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

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。
