Summary | 0001149: pfdhcplistener not properly updating iplog when configured with ip-helpers aka pfdhcplistener should update iplog on DHCP INFORM | |||||||
Description | We realized that pfdhcplistener only updates iplog on server replies. In an ip-helper address based setup, such replies will never reach the packetfence server since they are unicast packets going back to the ip-helper enabled switch. Updating internal iplog database on DHCP INFORM packets will fix the problem. It's an important enough problem that for those not ready to upgrade, a simple patch will be provided here that should apply cleanly to 1.8.x, 1.9.x. | |||||||

pfdhcplistener now updates iplog when processing DHCP INFORM packets |
(0001801) obilodeau (reporter) 2011-01-10 17:01 |
Attached patch should apply cleanly to most packetfence installations. Apply from /usr/local/pf with: patch -p1 < pfdhcplistener-updates-iplog-on-inform.patch |
(0001805) obilodeau (reporter) 2011-01-12 12:35 |
apparently some devices don't send DHCP INFORM at the end of their DHCP handshake so we need to find another way |
(0001806) obilodeau (reporter) 2011-01-12 15:03 |
After reading RFC 2131, we should use DHCP REQUEST instead of DHCP INFORM as our source of updated client IP information. |
(0001807) obilodeau (reporter) 2011-01-12 15:28 |
Fixed for good. Updated attached patch that should apply cleanly on 1.9.x, 2.0.0 and maybe 1.8.x. |
