s25rのログ検索のためpermisssion変更†

拒絶ログソーティングスクリプト FreeBSD 9.0用†

オリジナルのままだとエラーするので、ちょっと改訂。

s25r_s.cgi

【変えた所】

• 何故か手元のmail server だと、charset=iso-8859-1をいれないと駄目っぽかった。
• あと、gawkをインストールしても、broken pipeになるっぽいので、gawk を awk にした。

試しに実行してみると、

[Thu Aug 23 08:26:18 2012] [error] [client 210.255.122.209] /usr/local/www/apache22/cgi-bin/s25r.cig: gawk: not found

というエラー(´・ω・`)なので、

hotshot# portinstall japanese/gawk
hotshot# rehash

した。けど、何故か broken pipe の嵐になるので、gawk やめて awk に・・・ｗ

必要な設定†

　HTTPデーモンの権限でメールログファイルが読めるようにアクセス権を設定。

hotshot# chmod 644 /var/log/maillog*
