Ubuntu Installation :: Zero Internet Connection With 10.10 Via IPv6?
Oct 17, 2010
Luckily I have a second machine running 9.10 and could get onto the net for assistance.
I tried all sorts of modifications to sysctl, modeprobe files, etc and checked all over google for a fix.
It appears that the IPv6 settings are part of the kernel, in this case I am going back to 9.10 and staying with 9.10 until this IPv6 is sorted out. Most home routers do not have IPv6 connections, only IPv4. This lack of Internet connection has happened with both server and desktop. I do not know the reasoning behind this decision but I will not be upgrading to 10 until IPv6 is sorted for me as a home user.
Able to boot with different partitions of a 320 GB hard drive with Windows Server 2008, Ubuntu server 9.10 plus Ubuntu desktop 9.10 but IPv6 with 10.10 installs on the respective server and desktop partitions does not allow a lan connection to the router. All are 64bit downloads.

I installed ubuntu yesterday on my desktop. I noticed that the global internet connection is very slow (browsing,downloading from apt-get, etc).

I have a small wireless network running IPv6 connected though a 802.15.4 usb stick, and a network connection through eth1. I can access the nodes on the wireless network from my computer, but not from any other on the wired LAN. Also the nodes on the wireless cannot see even the address of eth1. I'm guessing i have to forward all packets from the wireless to eth1 in some way, but am unable to find an guides for this with IPv6.

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

I am wondering how I can share connection with my IPv6 connection.
I am using slackware and ip6tables so far. But the problem is that IPv6 or ip6tables has no "-t nat", so how could I just simply share Internet with the computers behind the firewall?

I'm using Internet connection through local network, receiving white (global) IP, route, DNS with local DHCP server. Lately I noticed that my Ubuntu gets ipv6 autoconfiguration from ISP router, receiving global ipv6 address and automatically adding ipv6 route. I can access Internet resources using ipv6 connection:
I can ping inet resources using my ipv6 global address and access, for example, ipv6.google.com or URL..
How can I share ipv6 connection to my home network? Using ipv4 it's easy, I just can use NAT for this. But if I understand correctly, in ipv6 there isn't such thing as NAT, because there is no limit in ip addresses.

The installation of Ubuntu 9.10 on my HP NC640 worked fine and the network adaptor was successfully recognised: I see the message 'Wired Network Connection 'Auto Eth0' active' and when I open Active Network Connections I see the IP addresses that have been assigned.
However, if I open Firefox, I cannot connect to the internet. I tried pinging some addresses (www.yahoo.com) and that seemed fine. I then tried to run a first system update and Ubuntu seemed to be able to retrieve some packages but not others.
I then tried opening 'Network Connections' and adjusted the MTU (to 1100) and changing the settings of IPv6 (various settings: eg. 'ignore') but none of that seemed to help. Here I wanted to switch off IPv6 but it looks like none of the settings did this. Is there maybe another place where I should be looking? Do I have to do this with the command line? (I hope not) Or can I switch off IPv6 in the system settings? And should MTU be automatic? Or should I set something there?

Is karmic is slower for you all: if you're running windows ping a server on windows/ubuntu and compare. 9.10 is consistently slower for me. I've seen enough "slow internet" posts to suspect that someone screwed up bad. Everyone says it's ipv6, but none of the fixes work for me. Pretty sure it's ipv6 (or at least a dns-related problem):

I have installed Ubuntu 10.10 on my laptop, and the internet was very slow and kept dropping in and out for any web browsers and sometimes the Ubuntu software center. After searching the internet for a while I came across several article saying to disable ipv6, which I have done, but the issue persists

I'm having a little problem here. That, or I'm missing the obvious staring me in the face. I have this file server, called toad. I nuked it's system disk, reorganising the partitions and upgrading to openSUSE 11.3 x64. I installed vsftd with "Yast FTP server", and the config looks OK. I even compared it with that of another machine. But when I try to connect, this is what I get:
user@mainmachine:~> ftp
ftp> open toad
Connected to toad.geuens.org.
500 OOPS: could not bind listening IPv6 socket
I'm prettige sure IPv6 is deactivated. The firewall is disabled on both machines. I've looked this over again and again. Can't find it. It's not the connecting machine, I've tried from another.

I have seen several threads lately about slow internet connections here and elsewhere, but I haven't seen anyone post a reply about blacklisting ipv6 so I am curious as to why?Is ipv6 enabled only on certain distro's or is there some other reason that it's not mentioned?
<If anyone wants to try it, to see if it would work for them>
On Slackware 12.2 and Salix 13.0 just add "blacklist ipv6" to the /etc/modprobe.d/blacklist file. I'm not sure about non-slackware based distro's. Unfortunately, I don't know any way of doing it without rebooting.

