DHCPによるLAN接続について教えてください。

ubuntu9.04,DELLMini10vで使ってます。
ネットワークマネージャーの無線LANでは、ルーターを見つけることができるのですが
接続ができません。有線LANでも同様です。

IPアドレス、サブネットアドレス、ゲートウエイ、DHCPサーバ等を指定してあげると繋げることが
できます。

自動的にDHCPからIPアドレスを受けて接続する方法はありますか?
(windowsXPではできます)

よろしくお願いします。

Re: DHCPによるLAN接続について教えてください。

ネットワークマネージャのアプレットが(デフォルトでは)右上にでているかと思いますが、そこで自動を選んでもつながらないでしょうか。
ダメなら端末を開いて、例えば
grep -i networkmanager /var/log/* | grep "Sep 25"
みたいな感じでログになにか残っていないか探してみて下さい。
(日付は実行した日に合わせて変えて下さい)

Re: DHCPによるLAN接続について教えてください。

hmatsueさん、ありがとうございます。
今は、無線でIP指定して繋いでます。有線でも指定すればつながるのですけどねぇ。。。
有線で自動で接続したときのログです。
これを見ても、初心者なのでよくわかりません。よろしくお願いします。

Re: DHCPによるLAN接続について教えてください。

コード:

/var/log/syslog:Sep 26 00:44:36 minpa NetworkManager: <info>  Device 'eth0' DHCP transaction took too long (>45s), stopping it.

なぜかDHCPのトランザクションでこけてますね。
前回同様に端末で
grep -i dhcp /var/log/* | grep "Sep 26 06:5"
を実行してみてDHCP関連のログを確認してみて下さい。
最後の方の"Sep 26 06:5"は自動接続を試した日時に合わせて適宜変更願います。
上記の例は本日(9月26日)の06時50~59分のログだけ抜き出します。

Re: DHCPによるLAN接続について教えてください。

DHCPDICOVERで255.255.255.255とあるのはDHCPサーバを探すときのブロードキャストです。
その後192.168.1.1にサーバを見つけていて、そこから192.168.1.5を使うように指定がありました。
サーバ、クライアント共に、192.168.1.5で了解しているはずなのですが、
その後、また、アドレスを取りにいっています。
そこで質問ですが、

1. DHCP機能内蔵のルータのアドレスは192.168.1.1であっていますか。ネットワーク内にルーターが複数あったりしませんか。
2. ルーターのDHCPの設定でリースタイムはどのぐらいに設定されていますか。
3. 下記を端末から実行した結果を教えて下さい。

コード:

cat /etc/network/interfaces

4. 下記を端末から実行した結果を教えて下さい。

コード:

ifconfig
iwconfig

5. 下記を端末から実行してethernetに関連する部分を抜き出して教えて下さい。

コード:

lspci -v | less

最初はルータが2台、ネットワーク内にいたのでしょうか。それらは両方共DHCP
サーバとして働くものでしょうか。もしYESであれば、それぞれのIPアドレスと
grep -i dhcp /var/log/* | grep "Sep 26 06:5"
の結果に変化がないか教えて下さい(grepで抜き出す日時は適宜変更願います)。

2については根拠は無いのですが、無期限ではなく、適当な期限を設定したら状況
変わらないでしょうか。
問題発生箇所の切り分けのため、一度、試してみて下さい。

5について、RTL8101とubutnuで検索すると、いろいろ引っかかるようですが、
まだ見きれていません。DHCPだけで発生するH/W(やそのドライバ)起因不具合
というのも考えにくいですが。。

Re: DHCPによるLAN接続について教えてください。

手元のMini10vでは特に問題なく有線・無線ともにDHCPでアドレスが取れています。
なんとなく、DHCPサーバ側の不具合のような気もするので、
 ・とりあえず9.04を最新までアップデート
 ・DHCPサーバ(ブロードバンドルータ? 無線ルータ?)のファームウェアも最新にアップデート
してみてダメであれば、お使いの機材の型番を出して頂けると何か分かるかもしれません。

期限を切ったら、不思議にルーターよりIPを受信することができました!
何が原因かは、不明ですができました。不思議ですねぇ。。。
FONを繋いでこれからやってみます。

Re: DHCPによるLAN接続について教えてください。

自分の持っているルータはDHCPのリース期限無しという選択肢がないので、確認できませんでしたが、CG-WLBARAGLかdhclientのどちらかがおかしいのでしょうね。ググってもdhclientの方ではそういう話が引っかからなかったので、リース無期限のときのコレガのログを見せていただければ、なにか判るかも。ポイントは、
http://www.ietf.org/rfc/rfc2131.txt
の3.3に沿って「無期限」を通知しているかどうかでしょうか。
時間があるときにでも投稿いただけると幸いです。

Re: DHCPによるLAN接続について教えてください。

機種が違うかもしれませんが、こんな話を見つけました。
http://techno-st.net/2009/07/25/inspiron-mini-10v-debian---2.html

ログを見ると/var/log/syslog.0:Sep 26 00:12:03 minpa NetworkManager: <info>  eth0: driver is 'r8169'.
となっていて、r8169を読んでいますがこのサイトの記事だと
> 丁寧にも、また r8169 が読み込まれていますので、part1 の記事の手順に従って、r8101 のドライバを入れてあげてください。
となっています。もし機種が違い全然関係ないようでしたらすみません。このサイトの方だと
> Debian lenny だと、デフォルトで NIC 全滅
となっているようです。なんかバグなんでしょうか。

Re: DHCPによるLAN接続について教えてください。

確かにドライバが違ってますね。見落としていました。ただ、デバイス自体は通信できていて、DHCPでのトラブルのようなので、あまり関係ないような気はします。
最初、自分が不思議に思ったのは、
daemon.log:Sep 24 17:16:29 hmatsue dhclient: bound to 10.0.2.15 -- renewal in 37158 seconds.
のような行がない!ということだったのですが、見返してみると、dhcpで引っ掛けてもらったので見えなくて当然でしたね。。
近々、ルータを購入する予定なので、リース無期限の機能がついていれば、調べてみます。
# どっちかというと、ルータの返すDHCPACKの中身が怪しいんじゃないか思っています。
