:config in the address bar
2. Enter network.dns.disableIPv6
3. Change the value to true. Double click the line to enable/disable. Enabled=true / Disabled=false. This will disable IPv6 dns lookups from within Firefox only--not your entire Ubuntu system.
To do it for the entire system:
Keep in mind that there are a number of ways to accomplish this.
1. Verify that the IPv6 module is loaded. From a terminal type:
Code:
dbott@thedrake:~$ lsmod | grep ipv6
ipv6 265856 10
2. From a terminal type:
Code:
sudo echo "blacklist ipv6" > /etc/modprobe.d/blacklist-ipv6
3. Restart
4. Verify that the IPv6 module is not loaded. From a terminal type:
Code:
dbott@thedrake:~$ lsmod | grep ipv6
dbott@thedrake:~$

Wow success!! This old Compaq Laptop is much faster surfing the internet now! Thank you all for your help. It's got to be tough dealing with nubes! hehe Keep-up the fantastic work.

Re: How-To: Disable IPV6 to speed up Internet.
One more noob-type question, if we're diabling IPv6 to improve performance and avoid loading stuff we don't use, why don't be disable atm, appletalk and the rest of the protocols we'll never use while we're doing this?
