Help with getting a client to receive a DHCP request

okay..if you are tcpdumping the DHCP traffic to/from your FreeRADIUS box
you should see the outbound response....however, I note that

1) Listening on dhcp interface eth1 address 255.255.255.255 port 67 bound to server dhcp

so the dhcp server is set to listen on eth1.  

what address does eth1 have?


2) I see this in your config "src_ipaddr = 127.0.0.1"  - umm, no. that address is LOCAL,
any network device worth more than 0.01 will not switch that.

3) the result:

Sent code 1026 Id -581776393 from 127.0.0.1:67 to 10.11.12.100:68 length 0 


"Id -581776393" concerns me - looks like some bug.....

however, "from 127.0.0.1:67 to 10.11.12.100:68 length 0 " - I think you'll find no success
because your linux box will not send that out.... even in some self-enclosed VM world, the basics
of networking must still be adhered to.   use proper address that can be switched by the network.
