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)

Hello all,
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)

DHCP6S(8) BSD System Manager's Manual DHCP6S(8)
NAME
dhcp6s -- DHCPv6 server
SYNOPSIS
dhcp6s [-c configfile] [-Ddf] [-k ctlkeyfile] [-p ctlport] [-P pid-file] interface
DESCRIPTION
dhcp6s replies to DHCPv6 client as DHCPv6 server. dhcp6s can give the following information to clients.
o IPv6 prefixes for the requesting site
o Non-temporary IPv6 addresses
o A list of the DNS server addresses
o DNS Domain Search List
o A list of the NTP server addresses
o A list of the SIP server addresses
o SIP Server domain name
o A list of the NIS server addresses
o NIS domain name
o A list of the NIS+ server addresses
o NIS+ domain name
o A list of the BCMCS server addresses
o BCMCS Server domain name
Command line options are as below:
-c configfile
Use configfile as the configuration file.
-d Print debugging messages.
-D Even more debugging information is printed.
-f Foreground mode (useful when debugging). Although dhcp6s usually prints warning, debugging, or error messages to syslog(8), it
prints the messages to standard error if this option is specified.
-k ctlkeyfile
Use ctlkeyfile to store the shared secret to authenticate the communication with dhcp6ctl. The default file name used when unspeci-
fied is /etc/wide-dhcpv6/dhcp6sctlkey. The default name is intentionally same as that for dhcp6ctl so that the server and the con-
trol command can share the file when dhcp6ctl controls the server on the same node, which should be the typical case.
-p ctlport
Use ctlport as the port number listening on to communicate with dhcp6ctl.
-P pid-file
Use pid-file to dump the process ID of dhcp6s.
FILES
/etc/wide-dhcpv6/dhcp6s.conf is the default configuration file.
/var/lib/dhcpv6/dhcp6s_duid is the default file to store the server's DUID.
/etc/wide-dhcpv6/dhcp6sctlkey
is the default key file to communicate with the control command. See dhcp6ctl(8) for the file format.
/var/run/dhcp6s.pid is the default file that contains pid of the currently running dhcp6s.
SEE ALSO
dhcp6s.conf(5), dhcp6ctl(8), dhcp6c(8)
Ralph Droms, Editor, Dynamic Host Configuration Protocol for IPv6 (DHCPv6), RFC 3315, 2003.
HISTORY
The dhcp6s command first appeared in WIDE/KAME IPv6 protocol stack kit.
The -n dnsserv command-line option was obsoleted by introducing a configuration file.
BUGS
dhcp6s is incomplete and violates DHCPv6 protocol spec, in several aspects. To name a few:
1. it does not assign temporary IPv6 addresses (nor will).
