have had a problem with my ubuntu system recently in that it will only let me connect to the Internet through Firefox if I switch network.dns.disableIPv6 on. How do I do the equivalent in Ubuntu to enable me to use Ephiphany etc which are not working anymore
View 2 RepliesWhen I go out of town I normally take my Acer Netbook to travel light. I ran into a problem over the weekend which I have seen before and couldn't find the cause. I used the wifi at the house I was staying at and could connect to the router via Wicd and ping outside IP addresses, however, I could not connect to any websites with Iceweasel or Midori. I receive the generic error that the browser is unable to connect. Now that I am back at my house I cannot repeat the problem, but have found a couple threads about disabling ipv6 protocol. The symptoms sound like a browser setting, but I couldn't find any settings that looked unusual.

eth0 Link encap:Ethernet HWaddr 00:0E:7F:4F:E4:09
inet addr:130.130.9.9 Bcast:130.130.255.255 Mask:255.255.0.0

and to do a test i want to disable or delete the ipv6 address, but mainteining the other configured parameters. Looking on the ifcfg config file I have
DEVICE=eth0
BOOTPROTO=static
BROADCAST=130.130.255.255

and nothing about IPv6... Then, using ifdown-ipv6 could i remove only the ipv6 address?
When I run OpenVPN server - tap0 adapter, it breakes Teredo(Miredo) IPv6 address down. I dont need IPv6 on OpenVPN, so is there any way to disable IPv6 on tap0 completely?
View 2 Replies View RelatedI set up a static IPv6 address and a gateway in /etc/network/interfaces. However, a bad router in my network environment alway send wrong ICMP router discovery messages to me. So I have got extra (wrong) IPv6 address and gateway, and the routing is confused. On Windows Servers, I can use "netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disable" to disable ICMP router discovery. But I don't know how to disable it on Ubuntu 9.10. How could I disable ICMP router discovery for IPv6?
View 4 Replies View RelatedNow that IPv6 is becoming more and more common, I found the need to disable IPv6 on some interfaces but have it enabled on other. I found that /proc/sys/net/ipv6/conf/*/disable_ipv6 does exactly that. I am now wondering if anybody knows, why are networking scripts so counterintuitive. /etc/sysconfig/network has an option:
NETWORKING_IPV6=yes
All this option does is disable some ipv6 services (dhcpv6...), it does not disable IPv6 in whole (as one would assume...that's why you had to disable it with module parameters). Searching for more IP6 related config option, one can find that /etc/sysconfig/network-scripts/ifcfg-* scripts can contain:
IPV6INIT=yes
Again, this option does not disable IPv6 protocol on the interface, it just skips running ifup-ipv6/ifdown-ipv6 scripts. I added a /sbin/ifup-pre-local. Now, this script runs before ethX entries are created (other scripts run when it's already too late) in /proc directory, so it modifies default values which are then used after those entries are created:
#!/bin/bash
#
[ -f "/etc/sysconfig/network-scripts/$1" ] && . /etc/sysconfig/network-scripts/$1

I cannot connect to wirelessly when I have IPv6 enabled for the wireless network card. It works great on ethernet, but if I enable it for the wireless card then I cannot even get IPv4.
View 5 Replies View RelatedThe 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?
I used to play with gw6c ( a client for tunnel broker ) It works well with fedora9 , fedora 10, but not with leonidas. my rpm is gw6c-6.0-0.4.beta4.fc9.i386.rpm ( a little old!) when I tried to install i have got this: libcrypto.so.7 est ncessaire pou w6c-6.0-0.4.beta4.fc9.i386 I try to make a soft link to libcrypto.so.0.9.8k, but nothing; The question :-Is there a solution for that pb - did you know a better client for non native ipv6 connectivity?
View 2 Replies View RelatedI 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.
Okay so on WebUpd8 website, (url), I found a way to disable IPv6 and I was hoping to get a little more of an understanding of if I should or not from comments there, but unfortunately I haven't gotten enough to say let's do that. So I figured I might get a better understanding on here.
I am not very familiar with IPv6, but to my understanding its a newer thing that's rarely found currently with ISPs, but can be a security issue now.
Anyone know how to disable IPv6 but still use IPv4?
View 6 Replies View RelatedI 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.
I am experiencing very slow internet speed while downloading files from internet. Although torrent (KTorrent) download speeds are okay. I am using 'rekonq' Web Browser. Konqueror is slower than this and Firefox is the slowest. Thats why I have uninstalled Firefox from my Suse 11.3 KDE. I went through the guides mentioned here:
Disable IPv6 But the images shown here in the first post (by caf4926) [URL] have slightly different configuration from my computer. (My account does not allow me to post attachments). In the pic 2, Do we have to select the option: "User Controlled with NetworkManager" before unchecking the Enable IPv6 option.

does opensuse 11.2 come with IPv6 enabled by default? where in the gnome gui can i access these settings?
Edit-i went into the gnome network manager applet and i cant find any IPv6 settings for any of my used connections-ethernet, wireless and VPN connections all seem to only IPv4. Can anyone else confirm that opensuse 11.2 uses only IPv4 on its network connections?
I just finished setting up my slack machine as a home server (printers & files) and I noticed that I have an IPv6 address (from ifconfig)... I didn't know I did. I used to work in tech support and when a windows or OSx machine didn't connect properly on a LAN, disabling IPV6 was a common troubleshooting step. Is there a way to easily turn inet6 connectivity off/on in Slackware? (I want to keep the ability to get an IPv6, we will all use those in the future)

I'm running Ubuntu in VMWare for a side project. I noticed when I boot up, it doesn't let me access anything externally. I have to disable network manager and re-enable it. Once done, I can hit everything fine. I'm using a static IP in network manager.
View 1 Replies View RelatedSupport for ipv6 keeps being put into the kernel and now into browsers.I blacklisted ipv6 in Slackware and that solved the slow internet response until I updated to the latest Opera and Firefox browsers. Both were horribly slow again. Firefox could be reconfigured to kill ipv6 by running about:config as a url and disabling ipv6.
The new Opera 11 is different. I can't find any config to disable ipv6. Does anyone have an idea?I reverted to Opera 10.11 in order to have zippy internet access again, and not "dialup modem" speeds.
i installed ubuntu using wubi, and every time i open firefox it says it cant connect to ubuntu server.

When I'm trying to access my site using Firefox I get this error: "Unable to connect
Firefox can't establish a connection to the server at mysite.com.
-The site could be temporarily unavailable or too busy. Try again in a few moments.
-If you are unable to load any pages, check your computer's network connection.
-If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."
Then I tried to access my site using Opera and Chrome but I get the same error, that the browsers couldn't connect to it.
The site to which I'm trying to connect is definitely up. (I ask a few people and they can access it and I looked at [url] and it says that my site it's up)
In all but one place my HP Pavilion laptop running Fedora 14 will work flawlessly to use the Internet for e-mail, ftp, http, etc. In one network there is a wireless router - Cisco/Linksys E3000 - that allows every computer to use the Internet normally for wireless or for wired connections, every computer but mine. If I use Google's Chrome I can access the Internet. I can ping any web site too, but the moment I try to access anything with Firefox 3.6.17 there is a long delay and the standard error page appears. Weather or not I use a wired connection is apparently irrelevant.The Windows 7 computers in the same network are free of this curious problem. Strangely I have noted a problem like this, possibly the same problem, with another network at a coffee shop and they both share the misfortune of using AT&T, which is proud to not support Linux ... for customers of course (it's good enough for themselves I'm sure)