I recently bougt an Asus N61DA with Windows 7. I decided to install Ubuntu alongside Windows, so I made the Ubuntu CD, just like it said. Then I inserted the CD and restarted the computer. I started the installer (ubuntu 10.10 64-bit) and chose the option where it says "install ubuntu alongside other operating systems", or something like that. So, the installation started, but then I lost the internet connection, and the installation stopped.I re-connected the computer, but the installation still wouldn't continue. I restarted the computer and then nothing happened. I've restarted it several times, but still nothing happens. I've inserted the Windows recovery CD, but it doesn't work

I'm a pretty new ubuntu user and I've just upgraded from 10.10. It seems to be working pretty well, except that I can't figure out how to connect to the Internet. When I click the wireless icon to try to connect, the drop down menu is as follows:
Wired network (grey/unclickable)
Disconnected (grey)
JackET N8 (grey)
Disconnected (grey)
3 Internet (white/clickable)

I have just installed ubuntu 10.10 on an Acer Aspire 3610 notebook. 2 GB RAM. This notebook had Internet access previously via Windows XP (now erased). Here is the partitioned drive. Two ext4 partitions for ubuntu "/" and "/home". Two ntfs partitions possibly for Windows. I have booted up the fresh installation of ubuntu 10.10. I had some glitch where I saw "Operating system not found' on booting from HDD and I wondered if this was due to failing drive.
But I've run a full test using Disk Utility and it shows as healthy. This message has gone away (I don't know why) and I can boot into ubuntu. The problem I'm trying to solve is simply no internet connection. Here are some outputs from commands ..

Sorry title should have been F13 installation without internet I am having a P4, 1GB ram, 80 GB machine. Since yesterday I am having some funny issues on this machine. i have fedora 12 installed on this machine.
My mouse suddenly stop working, or the cursor changes from pointer type to a line cursor and basicaly the mouse just stops clicking. I am plannning to install fedora 13 on this machine. Have downloaded the 5 iso (
CD images).
Would choosing the option upgrade on existing Linux partition do the job? Is there a chance I loose my data files when the upgrade is done? I dont want to reinstall programs like java, eclipse, tomcat etc that I done in fedora 12. I only intend using the CD's as I dont have a lot of bandwidth and a fast internet connection to use yum.

I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.

Loss of internet connection after upgrade from 8.04 to 8.10 Like the title says, I lost my internet connection after upgrading my Ubuntu system from 8.04 to 8.10.I used the downloaded automated method. It appeared to work fine on its initial reboot into 8.10. But I noticed the internet icon indicated loss of connection. Even so, I was still able to browse the net through Firefox. But then when I rebooted the next day the opposite was true: the connection icon indicated connection, but Firefox would not actually connect, nor would update manager. It has been like this since. This is a dual boot machine, and the Windows XP Pro side still connects to the internet as usual, no problems.So how can I make my new 8.10 system connect to the internet?
I use a Motorola SB4200 cable modem

I just recently Ubuntu 9.10 and have never used Linux at all before. I was wondering, all the links and tips and everything tell me to use Ubuntu Software Center. I haven't had a chance to actually go to the Software Center yet but does it require an internet connection to install software or can I download the tar.gz / tar.bz2 files from sources such as Softpedia.com and still install them using Software Center without a Internet Connection?

I don't yet have an internet connection on my machine so I am using cyber cafes to do my research and whatnot. However, most of the stuff I read concerning updates and installations rely heavily on the machine using an internet connection to automatically install various packages.I don't mind reading up myself on this kind of thing but I think I need a pointer in the right direction as "ubuntu package install without apt/get" doesn't bring up much on a google search (the only entry on the first page is a post on this forum back from 2005 about kernal compiling!).
As an example, the file I would like to install is "aircrack-ng-1.0.tar.gz", which I've already downloaded and saved to my machine's desktop. I'm not really asking how to install aircrack, per se, but just any kind of package without relying on an internet connection (i.e. download the program/package to a flash disk and then on to my machine).

I upgraded to ubuntu 10.04 lts yesterday. The upgrade went smoothly. but now I have a very slow internet connection. It is as if I am on a dial up when I have a broadband speed of 20 MB. What can I do to fix or perhaps roll-back the installation to the previous proper working state.

On trying to install Ubuntu 10.10, one PC was fine. I attempted to install it on a Lenovo Q150 using the Ubuntu Live CD, but it did not recognize a network connection. When the same PC is running Windows 7, the network connection is fine (it recognizes my NAS drive also).Has anyone else had this problem/found a solution? I'm sure that someone else has posted this, but a couple of hours' searching revealed nothing.

I tried to download some software from the Ubuntu software center, and it does not download. It does not give me an error message, it just stays at 0 bytes. It eventually tells me to check my internet connection. (this does not make sense because I am using it to write this thread) I checked synaptic package manager for correct proxy settings and it was ok. I ran
Code:
sudo apt-get update
but to no avail. I am using wireless, and recently dissembled the computer to disconnect the CMOS battery, but I think that it was put back together properly.

I did an upgrade over the internet and on rebooting after it had completed there was no internet connection. I wired in an ethernet cable and although I can access the router and ping another machine on the network, there is no internet connection.
