Hi, after multiple recompilation of FR (both version 2.2 and 3.0.1) i was not able to configure DHCP server so that clients would get IPs. I am currently testing on ubuntu 12.04.3 server which has connected Ubuntu 12.04 desktop version laptop on eth1 trying to get IP. I see multiple requests comming to server but no reply reaches the client (nor ethernet card). FR is built from source and following this configuration http://wiki.freeradius.org/guide/dhcp-for-static-ip-allocation (with exception of using mac2ip for IP filetable). Here is relevant info on server: eth1: inet addr:192.168.0.1 dhcp config: server dhcp { listen { ipaddr = 255.255.255.255 port = 67 type = dhcp interface = eth1 dhcp DHCP-Discover { update reply { DHCP-Message-Type = DHCP-Offer } # The contents here are invented. Change them! update reply { DHCP-Domain-Name-Server = 192.168.0.1 DHCP-Domain-Name-Server = 193.2.1.66 DHCP-Subnet-Mask = 255.255.255.0 DHCP-Router-Address = 192.168.0.1 DHCP-IP-Address-Lease-Time = 86400 DHCP-DHCP-Server-Identifier = 192.168.0.1 } mac2ip ok } dhcp DHCP-Request { update reply { DHCP-Message-Type = DHCP-Ack } # The contents here are invented. Change them! update reply { DHCP-Domain-Name-Server = 192.168.0.1 DHCP-Domain-Name-Server = 193.2.1.66 DHCP-Subnet-Mask = 255.255.255.0 DHCP-Router-Address = 192.168.0.1 DHCP-IP-Address-Lease-Time = 86400 DHCP-DHCP-Server-Identifier = 192.168.0.1 } mac2ip ok } dhcp { # send a DHCP NAK. reject } } radiusd -X output is here: http://pastebin.com/raw.php?i=yY1aNf6v i have used tcpdump to check port 67 and 68, but only requests come in, no reply is released to ethernet card. Any suggestions? Regards, Rok
