/* About ----- This directory contains extra files to make the 'fancy urls' feature even more fancier, by eliminating the 'index.php'-part of the URL Installation ------------ 1. Copy all files in this directory (except for index.html) to your main nucleus dir (where your index.php and action.php file are) If you have an already existing .htaccess file (most ftp-programs don't show hidden files by default, so don't start uploading it without checking your server). If you do, download that old one first, and copy the contents of the new .htaccess file (from the fancyurls folder) in your old one, and upload that... 2. Edit this file so that $CONF['Self'] points to your main directory. NOTE: this time, and only this time, the URL should NOT end in a slash 3. Also edit the $CONF['Self'] variable in your index.php, if you don't want to end up with index.php/item/1234 urls when people come via that way 4. Enable 'Fancy URLs' in the Nucleus admin area (nucleus management / edit settings) 5. Off you go! If it doesn't work: ------------------- Remove the files again (don't forget the hidden file .htaccess). Voila. */ // remember: this URL should _NOT_ end with a slash. $CONF['Self'] = 'http://www.momoso-net.com/~ms08'; ?>
2006-03-03: Clamでウィルス対策(メール編)
シジミを使った料理でメールにひそむウィルスを調理。クラムチャウダとか日本人ならやっぱりしじみの味噌汁が最高!ハマグリならやはり「その手は桑名の焼きハマグリ」でしょうか!
という事でClam AntiVirusの導入です。しんぱいはClamなやつでウィルス見つけても口を割らないかも?SPAM(スパム)ポークランチョンミートに続く食べ物対策シリーズ第2弾です。
まずはパッケージの確認
gentooez8 ~ # emerge -pv clamav
These are the packages that I would merge, in order:
Calculating dependencies ...done!
[ebuild N ] dev-libs/gmp-4.1.4-r3 -doc -nocxx 1,641 kB
[ebuild N ] app-antivirus/clamav-0.88 +crypt -mailwrapper +milter (-selinux) 4,457 kB
Total size of downloads: 6,099 kB
sendmailで使うためにUSEにmilterを追加します。それにしてもなぜGMPがついてくるのか?
GMP(GNU multiple precision arithmetic library)てなことで何桁もの円周率の計算を早くやってくれる数値計算ライブラリなのですが(それだけじゃないですけど)
ではインストール
gentooez8 ~ # emerge clamav
clamd定義ファイルの確認
gentooez8 ~ # vi /etc/clamd.conf
メールのチェックが目的なのでもちろんこの辺りを修正

#START_MILTER=no sendmailでフィルタ掛けるのでyesにします。
START_MILTER=yes
MILTER_SOCKET="/var/run/clamav/clmilter.sock"
MILTER_OPTS="-m 10 --timeout=0"
sendmailの設定
gentooez8 ~ # vi /etc/mail/sendmail.mc
こんなのを追加しなさいと
INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clamav/clmilter.sock, F=, T=S:4m;R:4m')dnl
define(`confINPUT_MAIL_FILTERS', `clmilter')dnl
そしてCFの作成
gentooez8 ~ # cd /etc/mail
gentooez8 mail # m4 sendmail.mc > sendmail.cf
デーモンの起動
gentooez8 mail # /etc/init.d/clamd start
gentooez8 mail # /etc/init.d/sendmail restart
これも忘れずに
gentooez8 mail # rc-update -a clamd default
そんじゃテストしてみよう

OKってことでしょうか。
次に無害なウィルスをダウンロードしてこのへんにあるのでそれを添付して送ってみる。ちなみに自分以外に送っちゃだめですよ。絶対!!!
でもAVGとかインストールしているPCからは送れません。ちゃんとブロックしてますからね〜!

ちょっと長いので省略します。送ったテキスト文なんかも書かれています。
大事なのは-----でかこまれている文章ですね。内容は・・・・・・・・
「メールを送った相手は天然パーマだった。」実際に当たってるがそんなことは書かれていない。
相手のメール管理者が「ClamAVって貝ヤローがウィルスだと判断したので届けずに破棄したぜ!」ごめんよ
みたいなことが書いてあればわかるのにね!
まあそんなこんなでとりあえず導入完了しにます。
焼きハマグリが食いたい。3月だけどまだ大丈夫かな?食べそこなうと秋まで食べれないよね。卵産んでるやつなんか食べたひにゃ〜 キャー助けてーって事になりますからね。
