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

TOP ↑ ↓

iptables 停止または iptables 設定+ポート指定

iptables 停止の場合

TOP ↑ ↓

# service iptables stop

iptables 設定の場合

TOP ↑ ↓

/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。
