Ubuntu Networking :: 9.10 Internet Slow ... Tried Disabling Ipv6
Feb 1, 2010Is 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):

Ubuntu Networking :: Internet Very Slow In 10.10 After Disabling Ipv6?
Jan 23, 2011I 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

Oct 17, 2010Luckily 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.

Ubuntu Networking :: Firefox - Disabling Ipv6 Through The "about:config" Option
May 29, 2010I am having some hang issues with firefox and am not sure what can be the problem. Here is my specs:
Toshiba Satellite L35 Laptop
Ubuntu 10.4 Lucid / Windows Vista Home Basic dual boot
Atheros Integrated NIC
Firefox v3.6.3
Everything is working fine on the network side, being confirmed by both my wife's EEE Netbook, and my iPod(r) Touch. There is no problem with my network interfaces, or my interface card, as confirmed by the other devices' ability to connect and browse at normal speeds.
However; with my lappy running Ubuntu and Firefox, a LOT of websites hang/lag when attempting to browse websites. I have read on some of the forums about disabling ipv6 through the "about:config" option and that seemed to help a little, but not to where it should be. I have tried a lot of options, but it is still lagging.
Ubuntu :: Disabling Ipv6 In 8.08 Hardy LTS?

OpenSUSE Network :: IPV6 Disabling In Suse In General?
Apr 10, 2011I've had a hell of a time with this and now all but YAST2 are ok. Going back some time to 10.0 this could be used to disable it very completely.
open terminal and run
echo "alias net-pf-10 off" >> /etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf
restart computer. Has anyone used this on more recent issues even 11.4 and are there any repercussions?I assume that the inverse will but it back on ie off's just become on's? I will be using cups when I install my printer which is one concern and I am not at all sure that modprobe will do anything anymore?
I also recollect that there is a command to cause the kernel to effectively reboot which would save restarting. Can't remember what it is. Maybe some one can refresh my memory.
Ubuntu Networking :: How To Share IPv6 Connection
Nov 15, 2010I 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.

Feb 18, 2011I 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?

View 2 Replies View RelatedUbuntu Networking :: How Can I Share Ipv6 Connection To Home Network
Jul 25, 2010I'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.
Ubuntu Networking :: IPv6 - MTU And Network - Cannot Connect To The Internet
Jan 10, 2010The 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?
Networking :: Blacklist IPV6 To Speed Up Internet Connections
Sep 18, 2009I 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.

View 2 Replies View RelatedFedora Networking :: FC15 IPV6 Wireless Router - No Longer Gets An IPv6 Address
Aug 31, 2011I 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.

Networking :: Use The Laptop With The Wireless Connection To Share The Internet Connection?
Feb 4, 2010I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
View 5 Replies View RelatedUbuntu Networking :: Internet Connection: 'Work Offline' - "No Network Connection"
Oct 31, 2010I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
eth0
Link encap:Ethernet HWaddr 001:aa0:91:a7:51
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisons: 0 txqueulen: 1000
RX bytes: 0 (0.0 B) TX bytes: 0 (0.0 B)
[Code]...
If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.
Ubuntu Security :: Crontab Disabling Internet From 7pm To 7am?
Apr 11, 2010I administer a desktop computer with ubuntu 8.04 in an university library. Since it works almost all night, to enable students to study, after some time I noticed some misuses of the computer during the evening, when there isn't many students. My goal was to disable users from accessing internet from 7pm to 7am, but also enable it if certain user was logged in (I use that user for torrent, and I seed on that computers from time to time). So I created a script that's being called by root's crontab, and here is the script's code:
Code:
#!/bin/bash
NUM=`who|grep myuser|wc -l`
#echo $NUM
if [ $NUM -le 0 ]; then
/sbin/ifconfig eth0 down
else
/sbin/ifconfig eth0 up
fi
Since I created the script, I actually never seeded anything, so I'm wondering now if that's going to work at all, and (also) is there a better solution for this.
Ubuntu Networking :: Wired Networking - Connection Works But No Internet
Jun 1, 2011I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.

OpenSUSE Network :: FTP Connection Returns IPv6 Error
Nov 1, 2010I'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.

Jun 17, 2011OS is Ubuntu 10.04. I have HomePNA-connection which is converted to Ethernet by Netsys NH-300 HomePNA-Ethernet adapter.
The problems that I have: Sometimes when I boot I don't get IP from DHCP. If try to ping any address I am told that host is unreachable. Sometimes this I can get IP by using command dhlient -r and dhclient to request new ip. Sometimes only way to get my connection to work is booting the computer.
Sometimes the connection works fine from the start but disconnects later for short time. Sometimes this happens every ten minutes, sometimes less often. If I wait for a while the connection might start working again, if not dhclient -r or reboot helps usually. But not always.
Fedora Networking :: Wired Networking Not Connecting In 12 With Windows Internet Connection Sharing?
Jan 16, 2011I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
