!!!CentOS-6

!!インストール
!CentOS-6 + RepoForge
*yum repository インストール
 # rpm -v --install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

*インストール
 # yum install netperf

!!FW設定

*iptables 停止または iptables 設定+ポート指定

!iptables 停止の場合
 # service iptables stop

!iptables 設定の場合
*/etc/sysconfig/iptables 追加設定
 -A INPUT -m state --state NEW -m tcp -p tcp --dport 12865:12866 -j ACCEPT
*標準 12865 ポートが制御用
*12866 ポートで試験するよう、netperf コマンドで指定
*指定がないと、ランダムに試験ポートが選ばれて iptables が拒否し失敗する。

!失敗時
