Hi,
I'm having problems to configure the dhcp with freeradius (this is the
first time :$)
I have compiled it with the --with-dhcp option, and linked dhcp in
sites-available.

My dhcp server is 10.88.3.25 and the router is 10.88.3.1.

I have only modified the dhcp configuration and the mac2ip file.

This is the dhcp configuration:
______________________________________________
server dhcp {

listen {
        ipaddr = *
        port = 67
        type = "dhcp"   
        interface = eth0
}

dhcp DHCP-Discover {
        update reply {
               DHCP-Message-Type = DHCP-Offer
        }

        update reply {
                DHCP-Domain-Name-Server = 80.58.0.33
                DHCP-Domain-Name-Server = 80.58.0.33
                DHCP-Subnet-Mask = 255.255.255.0
                DHCP-Router-Address = 10.88.3.1
                DHCP-IP-Address-Lease-Time = 86400
                DHCP-DHCP-Server-Identifier = 10.88.3.25
        }

        mac2ip
        ok
}

dhcp DHCP-Request {
        update reply {
               DHCP-Message-Type = DHCP-Ack
        }

        update reply {
                DHCP-Domain-Name-Server = 80.58.0.33
                DHCP-Domain-Name-Server = 80.58.0.33
                DHCP-Subnet-Mask = 255.255.255.0
                DHCP-Router-Address = 10.88.3.1
                DHCP-IP-Address-Lease-Time = 86400
                DHCP-DHCP-Server-Identifier = 10.88.3.25
                DHCP-Gateway-IP-Address = 10.88.3.1
        }

        mac2ip

        ok
}

dhcp {
        # send a DHCP NAK.
        reject
}

}
_________________________________________________

I put the mac adress in mac2ip and it works, here is the file:
fa:b3:77:de:25:6b,10.88.3.20

When I launch it in debug mode I have this exit:

Error on call sendmsg: Invalid argument
errno = 22.
_____________________________________________________

It looks like it's sending the dhcp response but with tcpdump I can't
see anything (of the response), the I decided to see the code and went
to the call sendmsg in src/lib/udpfromto.c
and change this:
<<
return sendmsg(s, &msgh, flags);
<<
>>
int res = sendmsg(s, &msgh, flags);
        if (res == -1){
        perror("Error on call sendmsg");
        printf("errno = %d. \n", errno);
        exit(1);
}

return res;
>>

I think its something of the configuration.

I someone can help me I'll be really grateful.

Sorry for my english :D

Jewi.
