_ 新しいノートPCの時刻補正

Lenovo Think pad X200 に Debian GNU/Linux Lenny を入れてから、設定するのを忘れていたものに、時刻補正がある。先日、友人に「ログを取るなら時刻同期大事だよね」という話をしていて、ハッと思い出した。

yabuki@yelona:~$ /usr/sbin/ntpdate -qu ntp.nict.jp
server 133.243.238.243, stratum 1, offset 0.348931, delay 0.10559
server 133.243.238.244, stratum 1, offset 0.348479, delay 0.10559
server 133.243.238.163, stratum 1, offset 0.349162, delay 0.10487
server 133.243.238.164, stratum 1, offset 0.344493, delay 0.11557
 3 Dec 12:59:12 ntpdate[32702]: adjust time server 133.243.238.163 offset 0.349162 sec

一般ユーザで、ntpdateを実行すれば、誤って時刻変更をしてしまう可能性もないから、ntpdate を導入してやっってみるといい。最初は2秒ぐらいずれてました。あわてて root で ntpdate を実行して、補正しましたよ。

_ UE-200TX-G(usb ethernet)

を購入、Debian GNU/Linux Lenny + kernel 2.6.27の環境でどんなdmesgがでるか表示してみた。 NetworkManager は、ちゃんと usb ethernet を認識している。

Lenovo Think Pad X200 に使っていた、 wire を usb nic につなぎ直してみたら、ちゃんと認識して通信し始めた。
