query regarding isc dhcpv6 client and server

Thu Nov 24 06:57:27 UTC 2011

Hi,

Could you provide the dhcpd.conf file contents.

Also I believe you are running the dhclient with the -6 option as

dhclient -6 <interface-name>

Regards,

Vikram

Hi all,

                I need one info about ISC DHCPV6 usage.

                Running server in linux box (RHEL 5.4)

                Server is listening . I got below output in server side

# /usr/sbin/dhcpd -6 -f -cf /etc/dhcp/dhcpd.conf eth1

Internet Systems Consortium DHCP Server 4.1.0

For info, please visit http://www.isc.org/sw/dhcp/

Not searching LDAP since ldap-server, ldap-port and ldap-base-dn were not
specified in the config file

Wrote 0 leases to leases file.

Bound to *:547

Listening on Socket/5/eth1/2001:db8:0:1::/64

Sending on   Socket/5/eth1/2001:db8:0:1::/64

                But the problem is how to start communication with the
client.

                I have connected client and server using cross cables.

                Client is in another linux box.

                While issuning /sbin/dhclient in client side

                Its sending DHCP DISCOVER messages.

                Its not listening the server interface(2001:db8:0:1::/64)

How to start communication.Whether I should change something in client side.

Please tell me what would be the reason.

Please provide solution.

I need the sample output as mentioned below.

I have downloaded dhcp-4.2.3.tar.gz in ISC SITE  and copied to my client
and server.

         Client                                                     DHCP Server
