FLORA 370の 再起動準備 完了しました。

FLORA 350

こちらは再起動させるだけです その後 FLORA 370 を 再起動するまで の 間 は 外部に 向けた サービスの停止時間になります。

nl:/var/log# shutdown -r now

Broadcast message from root (pts/1) (Fri May 28 21:35:55 2010):

IP Adr 192.168.24.9 として 再起動 しているようです。

FLORA 370

さて こちらも 再起動 させましょう

FLORA 370 再起動

当然ですが IP Adr 192.168.24.20 は 無くなります。

IP Adr 192.168.24.8 が 立ち上がった様です。

にゃんたろう 拝！
