/tmpのファイルがいつの間にか消えてしまう。

/tmpのファイルがいつの間にか消えてしまう。

ある日設置したはずのファイルが/tmp配下に置いたファイルが削除されてしまう。

その処理を行っているのは/etc/cron.daily/tmpwatchでの処理で毎日4時に実行されてしまう。

/usr/sbin/tmpwatch 240 /tmp　←240時間アクセスされていない/tmpのファイルを削除
/usr/sbin/tmpwatch 720 /var/tmp　←720時間アクセスされていない/var/tmpのファイルを削除
for d in /var/{cache/man,catman}/{cat?,X11R6/cat?,local/cat?}; do
if [ -d “$d” ]; then
/usr/sbin/tmpwatch -f 720 $d　←/var/cache/manや/var/cache/catman以下の諸ファイルで720時間アクセスのないものを削除
fi
done

なぜこういった処理をしているかは、/tmpに大量のファイルが出来てしまってディスク容量
を圧迫する可能性がある。

そのため、cronで処理している。

原則として、保存しておきたいファイルは、/tmpに置かないという原則ですが、例外を作りたいということであれば数値をカスタマイズすればよいのでしょうかね。

ただ、編集してもOSのupdateがかかった先は、編集しても上書きされると思います。
その際には、再修正が必要。

ペッドボトルロケッドの2段式の切り離しが凄い。子供も楽しそうでしたね。

Xperiaを購入しました。

Xperiaを購入しました。色々アプリをインストールしてだいぶ使いやすかった。

デフォルトの状態だといろいろ、使いにくい点（例えばメールアプリfromのアドレスに送信者名がでてこない)
など結構正直使いにくいですが、今はカスタマイズしてだいぶいい感じになりました。

以下サイトで結構購入した際に、役に立ったサイトです。
まずはこのアプリをインストール！はじめてのXperia特集！

phpMyAdminへの攻撃について

2010年8月4日2017年2月21日 9821218212821 Leave a comment

phpMyAdminを狙った攻撃がありました。

最近WEBベースからのクラックが増えていると思います。phpmyadminをサーバへインスートールされている方は十分注意と対処をしてください。

「対処方法」

・.htaccessファイル等でBASIC認証をphpMyAdminにかけ、アクセスできるところを限定する。

・phpMyAdminのファイル名をユニークな推測されないものへ変更する方法。
・出来る限りphpMyAdminをインストールしない。

・カーネルのバージョンをあたらしいものへ変更する（root権限)を乗っ取られるのを防止するため。

・phpMyAdmin – 2.11.9.5もしくは、phpMyAdmin 3.1.31の最新版のものを利用する。
・config/config.inc.phpを有無を確認し、存在する場合は削除する。
