If I add a "pre-up sleep 10" to the interfaces file and reboot the system it gets a dhcp6 provided address along with an autocofiguration ipv6 address.
This doesn't seem to be the way it should work. August 4th, 5. Re: How to configure network for dhcpv6 address I should also mention that dhclient is providing the fqdn to dhcpv4 and that's working just fine. August 5th, 6. Re: How to configure network for dhcpv6 address It looks like there is a fix applied to debian that hasn't made it's way to ubuntu as of today. Bookmarks Bookmarks Digg del. The time now is PM.

It only takes a minute to sign up. The client has Ubuntu However, that does not happen. I suspect the routers has the wrong advertising flags set. But I can't configure the router as it is provided by the ISP. What can I do? Are there any suggestions? In addition we assume your router has two network interfaces: eth0 uplink to ISP and wlan0 for clients.
Configure DHCP client on Ubuntu
If you now configure your DHCPv6 server the following:. In addition you should start the server with some debugging output to test whether requests are arriving from the client. For ISC dhcpd you can use the "-d -f" options, e. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. Asked 4 years, 8 months ago.
DHCPv6: Provide IPv6 information in your local network
Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. We're talking about a Linux Box running as Router using Ubuntu I am able to successfully connect to my ISP. I get no reply. However, router advertisements are working, both on "ppp0" and on my internal lan, because I have a Default Route: "default via fe" when I "ip -6 r".
However, no global IPv6 address. I want the same Host-part allocation using " ", " ", and so on Either one may be omitted. The identifier must be specified in standard ascii notation of IPv6 addresses e. If the ipv6cp-use-ipaddr option is given, the local identifier is the local IPv4 address see above. On systems which supports a unique persistent id, such as EUI derived from the Ethernet MAC address, ipv6cp-use-persistent option can be used to replace the ipv6option.
Otherwise the identifier is randomized.
So if you used ipv6would that do what you wanted? As an experiment you can replace ipv6cp-use-ipaddr with ipv6cp-use-persistent instead From there you can start tweaking your wide-dhcpv6 and radvd Ubuntu Community Ask!

I have a strange situation here. If anyone can help, please do so. My problem is that I cannot get IPv6 global address on this server. The problem is that I tried more configs from the net, non of them worked for me.
When I "ifconfig ppp0", it says: inet 1.
I suspect it something to do with DHCP. The address is not obtained correcly. But when trying to "ping6 google.Computers configured to be DHCP clients have no control over the settings they receive from the DHCP server, and the configuration is transparent to the computer's user. By default it listens to eth0. Also, you have to assign a static ip to the interface that you will use for dhcp.
If you will use eth0 for providing addresses in the Without this step you will get an error from dhcpd when starting the service. Configuration The error message the installation ends with might be a little confusing, but the following steps will help you configure the service: Most commonly, what you want to do is assign an IP address randomly. It will lease an IP address for seconds if the client doesn't ask for a specific time frame.
Otherwise the maximum allowed lease will be seconds. The server will also "advise" the client that it should use If you need to specify a WINS server for your Windows clients, you will need to include the netbios-name-servers option, e.

Page History Login to edit.The various Linux distributions configure DHCPv6 in a variety of ways because they use different packages. No additional changes are required when you use these images.
By improperly editing network configuration files, you can lose network access to your VM. We recommended that you test your configuration changes on non-production systems. The instructions in this article have been tested on the latest versions of the Linux images in the Azure Marketplace.
Dynamic Host Configuration Protocol (DHCP)
For more detailed instructions, consult the documentation for your own version of Linux. On Ubuntu Beginning with Ubuntu Please include a dhcp6:true statement for each ethernet interface in your configuration. For example:. You may also leave feedback directly on GitHub.

Piece of advice : This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system.
Okay, after setting up the configuration of your local system, it might be interesting to enable all your machines in your network to use IPv6.
There are two options to solve this kind of requirement Either you're busy like a bee and you go around to configure each and every system manually, or you're more the lazy and effective type of network administrator and you prefer to work with Dynamic Host Configuration Protocol DHCP.
Obviously, I'm of the second type. In case of Ubuntu-based installation this might be isc-dhcp-server. The isc-dhcp-server allows address pooling for IP and IPv6 within the same package, you just have to run to independent daemons for each protocol version.DHCP for IPv6
First, check whether isc-dhcp-server is already installed and maybe running your machine like so:. This file is not automatically provided by the package, compared to IPv4.
Again, use your favourite editor and put the following lines:. Next, save the file and start the daemon as a foreground process to see whether it is going to listen to requests or not, like so:. You might also use the command switch -t to test the configuration file prior to running the server. In my case, I ended up with a couple of complaints by the server, especially reporting that the necessary lease file wouldn't exist.
So, ensure that the lease file for your IPv6 address assignments is present:. Now, you should be good to go. Stop your foreground process and try to run the DHCPv6 server as a service on your system:. Refer to the man-pages of isc-dhcp-server and you might check out Chapter But see for yourself. Running a DHCPv6 server on your local network surely comes in handy but it has to work properly. The following paragraphs describe briefly how to check the IPv6 configuration of your clients.
Note : Your network device might be eth0 - please don't just copy my configuration lines. Then, either restart your network subsystem, or enable the device manually using the dhclient command with IPv6 switch, like so:. You would either use the ifconfig or if installed the ip command to check the configuration of your network device like so:.
Looks good, the client has an IPv6 assignment.
