■ [osiris]最新版osiris-4.1.8をTigerへインストールする
Tigerをインストールしたので最新版osirisで某噂の検証をしてみる。osirisのHP(http://osiris.shmoo.com/)から最新版の4.1.8をダウンロードする。なんか、S/MIMEモジュールとかいろいろ機能拡張されているなぁ。とりあえず今回は本体のみダウンロード。TigerにはあらかじめXcodeをインストールしておく必要がある。
最新版ではWindows2003Serverなどの対応が追加されている他filterの編集方法などが変更されている(後述)ので注意が必要である。
注)4月30日現在下記設定をしてもいくつか不具合がみられるので注意。
Filterの設定が適切に反映されていないようにみえる
osirisを再起動すると管理対象ホストの設定の一部が無効になる
しかたないで3.0.4をインストールしてみたのだが、こちらはちゃんと動作しているようだ。なんだかなぁ。とりえあず検証用途には3.0.4をオススメ。(誰に?)
■ [osiris]configure
ダウンロードしたファイルを展開する。
[code]$ tar zxvf ./osiris-4.1.8.tar.gz
$ ls ./osiris-4.1.8
AUTHORS INSTALL Makefile.in TODO bootstrap config.sub depcomp mkinstalldirs
COPYING LICENSE NEWS acinclude.m4 config.guess configure install-sh src
ChangeLog Makefile.am README aclocal.m4 config.h.in configure.ac missing[/code]
まずはconfigureオプションの調査だが、最新版ももちろんOSX標準対応なのでオプションは特に不要。
[code]
$ ./configure

agent: create scan agent installer package.

これでconfigure完了。
■ [osiris]osirisクライアント/コンソールを個別にmake
osirisではマネージメントコンソールとスキャンクライントが連携して動作する仕様で、管理用のマシンにはマネージメントコンソール、管理対象にはスキャンクライアントと別々にインストールして設置することが可能である。多数の管理対象がある場合にはコンソール/クライアントを個別にmakeしてインストールパッケージを作っておくことができる。
[code]$ make console

detected. Because of disk space, this option is not recommended
unless your security policy requires it. (yes/no) [no]:

changes are reported only once, and the baseline database is
automatically set when changes are detected. (yes/no) [yes]:
↑変更を自動承認する設定 これをnoにすると承認するまで変更通知メールが何度も来る
=> purge database store? Enabling this option means that none
of the scan databases are saved. That is, whenever the baseline
database is set, the previous one is deleted. (yes/no): [yes]:
↑常に最新のスキャンDBだけで運用する設定
Notifications:

[ scheduling information for myhost ]
Scheduling information consists of a start time and a frequency value.
The frequency is a specified number of minutes between each scan, starting
from the start time. The default is the current time. Specify the start
time in the following format: mm/dd/yyyy HH:MM
enter the start date and time
using ‘mm/dd/yyyy HH:MM’ format: [Sat Apr 30 13:07:15 2005]

Is this correct (y/n)? y
>>> new host (myhost) has been created.
