snort 抱怨 local.rules

我剛剛在 Fedora 20 上安裝了 snort-2.9.7.0，執行時出現錯誤：

% snort -c /etc/snort/snort.conf --dump-dynamic-rules=/tmp
Running in Rule Dump mode

我確實有 /etc/snort/snort.conf ，這是一個相關的片段：

var RULE_PATH /etc/snort/rules
include $RULE_PATH/local.rules

無法找到文件的原因可能是什麼？謝謝。

你有沒有嘗試過：

var RULE_PATH rules
include $RULE_PATH/local.rules
