Dhcpv6 Problem

[marcinps]

Witam otóż mam taki problem Zainstalowalem na wirtualnych maszynach 2 systemy fedora 8(HostA i HostB). Pociagalem yum-em dhcpv6 na obu systemach, gdyz chce uzyskac na systemie klienckim Host B adres z servera DHCPv6 (Host A).

 

Ponizej przedstawiam konfiguracje servera DHCPv6 (Hosta A):

Nie dostaje adresu z servera DHCPv6 na kliencie.

Oba systemy sie widza Dochodzi ping6 z obus sytemow.

Co mam zrobic aby to zadziałało???Bardzo prosze o pomoc.

 

[marcinps]

Udało sie U mnie problem byl akurat z identyfikatorem DUID, ktory jest w katalogu /etc/var/lib/dhcpv6/ serwera i klienta.

Poprostu wywalilem go w serwerze i kliencie i uruchomilem ponownie serwer DHCPv6.Identyfiaktor wygenerowal sie na nowo i bylo oki. Przy tworzeniu DHCPv6 korzystalem z nast polecen (moze kiedy sie komus to przyda):

 

yum install dhcpv6

Server:

1)

File : /etc/sysconfig/dhcp6s

 

DHCP6SIF=eth0

2)

File : /etc/dhcp6s.conf

 

interface eth0 {

server-preference 255;

renew-time 60;

rebind-time 90;

prefer-life-time 130;

valid-life-time 200;

allow rapid-commit;

link BBB {

pool{

range 2001:0E30:1402:2::4 to 2001:0E30:1402:2::ffff/64;

prefix 2001:0E30:1402::/48;

};

};

};

 

3) #service dhcp6s start

 

 

Client:

1)

File : /etc/sysconfig/network-scripts/ifcfg-eth0

IPV6INIT=yes

DHCP6C=yes

2)

File : /etc/dhcp6c.conf

interface eth0 {

#information-only;

send rapid-commit;

#request prefix-delegation;

#request temp-address;

address {

2001:0E30:1402:1:9656:3:4:56/64;

 

};

 

};

 

3)

Start the server daemon in debug mode in foreground

#dhcp6s –dDf eth0

 

4)

Restart the network service of client

#service network restart

 

5)

#ifconfig

 

Tylko zawsze jak uruchomie wirtualne maszyny to musze te DUID-y kasowac No ale jakos zadzialalo.
