一、解除IP限制

1.1、识别版本号

1.2、修改配置文件

一、解除IP限制

1.1、识别版本号

在浏览器中输入

 https://plugins.nessus.org/v2/plugins.php

1.2、修改配置文件

修改 plugin_feed_info.inc 文件

sudo find /opt -name plugin_feed_info.inc 

看不见,就用root打开

---

If it doesn't exist, create a new oneplugin_feed_info.inc

并将内容改为

（Replace the original file if any/opt/nessus/lib/nessus/plugin_feed_info.inc）

PLUGIN_SET = "202208020542";
PLUGIN_FEED = "ProfessionalFeed (Direct)";
PLUGIN_FEED_TRANSPORT = "Tenable Network Security Lightning";

---

将 /opt/nessus/lib/nessus/plugins/plugin_feed_info.inc 文件删除

（Or replace this one too）

rm -rf /opt/nessus/lib/nessus/plugins/plugin_feed_info.inc

1.3、重启服务

重启nessus服务

sudo service nessusd restart

1.4、访问

浏览器访问nessus（https://localhost:8843）

等待nessus初始化插件

设置页面显示 unlimited,则解除IP限制

二、Resolve plugin was removed

2.1、分析

Nessus服务每次重启后,都会重置plugin_feed_info.inc,会使nessus/plugins目录下所有的插件都被删除,无法扫描

 2.2、方法一：

Manually update the plugin package every time

pluginsThe content of the file can be obtained by updating the plugin again（Take advantage of that plugin package we got）

2.3、方法二：

先停止nessus服务,将nessus服务设置为手动

sudo systemctl disable nessusd

sudo service nessusd stop

---

It's the same operation after every reset,重新配置

Can be written as batch processing

sudo vim crack_nessus.sh

service nessusd stop;
cp /root/plugin_feed_info.inc /opt/nessus/var/nessus/;
rm -rf /opt/nessus/lib/nessus/plugins/plugin_feed_info.inc;
service nessusd start;

---

将crack_nessus.shWritten in the system startup script

每次重启,Release will be performed automaticallyIP限制

sudo chmod +x /etc/rc.d/rc.local
sudo vim /etc/rc.d/rc.local

---

添加如下内容到rc.local

/bin/bash /root/crack_nessus.sh

nessus解除IP限制

三、Scanning is fast with no results

3.1、分析

When creating a new scan item,很快就结束,无扫描结果

查看plugins目录内容是否被删除

sudo du -h /opt/nessus/lib/nessus/plugins

Generally check the file size

3.2、恢复

使用备份（The premise is that it is backed upplugins目录）

service nessusd stop;
rm -rf /opt/nessus/lib/nessus/plugins
cp -r ./plugins /opt/nessus/lib/nessus/
cp /root/plugin_feed_info.inc /opt/nessus/var/nessus/;
rm -rf /opt/nessus/lib/nessus/plugins/plugin_feed_info.inc;
service nessusd start;

然后打开浏览器,访问nessus（https://localhost:8843）
等待更新完成
