Hi,<br>
<br>
I think the easiest way how to get working dhcp-4.1.x on RHEL-5 is to recompile my source rpm [1]:<br>
<br>
- download <a href="http://jpopelka.fedorapeople.org/dhcp-4.1.2-5.ESV.R3.el5.src.rpm">
http://jpopelka.fedorapeople.org/dhcp-4.1.2-5.ESV.R3.el5.src.rpm</a><br>
- yum install rpm-build<br>
- rpmbuild --rebuild dhcp-4.1.2-5.ESV.R3.el5.src.rpm<br>
- install RPMs from /usr/src/redhat/RPMS/<arch>/<br>
<br>
Then you would probably need to:<br>
- 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'<br>
- Do what Scott already suggested, i.e. <br>
- switch SELinux to permissive mode (as already suggested)<br>
- specify interface when running dhclient<br>
