First of all I would like to thank you as a citizen of the world for offering such professional open source software.
Now my issue I have 2 pc's connected with a cross cable, with connectivity between them using ipv6 both have installed kea 1.2.0 with log4cplus-2.0.0 and openssl writing the leases to a mem file. One of these pc's is designed to be the dhcp server (alias mozo 2001:db8:beef:55::2 or 10.0.0.2) and the other only uses the perfdhcp tool to stress test the dhcp server (alias geek 2001:db8:beef:55::3 or 10.0.0.3). My goal is to establish a statefull dhcpv6 environment. I successfully completed the stress test using perfdhcp with ipv4, but for some reason when i start the ipv6 stress test i get the following result: [root@geek njp]# /opt/kea/sbin/perfdhcp -6 -e address-only -L 546 2001:db8:beef:55::2 Running: perfdhcp -6 -e address-only -L 546 2001:db8:beef:55::2 ***Rate statistics*** Rate: 0 4-way exchanges/second ***Statistics for: SOLICIT-ADVERTISE*** sent packets: 404679 received packets: 0 drops: 404679 Delay summary unavailable! No packets received. ***Statistics for: REQUEST-REPLY*** sent packets: received packets: 0 drops: 0 Delay summary unavailable! No packets received. Server side I ran a dhcpdump and found out that the client (geek) sent the packages and that the server (mozo) is receiving them but the dhcp server does not respond to the clients multiple solicits, example of dhcpdump server side: 19:11:48.300472 IP6 2001:db8:beef:55::3 > ff02::1:ff00:2: ICMP6, neighbor solicitation, who has 2001:db8:beef:55::2, length 32 19:11:48.300531 IP6 2001:db8:beef:55::2 > 2001:db8:beef:55::3: ICMP6, neighbor advertisement, tgt is 2001:db8:beef:55::2, length 32 19:11:48.300621 IP6 2001:db8:beef:55::3.dhcpv6-client > 2001:db8:beef:55::2.dhcpv6-server: dhcp6 solicit 19:11:48.300635 IP6 2001:db8:beef:55::3.dhcpv6-client > 2001:db8:beef:55::2.dhcpv6-server: dhcp6 solicit 19:11:48.300645 IP6 2001:db8:beef:55::3.dhcpv6-client > 2001:db8:beef:55::2.dhcpv6-server: dhcp6 solicit The leases file is empty and the same issue occurs with isc-dhcp-server (dhcpd6). Just in case i disabled ip6tables in both machines and SELinux. Both pc's are running centos 6.9 and the server acts as a RA. I am currently finishing college and this is a crucial part of my thesis, any help in this mater would be greatly appreciated. I can provide the config files via email if you wish.
