ISC dhcp in RHEL5 does not support IPv6
Last modified: 2012-10-24 08:46:27 EDT
Description of problem: ISC dhclient does not support IPv6 either. RHEL 5 contains package dhcpv6, but this client does not support setting up a DUID type. It automaticaly generates some incorrect type of DUID-LLT which is unpredictable and is very hard to copy from a console of IPv6 only host yet without network to the dhcpd6.conf of server. As dhcpv6 is now obsolete, I am filling this bug for dhcp. It would be fine to have a reasonable DHCPv6 client on RHEL5 and I think that a newer version of ISC dhcp will do it very well. Version-Release number of selected component (if applicable): Name : dhcp Arch : x86_64 Epoch : 12 Version : 3.0.5 Release : 31.el5_8.1 Name : dhcpv6 Arch : x86_64 Version : 1.0.10 Release : 20.el5 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: DHCPv6 is supported only by obsolete client which is not full featured. Expected results: DHCPv6 should be supported by full featured client. Additional info:
Thank you for the report, however there's no way we can rebase ISC dhcp to 4.x in RHEL-5. dhcpv6 has been obsoleted upstream (few years ago) but we still support it in RHEL-5. You can fill a new bug against dhcpv6 component and describe the DUID related problem you see. Thanks. Closing this one as WONTFIX.
I forgot to add that ISC dhcp in RHEL-6 is IPv6 Ready (http://www.ipv6ready.org) so your another possibility is RHEL-6.
