Hi listers,

This drives me crazy. I try to net boot a 600au via bootp from a dhcp 
server on a linux machine (actually a i386 w/ linux/SuSE 9.3). The 
dhcpd.conf file has:

ddns-update-style none;
authoritative ;
allow bootp;
log-facility local0;
deny unknown-clients;
default-lease-time 14400;
subnet netmask {
   option subnet-mask;
   option broadcast-address;
   option routers;
   option domain-name-servers ns0, ns1;
   option domain-name "mydomain";
   default-lease-time 14400;
   max-lease-time 43200;

host PWS_600au {
   # option tftp-server-name "myserver";
   option host-name "alphab" ;
   # option root-path "/opt/tftp/boot/NetBSD/2.1/alpha" ;
   # allow booting;
   hardware ethernet 08:00:2b:86:8c:ae;
   #server-name "myserver" ;
   # next-server myserver ;
   # next-server ;
   # filename "/boot/NetBSD/2.1/alpha/net.boot";
   option bootfile-name "/opt/tftp/net.boot";
   # filename "boot/netbsd";
   always-reply-rfc1048 true;

files mentioned above do exist and are retrievable by tftp (checked from 
a working system. hostnames resolve to a ip address. MAC address matches.

On linux I see
$> tcpdump -i eth0 -s 400 -vv dst port bootps or dst port bootpc \
    or dst port tftp

21:18:46.941841 IP (tos 0x0, ttl  32, id 4209, offset 0, flags [none], 
length: 328) > [udp sum ok]

           Your IP: alphab
           Server IP: myserver
           Client Ethernet Address: 08:00:2b:86:8c:ae

tcpdump doesn't even show a request to the tftp port.

The SRM shows:
Sending BOOTP packet
..file open failed for ewa0/

and again, and again ...

I have tried many combinations as seen by commented out options in the 
dhcpd.conf. But the 600au doesn't like to boot. What am I doing wrong?
