解決 netflow-tools 編譯錯誤

由於 cacti 有一個netflow viewer plugin, 但是從網站下載的 ftp://ftp.eng.oar.net/pub/flow-tools/flow-tools-0.66.tar.gz 或 ftp://ftp.eng.oar.net/pub/flow-tools/flow-tools-0.68.tar.gz 解開後，在 ./configure 指令沒有開問題，但用 make 時便出現無法編譯的錯誤，情況如下：
==============================================
# makeMaking all in lib
make[1]: Entering directory `/cacti/flow-tools-0.68/lib'
make all-am
make[2]: Entering directory `/cacti/flow-tools-0.68/lib'
source='ftio.c' object='ftio.o' libtool=no \

make[2]: *** [ftio.o] Error 1
make[2]: Leaving directory `/cacti/flow-tools-0.68/lib'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/cacti/flow-tools-0.68/lib'
make: *** [all-recursive] Error 1
===========================================

依照情況來看問題應該是 c 語言的語法有問題，所以就先修改 ftio.c 這個檔案，在錯誤的第2270行與2295行的程式改寫如下：

2270行原本程式碼：
(char*)ptr += nread;
改寫為：
ptr = (void*) ((char*) ptr) + nread ;

2296行原本程式碼：
(char*)ptr += nwritten;
改寫為：
ptr = (void*) (((char*) ptr) - nwritten) ;

將改寫後的程式存檔後再執行make 指今，發現原先的錯誤不會出現，但出現更多的相同錯誤在fttlv.c、ftchash.c 這個檔案，所以我們再按照相同方式一一修改，應該就可以了完成make動作，雖然仍會遇到一些警告但仍可以完成。

termcap.h 在 unbuntu 中可在 libncurses5-dev 套件找到

#sudo apt-get install libncurses5 libncurses5-dev

mysql.h 檔案在unbuntu中可在 libmysql++-dev 套件中找到

一般我們都認為會在 mysql-devel 套件中，現在只有 libmysql++-dev 套件。

#apt-get install libmysql++-dev

configure: error: C compiler cannot create executables解決方法

# apt-get install libc6-dev

configure: error: Unable to find C++ compiler解決方法

#sudo aptitude install build-essential

解決cacti的Mac Track Device中的 status error

要把 pfsense 放在 cacti 中的Mac Track Devices的設定, 一直會有 status error 的問題，原因是我一直沒注意 pfsense 的System Description Match會更 hostname 變動，所以可以用下列指令來檢查。
#/usr/bin/php -q /var/www/cacti/plugins/mactrack/mactrack_scanner.php -id=1 -d

在 pfsense 安裝 pfflowd

要讓 pfSense 具備 netflow 可以安裝 pfflowd 的 套件，如此就可以讓 pfSense 的流量狀況被網管系統掌握。

安裝 pfflowd 成簡單只要在 pfSense 的 System->Packages 下選擇就可以看到 pfflowd 的套件，雙擊就可以自動安裝。

接下來就可以到 Services 找到 pfflowd 的設定，然後將 Host 填入 netflow collector 的IP位置與設定 Port 參數為 2055 就可以完成設定。

記得要把 collector 的設備打開，應該就可以看到netflow的資料。

要看看是否有順利執行可以到 Status->Services 看看，若有Running就表示 netflow 已經可以正常運作。

Bacula Backup 安裝

Bacula 是一個 Linux 的 Open Source 的備份軟體，並適用於一般企業，可以讓管理者進行網路備份管理，復原和驗証電腦資料。

我們可以從 http://sourceforge.net/projects/bacula 來下載套件，目前我們可以用的最新版本是 2.4.4。

Step 1. 把套件取得解開到工作目錄

#tar -zxvf bacula-2.4.4.tar.gz
# cd bacula-2.4.4

Step 2. 準備進行套件的編譯

由於我是用 mysql 來做DB參數要用 --with-mysql，我用root安裝並要放程式放在 /root/bacula/bin 的目錄下，因此 configure 的參數如下：

