<p>fail2ban 在linux上是個很好用的軟體，可以幫忙阻絕很多沒事幹在亂踹的IP</p>
|
|
|
|
|
|
<p>但是很奇怪的是，在實務上會發現，有些IP會一再出現</p>
|
|
|
|
|
|
<p>有可能是被關了之後，時間到就放出來了吧…</p>
|
|
|
|
|
|
<p>加上之前手邊有自行維護了一堆黑名單</p>
|
|
|
|
|
|
<p>就想看看能不能把這些黑名單給加入fail2ban中</p>
|
|
|
|
|
|
<p>作法如下</p>
|
|
|
|
|
|
<p> </p>
|
|
|
|
|
|
<p>建立一個黑名單檔案</p>
|
|
|
|
|
|
<p>vim /etc/fail2ban/ip.blacklist</p>
|
|
|
|
|
|
<p>把手邊的黑名單都貼進去存檔</p>
|
|
|
|
|
|
<p>接著修改 /etc/fail2ban/action.d/iptables-multiport.conf</p>
|
|
|
|
|
|
<p>找到 actionstart的部分</p>
|
|
|
|
|
|
<p>加入
|
|
|
> cat /etc/fail2ban/ip.blacklist | while read IP; do iptables -I f2b-<name> 1 -s $IP -j DROP; done
|
|
|
修改後的 actionstart 區段看起來會像是這樣</p>
|
|
|
|
|
|
<p><img src="http://wp.cowbay.org/wp-content/uploads/2016/12/2016-12-20_15-12-42-1024x305.png" alt="2016-12-20_15-12-42" /></p>
|
|
|
|
|
|
<p>這一段是讓fail2ban 啟動的時候，會去檢查剛剛建立的 ip.blacklist 黑名單，然後把黑名單裡面的IP都丟去iptables 給擋掉</p>
|
|
|
|
|
|
<p>再來是修改actionban的部分，加入
|
|
|
> echo <ip> >> /etc/fail2ban/ip.blacklist
|
|
|
這是讓fail2ban 偵測並阻擋IP後，會自動把IP加入黑名單中</p>
|
|
|
|
|
|

|
|
|
|
|
|
<p> </p>
|
|
|
|
|
|
<p>這樣子應該就可以了…(吧) ….</p>
