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

...

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


Hi,

I think the easiest way how to get working dhcp-4.1.x on RHEL-5 is to recompile my source rpm [1]:

- download http://jpopelka.fedorapeople.org/dhcp-4.1.2-5.ESV.R3.el5.src.rpm
- yum install rpm-build
- rpmbuild --rebuild dhcp-4.1.2-5.ESV.R3.el5.src.rpm
- install RPMs from /usr/src/redhat/RPMS/<arch>/

Then you would probably need to:
- allow dhcpv6 ports in firewall, i.e. 546 for client and 547 for server. For testing purposes you could also turn whole firewall off with 'service ip6tables stop'
- Do what Scott already suggested, i.e.
  - switch SELinux to permissive mode (as already suggested)
  - specify interface when running dhclient
