 ローカルDHCP構築にて |

- はじめまして
早速ですが下記環境でローカルでDHCPサーバーを組もうとしています。
しかしローカル下のIPアドレスがうまく振られません。
ルータ サーバ
192.168.1.1 −−− 192.168.1.201(eth0)
192.168.2.253(eth1) −−(Hub)ーー (ローカルクライアント)
dhcpd.confは下記です。
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
ddns-update-style none;
use-host-decl-names on;
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
# localnet
subnet 192.168.2.0 netmask 255.255.255.0 {
option domain-name-servers 192.168.2.253;
authoritative;
allow client-updates;
allow unknown-clients;
max-lease-time 43200;
default-lease-time 21600;
option broadcast-address 192.168.2.255;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.2.16 192.168.2.240;
}

念のため、ルート設定も出しますと
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1

こんな感じです。
この状態で

なんて、一見動いてそうですが。eth1下のローカルマシンは、期待している
192.168.2.＊
のようなIPアドレスを振ってもらえません。
リンクランプは付いていて、お話はしてそうです。
ログを見ました

動いてそうですが、この後機器をつないでクライアントから覗くと
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−

(中略)
Autoconfiguration IP Address : 169.254.18.53
subetmask : 255.255.0.0
Default Gateway : (なし)

手な感じです。
ルート設がまずいのかと思えますが、如何様になおせばいいでしょうか、
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
の設定をためしに削除しましたが、これ、起動するとなぜか必ず復活して書き加えられます。
設定は全てWebminを使ってやっております。
対応御教授ください。

諦めかけのところへ投稿ありがとうございます。
実はNICどらいば問題と思い、カーネル再構築をかけて失敗し、システムごとダメになってしまったこともあり、
Fedoraの環境を７にあげて、自DNSに今は挑戦してます。
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
/etc/sysconfig/network 中に
DHCPDEV=eth1 を記述しました。
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
たしかeth指定はかけていましたが…今となっては確認もできず。
一段落してからまた実験してみます。
ありがとうございます。
