Re: FreeBSD PXE client not getting netmask config from DHCP server
Hello Erik,
Thanks for the response. I have followed your recommendation as follows:
1. In effect my dhcpd.conf now looks like this:
ddns-update-style interim;
ignore client-updates;
subnet 192.168.16.0 netmask 255.255.240.0 {
option routers 192.168.16.1;
option subnet-mask 255.255.240.0;
range dynamic-bootp 192.168.16.10 192.168.16.30;
default-lease-time 21600;
max-lease-time 43200;
host r02s01 {
hardware ethernet 00:A0:D1:E3:58:38;
fixed-address 192.168.17.11;
filename pxeboot;
option root-path 192.168.17.1:/export/images/NFSroot_gold/freebsd7_x64;
option host-name r02s01;
}
}
next-server 192.168.17.1;
2. Thereafter, I restarted the dhcpd service, and then rebooted my
freebsd client (r02s01) . Upon logging in, I checked its
configuration, and still the netmask reflects the 255.255.255.0
subnet:
r02s01# ifconfig -a
nfe0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu
1500 options=19bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4
ether 00:a0:d1:e3:58:38
inet 192.168.17.11 netmask 0xff00 broadcast 192.168.17.255
inet6 fe80::2a0:d1ff:fee3:5838%nfe0 prefixlen 64 scopeid 0x1
media: Ethernet autoselect (1000baseTX full-duplex,flag2)
** netmask 0xff00 - which means this, right:
Name Example
CIDR /24
Netmask255.255.255.0
Netmask (hex) 0xff00
Wilcard Bits 0.0.0.255
*sigh* ... am I missing something in my client side?
thanks in advance!

If your host declaration is outside the subnet declation the subnet
parameters are not sent, the client should then default to the netmask
/24 since 192.168 is in the old class C network range. Place the host
declaration inside the subnet declaration.

Re: FreeBSD PXE client not getting netmask config from DHCP server
I'd like to add another datapoint:
1. It seems that a fedora PXE client, honors the netmask parameter
passed by the DHPC server:
ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:A0:D1:E3:57:CA
inet addr:192.168.16.12 Bcast:192.168.31.255 Mask:255.255.240.0
inet6 addr: fe80::2a0:d1ff:fee3:57ca/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:74171 errors:0 dropped:0 overruns:0 frame:0
TX packets:45164 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:64499323 (61.5 MiB) TX bytes:8111327 (7.7 MiB)
Interrupt:23 Base address:0x2000
2. However, the FreeBSD server, stubbornly insists towards the
255.255.255.0 subnet
Both clients boot against the same DHCP server.
Any thoughts?
- thanks in advance.
