I have just installed Kubuntu 9.4 and my wifi will not work. dmesg tell me it is looking for IPv6 and my router does not support it.
how I can tell the OS to ignore IPv6 and use IPv4?
I have read writing alias net-pf-10 off; and alias ipv6 off in /etc/modprobe.d/alias is supposed to work but Kubuntu 9.4 does not have an alias file in modprobe.d
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.
I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
My router doesn't support IPv6. I'm wondering could IPv6 support be provided by just upgrading the firmware? I thought it was just a protocol. Also how does not having IPv6 support affect home users?
View 3 Replies View RelatedI decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:
Feb 8 17:55:17 foo kernel: [ 1344.824474] Dead loop on virtual device tun6to4, fix it urgently!
my local clients connected to the IPv6 internet.
I've already designated a machine to act as the router to the hurricane electric tunnel. I created a he-ipv6 device on it and can ping ipv6.google.com. No problem.
The problem happens when I want clients to use that router. That is, I can't ping ipv6.google.com from other machines on my LAN.
I setup /etc/radvd.conf, which seemed to successfully give out addresses to my clients:
interface eth0
{
AdvSendAdvert on;
prefix MY:HEREFIX::/64
[Code]....
I start the daemon and check that my clients have new ip6 addresses. So far so good. On my router, I do a sysctl -p and see that /proc/sys/net/ipv6/conf/all/forwarding = 1. I haven't touched ip6tables/iptables yet. Both are in a flushed state.
My ipv6 router is actually inside the LAN which gets internet from another machine which has let ipv6 packets through using protocol 41. I figure I don't have to worry about anything else because if my router can ping6 ipv6.google.com, the failure point would be there.
So my clients get ip6 addresses, but can't ping6 the router nor the ipv6.google.com. They do resolve ipv6.google.com however and I checked the traffic on the router over he-ipv6 from ifconfig and RX and TX bytes were changing during the ping.
My router has only one physical device for forwarding, eth0 and the tunnel device he-ipv6. Do I need to add some kind of ip6tables to see a simple ping from my clients?
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?

View 9 Replies View RelatedI have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?
Here is a link to (picture) my network diagram. Network Diagram
These r IP provided by my ISP that i've put on Fedora 8:

i want to run xxx.xxx.xxx.147 as a web server & xxx.xxx.xxx.148 as a ftp server. but I'm able to ping only xxx.xxx.xxx.17(WAN IP) from outside world. Can any1 tell me that how can i bring my 147 & 148 IP online without router.
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.

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 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.
I have installed Bind 9.6.1 on my linux pc. I have to resolve domain name using IPv6 address. I have made following entry in the /etc/resolv.conf file code...
address of the machine on which Bind is running. The problem is that I am not able to ping open-ims.test domain name. If I use IPv4, everything works fine but how to ping domain using IPv6.
I have also made changes in dnszone file by replacing IPv4 address with IPv6 address and also changing A to AAAA.
I want to add repository using ipv6. So, I add a xxx.repo file in /etc/yum.repos.d/. Just like it:
[sjtu6]
name=Fedora $releasever - $basearch - ftp6.xxx.xxx.xxx
baseurl=ftp://ftp6.xxx.xxx.xxx/fedora/releases/$releasever/Everything/$basearch/os/

Let's start with my external box. It is headless debian lenny dhcp/local-dns & cache/firewall. It has the following interfaces after a reboot:

My understanding is that ipv6 will auto-configure itself and that the radvd file is all that is needed by the external host to give all the ipv6 enabled internal hosts ipv6 web access. My question: How is my external host misconfigured? Or are the problems specific to the internal hosts? I am assuming that I have issues on both the external and internal hosts since some of the internals have golobal ipv6 address and some don't. I do however wish to address the external host first.
I have a host and typing ifconfig I get:
eth0 Link encap:Ethernet HWaddr 00:0E:7F:4F:E4:09

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?

View 2 Replies View RelatedI've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.
