Even if it is unable to contact the originating DHCPv6 server, it will configure the address. This behavior is in compliance with RFC , section The DHCPv6 client is installed by default. Not all DHCPv6 servers support rapid-commit. To display DHCPv6 configuration data, use the dhcpinfo 1 command, with the "-v6" option.
For example, to display the DNS servers returned by the server, run:. This will set the request options globally. To set them for a specific interface, prepend the interface name to the line, e. Upon reboot, if the lease is still valid, Solaris will reconfigure that address, even if the DHCPv6 server that leased it is offline.
If it doesn't get a response, it will configure the address anyway. When installed as a service, Dibbler does not run before the logon window appears. There is a several second delay before the DHCPv6 reply is received. It tries to renews its address when half of the preferred lifetime has elapsed e. By default, Ubuntu's DHCPv6 config runs in information-only mode - it assumes it gets a routable IPv6 address via stateless autoconfiguration.
Ubuntu's dhcp6c-script will set DNS servers and search domains. It does not set NTP servers. The WIDE dhcp6c client appends ". However, selecting this box doesn't actually do anything. The DHCPv6 client dhcp6c will not be enabled after installation. You must manually specify what options to request in dhclient. Currently, there is very little documentation on DHCPv6 configuration. Users are advised to consult ISC's dhcp-users mailing list.
If you do mind, read on. Windows 7 and Server R2 had IPv6 enabled by default. No action is required to enable IPv6.
Internet Connection Sharing ICS is disabled by default, and should be disabled if found to be enabled on any network interface as described here. They also had a DHCPv6 client enabled by default. This may or may not be considered acceptable. The following command lines will disable some vulnerable IPv6 interfaces that are enabled by default. Their use is not required, but is recommended for better security. It is also possible to disable these vulnerable interfaces using Group Policy Objects GPO as described in this article.
It is not recommended that you leave the Teredo protocol enabled, but if for some reason you want to, omit that last line. You will likely also want to configure your own Teredo server since the old default Teredo servers configured with a command such as. If the computer you are configuring is part of a Windows domain, the command.
It is not recommended to enable Teredo when connected to a Windows domain. The first two command lines delete a temporary randomly-generated global IPv6 address Windows creates but which is neither useful nor desirable when you have a real global IPv6 address. Whenever a mobile system moves to a different network, or whenever the network the system is connected to is renumbered, these commands must be reentered.
To verify this, run the commands. These are also documented on the Microsoft web site look at the Microsoft knowledge base article KB article for more details. It is also strongly recommended to check the status of ICS and disable it wherever it is enabled, following the guidance provided by the University of Delaware here. It is possible to re-enable IPv6 after it has been disabled using either of the following two methods depending on how it was disabled :.
How do I debug this issue further. I have capture wireshark logs and them seem normal in terms of packet consistency. I have not dissected them further to check if there is anything wrong in the packets.
There are errors that are harmless. I would inspect the Advanced parameters in Network Connection Properties. When the error message appears, it will most likely halt the operation of the application because the required parameter needed to load the file is insufficient. There may be some setting problem in your Windows 7 host. You can refer to the link below for some reference. It is not a domain controller. A linux based device, that is executing a DHCPv6 server.
My win 7 P. C does not receive IPv6 address in this case even after long duration. But this is not always the case.
