When I do simple nslookup it does not generate any query for IPV6 (AAAA). But sometimes I see DNS query for both A and AAAA are generated. What decides this? The reason I do not want AAAA query is in most of the cases AAAA records are absent. Hence, if one DNS server fails, the clients keeps... (1 Reply)

I want to find out the DHCPv6 server's ip address in the network. I went through the lease files but could find only duid/server-id and not the IPv6 address of the dhcp server. And I couldn't find any commands to get that information. Is there a way to get the DHCPv6 server's IPv6 address?

I am trying to receive (tcp/udp/sctp) traffic from all IPs and, eventually, all ports of an IPv6 address block using as few sockets as possible short of implementing my own network stack.
One possible solution was to associate an IP block to an interface then bind to that... (6 Replies)

FAITH(4) BSD Kernel Interfaces Manual FAITH(4)
faith -- IPv6-to-IPv4 TCP relay capturing interface
The faith interface captures IPv6 TCP traffic, for implementing userland IPv6-to-IPv4 TCP relay like faithd(8).
Each faith interface is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or using
the cloned_interfaces variable in rc.conf(5).
Special action will be taken when IPv6 TCP traffic is seen on a router, and the routing table suggests to route it to the faith interface.
In this case, the packet will be accepted by the router, regardless of the list of IPv6 interface addresses assigned to the router. The
packet will be captured by an IPv6 TCP socket, if it has the IN6P_FAITH flag turned on and matching address/port pairs. As a result, faith
will let you capture IPv6 TCP traffic to some specific destination addresses. Userland programs, such as faithd(8) can use this behavior to
relay IPv6 TCP traffic to IPv4 TCP traffic. The program can accept some specific IPv6 TCP traffic, perform getsockname(2) to get the IPv6
destination address specified by the client, and perform application-specific address mapping to relay IPv6 TCP to IPv4 TCP.
The IN6P_FAITH flag on a IPv6 TCP socket can be set by using setsockopt(2), with level IPPROTO_IPV6 and optname IPv6_FAITH.
To handle error reports by ICMPv6, some ICMPv6 packets routed to an faith interface will be delivered to IPv6 TCP, as well.
To understand how faith can be used, take a look at the source code of faithd(8).
As the faith interface implements potentially dangerous operations, great care must be taken when configuring it. To avoid possible misuse,
the sysctl(8) variable net.inet6.ip6.keepfaith must be set to 1 prior to using the interface. When net.inet6.ip6.keepfaith is 0, no packets
will be captured by the faith interface.
The faith interface is intended to be used on routers, not on hosts.
