I have tried to disable the ipv6 support in ubuntu 9.04 32bit but the /etc/modprobe.d/aliases does not exist so I can't disable the suport as sugested for the previews versions. I need to disable it becouse it is pounding a total maihem in my vamware machines.
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
I 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?
Now 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:
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:
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:
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?
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.
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.
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 have installed bind with yum install bind bind-chroot.I am having query timeouts due to no ipv6 connectivity.Is there a way to re-compile and not loose the chroot structure?Or is there another way to disable ipv6 lookups?Example of issue resulting in ipv4 query timeout:
30-Dec-2010 17:52:03.226 client x.x.x.x#53593: view internal: query: paypal.com.cms.local IN A + 30-Dec-2010 17:52:03.227 client x.x.x.x#53594: view internal: query: paypal.com.cms.local IN AAAA + 30-Dec-2010 17:52:03.228 client x.x.x.x#53595: view internal: query: paypal.com IN A +
When 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.
I have Ubuntu 10.10 installed on my laptop. My ISP natively supports ipv6, but since last weekend, I do not get an ipv6 ip. When I use a live cd however, I do get an ipv6 ip. For as far as I can see, all settings (/etc/network/interface and the settings in network manager) are exactly the same.
Output of ifconfig:
Code: eth0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX inet addr:XXX.XXX.XXX.XXX Bcast:XXX.XXX.XXX.XXX Mask:XXX.XXX.XXX.XXX inet6 addr: XXXX::XXXX:XXXX:XXXX:XXXX/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
EDIT: is there a way to let the netwerk be automatically configured as happens during installation? It would be nice to start with a clean and new set of network config files as there were just after I installed Ubuntu on my system, without a full reinstall of my system.
I have a networking problem with my computer. Under Windows, the computer can get both v4 and v6 address via DHCP. However, the same computer can only get v4 address under Ubuntu. Does anybody know how to solve this problem?
some of you might have experienced the network speed problem that occurs when ipv6 is enabled. So have I. I know about the common workaround of disabling ipv6, but recently I tested the new ubuntu live system, and the problem was gone with ipv6 being enabled.
Now my question is: Do you know what ubuntu is making different? I haven't found an explanation. Is there a better workaround than blacklisting ipv6?
I'm trying to assign like 80 IPv6 addresses on eth0 for virtual webhosting, but after 55 addresses I get the following error:# ip addr add 2a01:9f8:a171:1651::4b:a8af dev eth0 RTNETLINK answers: File exists.What's the problem? I don't understand that error message at all. Is the number of IPv6 addresses per device somehow limited?Ubuntu 10.4.1 server, 64 bit.
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've just started using ufw with the frontend gufw. I've configured it like this:
Accept everything in and out as default Block incoming FTP connections from a certain IPv4 address (brute-force for days)
Today I noticed that IPv6 connections don't work anymore. The connection to two hosts (IPv6 only) times out. As soon as I disable ufw entirely, the connections work again. The host I want to connect to is:
2001:638:a00:f00b:200:1cff:fedb:d38f port 7337 2001:638:a00:f00b:a00:6ff:fe07:cda2 port 7337
These are small telnet servers that print out a number (temperature nearby) and close again. I'm logging those values in a database.
Is ufw not IPv6-capable and blocks things it's not supposed to?
Update: ufw seems complete garbage to me... You can't even configure it while it's disabled! How am I supposed to safely activate it when the first thing it does is blocking all communications? I can't even configure it to let me in before I configure it to keep me out... And then, even if I explicitly let it pass port 7337, it still blocks it through IPv6.
I've been using IPv6 on my local network and through a Hurricane Electric IPv6 tunnel. I've heard that one of the built in features of IPv6 is encryption, both scrambling the data and authenticating where the traffic came from. I've done some searching and heard of SWAN and Racoon, but some of the stuff I found is old and I would like to know what the easiest/best way to set up IPSEC for IPv6 is.
Anyone who's interested in playing with IPv6 should be able to do so using '6to4' - even if you're behind a NAT device! The following steps works for me on Ubuntu 11.04 (taken[URL].. 1. Make sure the 'iproute' package is installed:
Quote: $ sudo apt-get install iproute 2. Calculate your 6to4 address: Quote: $ ipv4="18.104.22.168"; printf "2002:%02x%02x:%02x%02x::1" `echo $ipv4 | tr "." " "` 2002:4a7d:ed31::1 (Replace 22.214.171.124 with the public IPv4 address assigned to you by your ISP)
I have a problem with my ipv6 connection: although I can't get ipv6 address with DHCP, I can't use ipv6 network. I tried [URL], and the tortoise is static. I want to fix it out , so I use 'ifconfig' to see my network configuration:
Some people told me that the fisrt ipv6 address was wrong and unsuitable for ipv6 connecting. I tried /ect/init.d/networking restart but it didn't work. How can I use the second address as my ipv6 address and fix the problem out ? Now it seems there is not problem with the ip adress but the route. After watching some video, I suddenly could use ipv6. I did 'ifconfig' again and nothing was different. However, the result from the command 'ip -f inet6 route' changed: the last default route was gone and there was only one default route.