#./configure --sbindir=$HOME/bacula/bin --sysconfdir=$HOME/bacula/bin --with-pid-dir=$HOME/bacula/bin/working --with-subsys-dir=$HOME/bacula/bin/working --enable-smartalloc --with-mysql --with-working-dir=$HOME/bacula/bin/working --with-dump-email=name@host.com --with-job-email=name@host.com --with-smtp-host=localhost

結果輸出如下：
checking for acltotext in -lsec... no
checking for pthread_create in -lpthread... yes

由於發現需要 termcap.h 的標頭檔案，而該檔案是在libtermcap-devel套件中, 所以我使用centos可以用 yum install libtermcap-devel來取得。
所以我們重新再作一次 ./configure

configure 都沒有錯誤訊息就可以進行 make 的動作。

#make

make 都沒有錯誤就可以進行 make install 來安裝套件

#make install

step 3. 在安裝完後要設定 mysql 的 datebase

在解開的 bacula-2.4.4 的 src/cat 下有一個 mysql 用的資料庫產生指令 make_mysql_tables來建立 database。

#cd src/cat
# ./make_mysql_tables

step 4. 要設定 bacula_sd 的 archive 設備

我們可以將目錄位置設給 bacula 做 archive 的設備.

#mkdir /root/bacula/archive

並在 bacula-sd.conf 設定相關目錄就可以用

Device {
Name = FileStorage
Media Type = File
Archive Device = /root/bacula/archive
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = no Always
Open = no
}

正確完成之後我們要再建一個 bacula 專用的帳號，並設定相關權限就算完成 bacula 的安裝。

移除Microsoft Office 2007的中文輸入法

我在Vista 64Bit版本安裝完Microsoft Office 2007後，中文輸入法就有問題，原因是沒辦法用Ctrl-Shift來切換輸入法，所以解決辦法就是只解除Microsoft Office 2007的IME 2007套件，解除完回到Vista 內建的輸入法就一除正常。

解除方式如下:
C:\>msiexec.exe /X {90120000-0028-0404-0000-0000000FF1CE}

安裝ntop上的Local Network Traffic Map

參考文件:http://www.graphviz.org/Download_linux_rhel.php

由於ntop使用的Local Network Traffic Map需要 dot 的軟體套件才可以正確的呈現.

step 1.
若是用Centos請先行設定 yum 的設定，在目錄 /etc/yum.repos.d/ 下，新增 graphviz-rhel.repo 檔案，可直接下載檔案http://www.graphviz.org/graphviz-rhel.repo

step 2.
確認yum是否設定有正確
#yum list available 'graphviz*'

step 3.
執行安裝
#yum install 'graphviz*'
若安裝沒有問題應該會有 /usr/bin/dot 這個檔案。

step 4.
設定 ntop 的Local Network Traffic Map，若有需要必須增加 ntop 的Preference設定dot.path並填入參數/usr/bin/dot

step 5.
若一切正常使可以在 ntop 看到Local Network Traffic Map


附記
若有發生以下狀況問題:

可以試試下列方法.

#wget ftp://fr2.rpmfind.net/linux/dag/redhat/el5/en/i386/dag/RPMS/graphviz-2.8-1.el5.rf.i386.rpm
#rpm -ivh graphviz-2.8-1.el5.rf.i386.rpm
#yum install graphviz.i386

應該可以解決。

在cacti安裝ntop

參考文件: http://openmaniak.com/cacti_plugins.php

step1. 套件安裝
#apt-get install ntop

step2. 設定與執行
# ntop -u ntop -w 3000
這樣子在起動ntop後，第一次只要再輸入設定admin的確password就完成了並會自動執行。

step3. 調整與使用
若有安裝防火牆！要記得打開 tcp port 3000.
另外要使 ntop 改成 deamon 模式也要進入 ntop 後調整 config.
打開IE瀏覽器 http://ntop server ip:3000便可以進入.

step4. 安裝cacti的ntop plugin
#wget http://cactiusers.org/downloads/ntop.gzip
#tar -zxvf ntop.gzip
#move ntop /cacti/plugins/

step5. 修改 cacti plugins 設定文件
#vi /cacti/include/globol.php
在正碓的位子加入
$plugins[] = 'ntop';
存檔就完成了.

ps. 若看不到ntop 的標題頁，說得把 console->user management的view ntop打開.
